springboot创建步骤

1.定义controller

@RestController
public class HellowController{
@RequestMapping("/hello)
public String hello(){
returen "hello Spring Boot!"
}
}

2.定义启动类

@SpringBootApplication
public class HelloApplication(String[] args){
SpringApplication.run(HelloApplication.class,args)

}

总结:

1.需要编写一个controller类,

需要家注解:类上:@RestController

方法上:@RequestMapping("/hello)

2.需要编写一个应用启动类

需要加注解:@SpringBootApplication

main函数需要一行代码:SpringApplication.run(HelloApplication.class,args)
