spring-boot-starter-web
:包含了 spring-boot-starter
还自动帮我们开启了 Web 支持我们创建一个 Controller 来演示一下 Spring Boot 的神奇功能
package com.funtl.hello.spring.boot.controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController //alt+enter键导入
public class HelloController {
@GetMapping(value = "/")
public String sayHi() {
return "Hello Spring Boot.";
}
}
启动 HelloSpringBootApplication
的 main()
方法,浏览器访问 http://localhost:8080 可以看到:
Hello Spring Boot.
