Question

struts2中怎样实现过滤jsp页面的过滤器

Answer 1

如下所示:

package test;
import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

public class LoginFilter implements Filter
{

public void destroy()
{

}

public void doFilter(ServletRequest req, ServletResponse rsp,
FilterChain chain) throws IOException, ServletException
{
chain.doFilter(req, rsp);
}

public void init(FilterConfig arg0) throws ServletException
{

}

}

在web.xml里面配置

<filter>
<filter-name>logFilter</filter-name>
<filter-class>test.LoginFilter</filter-class>

</filter>
<filter-mapping>
<filter-name>logFilter</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
