SpringBoot Maven多模块 SpringBoot+Maven 多模块项目的构建、运行、打包实战

zekeTao 人气:0

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:

<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)

<modelVersion>4.0.0</modelVersion>  
  <groupId>com.example</groupId> 
  <artifactId>springboot-multi</artifactId> 
  <version>0.0.1-SNAPSHOT</version> 
  <!-- 此处改为pom --> 
  <packaging>pom</packaging> 
 
  <name>springboot-multi</name> 
  <description>Demo project for Spring Boot</description> 
 
  <modules> 
    <module>web</module> 
    <module>service</module> 
    <module>dao</module> 
    <module>entity</module> 
  </modules> 
 
  <parent> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-starter-parent</artifactId> 
    <version>1.5.10.RELEASE</version> 
    <relativePath/> <!-- lookup parent from repository --> 
  </parent> 
 
  <properties> 
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> 
    <java.version>1.8</java.version> 
  </properties> 
 
  <dependencies> 
    <dependency> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-starter-web</artifactId> 
    </dependency> 
  </dependencies> 
 
  <!--指定使用maven打包--> 
  <build> 
    <plugins> 
      <plugin> 
        <groupId>org.apache.maven.plugins</groupId> 
        <artifactId>maven-compiler-plugin</artifactId> 
        <version>3.1</version> 
        <configuration> 
          <source>${java.version}</source> 
          <target>${java.version}</target> 
        </configuration> 
      </plugin> 
 
      <plugin> 
        <groupId>org.apache.maven.plugins</groupId> 
        <artifactId>maven-surefire-plugin</artifactId> 
        <version>2.19.1</version> 
        <configuration> 
          <skipTests>true</skipTests>  <!--默认关掉单元测试 --> 
        </configuration> 
      </plugin> 
    </plugins> 
  </build> 

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

<modelVersion>4.0.0</modelVersion>  
  <groupId>com.example</groupId> 
  <artifactId>web</artifactId> 
  <version>0.0.1-SNAPSHOT</version> 
  <packaging>jar</packaging> 
 
  <name>web</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> 
 
  <dependencies> 
    <dependency> 
      <groupId>com.example</groupId> 
      <artifactId>service</artifactId> 
      <version>0.0.1-SNAPSHOT</version> 
    </dependency> 
    <dependency> 
      <groupId>com.example</groupId> 
      <artifactId>dao</artifactId> 
      <version>0.0.1-SNAPSHOT</version> 
    </dependency> 
    <dependency> 
      <groupId>com.example</groupId> 
      <artifactId>entity</artifactId> 
      <version>0.0.1-SNAPSHOT</version> 
    </dependency> 
  </dependencies> 
 
  <!--spring boot打包的话需要指定一个唯一的入门--> 
  <build> 
    <plugins> 
      <plugin> 
        <groupId>org.springframework.boot</groupId> 
        <artifactId>spring-boot-maven-plugin</artifactId> 
        <configuration> 
          <!-- 指定该Main Class为全局的唯一入口 --> 
          <mainClass>com.example.WebApplication</mainClass> 
          <layout>ZIP</layout> 
        </configuration> 
        <executions> 
          <execution> 
            <goals> 
              <goal>repackage</goal><!--可以把依赖的包都打包到生成的Jar包中--> 
            </goals> 
          </execution> 
        </executions> 
      </plugin> 
    </plugins> 
  </build> 

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

<modelVersion>4.0.0</modelVersion> 
 
  <groupId>com.example</groupId> 
  <artifactId>service</artifactId> 
  <version>0.0.1-SNAPSHOT</version> 
  <packaging>jar</packaging> 
 
  <name>service</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> 
 
  <dependencies> 
    <dependency> 
      <groupId>com.example</groupId> 
      <artifactId>dao</artifactId> 
      <version>0.0.1-SNAPSHOT</version> 
    </dependency> 
    <dependency> 
      <groupId>com.example</groupId> 
      <artifactId>entity</artifactId> 
      <version>0.0.1-SNAPSHOT</version> 
    </dependency> 
  </dependencies> 

八、dao子模块pom.xml (依赖entity子模块) 

<modelVersion>4.0.0</modelVersion> 
 
<groupId>com.example</groupId> 
<artifactId>dao</artifactId> 
<version>0.0.1-SNAPSHOT</version> 
<packaging>jar</packaging> 
 
<name>dao</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> 
 
<dependencies> 
  <dependency> 
    <groupId>com.example</groupId> 
    <artifactId>entity</artifactId> 
    <version>0.0.1-SNAPSHOT</version> 
  </dependency> 
</dependencies> 

九、entity子模块

<modelVersion>4.0.0</modelVersion> 
 
<groupId>com.example</groupId> 
<artifactId>entity</artifactId> 
<version>0.0.1-SNAPSHOT</version> 
<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:
