Maven聚合项目管理(前后端分离管理)

通过Maven项目管理创建前后端分离开发环境。  
1 父项目上一定要有

<modules>
        <module>manager-pojo</module>
        <module>manager-mapper</module>
        <module>manager-service</module>
        <module>manager-web</module>
      </modules>

2 子项目一定要有  
  
manager  
com.zxf  
1.0-SNAPSHOT  
  
如果以上2点没有声明，那么父子自己就无法继承jar包

3 父项目中需要定义统一的版本管理

<properties>
        <junit.version>4.12</junit.version>
        <spring.version>4.1.3.RELEASE</spring.version>
        <mybatis.version>3.2.8</mybatis.version>
        <mybatis.spring.version>1.2.2</mybatis.spring.version>
        <mysql.version>5.1.32</mysql.version>
        <druid.version>1.0.9</druid.version>
        <jstl.version>1.2</jstl.version>
        <servlet.version>2.5</servlet.version>
        <jsp.version>2.0</jsp.version>
        <tomcat.version>2.2</tomcat.version>
      </properties>

<dependencyManagement>
    
          <dependencies>
            <dependency>
              <groupId>junit</groupId>
              <artifactId>junit</artifactId>
              <version>${ junit.version}</version>
            </dependency>
            <dependency>

              <artifactId>spring-test</artifactId>
              <version>${ spring.version}</version>

            </dependency>
            <dependency>
              <groupId>org.mybatis</groupId>

            </dependency>
            <dependency>
              <groupId>com.alibaba</groupId>
              <artifactId>druid</artifactId>
              <version>${ druid.version}</version>
            </dependency>
            
            <dependency>
              <groupId>org.springframework</groupId>
              <artifactId>spring-context</artifactId>
              <version>${ spring.version}</version>

            <dependency>

              <artifactId>spring-beans</artifactId>
              <version>${ spring.version}</version>
            </dependency>
            <dependency>
              <groupId>org.springframework</groupId>
              <artifactId>spring-jdbc</artifactId>
              <version>${ spring.version}</version>
            </dependency>
            <dependency>
              <groupId>org.springframework</groupId>
              <artifactId>spring-webmvc</artifactId>
              <version>${ spring.version}</version>
            </dependency>
            <dependency>
              <groupId>org.springframework</groupId>
              <artifactId>spring-aspects</artifactId>
              <version>${ spring.version}</version>
            </dependency>
            
            <dependency>
              <groupId>jstl</groupId>
              <artifactId>jstl</artifactId>
              <version>${ jstl.version}</version>
            </dependency>
            <dependency>
              <groupId>javax.servlet</groupId>
              <artifactId>servlet-api</artifactId>
              <version>${ servlet.version}</version>
            </dependency>
            <dependency>
              <groupId>javax.servlet</groupId>
              <artifactId>jsp-api</artifactId>
              <version>${ jsp.version}</version>
            </dependency>
    
           </dependencies>
        </dependencyManagement>

其中在父项目中加入了  
  
  
标签表示，子类不能直接引用和继承  
如果在子类中引用，可以这样写

<dependencies>
          <dependency>
              <groupId>com.zxf</groupId>
              <artifactId>manager-pojo</artifactId>
              <version>1.0-SNAPSHOT</version>
          </dependency>
          <dependency>
              <groupId>org.mybatis</groupId>
              <artifactId>mybatis</artifactId>
          </dependency>
          <dependency>
              <groupId>org.mybatis</groupId>
              <artifactId>mybatis-spring</artifactId>
    
          </dependency>
          <dependency>
              <groupId>mysql</groupId>
              <artifactId>mysql-connector-java</artifactId>
    
          </dependency>
          <dependency>
              <groupId>com.alibaba</groupId>
              <artifactId>druid</artifactId>
    
          </dependency>
    
      </dependencies>

记住这里不要写版本号，这样就动态的继承了父项目的JAR包了，父项目可以随意更改版本号，子项目也动态更新了。
