我的Url pattern 是REST风格的。
<servlet>
<servlet-name>leslie-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>leslie-dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
1、如果你有全局拦截器，请先将拦截器设置为，对"/"放行
/**
* 登录拦截器
*
*/
@Interceptor
public class UserLoginInterceptor extends HandlerInterceptorAdapter {
private static final String[] IGNORE_URI = { "/","/loginPage", "/checkLogin","/hello" };
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
throws Exception {
// System.out.println("拦截到");
boolean flag = false;
String url = request.getRequestURL().toString();
for (String s : IGNORE_URI) {
if (url.contains(s)) {
flag = true;
break;
}
}
if (!flag) {
User user = SJLoginController.getLoginUser(request);
if (user != null) {
// List<String> urls = SJLoginController.getUserRoleUrls(request);
// if(urls.contains(url)){
// flag = true;
// }
flag = true;
}
}
return flag;
}
}
2、为"/"专门添加一个welcomeController
@Controller
public class WelcomeController {
@RequestMapping("/")
public ModelAndView welcome(){
return new ModelAndView("welcome");
}
}
3、在web.xml中添加welcome file
<welcome-file-list>
<welcome-file>/</welcome-file>
</welcome-file-list>
4、在welcome.jsp页面中跳转到登录页面
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title></title> </head> <body> <jsp:forward page="/login/loginPage"></jsp:forward> </body> </html>
