我正在使用Liquibase 3.3.2并尝试实现一个接受大量更改日志的Web服务，根据上下文查找特定的DataSource，并将该DataSource与liquibase ChangeLogs一起使用以执行数据库更新。
我使用PostgreSQL作为数据库。
不知何故，从Web服务端登录的liquibase表明根本没有问题，所有似乎都正确执行。但是，数据库中没有表格，甚至Liquibase自己的锁定/状态表也没有。
这是在启用Liquibase的调试日志记录的情况下记录Web服务：

如果我将一个Writer对象传递给Liquibase.update（），它会填充正确的SQL，我可以从pgAdmin手动执行所需的结果，所以我知道它不会生成无效的SQL：

我在这里缺少什么？是否缺少提交？我的DataSource出了什么问题？ Liquibase中有一些（un）设置状态？
答案 0 :(得分：0)
我在这里发布问题后很快就找到了原因，所以回答我自己的问题：
将Writer对象传递给Liquibase会将生成的SQL捕获到该Writer，但阻止将其发送到数据库。
因此，简单地说，不传递Writer对象实际上会使SQL进入数据库，在这种情况下，它都可以正常工作。
此行为未记录，也未立即从源中清除。
