超链接传值中文乱码解决方案.docx

在web开发中，中文乱码问题，我们经常碰到，尤其是超链接和jquery传输中文到后台的action或者servlet，中文就会变成乱码，影响程序的正常执行。 这里给出一个解决方法，个人觉得不错，分享一下： 1、首先创建一个java类，这里给出它的代码，作用是将中文与英文加字符串的转换： package .util;/* * JavaScript escape/unescape 编码的 Java 实现 * author jackyz * keep this copyright info while using this method by free */ public class Escape private final static String hex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private final static byte val = 0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F, 0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F, 0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F, 0x00,0x01,0x02,0x03,0x04,0x05,0x06,0x07,0x08,0x09,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F, 0x3F,0x0A,0x0B,0x0C,0x0D,0x0E,0x0F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F, 0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F, 0x3F,0x0A,0x0B,0x0C,0x0D,0x0E,0x0F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F, 0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F, 0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F, 0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F, 0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F, 0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F, 0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F, 0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F, 0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F, 0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F,0x3F ; public static String escape(String s) StringBuffer sbuf = new StringBuffer(); int len = s.length(); for (int i = 0; i len; i+) int ch = s.charAt(i); if (ch = ) / space : map to + sbuf.append(+); else if (A = ch & ch = Z) / A.Z : as it was sbuf.append(char)ch); else if (a = ch & ch = z) / a.z : as it was sbuf.append(char)ch); else if (0 = ch & ch = 9) / 0.9 : as it was sbuf.append(char)ch); else if (ch = - | ch = _ / unreserved : as it was | ch = . | ch = ! | ch = | ch = * | ch = / | ch = ( | ch = ) sbuf.append(char)ch); else if (ch 8); sbuf.append(hex(0x00FF & ch); return sbuf.toString(); public static String unescape(String s) StringBuffer sbuf = new StringBuffer(); int i = 0; int len = s.length(); while (i len) int ch = s.charAt(i); if (ch = +) / + : map to sbuf.append( ); else if (A = ch & ch = Z) / A.Z : as it was sbuf.append(char)ch); else if (a = ch & ch = z) / a.z : as it was sbuf.append(char)ch); else if (0 = ch & ch = 9) / 0.9 : as it was sbuf.append(char)ch); else if (ch = - | ch = _ / unreserved : as it was | ch = . | ch = ! | ch = | ch = * | ch = / | ch = ( | ch = ) sbuf.append(char)ch); else if (ch = %) int cint = 0; if (u != s.charAt(i+1) / %XX : map to ascii(XX) cint = (cint 4) | vals.charAt(i+1); cint = (cint 4) | vals.charAt(i+2); i+=2; else / %uXXXX : map to unicode(XXXX) cint = (cint 4) | vals.charAt(i+2); cint = (cint 4) | vals.charAt(i+3); cint = (cint 4) | vals.charAt(i+4); cint = (cint 4) | vals.charAt(i+5); i+=5; sbuf.append(char)cint); i+; return sbuf.toString(); 2、在jsp中引入Escape.java文件：代码如下： 在js或jquery中声明并运用中文转换Escape类，代码如下：script type=text/javascript src=testJs/jquery-1.4.3.min.js function init() alert(start js ajax); var url=/chinese; var para1=中文测试1; var para2=测试中文2; var args=data1:escape(para1),data2:para2; $.post(url,args,function(data) if(data) alert(123); ); 3、调用init（） js方法，代码如下：4、创建jquery中调用的servlet类chinese，其在web.xml中的配置如下： chinese .servlet.chinese chinese /chinese 5、完成chinese.java的servlet类，代码如下：package .servlet;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;import .util.Escape;public class chinese extends HttpServlet public void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException response.setContentType(text/html);PrintWriter out = response.getWriter();/request.setCharacterEncoding(utf-8);/response.setCharacterEncoding(utf-8);Escape escape=new Escape();System.out.println(request.getParameter(data1);SuppressWarnings(static-access)String da1=escape.unescape(request.getParameter(data1);String da2=request.getParameter(data2);System.out.println(转换数据：+da1+t未转化：+da2);out.flush();out.close();public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException this.doGet(request, response);6、为了方便转换测试，请不要在servlet里边进行字符集配置，上边方便验证特意注释掉了字符集编码。7、启动项目测试，结果如
