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(); }

ajax交互servlet返回数据和jdbc模糊查询-中文-已经设置了UTF-8和解决了乱码

请使用下面的编码过滤器：

public class CharacterEncodingFilter implements Filter {
protected String encoding = null;

protected FilterConfig filterConfig = null;

protected boolean ignore = true;

public void destroy() {
this.encoding = null;
this.filterConfig = null;
}

public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {

if (ignore || (request.getCharacterEncoding() == null)) {

String encoding = this.encoding;
if (encoding != null)
request.setCharacterEncoding(encoding);
}

chain.doFilter(request, response);

}

public void init(FilterConfig filterConfig) throws ServletException {

this.filterConfig = filterConfig;
this.encoding = filterConfig.getInitParameter("encoding");
String value = filterConfig.getInitParameter("ignore");
if (value == null)
this.ignore = true;
else if (value.equalsIgnoreCase("true"))
this.ignore = true;
else if (value.equalsIgnoreCase("yes"))
this.ignore = true;
else
this.ignore = false;

}

}
并在web.xml中配置：
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>CharacterEncodingFilter</filter-class>

<init-param>

<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>

<init-param>
<param-name>ignore</param-name>

<param-value>true</param-value>
</init-param>
</filter>

<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<servlet-name>/</servlet-name>
</filter-mapping>

页面编码，<meta http-equiv="Content-Type" content="text/html; charset=GBK" />
文件的保存编码改成GBK
乱码一般就这几个地方改了就好了

页面上的编码方式改成GBK了没追问我直接在服务器上进行输出的

追答对啊，但是参数是通过ajax从页面上传过来的，文件的保存方式也要一样（你用的eclipse的话）
