1.创建四个项目

spring_dubbo

    wms-api      打成jar    wms-client   打成war包    wms-manager  打成war包    wms-parent   打成pom包

这里写图片描述

使用快速创建Maven项目，例如：

2.给pom文件 添加依赖包

wms-client :

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">  <modelVersion>4.0.0</modelVersion>  <parent>    <groupId>com.xinyi.wms</groupId>    <artifactId>wms-parent</artifactId>    <version>1.0</version>  </parent>  <groupId>com.xinyi.wms</groupId>  <artifactId>wms-client</artifactId>  <version>1.0</version>  <packaging>war</packaging>  <dependencies>  <!-- 添加依赖的接口 -->    <dependency>        <groupId>com.xinyi.wms</groupId>        <artifactId>wms-api</artifactId>        <version>1.0</version>    </dependency>  <!-- 添加dubbo依赖包 -->    <dependency>              <groupId>com.alibaba</groupId>              <artifactId>dubbo</artifactId>              <version>2.5.3</version>      </dependency>      <dependency>          <groupId>org.springframework</groupId>          <artifactId>spring-context</artifactId>          <version>4.1.6.RELEASE</version>      </dependency>   <!-- 添加zookeeper依赖包 -->    <dependency>        <groupId>com.101tec</groupId>        <artifactId>zkclient</artifactId>        <version>0.2</version>    </dependency>    <dependency>        <groupId>org.apache.zookeeper</groupId>        <artifactId>zookeeper</artifactId>        <version>3.4.5</version>    </dependency>  </dependencies>   </project>

wms-manager:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">  <modelVersion>4.0.0</modelVersion>  <parent>    <groupId>com.xinyi.wms</groupId>    <artifactId>wms-parent</artifactId>    <version>1.0</version>  </parent>  <groupId>com.xinyi.wms</groupId>  <artifactId>wms-manager</artifactId>  <version>1.0</version>  <packaging>war</packaging><dependencies>  <!-- 添加依赖的接口 -->    <dependency>        <groupId>com.xinyi.wms</groupId>        <artifactId>wms-api</artifactId>        <version>1.0</version>    </dependency>  <!-- 添加dubbo依赖包 -->    <dependency>              <groupId>com.alibaba</groupId>              <artifactId>dubbo</artifactId>              <version>2.5.3</version>      </dependency>      <dependency>          <groupId>org.springframework</groupId>          <artifactId>spring-context</artifactId>          <version>4.1.6.RELEASE</version>      </dependency>   <!-- 添加zookeeper依赖包 -->    <dependency>        <groupId>com.101tec</groupId>        <artifactId>zkclient</artifactId>        <version>0.2</version>    </dependency>    <dependency>        <groupId>org.apache.zookeeper</groupId>        <artifactId>zookeeper</artifactId>        <version>3.4.5</version>    </dependency>  </dependencies>   </project>

3.编写

  1. 实体类
  2. 服务的接口

这里写图片描述

P.S：
一定要实现序列化接口，因为RPC底层就是socket协议序列化反序列化进行传输编译的

package com.xinyi.wms.api.entity;import java.io.Serializable;public class Product implements Serializable{    private static final long serialVersionUID = 7678537153669113018L;    private String name;    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }}

接口：

package com.xinyi.wms.api.service;import com.xinyi.wms.api.entity.Product;public interface IProductService {    public Product getProduct(Product product);}

4.编写服务

这里写图片描述

package com.xinyi.wms.client.serviceImpl;import com.xinyi.wms.api.entity.Product;import com.xinyi.wms.api.service.IProductService;public class ProductServiceImpl implements IProductService{    public Product getProduct(Product product) {        product.setName("生活不止眼前的苟且,还有诗和远方的田野");        return product;    }}

5.编写服务端配置

这里写图片描述

创建xml文件，并命名:

