mybatis

错误1：Error creating document instance.  Cause: org.xml.sax.SAXParseException; lineNumber: 16; columnNumber: 102; 对实体 "characterEncoding" 的引用必须以 ';' 分隔符结尾。

解决：在xml配置文件中配置数据库utl时，要使用&的转义字符也就是&

<property name="url" value="jdbc:mysql://localhost:3306/email?useUnicode=true&amp;characterEncoding=UTF-8" />

错误2：

Unknown initial character set index '255' received from server. Initial client character

解决：加上黄色背景的字串

 

<property name="url" value="jdbc:mysql://localhost:3306/email?useUnicode=true&amp;characterEncoding=UTF-8" />
