本文记录了在使用Mybatis时遇到的配置文件UTF-8编码问题及数据库通信异常的解决过程。首先，由于XML配置文件的编码问题导致解析错误，尝试将UTF-8改为UTF8未果，最终通过将所有UTF-8统一更改为UTF8解决了XML解析异常。随后，遇到了MySQL通信链接失败的问题，通过将`mybatis-config.xml`中的`useSSL`设置为`false`成功修复了通信异常。
1 字节的 UTF-8 序列的字节 1 无效
Mybatis执行代码报错：Cause: org.apache.ibatis.builder.BuilderException: Error creating document instance. Cause: org.xml.sax.SAXParseException; lineNumber: 5; columnNumber: 18; 1 字节的 UTF-8 序列的字节 1 无效。

解决办法三种：
-
将UserMapper.xml 中的UTF-8修改为UTF8
如下图：
-
第一种不行的话，修改mybatis-config.xml中的UTF-8修改为UTF8
如下：
-
如果前两种方法都不行将UserMapper.xml和mybatis-config.xml中的UTF-8都修改为UTF8
我的最后是第三种办法修改成功，结果如下：
