【Maven】分模块开发创建项目_maven分模块-优快云博客

本文链接：https://blog.youkuaiyun.com/lklalmq/article/details/145293616

这里简单演示springboot vue项目后端的分模块是怎么分的

创建父工程

‘

删除无用目录文件

修改父pom

添加如下

  <properties>
    <maven.compiler.source>8</maven.compiler.source>
    <maven.compiler.target>8</maven.compiler.target>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
  </properties>

  <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.7.3</version>
  </parent>

创建子模块

创建子模块的具体用途还要看自己情况，不用完全跟我一样

依赖模块

仅用于定义 Maven 项目的结构和依赖关系。
不包含任何 Java 代码，也不产生任何可执行文件。
主要用于聚合其他模块，管理依赖和配置。
适用于作为其他模块的父模块或者聚合模块。

这个pom文件的关键在于<dependencyManager>
dependencyManagement只是声明依赖，并不实现引入，因此子项目需要显示的声明需要用的依赖。

主模块

项目启动入口的模块

图中要选Maven的，不是Gradle

继承依赖标签，并引入必要依赖

写个Controller测试

@RestController
@RequestMapping("/test")
public class TestController {
    @GetMapping
    public String test(){
        return "hello world";
    }
}

测试

实体类模块

这些模块都是跟依赖模块一样的方式创建，根据自己的需要
