我的jsps正在查看中,

控制器:
package com.spring.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class LoginController {
@RequestMapping({"/","/login"})
public String login()
{
return "login";
}
}
当我试图击中
http://localhost:8080/Spring-MVC-Security/ ,
url is getting redirected to
http://localhost:8080/Spring-MVC-Security/login
但是我从tomcat收到404错误,并在控制台上收到以下警告:
Jan 13, 2014 12:03:41 PM org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI [/Spring-MVC-Security/WEB-INF/views/login.jsp] in DispatcherServlet with name 'servletDispatcher'
解析视图后,似乎再次击中了ServletDispatcher。
请指教。谢谢
最佳答案
首先,您要加载servletDispatcher
上下文两次。调度程序Servlet将根据约定自动发现/WEB-INF/servletDispatcher-servlet.xml
文件-因此不需要在contextConfigLocation
中指定
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
<!-- Remove servletDispatcher-servlet.xml -->
/WEB-INF/spring-security.xml
</param-value>
</context-param>
尝试将调度程序servlet映射从
/*
更改为/
<servlet-mapping>
<servlet-name>servletDispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
另外-由于您的登录控制器除了返回
login
视图外没有执行其他任何操作,因此可以将其替换为视图控制器。<mvc:view-controller path="/login" />
