[解决办法]
我也遇到过，我全部换成UTF-8就好了，你可以试试。
[解决办法]
或者写一个Filter 过滤
[解决办法]
哎。。。乱码。。。全部采用UTF-8呗。
可能哪个地方你漏了没设。
帮顶咯。
[解决办法]
文件保存是不是 ansii编码，这个有时候会忽略掉。
[解决办法]
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;public class CharacterEncodingFilter implements Filter { public void destroy() { } public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { request.setCharacterEncoding("utf-8"); chain.doFilter(request, response); } public void init(FilterConfig config) throws ServletException { }}
[解决办法]
加上这句试试：<% request.setCharacterEncoding("GBK"); %>
