新建controller

@SpringBootApplication

@ComponentScan(basePackages = "controller")

//@EnableAutoConfiguration

@RestController

public class App {

@RequestMapping("hello1")

Object get() {

return "hello1";

}

public static void main(String[] args) {

SpringApplication.run(App.class, args);

}

}

 

注意:

@EnableAutoConfiguration:

这个注解告诉Spring Boot根据添加的jar依赖猜测你想如何配置Spring。 由于spring-boot-starter-web添加了Tomcat和Spring MVC 所以auto-configuration将假定你正在开发一个web应用并相应地对Spring进行设置。
