####idea2018.3 自带的tomcat JDK1.8
引入的eclipse maven项目编译和启动都成功了没有报错
然后进入localhost8080端口显示空白页面控制台报了如下信息：

2019-07-26 14:31:41.420 [http-nio-8080-exec-1] INFO  o.a.c.core.ContainerBase.[Tomcat].[localhost].[/] - Initializing Spring FrameworkServlet 'dispatcherServlet'

直接在网址输入http://localhost:8080/login 报如下：

####**不知道是什么原因，是tomcat的问题吗？还是拦截器的原因？可是这个是从svn拉下来的，同事的eclipse完美运行**

# 页面默认前缀目录
spring.mvc.view.prefix=/WEB-INF/page/
# 响应页面默认后缀
spring.mvc.view.suffix=.jsp

IDEA 断点设置好了，也看到了本应该传来的值是5，现在是0，怎么找到造成这个结果的地方改正
