maven+mybatis+springmvc搭建多模块maven工程(模仿黑马淘淘商城项目)

源代码下载

模仿气象信息收集单位，做一个ssm框架的工程，然后发布webservice

本篇先搭建ssm工程Weather

安装环境

jdk1.7.0_79+Maven 3.5.2+MyEclipse10

1.创建weather-parent

1.1创建Maven Project

如图依次选择

图1.1

图1.2

图1.3

说明:weather-parent为聚合工程，打包方式选择pom。主要用于管理jar文件的版本。之后的Maven Project 需要继承weather-parent。图1.3显示 Project"weather-parent"already exists是因为我已经有一个同名项目，直接点击finish创建完成。进入配置过程。

1.2配置weather-parent

打开项目根目录中的pom.xml。配置常用的jar文件的依赖，并单独剥离版本号统一管理。

pom.xml

2.创建weather-common

2.1  前两步参考图1.1和图1.2

第三步选择打包方式和继承关系如下图：

图2.1

2.2  配置pom.xml

pom.xml

<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><artifactId>weather-parent</artifactId><groupId>com.weather</groupId><version>0.0.1-SNAPSHOT</version></parent><groupId>com.weather</groupId><artifactId>weather-common</artifactId><version>0.0.1-SNAPSHOT</version><!-- 添加依赖 --><dependencies><!-- 时间操作组件 --><dependency><groupId>joda-time</groupId><artifactId>joda-time</artifactId></dependency><!-- Apache工具组件 --><dependency><groupId>org.apache.commons</groupId><artifactId>commons-lang3</artifactId></dependency><dependency><groupId>org.apache.commons</groupId><artifactId>commons-io</artifactId></dependency><dependency><groupId>commons-net</groupId><artifactId>commons-net</artifactId></dependency><!-- Jackson Json处理工具包 --><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId></dependency><!-- httpclient --><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId></dependency><!-- 单元测试 --><dependency><groupId>junit</groupId><artifactId>junit</artifactId></dependency><!-- 日志处理 --><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId></dependency></dependencies></project>

说明：weather-common是用来存放一些通用的工具类以及业务bean(也就是pojo或者vo)

项目建成后结构如下。

图2.2

3.创建weather-manager

3.1前两步参考图1.1和图1.2

第三步

图3.1

3.2配置pom.xml

<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><artifactId>weather-parent</artifactId><groupId>com.weather</groupId><version>0.0.1-SNAPSHOT</version></parent><groupId>com.weather</groupId><artifactId>weather-manager</artifactId><version>0.0.1-SNAPSHOT</version><packaging>pom</packaging><!-- 添加依赖 --><dependencies><dependency><groupId>com.weather</groupId><artifactId>weather-common</artifactId><version>0.0.1-SNAPSHOT</version></dependency></dependencies><!-- 添加tomcat插件 --><build><plugins><plugin><groupId>org.apache.tomcat.maven</groupId><artifactId>tomcat7-maven-plugin</artifactId><configuration><port>8080</port><path>/</path></configuration></plugin></plugins></build></project>

4.为weather-manager创建moudle(模块)

创建模块可以将springmvc中的model,view,controller分开，moudle是project的子工程。

4.1创建moudle，在weather-manager上右键新建maven-moudle

图4.1

图4.2

图4.3

4.2配置pom.xml

<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><artifactId>weather-manager</artifactId><groupId>com.weather</groupId><version>0.0.1-SNAPSHOT</version><relativePath>..</relativePath></parent><artifactId>weather-manager-dao</artifactId><!-- 添加依赖 --><dependencies><dependency><groupId>com.weather</groupId><artifactId>weather-manager-pojo</artifactId><version>0.0.1-SNAPSHOT</version></dependency><!-- Mybatis --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId></dependency><dependency><groupId>com.github.miemiedev</groupId><artifactId>mybatis-paginator</artifactId></dependency><dependency><groupId>com.github.pagehelper</groupId><artifactId>pagehelper</artifactId></dependency><!-- sqlserver --><dependency><groupId>com.microsoft.sqlserver</groupId><artifactId>sqljdbc4</artifactId></dependency><!-- 连接池 --><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId></dependency></dependencies><!-- 如果不添加此节点mybatis的mapper.xml文件都会被漏掉。 --><build><resources><resource><directory>src/main/java</directory><includes><include>**/*.properties</include><include>**/*.xml</include></includes><filtering>false</filtering></resource></resources></build></project>

说明：dao模块存放mybatis的mapper.xml和对应的mapper类，mapper类是数据库的表映射出来的java类

5.参考步骤4创建weather-manager-pojo

该moudle暂时不需要配置pom.xml

6.参考步骤4创建weather-manager-service

pom.xml

<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><artifactId>weather-manager</artifactId><groupId>com.weather</groupId><version>0.0.1-SNAPSHOT</version><relativePath>..</relativePath></parent><artifactId>weather-manager-service</artifactId><dependencies><dependency><groupId>com.weather</groupId><artifactId>weather-manager-dao</artifactId><version>0.0.1-SNAPSHOT</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aspects</artifactId></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId></dependency></dependencies></project>

7.创建weather-manager-web模块

7.1前两步参考weather-manager-dao

第三步

图7.1

打包方式是war包。

7.2.配置pom.xml

<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><artifactId>weather-manager</artifactId><groupId>com.weather</groupId><version>0.0.1-SNAPSHOT</version><relativePath>..</relativePath></parent><artifactId>weather-manager-web</artifactId><packaging>war</packaging><!-- 添加依赖 --><dependencies><dependency><groupId>com.weather</groupId><artifactId>weather-manager-service</artifactId><version>0.0.1-SNAPSHOT</version></dependency><!-- JSP相关 --><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId></dependency><dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><scope>provided</scope></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jsp-api</artifactId><scope>provided</scope></dependency><!-- 文件上传组件 --><dependency><groupId>commons-fileupload</groupId><artifactId>commons-fileupload</artifactId></dependency></dependencies></project>

7.3.配置web.xml

src\main\webapp\WEB-INF\web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"id="ryzh" version="2.5"><display-name>weather-manager</display-name><welcome-file-list><welcome-file>login.jsp</welcome-file></welcome-file-list><!-- 初始化spring容器 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring/applicationContext-*.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><listener><listener-class>org.springframework.web.util.WebAppRootListener</listener-class></listener><!-- 解决post乱码 --><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></filter><filter-mapping><filter-name>CharacterEncodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!-- 登录退出session控制 --><!--<session-config> <session-timeout>10</session-timeout> </session-config> --><!-- springmvc的前端控制器 --><servlet><servlet-name>weather-manager</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!-- contextConfigLocation不是必须的， 如果不配置contextConfigLocation， springmvc的配置文件默认在：WEB-INF/servlet的name+"-servlet.xml" --><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring/springmvc.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>weather-manager</servlet-name><url-pattern>/</url-pattern></servlet-mapping></web-app>

至此，整个项目创建完成。下面进行ssm框架整合。

整合框架前查看manager项目的pom.xml文件。多出了六行内容。

<modules><module>weather-manager-pojo</module><module>weather-manager-dao</module><module>weather-manager-service</module><module>weather-manager-web</module></modules>

这些内容是创建moudle时自动添加到pom.xml文件中的。但是该配置内容不会自动删除。

如果创建好的moudle有错误需要删除，那么，manager的pom文件中，这些moudle配置需要手动来删除，否则运行项目会报错。

8.整合ssm框架。

所有的web端的文件都存放在
weather-manager-web\src\main\webapp

weather-manager-web中需要一些配置文件才能与其他的moudle产生联系。这些配置文件主要包括mybatis的和spring的。

下面直接贴出来配置文件的目录以及内容。

图8.1

SqlMapConfig.xml

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration><settings><!-- 打印查询语句 --><setting name="logImpl" value="STDOUT_LOGGING" /><!--解决，查询返回结果含null没有对应字段值问题 --><setting name="callSettersOnNulls" value="true" /></settings></configuration>

jdbc.properties

我用的是sqlserver。不是太常见。创建的mysql配置很好找。

jdbc.driver=com.microsoft.sqlserver.jdbc.SQLServerDriver

#数据库的url和名称(master)jdbc.url=jdbc:sqlserver://localhost:1433;DatabaseName=masterjdbc.username=sajdbc.password=123456#定义初始连接数initialSize=0#定义最大连接数maxActive=20#定义最大空闲maxIdle=20#定义最小空闲minIdle=1#定义最长等待时间maxWait=60000

9.测试

测试：

先右击weather-parent和weather-common右击--run as--maven install

然后weather-manager 右击--run as--maven build(第一次maven build需要命令clean tomcat7:run)
