SpringBoot+Maven 多模块项目的构建、运行、打包实战
作者:zekeTao
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:
- IntelliJ IDEA
- JDK 1.8
- apache-maven-3.3.9
项目的目录:
- 主项目 springboot-multi
- 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:
- 主项目的modules标签指定的子模块是否正确
- 子模块之间的依赖
- 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:
