• SpringBoot+Maven 多模块项目的构建、运行、打包


    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:
