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 }

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>
则所有的请求页面都会通过EncodingFilter将请求参数转换成中文
