1. 继承 Spring Boot 我的项目
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.7.2</version>
<relativePath/>
</parent>
2. 引入 Spring MVC 依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
3. 编写 Controller 代码
@RestController
public class HelloWorldController {@GetMapping("/hello")
public String hello(@RequestParam(value = "name", defaultValue = "World") String name) {return String.format("Hello %s!", name);
}
}
4. 编写启动类
@SpringBootApplication
public class HelloWorldApplication {public static void main(String[] args) {SpringApplication.run(HelloWorldApplication.class, args);
}
}
5. 运行启动类
运行启动类,在浏览器中输出:http://localhost:8080/hello?name= 小穆
,即可看到如下成果:
