完美解决中文乱码的问题
1 借助spring
web.xml中增加
package com.filter;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.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;/*** * 创建人：金鑫* 创建时间：2008-9-21 下午03:27:03* 类作用：中文转码过滤器**/@SuppressWarnings("serial")public class ChineseFilter extends HttpServlet implements Filter{private FilterConfig filterConfig;public void init(FilterConfig filterConfig) throws ServletException{ this.filterConfig = filterConfig;}public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain){ try { String encoding = filterConfig.getInitParameter("encoding"); //从WEB.xml配置文件中取出参数，这样我们可以通过配置修改编码格式. request.setCharacterEncoding(encoding);//设置请求的编码格式 filterChain.doFilter(request, response); } catch (ServletException sx) { filterConfig.getServletContext().log(sx.getMessage()); } catch (IOException iox) { filterConfig.getServletContext().log(iox.getMessage()); }}public void destroy(){}protected void doGet(HttpServletRequest arg0, HttpServletResponse arg1) throws ServletException, IOException{ super.doGet(arg0, arg1);}protected void doPost(HttpServletRequest arg0, HttpServletResponse arg1) throws ServletException, IOException{ super.doPost(arg0, arg1);}/*** @function 验证数据是否为空，如果为空则转换* @param param* @return String*/public String checkNull(String param){ if (param == null || param.equals("")) { return ""; } else { return param; }}}?
OK，完美解决掉啦。
其实解决乱码很简单的，就是通过过滤器来实现的，呵呵很简单吧？
