使用过滤器访问页面出现404错误

[lymne]

过滤器只过滤page文件夹下的jsp，一旦没有登陆而访问则跳转回index.jsp

当我在浏览器输入http://localhost:8080/weibodemo/page/homepage.jsp的时候
页面出现的是
HTTP Status 404 - /weibodemo/page/index.jsp

Filter代码
public void doFilter(ServletRequest request,ServletResponse response,FilterChain chain)throws IOException,ServletException{
HttpServletRequest req=(HttpServletRequest) request;
HttpSession ses=req.getSession();
if(ses.getAttribute("uesrid")!=null){
chain.doFilter(request, response);
}else{
request.getRequestDispatcher("index.jsp").forward(request,response); }
}


xml配置

<filter>
<filter-name>LoginFilter</filter-name>
<filter-class>weibodemo.filter</filter-class>

</filter>
<filter-mapping>
<filter-name>LoginFilter</filter-name>
<url-pattern>/page/*</url-pattern>
</filter-mapping>

什么意思？直接http://localhost:8080/weibodemo/index.jsp也报错？这没影响吧，这请求又不会被过滤

resopnse.sendRedi后面的不会拼了哈哈

直接改成request.getRequestDispatcher("/index.jsp").forward(request,response);试试

[Asura211]

request.getRequestDispatcher("../index.jsp").forward(request,response); 或者 request.getRequestDispatcher(request.getContextPath() + "index.jsp").forward(request,response); 还有我觉得这里用重定向是不是好点？

改成request.getRequestDispatcher("../index.jsp").forward(request,response);之后连index.jsp的都访问不了了