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"    xsi:schemaLocation="http://www.springframework.org/schema/beans     http://www.springframework.org/schema/beans/spring-beans.xsd     http://code.alibabatech.com/schema/dubbo     http://code.alibabatech.com/schema/dubbo/dubbo.xsd ">    <bean id="productService" class="com.xinyi.wms.client.serviceImpl.ProductServiceImpl" />    <!-- 配置服务名 -->    <dubbo:application name="wms-client" />    <!-- 配置注册中心 -->    <dubbo:registry address="zookeeper://127.0.0.1:2181" register="true"/>    <!-- 配置rpc的协议 -->    <dubbo:protocol name="dubbo" port="20880" />    <!--发布服务  -->    <dubbo:service interface="com.xinyi.wms.api.service.IProductService" ref="productService" /></beans>

6.配置开启zookeeper注册中心

解压 zookeeper-3.4.5.jar包: （并且创建 data 和 log 目录）

这里写图片描述

找到对应的conf目录，将 zoo_sample.cfg 文件名改为 zoo.cfg，并且添加

  1. 地址磁盘备份的路径
  2. 存放日志磁盘的路径
  3. 端口号
# The number of milliseconds of each ticktickTime=2000# The number of ticks that the initial # synchronization phase can takeinitLimit=10# The number of ticks that can pass between # sending a request and getting an acknowledgementsyncLimit=5# the directory where the snapshot is stored.# do not use /tmp for storage, /tmp here is just # 内存服务地址的快照,地址的磁盘路径备份dataDir=F://dubbo/zookeeper-3.4.5/data#存放日志磁盘的路径dataDir=F://dubbo/zookeeper-3.4.5/log#端口号clientPort=2181## Be sure to read the maintenance section of the # administrator guide before turning on autopurge.## http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance## The number of snapshots to retain in dataDir#autopurge.snapRetainCount=3# Purge task interval in hours# Set to "0" to disable auto purge feature#autopurge.purgeInterval=1

7.添加 log4j 日志文件

# Global logging configurationlog4j.rootLogger=debug, stdout# MyBatis logging configuration...log4j.logger.com.xinyi.wms.client.test.App=TRACE# Console output...log4j.appender.stdout=org.apache.log4j.ConsoleAppenderlog4j.appender.stdout.layout=org.apache.log4j.PatternLayoutlog4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

8.开启zookeeper注册中心、编写并开启服务

双击开启：

这里写图片描述

开启服务测试类：

package com.xinyi.wms.client.test;import java.io.IOException;import org.springframework.context.support.ClassPathXmlApplicationContext;public class App {    public static void main(String[] args) {        ClassPathXmlApplicationContext context=new ClassPathXmlApplicationContext(        new String[]{"application-client.xml"});          context.start();          System.err.println("启动成功....");         try {            System.in.read();        } catch (IOException e) {            e.printStackTrace();        }      }}

9.编写客户端配置

这里写图片描述

application-client.xml:

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"    xsi:schemaLocation="http://www.springframework.org/schema/beans     http://www.springframework.org/schema/beans/spring-beans.xsd     http://code.alibabatech.com/schema/dubbo     http://code.alibabatech.com/schema/dubbo/dubbo.xsd ">    <!-- 配置服务名 -->    <dubbo:application name="wms-client" />    <!-- 配置注册中心 -->    <dubbo:registry address="zookeeper://127.0.0.1:2181" register="true"/>    <!--引用服务  -->    <dubbo:reference interface="com.xinyi.wms.api.service.IProductService" id="productService"/></beans>

10.编写测试类

package com.xinyi.wms.manager.test;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.xinyi.wms.api.entity.Product;import com.xinyi.wms.api.service.IProductService;public class App {    public static void main(String[] args) {        ClassPathXmlApplicationContext context=new ClassPathXmlApplicationContext(          new String[]{"application-client.xml"});         context.start();        Product product = new Product();        IProductService productService  = (IProductService) context.getBean("productService");        product = productService.getProduct(product);        System.err.println(product.getName());    }}

11.运行main方法，控制台打印出:

生活不止眼前的苟且,还有诗和远方的田野

P.S：

  1. 先将wms-parent进行install，之后是wms-api…

  2. 启动服务时控制台显示log4j字样时，检查一下有没有添加log4j.properties文件

  3. 如果dubbo标签报错时，度娘一下 dubbo.xsd文件并且下载安装

继续整合Mybatis:

1.在wms-client文件中继续添加依赖包

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

2.编写配置文件(在wms-client项目下添加:)

  1. generatorConfig.xml 生成mybatis相关的Java文件
  2. myBatis-config.xml mybatis的配置文件
  3. conf-db.properties 连接池配置文件
  4. application-server.xml spring的主配置文件

generatorConfig.xml ：（在Maven-Build下添加启动命令：mybatis-generator:generate）

  1. 修改数据库连接信息
  2. 修改实体类包路径
  3. 修改mapper的映射路径
  4. 修改需要自生成的表名

添加代码生成器配置:

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE generatorConfiguration  PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN""http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"><!-- 配置生成器 --><generatorConfiguration>    <context id="mysql" defaultModelType="hierarchical" targetRuntime="MyBatis3Simple">        <!-- 自动识别数据库关键字，默认false，如果设置为true，根据SqlReservedWords中定义的关键字列表； 一般保留默认值，遇到数据库关键字（Java关键字），使用columnOverride覆盖 -->        <property name="autoDelimitKeywords" value="false" />        <!-- 生成的Java文件的编码 -->        <property name="javaFileEncoding" value="UTF-8" />        <!-- beginningDelimiter和endingDelimiter：指明数据库的用于标记数据库对象名的符号，比如ORACLE就是双引号，MYSQL默认是`反引号； -->        <property name="beginningDelimiter" value="`" />        <property name="endingDelimiter" value="`" />        <!-- 注释生成器 -->        <commentGenerator>            <property name="suppressDate" value="true"/>            <property name="suppressAllComments" value="true" />        </commentGenerator>        <!-- 必须要有的，使用这个配置链接数据库 @TODO:是否可以扩展 -->        <jdbcConnection driverClass="com.mysql.jdbc.Driver"            connectionURL="jdbc:mysql:///xinyi_wms" userId="root" password="admin">            <!-- 这里面可以设置property属性，每一个property属性都设置到配置的Driver上 -->        </jdbcConnection>        <!-- java模型创建器，是必须要的元素 负责：1，key类（见context的defaultModelType）；2，java类；3，查询类             targetPackage：生成的类要放的包，真实的包受enableSubPackages属性控制； targetProject：目标项目，指定一个存在的目录下，生成的内容会放到指定目录中，如果目录不存在，MBG不会自动建目录 -->        <javaModelGenerator targetPackage="com.xinyi.wms.client.entity" targetProject="src/main/java">            <!-- for MyBatis3/MyBatis3Simple 自动为每一个生成的类创建一个构造方法，构造方法包含了所有的field；而不是使用setter； -->            <property name="constructorBased" value="false" />            <!-- for MyBatis3 / MyBatis3Simple 是否创建一个不可变的类，如果为true， 那么MBG会创建一个没有setter方法的类，取而代之的是类似constructorBased的类 -->            <property name="immutable" value="false" />        </javaModelGenerator>        <!-- 生成SQL map的XML文件生成器， 注意，在Mybatis3之后，我们可以使用mapper.xml文件+Mapper接口（或者不用mapper接口），             或者只使用Mapper接口+Annotation，所以，如果 javaClientGenerator配置中配置了需要生成XML的话，这个元素就必须配置             targetPackage/targetProject:同javaModelGenerator -->        <sqlMapGenerator targetPackage="com.xinyi.wms.client.mapper"            targetProject="src/main/java">            <!-- 在targetPackage的基础上，根据数据库的schema再生成一层package，最终生成的类放在这个package下，默认为false -->            <property name="enableSubPackages" value="true" />        </sqlMapGenerator>        <!-- 对于mybatis来说，即生成Mapper接口，注意，如果没有配置该元素，那么默认不会生成Mapper接口 targetPackage/targetProject:同javaModelGenerator             type：选择怎么生成mapper接口（在MyBatis3/MyBatis3Simple下）：            1，ANNOTATEDMAPPER：会生成使用Mapper接口+Annotation的方式创建（SQL生成在annotation中），不会生成对应的XML；             2，MIXEDMAPPER：使用混合配置，会生成Mapper接口，并适当添加合适的Annotation，但是XML会生成在XML中；             3，XMLMAPPER：会生成Mapper接口，接口完全依赖XML；             注意，如果context是MyBatis3Simple：只支持ANNOTATEDMAPPER和XMLMAPPER -->        <javaClientGenerator targetPackage="com.xinyi.wms.client.mapper"            type="XMLMAPPER" targetProject="src/main/java">            <!-- 在targetPackage的基础上，根据数据库的schema再生成一层package，最终生成的类放在这个package下，默认为false -->            <property name="enableSubPackages" value="true" />            <!-- 可以为所有生成的接口添加一个父接口，但是MBG只负责生成，不负责检查 <property name="rootInterface"                 value=""/> -->        </javaClientGenerator>        <table tableName="product">            <!-- 参考 javaModelGenerator 的 constructorBased属性 -->            <property name="constructorBased" value="false" />            <generatedKey column="id" sqlStatement="JDBC" />        </table>        </context></generatorConfiguration>

myBatis-config.xml :

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE configuration  PUBLIC "-//mybatis.org//DTD Config 3.0//EN"  "http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration>    <settings>        <setting name="lazyLoadingEnabled" value="false"/>        <setting name="aggressiveLazyLoading" value="false"/>        <setting name="lazyLoadTriggerMethods" value="clone"/>    </settings></configuration>

conf-db.properties ：

db.driver=com.mysql.jdbc.Driverdb.url=jdbc:mysql://192.168.11.133:3306/xinyi_wms?createDatabaseIfNotExist=truedb.username=rootdb.password=admindb.timeout=124654

服务端 application-client.xml : 此处需要添加对应的xsd文件

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xmlns:context="http://www.springframework.org/schema/context"       xmlns:aop="http://www.springframework.org/schema/aop"       xmlns:tx="http://www.springframework.org/schema/tx"       xmlns:mvc="http://www.springframework.org/schema/mvc"        xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"        xsi:schemaLocation="            http://www.springframework.org/schema/beans             http://www.springframework.org/schema/beans/spring-beans.xsd            http://www.springframework.org/schema/context             http://www.springframework.org/schema/context/spring-context.xsd            http://www.springframework.org/schema/aop             http://www.springframework.org/schema/aop/spring-aop.xsd            http://www.springframework.org/schema/tx             http://www.springframework.org/schema/tx/spring-tx.xsd            http://www.springframework.org/schema/mvc             http://www.springframework.org/schema/mvc/spring-mvc.xsd            http://code.alibabatech.com/schema/dubbo             http://code.alibabatech.com/schema/dubbo/dubbo.xsd">    <context:property-placeholder location="classpath:conf-*.properties"/>    <mvc:annotation-driven />    <context:annotation-config/>    <context:component-scan base-package="com.xinyi.wms"/>    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">        <property name="driverClassName" value="${db.driver}"/>        <property name="url" value="${db.url}"/>        <property name="username" value="${db.username}"/>        <property name="password" value="${db.password}"/>    </bean>    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">        <property name="dataSource" ref="dataSource"/>        <property name="configLocation" value="classpath:myBatis-config.xml"/>        <property name="typeAliasesPackage" value="com.xinyi.wms"/>        <property name="mapperLocations" value="classpath:com/xinyi/wms/*/mapper/*Mapper.xml"/>    </bean>    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">        <property name="dataSource" ref="dataSource"/>    </bean>    <tx:advice id="advice" transaction-manager="transactionManager">        <tx:attributes>            <tx:method name="list*" read-only="true"/>            <tx:method name="get*" read-only="true"/>            <tx:method name="query*" read-only="true"/>            <tx:method name="*"/>        </tx:attributes>    </tx:advice>    <aop:config>        <aop:pointcut expression="execution(* com.xinyi.wms..service.*Service.*(..))" id="pointCut"/>        <aop:advisor advice-ref="advice" pointcut-ref="pointCut"/>    </aop:config>    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">        <property name="basePackage" value="com.xinyi.wms.client.mapper"/>    </bean>    <!--    <bean id="productService" class="com.xinyi.wms.client.serviceImpl.ProductServiceImpl" />    -->    <!-- 配置服务名 -->    <dubbo:application name="wms-client" />    <!-- 配置注册中心 -->    <dubbo:registry address="zookeeper://127.0.0.1:2181" register="true"/>    <!-- 配置rpc的协议 -->    <dubbo:protocol name="dubbo" port="20880" />    <!--发布服务  -->    <dubbo:service interface="com.xinyi.wms.api.service.IProductService" ref="productService" /></beans>

3.编写服务接口

1.拷贝实体类
这里写图片描述

编写服务:

这里写图片描述

package com.xinyi.wms.client.serviceImpl;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import com.xinyi.wms.api.entity.Product;import com.xinyi.wms.api.service.IProductService;import com.xinyi.wms.client.mapper.ProductMapper;@Service("productService")public class ProductServiceImpl implements IProductService{    @Autowired    private ProductMapper dao;    @Override    public int deleteByPrimaryKey(Long id) {        // TODO Auto-generated method stub        return 0;    }    @Override    public int insert(Product record) {        // TODO Auto-generated method stub        return 0;    }    @Override    public Product selectByPrimaryKey(Long id) {        // TODO Auto-generated method stub        return null;    }    @Override    public List<Product> selectAll() {        return dao.selectAll();    }    @Override    public int updateByPrimaryKey(Product record) {        // TODO Auto-generated method stub        return 0;    }}

4.启动服务 : 即上文写的wms-client项目下的test包中的App文件

P.S： 启动之前，先开启zookeeper注册中心

客户端整合SpringMVC

1.添加客户端(后台) application-client.xml 的依赖包

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xmlns:context="http://www.springframework.org/schema/context"       xmlns:aop="http://www.springframework.org/schema/aop"       xmlns:tx="http://www.springframework.org/schema/tx"       xmlns:util="http://www.springframework.org/schema/util"       xmlns:mvc="http://www.springframework.org/schema/mvc"        xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"        xsi:schemaLocation="            http://www.springframework.org/schema/beans             http://www.springframework.org/schema/beans/spring-beans.xsd            http://www.springframework.org/schema/context             http://www.springframework.org/schema/context/spring-context.xsd            http://www.springframework.org/schema/aop             http://www.springframework.org/schema/aop/spring-aop.xsd            http://www.springframework.org/schema/tx             http://www.springframework.org/schema/tx/spring-tx.xsd            http://www.springframework.org/schema/util            http://www.springframework.org/schema/util/spring-util.xsd            http://www.springframework.org/schema/mvc             http://www.springframework.org/schema/mvc/spring-mvc.xsd            http://code.alibabatech.com/schema/dubbo             http://code.alibabatech.com/schema/dubbo/dubbo.xsd">    <context:property-placeholder location="classpath:conf-*.properties"/>    <!-- 0.开启注解扫描 -->    <mvc:annotation-driven />    <context:component-scan base-package="com.xinyi.wms" />    <!--配置freeMarker的模板路径 -->    <bean        class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">        <!-- 配置freemarker的文件编码 -->        <property name="defaultEncoding" value="UTF-8" />        <!-- 配置freemarker寻找模板的路径 -->        <property name="templateLoaderPath" value="/WEB-INF/views/" />    </bean>    <!--freemarker视图解析器 -->    <bean id="viewResolver"        class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">        <!-- 是否在model自动把session中的attribute导入进去; -->        <property name="exposeSessionAttributes" value="true" />        <!-- 配置逻辑视图自动添加的后缀名 -->        <property name="suffix" value=".ftl" />        <!