org.apache.ibatis.exceptions.PersistenceException:
Error building SqlSession.
The error may exist in com/kuang/dao/UserMapper.xml
Cause: org.apache.ibatis.builder.BuilderException: Error parsing SQL Mapper Configuration. Cause: org.apache.ibatis.builder.BuilderException: Error creating document instance. Cause: org.xml.sax.SAXParseException; lineNumber: 6; columnNumber: 14; 1 字节的 UTF-8 序列的字节 1 无效。
org.apache.ibatis.exceptions.PersistenceException:
Error building SqlSession.
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：将mybaits-config.xml和UserMapper.xml配置文件中的头部UTF-8改为UTF8
如果项目还有其他 .xml配置文件，可以修改一下
pom.xml文件不用改
