Encountered unexpected token: "ur" <K_ISOLATION>

在用mybatis-plus的过程中 , 报如下错误 :

Caused by: net.sf.jsqlparser.parser.ParseException: Encountered unexpected token: "ur" <K_ISOLATION>
at line 4, column 27.

Was expecting one of:

";"
"ACTION"
"ACTIVE"
"ALGORITHM"

 

发现是关键字冲突 , ur 不能作为别名, 将 ur 改为别的后正常
