为什么我的jsp跳转不正确？我已经设置好了web.xml

[u010627130]

wel.xml里面有两段关于AdminServlet的：
<servlet>
<description>This is the description of my J2EE component</description>
<display-name>This is the display name of my J2EE component</display-name>
<servlet-name>AdminServlet</servlet-name>
<servlet-class>com.action.AdminServlet</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>AdminServlet</servlet-name>
<url-pattern>/Admin.shtml</url-pattern>
</servlet-mapping>

AdminServlet是这么写的：

我的问题是，为什么会停在了/Admin.shtml上面？这是为什么？

[lt3]

不是已经执行到AdminServlet里面了吗？ 这跟web.xml的url没什么关系了， 说明路径是正确， 不然她怎么能到servlet呢！ 确保没有缓存， 然后用断点在跟踪下。/

[u010627130]

我确定已经跳转到了/Admin.shtml，但是却停在了当前页面中，账号密码也是正确的！ 根据断点的调试，代码走了这里：

if(method.equals("one")){//admin登录
				String username = request.getParameter("username");
				String password = request.getParameter("password");
				if(username == null||username.trim().equals("")){
					request.setAttribute("message", "请正确输入用户名！");
					request.getRequestDispatcher(sysdir+"/login.jsp").forward(request, response);
				}
				else if(password == null||password.trim().equals("")){
					request.setAttribute("message", "请输入密码！");
					request.getRequestDispatcher(sysdir+"/login.jsp").forward(request, response);
				}
				else{
					String md5password = MD5.MD5(password);
					String agent = request.getHeader("user-agent"); 
					StringTokenizer st = new StringTokenizer(agent,";"); 
					String useros=st.nextToken();
					String loginip = request.getRemoteAddr();			
					int flag = loginbean.adminLogin(username,md5password, password,useros,loginip);
					switch (flag){
						case Constant.NAME_ERROR:
							request.setAttribute("message", "用户名错误！请确认管理权限！");
							request.getRequestDispatcher(sysdir+"/login.jsp").forward(request, response);
							break;
						case Constant.PASSWORD_ERROR:
							request.setAttribute("message", "密码错误，请确认管理权限！");
							request.getRequestDispatcher(sysdir+"/login.jsp").forward(request, response);
							break;
					}
				}
			}

匹配 <url-pattern>/Admin.shtml</url-pattern>就跳转了

[u010627130]

引用 2 楼 Acesidonu 的回复:

怎么匹配？在web.xml不是已经写了么？

[u010627130]

引用 2 楼 Acesidonu 的回复:

匹配 <url-pattern>/Admin.shtml</url-pattern>就跳转了

<servlet-mapping> <servlet-name>AdminServlet</servlet-name> <url-pattern>/Admin.shtml</url-pattern> </servlet-mapping> 这个好像不是用的AdminServlet去匹配/Admin.shtml么？

[花谢尊前不敢香]

好好看看url-pattern匹配规则。有扩展名的，直接去掉.扩展名映射

我不是太懂啊， 去掉扩展名之后是不是应该是这样：

<servlet-mapping>
    <servlet-name>AdminServlet</servlet-name>
    <url-pattern>/Admin</url-pattern>
  </servlet-mapping>

可以试试5楼上说的，，，

tomcat默认不会操作shtml的，建议取消server.xml配置文件的注释
