ajax <script type="text/javascript"> function findsc(){ $(‘#metable‘).empty(); $.ajax({ url: "find", type: "get", data:{ key:$(‘#keywords‘).val() }, success:function(data){ alert(data); $(‘#metable‘).append(data); } }); } </script> //servlet关键 protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub response.setContentType("text/html;charset=utf-8"); response. setCharacterEncoding("UTF-8"); response.getWriter().append("Served at: ").append(request.getContextPath()); MyServiceDao myServiceDao=new MyServiceDao(); List<Sc> temp; PrintWriter outme=response.getWriter(); outme.print("<tr><td style=‘background:#FFF68F;‘>学号</td><td style=‘background:#FFF68F;‘>姓名</td><td style=‘background:#FFF68F;‘>语文</td><td style=‘background:#FFF68F;‘>数学</td><td style=‘background:#FFF68F;‘>英语</td><tr>"); try { temp=myServiceDao.getScByName(request.getParameter("key")); for(Sc sc : temp){ outme.print( "<tr><td style=‘background:#CAFF70;‘>"+sc.getId() +"</td><td style=‘background:#CAFF70;‘>"+sc.getName() +"</td><td style=‘background:#CAFF70;‘>"+sc.getYuwen() +"</td><td style=‘background:#CAFF70;‘>"+sc.getShuxue() +"</td><td style=‘background:#CAFF70;‘>"+sc.getYingyu() +"</td><tr>" ); } } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } outme.close(); }

我用*解决了这个问题
web.xml里面的配置

<filter>
<filter-name>SubmitFilter</filter-name>
<filter-class>common.SubmitFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>SubmitFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
*文件里面的代码:
package common;

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class SubmitFilter implements Filter{

private FilterConfig filterConfig = null;
@Override
public void destroy() {

}

@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
if(this.filterConfig == null){
return;
}
HttpServletRequest request = (HttpServletRequest)servletRequest;
HttpServletResponse response = (HttpServletResponse)servletResponse;
//HttpSession session = request.getSession();
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");
response.setContentType("text/html; charset=UTF-8");
filterChain.doFilter(servletRequest, servletResponse);
}

@Override
public void init(FilterConfig arg0) throws ServletException {
this.filterConfig = arg0;

}

}
这样就解决了问题，我试过了，可以的。

表单提交到后台有乱码解决：
ajax提交的时候用‘data=’+encodeURIComponent('测试')；后台request的时候用String data=new String(request.getParameter("data").getBytes("iso-8859-1"), "UTF-8");

你说返回到前台的信息中文乱码，我想请问你，你怎么接收来自后台的返回信息的呢？
