在通过HttpClient或URL方式请求数据的过程中，难免会出现乱码的问题，笔者在项目开发过程中就遇到了此问题，在网上找了一堆资料，都是在接收端解决问题，忽略了发送端的编码问题，所以在接收端所有办法都用了还是不行，现在把解决的办法贴出业，希望能帮助到遇见相同问题的朋友。直接上代码

一、接收端

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.UnsupportedEncodingException;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.ParseException;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import org.json.JSONException;
import org.json.JSONObject;

public static JSONObject post(String url)
   {
       HttpClient httpClient = new DefaultHttpClient();
       HttpPost httpPost = new HttpPost(url);
       httpPost.setHeader("Content-Type","application/x-www-form-urlencoded");


        try {

           HttpResponse httpResponse = httpClient.execute(httpPost);
            InputStream inStream =     httpResponse.getEntity().getContent();
            BufferedReader reader = new BufferedReader(new InputStreamReader(inStream,"utf-8")); //请注意这里的编码
            StringBuilder strber = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null)
                strber.append(line );
            inStream.close();
            JSONObject jsonObj = new JSONObject(strber.toString());
           return jsonObj;
       } catch (Exception e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
           //return null;
       }
       return null;
   }

二、发送端

这里用的是springMVC

import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RequestMapping("/userInfo")
public HttpEntity userInfo(HttpServletRequest request){

            String js = "这是放的是要发送的html文本";
            HttpHeaders headers = new HttpHeaders();
            MediaType mediaType = new MediaType("text","html",Charset.forName("utf-8"));
            headers.setContentType(mediaType);
            return new ResponseEntity<String>(js,headers, HttpStatus.OK);

}
