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：）

同学好，感觉是xml文件写错了，格式或者空格方面有些问题，请检查下

https://my.oschina.net/u/2007466/blog/310007，

修改完成后，记得clean tomcat
