Question

我正在尝试使用liquibase（3.3），postgresql（9.4）和spring-boot创建一个新的数据库模式。相关代码和例外粘贴在下面。

我在我的本地postgresql服务器上创建了空测试数据库。

当您运行liquibase基本脚本时，它正在创建另外两个表来通过liquibase跟踪数据库更新。

表名

databasechangelog
databasechangeloglock

但您不需要手动创建它们。它会在运行liquibase脚本时自动创建。

我认为你必须手动（命令行）liquibase脚本来根据你的liquibase脚本在增量更新的数据库之后创建这些表和其他表（只有一次）。

尝试通过liquibase，postgresql，spring boot创建新数据库。 Result-＆GT; “databasechangelog”不存在
