SpringBoot+Maven 多模块项目的构建、运行、打包实战

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:
