一、JHipster打包后，在Linux上运行出现如下错误：

2018-08-24 14:35:08.238 ERROR 19063 --- [ject-Executor-1] i.g.j.c.liquibase.AsyncSpringLiquibase   : Liquibase could not start correctly, your database is NOT ready: Could not acquire change log lock.  Currently locked by web_server (192.168.1.94) since 8/24/18 2:28 PM

原因：运行时没有指定运行环境的文件：dev、prod；
在没有指定文件前，还会报错

指定环境文件：
* application.yml里：
*

spring:
    application:
        name: invoiceproject
    profiles:
        # The commented value for `active` can be replaced with valid Spring profiles to load.
        # Otherwise, it will be filled in by maven when building the WAR file
        # Either way, it can be overridden by `--spring.profiles.active` value passed in the commandline or `-Dspring.profiles.active` set in `JAVA_OPTS`
        active: dev

active指定文件：dev或prod；

在开发完成后可以先指定文件；后上传生成服务器；
