比如在浏览器输入http://localhost:8078/hello/helloword访问的是后端的
            
            
              java
              
              
            
          
          @RestController
@RequestMapping("/hello")
public class HelloWord {
    @RequestMapping("/helloword")
    public String helloWord(){
        return  "hello word";
    }
}浏览器将会返回
