可是看这个错误的话就是和空格相关导致读取不了呢 https://blog.csdn.net/baidu_18607183/article/details/49870885
同学直接复制粘贴我的web.xml，然后clean tomcat看看，并且还需要看看其他的xml文件有没有类似的问题。如果怀疑是tomcat的原因，可以更换一个tomcat试试，感觉应该也不是tomcat的问题，就是xml的问题，这种问题由于信息不足也不好帮同学定位，必要的时候可以推倒重来一下，代码直接拷贝现有的就行了，看看拷贝到哪里报错，也是一种解决问题的方法：）

web.xml文件已经检查过，并没有空格或者格式方面的问题，还是tomcat打不开 <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
