这个问题困扰了好久，至少10天！必须拿出来单独写一写！

我网上找了很多相关内容。

有的说是端口冲突，我更改了tomcat的端口，不行。

有的说是没有关闭输入输出流，这个我觉得可能性比较大，但是并不知道是不是出现这个问题的真正原因。总之以后一定要养成好习惯，涉及到输入输出流的一定要关闭。

今天我灵机一动，将web项目移出tomcat的me-weapps目录，tomcat当然运行不了，然后再放入me-weapps中，相当于重新部署该web项目，然后tomcat竟然跑起来了！！！

现在想想，如果出现类似部署问题就应该将tomcat中的项目移出，看看localhost:8080能不能跑起来。
