SpringBoot+Maven 多模块项目的构建、运行、打包实战

时间:2022-09-03 08:17:36

本篇文章主要介绍了springboot+maven 多模块项目的构建、运行、打包,分享给大家,具体如下:

项目使用的工具:

  1. intellij idea
  2. jdk 1.8
  3. apache-maven-3.3.9

项目的目录:

  1. 主项目 springboot-multi
  2. 子模块 entity、dao、service、web

一、使用idea创建一个springboot项目 : file -> new -> project 项目名称为springboot-multi

二、删除项目中的src目录,把pom.xml中的项目打包方式改为pom,如下:

?
1
2
3
4
5
<groupid>com.example</groupid>
<artifactid>springboot-multi</artifactid>
<version>0.0.1-snapshot</version>
<!-- 此处改为pom -->
<packaging>pom</packaging>

三、创建springboot-multi项目的子模块,在项目上右键单击,选择:new -> module。

四、创建四个子模块后,删除子模块中 src/main/java、src/main/java下的所有文件(如果没有文件跳过此操作),只保留web子模块的springboot的application主启动类。

五、主项目pom.xml (注意<modules>标签是否指定了子模块)

            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

七、service子模块pom.xml(依赖 dao 、entity子模块)

      <artifactid>entity</artifactid>
      <version>0.0.1-snapshot</version>
    </dependency>
  </dependencies>

<name>entity</name>
<description>demo project for spring boot</description>
 
  <parent>
    <groupid>com.example</groupid>
    <artifactid>springboot-multi</artifactid>
    <version>0.0.1-snapshot</version>
    <relativepath>../pom.xml</relativepath>
  </parent>

十、pom.xml文件中需要注意的就是:

  1. 主项目的modules标签指定的子模块是否正确
  2. 子模块之间的依赖
  3. 子模块的parent标签

十一、web子模块的application启动类:

@restcontroller
@springbootapplication
public class webapplication {
 
  public static void main(string[] args) {
    springapplication.run(webapplication.class, args);
  }
 
  @requestmapping(value = "/test",method = requestmethod.get)
  public string test(){
    return "test success";
  }
}

十二、执行main方法启动项目,访问localhost:8080/test,出现如下页面表示项目搭建成功:
