一：pom.xml依赖配置
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</properties>

<dependencies>
<!-- 上边引入 parent，因此 下边无需指定版本 -->
<!-- 包含 mvc,aop 等jar资源 -->
<dependency>

二：SpringbootApplication.java 类

package com.tc.app;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringbootApplication {

public static void main(String[] args) {
        SpringApplication.run(SpringbootApplication.class, args);

}
}
三：TestController.java 类
package com.tc.app;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class TestController {
@GetMapping("/helloworld")
public String helloworld() {
return "helloworld";
}

}

四：访问请求 http://localhost:8080/helloworld
