spring MVC访问WEB-INF下资源问题

# 1、web项目的WEB-INF #

这个目录下的页面是不能直接访问的，为了安全考虑，我们把jsp页面都放到这里，所以就造成了一个问题，访问页面前都要经过控制器来跳转。

# 2、解决办法 #

## jsp页面,要引入bootstrap，不引入也没事，就是没有样式而已。 ##

## 后台处理 ##

import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.RequestParam;
    import org.springframework.web.bind.annotation.ResponseBody;
    import org.springframework.web.context.request.RequestContextHolder;
    import org.springframework.web.context.request.ServletRequestAttributes;
    import javax.servlet.http.HttpServletRequest;
    /** * Created by qqg on 2017/8/15. */
    @Controller
    public class CustomerController {
        @Autowired
        CustomerService customerService;
        @Autowired
        private HttpServletRequest request;
        @RequestMapping(value="/index",method= RequestMethod.GET)
        public String publishArticle(){
            System.out.println("index");
            return "login";
        }
        //signOut
        @RequestMapping(value="/signOut",method= RequestMethod.GET)
        public String signOut(){
            //清空session,回到首页
            getSession().invalidate();
            return "login";
        }

## 点击主页会跳转到login页面。 ##
