在J2EE编程中， Struts框架怎样用过滤器解决中问乱码问题？

(1)先定义一个过滤器，实现Filter接口

(2)在配置文件中配置一下

就OK了！

定义一个过滤器,代码如下: 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 EncodingFilter implements Filter { private String ecoding; @Override public void destroy() { // TODO Auto-generated method stub } @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { // TODO Auto-generated method stub request.setCharacterEncoding("UTF-8"); response.setCharacterEncoding("UTF-8"); chain.doFilter(request, response); } @Override public void init(FilterConfig config) throws ServletException { // TODO Auto-generated method stub } } 在web.xml配置一下就OK,配置如下: <filter> <filter-name>EncodingFilter</filter-name> <filter-class> com.aptech.jb.epet.filter.EncodingFilter </filter-class> </filter> <filter-mapping> <filter-name>EncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> 这样就可以解决中文乱码问题了
