使用jhipster构建微服务，在打包启动是报错：liquibase.exception.LockException: Could not acquire ch_JAVA_编程开发_程序员俱乐部

报错的信息：

   liquibase.exception.LockException: Could not acquire change log lock.

说明：当微服务构建完成后，在resource中有个文件：
/src/main/resources/config/liquibase/changelog/00000000000000_initial_schema.xml

    将内容更改为如下：

更改完后，将数据库中之前新建的表删除，然后重新打包微服务，启动即可！
