IDEA创建Springboot多模块项目
IDEA创建Springboot多模块项目
一、创建父模块
File --> New --> Project ,选择 “ Spring Initalizr ” ,点击 Next
Next
Next --> Finish
二、创建子模块
右键根目录,New --> Module
选择 “ Spring Initializr ”,点击Next
此处注意Type选择Maven,Artifact根据自己的分模块的标准进行命名,可以按功能分模块(比如:订单、支付、登陆等模块分,就可以命名为order、pay、login等),此处我按照公共模块,业务模块、工具模块等模块进行划分的。
Next
Next --> Finish
重复上述步骤,根据自身需要再创建其他子模块
三、修改pom文件
子模块
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.7.5</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<groupId>com.hng</groupId>
<artifactId>business</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>business</name>
<description>业务模块</description>
<properties>
<java.version>8</java.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>

</plugins>
</build>
</project>
父模块
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.hng</groupId>
<artifactId>server</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>server</name>
<description>父模块</description>
<packaging>pom</packaging>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.7.5</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<properties>
<java.version>8</java.version>
</properties>
<!--引入子模块-->
<modules>
<module>common</module>
<module>business</module>
<module>system</module>
<module>tools</module>
</modules>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
四、删除多余不必要的文件及目录
1.删除所有子模块的 mvnw、mvnw.cmd、xxx.iml 文件及 .mvn 文件夹
2.删除所有子模块resources文件夹
3.删除所有子模块的的启动类
五、在主模块中添加测试代码,启动项目测试
在主模块business中创建对应的包controller、service等,在controller创建测试代码
package com.hng.business.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* @Author 郝南过
* @Date 2023/11/3 12:21
* @Version 1.0
*/
@RestController
public class TestController {
@RequestMapping("/test")
public String hello(){
return "Hello";
}
}
使用主模块business的启动文件启动项目,访问localhost:8080/test,可以正常看到响应(默认端口为8080,如需要修改可在主模块business下的resources下的application.properties文件中进行配置修改)
