SSM整合的一些配置(基于Maven工程,逆向工程，Restful风格)

自己在学习SSM过程中，一直没有整理过关于如何整个整合配置的，这次基于Maven的SSM配置整理一遍。

1.首先，创建一个Maven工程。在创建Maven工程开始时，一定要把圈住的对号打上，要不可能会出现错误。

2.之后会Next，会出现如下，Group Id和Artifact Id就是Maven的pom.XML配置文件的坐标。其中Artifact Id也是工程的名字，Version选择默认的就可以。Packaging选择war形式的，因为war形式的创建出来的工程才是web工程.其他的不需要填就可以.

3. ①在创建Maven之后可能在pom.xml文件中出现小红叉，有两处要修改。第一处，右键工程--->Maven--->Update Project，之后打上对号。之后等一会就可以了。

②这是可能pom.xml文件还会有小红叉，这是需要创建web需要的一些配置。右键工程--->properties.这时Dynamic Web Module是勾选的，把勾选的勾掉，点击Apply，别点Ok，再把Dynamic Web Module勾选。这是下面会有选项，点击.

③之后就是web的一些配置要放的位置，把这些配置放到相对应的位置就可以了。

4.之后Maven工程就创建完成。来看一下工程结构。src/main/java写源代码的目录，src/main/resource放配置文件的地方，web的一些配置就放在了src/main/webapp下了

5.web.xml配置

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"      xsi:schemaLocation="http://java.sun.com/xml/ns/javaee       http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"><!-- Spring配置 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></context-param><!-- Bootstraps the root web application context before servlet initialization --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!--springMvc配置  --><servlet><servlet-name>springDispatcherServlet</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springmvc.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><!-- Map all requests to the DispatcherServlet for handling --><servlet-mapping><servlet-name>springDispatcherServlet</servlet-name><url-pattern>/</url-pattern></servlet-mapping><!-- 配置字符编码过滤器,此Filter要放在第一个位置上 --><filter><filter-name>characterEncodingFilter</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><init-param><param-name>forceRequestEncoding</param-name><param-value>true</param-value></init-param><init-param><param-name>forceResponseEncoding</param-name><param-value>true</param-value></init-param></filter><filter-mapping><filter-name>characterEncodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!-- 配置REST风格的URL,配置过滤器 --><filter><filter-name>HiddenHttpMethodFilter</filter-name><filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class></filter><filter-mapping><filter-name>HiddenHttpMethodFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!-- 在ajax中，type类型为PUT或者DELETE时，可以直接发送 --><filter><filter-name>HttpPutFormContentFilter</filter-name><filter-class>org.springframework.web.filter.HttpPutFormContentFilter</filter-class></filter><filter-mapping><filter-name>HttpPutFormContentFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping></web-app>

6.spring的applicationContext.xml的配置文件

<?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:mvc="http://www.springframework.org/schema/mvc"xmlns:mybatis-spring="http://mybatis.org/schema/mybatis-spring"xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsdhttp://mybatis.org/schema/mybatis-spring http://mybatis.org/schema/mybatis-spring-1.2.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd"><!-- 除了Controller,其他的都扫描 --><context:component-scan base-package="com.an.crud"><context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/></context:component-scan><context:property-placeholder location="classpath:db.properties"/><!-- 配置数据源 --><bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"><property name="user" value="${jdbc.username}"></property><property name="password" value="${jdbc.password}"></property><property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property><property name="driverClass" value="${jdbc.driverClass}"></property></bean><!-- 配置mybatis --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><!-- mybatis-config配置 --><property name="configLocation" value="classpath:mybatis-config.xml"></property><!-- mybatis的一些mapper --><property name="mapperLocations" value="classpath:mapper/*.xml"></property><!-- 数据源 --><property name="dataSource" ref="dataSource"></property></bean><!-- 配置扫描的接口 --><mybatis-spring:scan base-package="com.an.crud.mapper"/><!-- 配置事务,基于xml声明式事务的配置 --><bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource"></property></bean><aop:config><aop:pointcut expression="execution(* com.an.crud.service..*(..))" id="txPoint"/><!-- 增强事务 --><aop:advisor advice-ref="txAdvice" pointcut-ref="txPoint"/></aop:config><tx:advice id="txAdvice" transaction-manager="transactionManager"><tx:attributes><tx:method name="*"/><tx:method name="get*" read-only="true"/></tx:attributes></tx:advice></beans>

7.Springmvc的配置

<?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:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd"><!-- 只扫描Controller --><context:component-scan base-package="com.an.crud" use-default-filters="false"><context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/></context:component-scan><!-- 视图解析器 --><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/pages/"></property><property name="suffix" value=".jsp"></property></bean><!-- 处理静态资源 --><mvc:default-servlet-handler/><!-- 这个一般都要配,必配 --><mvc:annotation-driven /></beans>

8.mybatis-config配置

<?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><!-- 设置驼峰命名法 --><setting name="mapUnderscoreToCamelCase" value="true"/></settings>  <!-- 别名 --> <typeAliases><package name="com.an.crud.bean"/></typeAliases><!-- 分页插件 --><plugins><plugin interceptor="com.github.pagehelper.PageInterceptor"><!-- 分页参数合理化 --><property name="reasonable" value="true"/></plugin></plugins></configuration>