-- 配置视图的输出HTML的contentType -->        <property name="contentType" value="text/html;charset=UTF-8" />    </bean>    <!-- 使用Spring+quartz完成定时任务 -->    <!-- 配置作业类 -->    <bean        class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">        <property name="messageConverters">            <util:list id="beanList">                <ref bean="mappingJacksonHttpMessageConverter" />            </util:list>        </property>    </bean>    <bean id="mappingJacksonHttpMessageConverter"        class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">        <property name="supportedMediaTypes">            <list>                <value>text/html;charset=UTF-8</value>            </list>        </property>    </bean>    <!--处理上传 -->    <bean        class="org.springframework.web.multipart.commons.CommonsMultipartResolver"        id="multipartResolver">        <property name="maxUploadSize" value="100000000" />    </bean>    <!-- 配置服务名 -->    <dubbo:application name="wms-client" />    <!-- 配置注册中心 -->    <dubbo:registry address="zookeeper://127.0.0.1:2181" register="true"/>    <!--引用服务  -->    <dubbo:reference interface="com.xinyi.wms.api.service.IProductService" id="productService"/></beans>

编写 web.xml 配置

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"      xmlns="http://java.sun.com/xml/ns/javaee"      xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"      version="3.0">   <!-- 用于管理请求相关内容的监听器,只有配置了这个监听器才能使用RequestContextHolder -->  <listener>    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>  </listener>  <!-- 设置Spring容器加载配置文件路径 -->  <servlet>    <servlet-name>springMVC</servlet-name>    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    <init-param>      <param-name>contextConfigLocation</param-name>      <param-value>classpath:application-client.xml</param-value>    </init-param>    <load-on-startup>1</load-on-startup>  </servlet>  <servlet-mapping>    <servlet-name>springMVC</servlet-name>    <url-pattern>*.do</url-pattern>  </servlet-mapping>  <!-- 配置字符编码过滤器 -->  <filter>    <filter-name>characterEncoding</filter-name>    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>    <init-param>      <param-name>encoding</param-name>      <param-value>utf-8</param-value>    </init-param>  </filter>  <filter-mapping>    <filter-name>characterEncoding</filter-name>    <url-pattern>*.do</url-pattern>  </filter-mapping>  <!-- 默认首页 -->  <welcome-file-list>    <welcome-file>        /index.html    </welcome-file>  </welcome-file-list></web-app>

编写一个controller

package com.xinyi.wms.client.controller;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;import com.xinyi.wms.api.service.IProductService;@Controllerpublic class ProductController {    @Autowired    IProductService productService;    @RequestMapping("/getAllProduct.do")    public String getAllProduct(Model model){        model.addAttribute("list",productService.selectAll());        return "product_list";    }}

编写ftl视图映射

这里写图片描述

<!DOCTYPE html><html><head><meta charset="UTF-8"><title>Insert title here</title></head><body>  HelloWorld....</body></html>

配置tomcat启动 –> Maven-Build

这里写图片描述

同理，将wms-client 也配置成tomcat启动；
也需要添加 web.xml 以及 ftl 视图对象以及 tomcat 启动命令

这里写图片描述

前台启动成功…

打开Postman工具，测试请求….

前台:

这里写图片描述

后台 :

这里写图片描述
