页面的跳转问题

[zhaozheng821018]

我新建的web工程附加有struts和hibernate支持，同时配置好一个Fliter，命名为CheckFliter.java，代码如下：

package sys;

import java.io.IOException;
import java.util.Date;
import java.util.Iterator;
import java.util.List;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import Data.sys.user.SysUser;
import Data.sys.user.SysUserDAO;

import common.GlobleVariables;
import common.PowerCheck;

public class CheckFliter implements Filter {

	public void destroy() {
		// TODO Auto-generated method stub

	}

	public void doFilter(ServletRequest request, ServletResponse response,
			FilterChain next) throws IOException, ServletException {
		// TODO Auto-generated method stub
		// 获取请求路径
		String url = ((HttpServletRequest) request).getRequestURI().toLowerCase();
		SysUser sysuser = new SysUser();
		SysUserDAO sysuserdao = new SysUserDAO();
		HttpSession session = ((HttpServletRequest) request).getSession();
		// 登录请求
		if (url.indexOf(GlobleVariables.login) == 0 || url.substring(GlobleVariables.rootdirectory.length()).endsWith("/") || url.equals(GlobleVariables.loginpage)) {
			String userid = ((HttpServletRequest) request).getParameter("userid");
			String password = ((HttpServletRequest) request).getParameter("password");
			if(userid == null){
				System.out.println("V_V");
				request.getRequestDispatcher(GlobleVariables.loginpage.substring(GlobleVariables.rootdirectory.length())).forward(request, response);
			}
			try {
				List list = sysuserdao.findByProperty("userid",userid);
				Iterator it = list.iterator();
				if (it.hasNext()) {
					String pw = ((SysUser)it.next()).getPassword();
					if (pw.equals(password)) {
						// 登录成功
						session.setAttribute("USERID", userid);
						System.out.println(userid + "登录成功！ " + (new Date()));
						((HttpServletResponse) response).sendRedirect(GlobleVariables.mainpage);
					} else {
						// 登录失败
						((HttpServletResponse) response).sendRedirect(GlobleVariables.loginpage);
					}
				}
			} catch (Exception e) {
				// TODO: handle exception
				e.printStackTrace();
				System.out.println("登录失败！");
				((HttpServletResponse) response).sendRedirect(GlobleVariables.loginpage);
				return;
			} finally {
				try {
					sysuserdao.getSession().close();
				} catch (Exception e) {
					// TODO: handle exception
					System.out.println("session无法关闭！");
				}
			}
			return;
		}
		// 登出请求
		if (url.indexOf(GlobleVariables.logout) >= 0) {
			session.removeAttribute("USERID");
			((HttpServletResponse) response).sendRedirect(GlobleVariables.loginpage);
			return;
		}
		// 其他请求
		if (true) {
			if ((session.getAttribute("USERID") != null) ) {
			// 已经登录成功
			if (PowerCheck.check((HttpServletRequest) request)) {
				// 具有访问权限
				((HttpServletRequest) request).getRequestDispatcher(url.substring(GlobleVariables.rootdirectory.length())).forward(request, response);
			} else {
				// 不具有访问权限
				 ((HttpServletResponse)response).sendRedirect(GlobleVariables.errorpage);
			}
			return;
			}else{
				//			未登录
				((HttpServletResponse) response).sendRedirect(GlobleVariables.loginpage);
			}
		}
				next.doFilter(request, response);
	}

	public void init(FilterConfig arg0) throws ServletException {
		// TODO Auto-generated method stub

	}

}

其中的globlevariables的代码如下：

package common;

public class GlobleVariables {
	public final static String login = "/oa/u_login";
	public final static String loginpage = "/oa/log_in.jsp";
	public final static String logout = "/oa/u_logout";
	public final static String logoutpage = "/pa/log_out.jsp";
	public final static String mainpage = "/oa/index.jsp";
	public final static String rootdirectory = "/oa";
	public final static String errorpage = "/oa/common/error.jsp";
	public final static String[] filetofilter = {".html",".htm"};
	public final static String pagetext = "text/html; charset=GBK";
}

在这样的模式下，我能正常的登录到首页index.jsp，但是在新建servlet以后，要submit到新建的servlet就会提示错误，如下：

type Status report

message /oa/servlet/packcontrol

description The requested resource (/oa/servlet/packcontrol) is not available.

/oa/servlet/packcontrol时不可用的，好好检查一下你的servlet名字

[Quote=引用楼主 zhaozheng821018 的回复:]
The requested resource (/oa/servlet/packcontrol) is not available.

你前面列出来的那些代码中没有任何/oa/servlet/packcontrol这样的相关代码啊。

通常这个错是提交的目标不对，
如果该URL其实是对的，
那么就是过滤器中将对该Servlet的访问禁止了。
