同学你好。既然产生了楼下的404页面。Tomcat本身是没有问题的。

注意出现404页面和出现白屏的情况不同。一般来说，白屏的情况有几种可能：

1）项目没有成功发布到Tomcat中 

2）Servlet运行时控制台console报错 

3）Servlet跳转失败 

4）页面留在了Servlet没有跳转等等。

综上同学的需要先看一下请求对应的流程上是否有卡住的

1、可以对比检查一下GlobalController是否有拼写错误，这里的路径是否不匹配 :http://img1.sycdn.imooc.com//climg/5dba4caa09ca372917180627.jpg

        } catch (InvocationTargetException e) {

        }
    }
}

2、检查下对应的方法是否已经实现，转发是否写错，是否漏写了forword：

http://img1.sycdn.imooc.com//climg/5dba4d0d090a302113810284.jpg

3、页面对应的路径是否能找到：

    现在连Tomcat的首页都是404错误，请问这是什么原因啊
    2019-10-30 19:39:52
芝芝兰兰 2019-10-30 18:13:11

同学你好。看同学控制台输出的信息中并没有报错呢，只是日志。看同学的项目上下文路径为“/icake_war_exploded”同学是否是使用“localhost:8080/icake_war_exploded”访问的呢？

http://img1.sycdn.imooc.com//climg/5db95ac809adc27308260522.jpg

如果没有解决，可以将访问地址及404页面截一下图。另外提供下这个页面的截图
