这篇文章主要介绍了SpringBoot+Maven 多模块项目的构建、运行、打包实战,小编觉得挺不错的,现在分享给大家,也给大家做个参考。一起跟随小编过来看看吧

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)

        <executions>

          <execution>

            <goals>

      </plugin>

    </plugins>

  </build>

<packaging>jar</packaging>

  

<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:

十三、项目打包命令: mvn clean package 或者 使用右边工具栏的图形化界面打包也可以:

十四、打包成功日志:
