Eclipse创建多模块Spring boot项目

**1****、安装****sts****工具**

打开Eclipse，选择Help -> Eclipse Marketplace…

Search或选择“Popular”标签，搜索spring，选择Spring Tool Suite (STS) for Eclipse插件，安装

**2、new project ，选择spring -> spring starter project**

**根据情况选择Spring boot初始的依赖，刚开始建议只选择web，不然cache，mysql，redis没有配置文件的情况下，运行会报错，点击finish完成**

**3、删除模块中src，target文件，只保留pom文件。**

选中项目点击右键-->Properties-->Resource-->Java Build Path-->Source，删掉失效的src相关的文件，解决红色叹号问题。

**4、修改POM文件，把这个模块作为父模块**

**把packaging的值修改为pom，并****声明子模块**

这里我们使用<dependecyManagement>做maven依赖版本管理，其他子模块则可以直接依赖，不用填写版本。

**4、选中该父模块点击右键-->Maven-->New Maven Module Project，创建子模块。填写子模块名称，点击finish完成。**

以此类推，完成其他子模块的创建

另外，某子模块中如果想用其他模块的类，则在改子模块中引入其他模块依赖，以demo-web为例，我们需要调用demo-iservice的接口，则在demo-web的pom.xml文件中，我们需要引入对demo-iservice的依赖，示例如下：

<dependencies>
       
       <dependency>
          <groupId>com.wangphGit</groupId>
          <artifactId>demo-iservice</artifactId>
       </dependency>
    </dependencies>

所以子项目创建完成之后，项目包结构如下：

最后，需要运行的模块里面，编写springboot引导启动程序，如果仅仅测试多模块是否创建成功，可以只启动demo-web层，直接调用demo-iservice接口。参考示例如下：

实际应用中我们一般启动demo-service-ipml模块和demo-web模块，采用dubbo做分布式部署。关于dubbo整合参见：
