Caused by: liquibase.exception.ValidationFailedException: Validation Failed:1 change sets check sum

db/changelog/mysql/changelog-0001-307096-1.0.sql::1.0::buoluo.meng was: 8:a5d8f616a121230c204fd2b8786b27e but is now: 8:a5d8f616a121230c204fd2b8786b27e

这个错其实就是databasechangelog日志表中记录的MD5SUM现在的MD5值与以前保存的不一致。
将在控制台报错的but is now 后面的MD5值复制到把数据库中databasechangelog表的MD5SUM里就行
