HttpClient中文乱码问题

服务端Servlet代码：

package com.httpclient.test;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class HttpClientServlet extends HttpServlet {

	@Override
	protected void doGet(HttpServletRequest req, HttpServletResponse resp)
			throws ServletException, IOException {
		this.doGet(req, resp);
	}

	@Override
	protected void doPost(HttpServletRequest req, HttpServletResponse resp)
			throws ServletException, IOException {
		req.setCharacterEncoding("UTF-8");
		resp.setCharacterEncoding("GBK");
		String username = req.getParameter("username");
		String password = req.getParameter("password");
		System.out.println(username);
		PrintWriter writer = resp.getWriter();
		writer.print(username + " = " + password);
		writer.close();
	}
}

 

HttpClient客户端代码：

package com.chinapay.client;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpStatus;
import org.apache.commons.httpclient.NameValuePair;
import org.apache.commons.httpclient.methods.PostMethod;
import org.apache.commons.httpclient.params.HttpMethodParams;

public class HttpClientPost {

    public static void main(String[] args) throws IOException{
        HttpClient client = new HttpClient();
        client.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "UTF-8");
        String url = "http://localhost:8080/httpclient/HttpClientServlet";
        PostMethod postMethod = new PostMethod(url);

        NameValuePair[] data = {
                new NameValuePair("username", "你好")
                ,new NameValuePair("password", "wangtao") };

        postMethod.setRequestBody(data);
        int resultCode = client.executeMethod(postMethod);
        if(resultCode != HttpStatus.SC_OK){
            System.err.println("Method failed:" + postMethod.getStatusLine());
        }
        InputStream responseBody = postMethod.getResponseBodyAsStream();
                BufferedReader reader = new BufferedReader(new InputStreamReader(responseBody,"GBK"));
                String tempBf = null;
                while((tempBf=reader.readLine()) != null){
                    System.out.println(tempBf);
                }
    }
}

 client.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "UTF-8");和req.setCharacterEncoding("UTF-8");编码格式相同，BufferedReader reader = new BufferedReader(new InputStreamReader(responseBody,"GBK"));和resp.setCharacterEncoding("GBK");的编码格式相同。这样就可以解决乱码问题了。
