MySQL5.7 SQL文件执行到“Begin；”，报SQL注入

一执行到开启事务的begin语句，就会报异常，知道怎么解决吗？
druid版本：1.1.18
简要异常信息：
Caused by: java.sql.SQLException: sql injection violation, syntax error: syntax error, error in :'BEGIN', expect END, actual EOF pos 5, line 1, column 6, token EOF : BEGIN
at com.alibaba.druid.wall.WallFilter.checkInternal(WallFilter.java:806)
at com.alibaba.druid.wall.WallFilter.check(WallFilter.java:788)

Start with the reported failure in com.alibaba.druid.wall.WallFilter at WallFilter.java:806 and the surrounding check path at line 788. Reproduce the BEGIN statement with Druid 1.1.18 against MySQL 5.7 and inspect how it is parsed. Done means a transaction-opening BEGIN is accepted without a SQL injection violation, with regression coverage for the case.
