Question

我正在尝试运行liquibase以生成当前数据库的变更日志，但是出现以下错误，并且不确定如何解决。

Unexpected error running Liquibase: liquibase.exception.DatabaseException: Connection could not be created to jdbc:postgres://kbjoxiifqvunac:ef1f6ba0b9633d5951c6f4a28897fe390fdf2a7f4189320569d303531899e843@ec2-54-217-235-159.eu-west-1.compute.amazonaws.com:5432/d1pdhars1kb6ep with driver org.postgresql.Driver.

我已经运行了以下命令

liquibase --driver=org.postgresql.Driver --changeLogFile=changelog.xml --url=jdbc:postgres://user:password@ec2-54-217-235-159.eu-west-1.compute.amazonaws.com:5432/dbhost generateChangeLog

由于我将postgres驱动程序放入liquibase的lib文件夹中，因此我省略了classpath标志，并且根据文档应该对其进行扫描。

我正在Windows，Liquibase版本3.8.0和postgres-drivers 42.1.1上运行。有任何想法吗？预先感谢您的帮助

Answer 1

我认为您的驱动程序jar应该位于lib目录中，而不是bin目录中。如果您从liquibase.bat看这些行，您会发现它在bin目录中添加了以liquibase开头的所有jar文件，然后添加了 ALL lib目录中的> jar文件。

set CP=.
for /R %LIQUIBASE_HOME% %%f in (liquibase*.jar) do set CP=!CP!;%%f
for /R %LIQUIBASE_HOME%\lib %%f in (*.jar) do set CP=!CP!;%%f

liquibase generateChangeLog无法创建与jdbc：postgres的连接
