CannotCreateTransactionException 500-异常

Request processing failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is java.sql.SQLException: validateConnection false] with root cause。

maven+ssm项目+mysql8+druid连接池1.0.20版本

就是因为德鲁伊druid的jar包错误才导致这个异常

之后我换成了以下依赖，测试成功了！

    
    
    
      com.alibaba
      druid
      1.1.10
