**controller层**

**同名hello-service应用1**

@RestController
    public class HelloController {
    
        @RequestMapping("/hello")
        public String hello(){
            return "hello world";
        }
    }

**同名hello-service应用2**

@RestController
    public class HelloController {
    
        @RequestMapping("/hello")
        public String hello(){
            return "hello world2";
        }
