tomcat运行一段时间会乱码

Question

我在tomcat6的server.xml中配置URIEncoding=“GBK”，启动tomcat一切正常，可是在运行一段时候后就出现了乱码，重启tomcat就又正常了，不知道是什么原因，请高手指教，谢谢

自己写一个过滤器: 
public class DoFilter implements Filter 
{ public void destroy() { 
} public void doFilter(ServletRequest arg0, ServletResponse arg1, 
FilterChain arg2) throws IOException, ServletException { arg1.setCharacterEncoding("GBK"); 
arg2.doFilter(arg0, arg1); } public void init(FilterConfig arg0) throws ServletException { 
} } 在web。xml中配置： <!-- 过滤器 --> 
  <filter> 
    <filter-name>encodingFilter </filter-name> 
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter </filter-class> 
    <init-param> 
        <param-name>encoding </param-name> 
        <param-value>UTF-8 </param-value> 
    </init-param> 
    <init-param> 
        <param-name>forceEncoding </param-name> 
        <param-value>true </param-value> 
    </init-param> 
  </filter> 
  <filter-mapping> 
    <filter-name>encodingFilter </filter-name> 
    <url-pattern>*.jsp </url-pattern> 
  </filter-mapping>  
  <filter-mapping> 
    <filter-name>encodingFilter </filter-name> 
    <url-pattern>*.do </url-pattern> 
  </filter-mapping>
