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();
    }
}

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);
                }
    }
}

/* * To change this template, choose Tools | Templates * and open the template in the editor. */ 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。
