28?????????try
29?????????{
30?????????????request.setCharacterEncoding("GBK");
31?????????????//為請求“放行”
32?????????????chain.doFilter(request,?response);?//此處不需要鏈參數?
33?????????}
34?????????catch?(Exception?e)
35?????????{
36?????????????e.printStackTrace();

在web.xml中，添加
1?<filter>?
2?????????<filter-name>encodingfilter</filter-name>?
3?????????<filter-class>filter.EncodingFilter</filter-class>?
4?????</filter>
5?????<filter-mapping>?
6?????????<filter-name>encodingfilter</filter-name>?
7?????????<url-pattern>/*</url-pattern>?
8?????</filter-mapping>?
則所有的請求頁面都會通過EncodingFilter將請求參數轉換成中文
