1 package filter;
2
3 import javax.servlet.Filter;
4 import javax.servlet.FilterConfig;
5 import javax.servlet.FilterChain;
6 import javax.servlet.ServletRequest;
7 import javax.servlet.ServletResponse;
8 import javax.servlet.http.HttpServletRequest;
9 import javax.servlet.http.HttpServletResponse;
10 import javax.servlet.ServletContext;
11
12 public class EncodingFilter implements Filter
13 {
14     private FilterConfig config;
15
16     public void init(FilterConfig config)
17     {
18         this.config = config;
19     }
20
21     public void destroy()
22     {
23         this.config = null;
24     }
25
26     public void doFilter(ServletRequest request,ServletResponse response,FilterChain chain)
27     {
28         try
29         {
30             request.setCharacterEncoding("GBK");
31             //为请求“放行”
32             chain.doFilter(request, response); //此处不需要链参数
33         }
34         catch (Exception e)
35         {
36             e.printStackTrace();
37         }
38     }
39 }
40

在web.xml中，添加

1 <filter>
2         <filter-name>encodingfilterfilter-name>
3         <filter-class>filter.EncodingFilterfilter-class>
4     filter>
5     <filter-mapping>
6         <filter-name>encodingfilterfilter-name>
7         <url-pattern>/*
8

则所有的请求页面都会通过EncodingFilter将请求参数转换成中文