9.Maven中pom.xml中的依赖

<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>  <groupId>com.an</groupId>  <artifactId>ssm-crud2</artifactId>  <version>0.0.1-SNAPSHOT</version>  <packaging>war</packaging>  <dependencies>  <!--引入项目依赖的jar包 --><!-- SpringMVC、Spring --><!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc --><!--引入pageHelper分页插件 --><dependency><groupId>com.github.pagehelper</groupId><artifactId>pagehelper</artifactId><version>5.0.0</version></dependency><!-- MBG --><!-- https://mvnrepository.com/artifact/org.mybatis.generator/mybatis-generator-core --><dependency><groupId>org.mybatis.generator</groupId><artifactId>mybatis-generator-core</artifactId><version>1.3.5</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>4.3.7.RELEASE</version></dependency><!-- 返回json字符串的支持 --><!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind --><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>2.8.8</version></dependency><!--JSR303数据校验支持；tomcat7及以上的服务器， tomcat7以下的服务器：el表达式。额外给服务器的lib包中替换新的标准的el--><!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-validator --><dependency><groupId>org.hibernate</groupId><artifactId>hibernate-validator</artifactId><version>5.4.1.Final</version></dependency><!-- Spring-Jdbc --><!-- https://mvnrepository.com/artifact/org.springframework/spring-jdbc --><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>4.3.7.RELEASE</version></dependency><!--Spring-test --><!-- https://mvnrepository.com/artifact/org.springframework/spring-test --><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>4.3.7.RELEASE</version></dependency><!-- Spring面向切面编程 --><!-- https://mvnrepository.com/artifact/org.springframework/spring-aspects --><dependency><groupId>org.springframework</groupId><artifactId>spring-aspects</artifactId><version>4.3.7.RELEASE</version></dependency><!--MyBatis --><!-- https://mvnrepository.com/artifact/org.mybatis/mybatis --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.4.2</version></dependency><!-- MyBatis整合Spring的适配包 --><!-- https://mvnrepository.com/artifact/org.mybatis/mybatis-spring --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>1.3.1</version></dependency><!-- 数据库连接池、驱动 --><!-- https://mvnrepository.com/artifact/c3p0/c3p0 --><dependency><groupId>c3p0</groupId><artifactId>c3p0</artifactId><version>0.9.1</version></dependency><!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.41</version></dependency><!-- （jstl，servlet-api，junit） --><!-- https://mvnrepository.com/artifact/jstl/jstl --><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency><!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api --><dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId><version>3.0.1</version><scope>provided</scope></dependency><!-- junit --><!-- https://mvnrepository.com/artifact/junit/junit --><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version></dependency>  </dependencies>  </project>

10.逆向工程的mbg.xml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"><generatorConfiguration>  <context id="DB2Tables" targetRuntime="MyBatis3">    <!-- 配置生成的文件都没有注释 -->  <commentGenerator>  <property name="suppressAllComments" value="true" />  </commentGenerator>  <!-- 配置数据源 -->    <jdbcConnection driverClass="com.mysql.jdbc.Driver"        connectionURL="jdbc:mysql:///ssm_crud"        userId="root"        password="1234">    </jdbcConnection>    <javaTypeResolver>      <property name="forceBigDecimals" value="false" />    </javaTypeResolver><!-- 配置javaBean生成的位置-->    <javaModelGenerator targetPackage="com.an.crud.bean" targetProject=".\src\main\java">      <property name="enableSubPackages" value="true" />      <property name="trimStrings" value="true" />    </javaModelGenerator><!-- 配置sql映射文件生成的位置mapper -->    <sqlMapGenerator targetPackage="mapper"  targetProject=".\src\main\resources">      <property name="enableSubPackages" value="true" />    </sqlMapGenerator><!-- 配置指定mapper接口生成的位置 -->    <javaClientGenerator type="XMLMAPPER" targetPackage="com.an.crud.mapper"  targetProject=".\src\main\java">      <property name="enableSubPackages" value="true" />    </javaClientGenerator><!-- table指定每个表的生成策略 --><!-- tableName:对应的表      domainObjectName:生成的bean实例对象 -->    <table tableName="tb_emp" domainObjectName="Employee"></table><table tableName="tb_dept" domainObjectName="Department"></table>  </context></generatorConfiguration>

11.生成逆向工程的测试：

package com.an.crud.test;import java.io.File;import java.util.ArrayList;import java.util.List;import org.junit.Test;import org.mybatis.generator.api.MyBatisGenerator;import org.mybatis.generator.config.Configuration;import org.mybatis.generator.config.xml.ConfigurationParser;import org.mybatis.generator.internal.DefaultShellCallback;public class TestMBG {@Testpublic void test1() throws Exception{   List<String> warnings = new ArrayList<String>();   boolean overwrite = true;   File configFile = new File("mbg.xml");   ConfigurationParser cp = new ConfigurationParser(warnings);   Configuration config = cp.parseConfiguration(configFile);   DefaultShellCallback callback = new DefaultShellCallback(overwrite);   MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);   myBatisGenerator.generate(null);}}

运行逆向工程的测试，就会生成相对应的bean、mapper等等...，目录结构如下

至此，配置基本完成了，这个简单的CRUD应用用到了BootStrap，大体是这样的，只能实现简单的增删该查，首页使用ajax实现数据交互的.

大体就这样....
