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:
