父工程创建
1.新建一个spring项目
2.选择合适的springboot版本,点击【完成】,即创建父工程完毕
3.删除父工程中无用文件:src
创建子工程模块
1.右键项目名->新建(news)->模块(Module)
2.选择新建Maven工程(注意此处的SDK需与父工程保持一致)
3.填写子工程模块信息(此处组id与父工程保持一致)

测试
1.父工程添加spring web
依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
2.子工程编写启动类及controller类
FastDemoWebApplication
@SpringBootApplication
public class FastDemoWebApplication {
public static void main(String[] args) {
SpringApplication.run(FastDemoWebApplication.class,args);
}
}
HelloController
@Controller
public class HelloController {
@RequestMapping("/hello")
@ResponseBody
public String hello(){
return "hello world!";
}
}
3.运行项目,访问localhost:8080/hello
,能正常输入内容,则表示父子工程无问题
可以在idea右侧页签栏中点击【Maven】查看父子工程结构及其拥有依赖
如果显示如下图
可点击右上角设置图标,点击选择【将模块分组】即可
