摘要: 过滤器的问题!

在JBuilder里加了一个Filter Servlet

运行时为什么会把图片都过滤掉了.图片都显示不出来.

请问怎么才能把图片显示出来

把你的Filter贴上来

---

public void doFilter(ServletRequest request, ServletResponse response,
FilterChain filterChain) {
boolean valid = false;
HttpServletRequest hres = (HttpServletRequest)request;
HttpSession session = hres.getSession();

try {
if((session!= null)&&(session.getAttribute("userName")!=null))
valid = true;
if(valid)
{
filterChain.doFilter(request, response);
}
else
{
request.getRequestDispatcher("/Login.jsp").forward(request,response);
}
} catch (ServletException sx) {
filterConfig.getServletContext().log(sx.getMessage());
} catch (IOException iox) {
filterConfig.getServletContext().log(iox.getMessage());
}
}

判断一下后缀名
