java web HttpClient 开发一个接口

项目是基于SpringMvc的，最近项目中需要给另一个项目开放一个http接口供别人调数据  所以写了这么一个例子供新手参考

Controller:

package com.cicro.iris.web.infomanage;

import javax.annotation.Resource;

import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;

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

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

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

import com.cicro.iris.service.infomanage.ArticleListToJsonService;

import com.cicro.iris.util.CacheManager;

/**

 * @since JDK1.7

 */

@Controller

@RequestMapping(value="/sys/infomanage/ArticleListToJson")

public class ArticleListToJsonController{

    

    

    @Resource

    ArticleListToJsonService articleListToJsonService;

    

    @RequestMapping(value="getJson")

    @ResponseBody

    public String getJson(@RequestParam(value="myy_code")String myy_code,HttpServletRequest request) {

        if(CacheManager.hasCache(myy_code)) {

           return CacheManager.getCache(myy_code);

        }

        else

        {

           CacheManager.putCache(myy_code,articleListToJsonService.getJson(myy_code));

           return articleListToJsonService.getJson(myy_code);

           

        }

    }

}

Client:

package com.cicro.iris.util;

import java.util.ArrayList;

import java.util.List;

import org.apache.http.HttpResponse;

import org.apache.http.NameValuePair;

import org.apache.http.client.HttpClient;

import org.apache.http.client.entity.UrlEncodedFormEntity;

import org.apache.http.client.methods.HttpPost;

import org.apache.http.impl.client.DefaultHttpClient;

import org.apache.http.message.BasicNameValuePair;

import org.apache.http.util.EntityUtils;

          namevaluepairs.add(new BasicNameValuePair("myy_code","ZTFL-001-ZT001-LM001"));

      }catch(Exception e) {

          e.printStackTrace();
