springboot项目切分多个module_我是坑货_springboot 多module

未知 02-07 5519

实际上我们的项目肯定不是，初始化一个springboot项目就完事了，我们可能要分成一个个子模块，互相依赖的情况。中间有的模块就是提供DAO这些基础，有的是提供API接口服务的，有的则是独立的给APP或者web端接口的。

如何去划分模块：（1）创建项目创建一个maven项目，作为总的依赖，要把src里面都删除，仅仅留下来个POM文件作为root和一个说明文档就可以了。

（2）先建一个module 这里创建module跟创建maven工程一样，我们新建的项目路径都尽量统一，比如：

module1 com.zp.xxx.core module2 com.zp.xxx.api module3 com.zp.xxx.app

(3）整理pom文件第一步是project的pom文件添加modules标签

<modules> <module>coupon-template-serv</module> <module>coupon-template-api</module> <module>coupon-template-dao</module> </modules>

打包方式修改成pom

mudule的pom文件修改，将之前生成的groupid那一块修改成这个样子

<modelVersion>4.0.0</modelVersion> <parent> <groupId>com.zp.springboot</groupId> <artifactId>coupon</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <artifactId>coupon-template-serv</artifactId> <packaging>jar</packaging>

PS中间会有pom文件在idea里面变橘黄的情况，实际上点击pom文件田间maven工程就可以。

如果设置好，在idea侧边栏的maven里面会自动识别那个是root文件；

示例： project pom
