Springcloud (10): Implementing declarative rest calls with feign-constructing multi-parameter requests

URL to request multiple parameters

Suppose the requested URL contains multiple parameters, such as: Http://localhost:8086/user1?id=1&username=nihao

1.1. Feign interface

@FeignClient (name =  "Spring-ribbon-eureka-client2") public interface userfeignclient {      @RequestMapping (value =  "/{id}",  method = requestmethod.get)     public user findbyid (@PathVariable ("id")  long id)  throws  exception;    /**get mode, multi-parameter request mode one */     @RequestMapping (value  =  "/find",  method = requestmethod.get)     public user find1 ( @RequestParam ("id")  Long id,  @RequestParam ("username")  string username)  throws  exception;    /**get mode, multi-parameter request mode two */     @RequestMapping (value  =  "/find",  method = requestmethod.get)     public user find2 ( @RequestParam  map<string, object> map)  throws Exception;     /**post mode, multi-parameter request */     @RequestMapping (value =  "/find",  method = requestmethod.post)     public user find3 (@RequestBody  user user)  throws  Exception;}

1.2, using

package com.example.demo.controller;import com.example.demo.feign.userfeignclient;import  com.example.demo.pojo.user;import org.springframework.beans.factory.annotation.autowired;import  org.springframework.web.bind.annotation.*;import java.util.hashmap;import java.util.map;/** *   User controller * *  @Author:  I love big gold  *  @Description:  user controller *   @Date:  create in 11:07 2017/7/10 */@RestControllerpublic  class  usercontroller {     @Autowired     private userfeignclient  userFeignClient;     @GetMapping ("/user/{id}")     public  User findbyid (@PathVariable  long id)  throws Exception {         if  (Null == id)  {             return nuLl;        }        return   this.userfeignclient.findbyid (ID);    }     @GetMapping ("/ User1 ")     public user find1 (User user)  throws exception { &NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;SYSTEM.OUT.PRINTLN ("Get mode, multi-parameter request mode one  : "  +  User);        if  (null == user | |  null == user.getid ())  {             return null;        }         return  this.userfeignclient.find1 (User.getid (),  user.getusername ());     }     @GetMapping ("/user2")     public user find2 ( User user)  throws exceptION&NBSP;{&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;SYSTEM.OUT.PRINTLN ("Get mode, multi-parameter request mode two  : "  + user);        if  (null == user | |  null == user.getid ())  {             return null;        }         Map<String, Object> map = new HashMap<String, Object> ();         map.put ("id",  user.getid ());         return  this.userfeignclient.find2 (map);    }      @PostMapping ("/user3")     public user find3 (User user)  throws exception {        system.out.println ("Post mode, Multi-parameter request mode  :  " + User);        if  (null == user | |  null == user.getid ())  {             return null;        }         return  this.userfeignclient.find3 (user);     }}
