我的web.xml配置如下：
<filter>
<filter-name>shiFilter</filter-name>
<filter-class>myFilter.SetcharEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>gb2312</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>shiFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
包myFilter里的SetcharEncodingFilter类执行成功了的，不知道为什么出来此错误。
----------------解决方案--------------------------------------------------------
你的xml是正确的
从你的输出我找不到原因
你把你的SetcharEncodingFilter.java发上来看看
----------------解决方案--------------------------------------------------------
package myFilter;
import java.io.*;
import javax.servlet.*;
public class SetCharEncodingFilter implements Filter
{
String encoding=null;
FilterConfig filterconfig=null;
boolean ignore=true;
public void destroy()
{this.encoding=null;
this.filterconfig=null;
}
public void doFilter(ServletRequest request,ServletResponse response,FilterChain chain)throws IOException,ServletException
{
if(ignore||(request.getCharacterEncoding()==null))
{String encoding=selectEncoding(request);
if(encoding!=null)
{request.setCharacterEncoding(encoding);}
}
chain.doFilter(request,response);
}
public void init(FilterConfig filterConfig)throws ServletException
{
this.filterconfig=filterConfig;
this.encoding=filterConfig.getInitParameter("encoding");
String value=filterConfig.getInitParameter("ignore");
if((value==null)||(value.equalsIgnoreCase("true"))||(value.equalsIgnoreCase("yes")))
this.ignore=true;
else
this.ignore=false;
}
protected String selectEncoding(ServletRequest request)
{return (this.encoding);
}
}
编译没有问题的，多谢指教！
