idea方式1:Maven创建
- 首先创建一个Maven的普通项目,不选择模板
- 填入Maven项目的基本信息
- 创建完成后,在pom.xml文件中,添加如下依赖
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.4.4</version> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies>
- 添加成功后,在java目录下创建包,包中创建启动类
package com.gongxy.demo; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class DemoApplication { public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args); } }
- 测试代码
package com.gongxy.demo.controller; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; @RestController public class EmployeeController { @GetMapping("hello") public String hello() { return "hello"; } }
- 访问地址
idea方式2:Spring Initializr
- 创建项目是选择 Spring Initializr,如下图
- 填入Maven项目的基本信息
- 选择需要添加的依赖,如图
- 输入项目信息
- 添加包controller,添加测试类EmployeeController类
package com.gongyg.demo.controller; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; @RestController public class EmployeeController { @GetMapping("hello") public String hello() { return "hello"; } }
- 运行项目,并访问地址
