The user specified as a definer ('root'@'%') does not exist

当对数据库进行操作的时候，会遇到root无操作权限问题。

一般会提示如下：

org.hibernate.exception.GenericJDBCException: Could not execute JDBC batch update

at org.hibernate.exception.SQLStateConverter.handledNonSpecificException(SQLStateConverter.java:103).......

Caused by: java.sql.BatchUpdateException: The user specified as a definer ('root'@'%') does not exist

at com.mysql.jdbc.PreparedStatement.executeBatchSerially(PreparedStatement.java:2007)

at com.mysql.jdbc.PreparedStatement.executeBatch(PreparedStatement.java:1443).........

要做的就是将所有sql权限赋予root。两个步骤即可解决：

1、 grant all privileges on *.* to root@"%" identified by ".";

Query OK, 0 rows affected (0.11 sec)

2、flush privileges;

Query OK, 0 rows affected (0.08 sec)

具体操作见下图：

权限已经授权完毕。
