利用JSP中的过滤器解决中文乱码问题
首先我们创建过过滤器:
package com.gbx; 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 Zh_Filter implements Filter{ public void destroy() { // TODO Auto-generated method stub System.out.println("destroy ..."); } public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { //设置内置对象的字符集 request.setCharacterEncoding("gb2312"); response.setCharacterEncoding("gb2312"); //处理过滤 chain.doFilter(request, response); } public void init(FilterConfig arg0) throws ServletException { // TODO Auto-generated method stub System.out.println("init .. "); } }
然后再web.xml中配置过滤器:
<filter> <filter-name>filter</filter-name> <filter-class>com.gbx.Zh_Filter</filter-class> </filter> <filter-mapping> <filter-name>filter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
