Mybatis和Spring项目突然报错

今天在写接口的时候，运行Tomcat突然报了一大堆错误，记录一下错误原因，以供大家参考

这些错误看起来很多很麻烦，但是大家千万不要被弄晕了，如果你一开始或者前一天项目跑的还好好地，今天突然不能用了，那么肯定是你动了什么东西。
而我这个就是因为xml文件被我更改了，在点击ctrl+z的时候按成fn+z导致xml中出现三个z但是我没看到，而且xml文件中也不会像Java代码那样会报错。
所以，大家出现这种错误，可能就是你的东西被你改了，大家一定细心找找自己更改过的文件，查查是不是哪里写错了。
org.xml.sax.SAXParseException;这个错误就是说明你的xml文件中有编码错误或者存在非法字符！

还有这里跟大家打打气，就是这个错误我找了两天都没找到，通过师兄找了一晚上，最后还是他指了方向自己找到的。以前不懂得看报错的内容，但是现在要学会看报错的内容了。
还有就是一定不能随便放弃，说真的，这个错误我找了两天，我都想放弃回去学习基础了。但是最终找到了错误，真的让人心情大爽，仔细想想，公司里面要的人不就是有解决问题能力的人吗？你如果解决问题能力很强的话，学习的过程也会越来越快，如果你学习速度很快，但是遇到问题没法解决，这样以后的坎坷会越来越多，心情会大打折扣，所以，大家遇到问题一定要迎难而上！加油！！
