</project>

启动controller

小结：

2、聚合

问题：一个模块更新，其他模块不知道，可能出现冲突，导致项目无法启动

解决：用一个模块统一管理

作用:聚合用于快速构建maven工程，一次性构建多个项目/模块。

1、建立一个空项目

2、配置pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<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.itheima</groupId>
    <artifactId>ssm</artifactId>
    <version>1.0-SNAPSHOT</version>

    <!--定义改工程用于进行构建管理-->
    <packaging>pom</packaging>

    <!--管理的工程列表-->
    <modules>
        <!--具体名称-->
        <module>../ssm_pojo</module>
        <module>../ssm_dao</module>
        <module>../ssm_service</module>
        <module>../ssm_controller</module>
    </modules>
</project>

注意事项:参与聚合操作的模块最终执行顺序与模块间的依赖关系有关，与配置顺序无关

3、继承

作用:通过继承可以实现在子工程中沿用父工程中的配置 作用:通过继承可以实现在子工程中沿用父工程中的配置

问题：依赖的资源可能会出现冲突

（ssm）pom

（ssm_pojo）pom

（ssm_dao）pom：可以去除依赖版本

4、属性

定义一个变量，统一配置

1、自定义属性

 

2、内置属性

3、Setting属性

4、java系统属性

5、环境变量属性
