Rest Webservice 環境搭建流程和例項

1 pojo

package com.train.pojo;

 

public classRestResponse {

   /**

     * 返回碼

     */

   privateintresponseCode;

   

   /**

     * 資料

     */

   privateObject data;

   

   /**

     * 簡介

     */

   privateString Message;

   

   publicintgetResponseCode() {

        return responseCode;

   }

   

   publicvoidsetResponseCode(intresponseCode) {

        this.responseCode = responseCode;

   }

   

   publicObject getData() {

        return data;

   }

   

   publicvoidsetData(Object data) {

        this.data = data;

   }

   

   publicString getMessage() {

        return Message;

   }

   

   publicvoidsetMessage(String message) {

        Message = message;

   }

   @Override

   publicString toString() {

        return "RestResponse [responseCode="+ responseCode+ ", data="+ data

            + ", Message=" + Message + "]";

   }

}

1               client

 

package com.train.controller;

 

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.client.RestTemplate;

 

import com.train.pojo.RestResponse;

 

@Controller

@RequestMapping("/send")

public classSendToServiceController {

   

   protectedRestTemplate restTemplate= newRestTemplate();

   

   @RequestMapping("/get")

   publicvoidgetTest() {

        String path="http://localhost:8080/train_010_spring_springmvc_rest_webservice/hello/get?value={value}";

        String p1="getname";

       

        RestResponse response = restTemplate.getForObject(path,RestResponse.class,p1);

        System.out.println(response.getResponseCode());

        System.out.println(response.getData());

   }

   

   @RequestMapping("/post")

   publicvoidpostTest() {

        //類似，網上例子多

   }

}

2               service

 

package com.train.web.v1.controller;

 

import javax.servlet.http.HttpServletRequest;

 

import org.springframework.stereotype.Controller;

import org.springframework.ui.Model;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.ResponseBody;

 

import com.train.pojo.RestResponse;

 

@Controller

@RequestMapping("/hello")

public classHelloWebServiceController {

   

   

   @RequestMapping("/get")

   @ResponseBody

   publicRestResponse getTest(HttpServletRequest request,Model model){

        String data = "";

        Object value = request.getParameter("value");

        if(value!=null &&value.toString().equals("getname")){

            data= "大家好";

        }

        RestResponse response = new RestResponse();

        if(!data.equals("")){

            response.setResponseCode(0);

            response.setMessage("SUCCESS");

        }

        else {

            response.setResponseCode(999);

            response.setMessage("Error occured");

        }

        response.setData(data);

        return response;

   }

   @RequestMapping("/post")

   publicvoidpostTest(){

       

   }

}

 

3               環境搭建，就是普通的spring 環境另外加上兩個jar包

jackson-core-asl-1.9.13  jackson-mapper-asl-1.9.13
