我使用Hibernate将Roo生成的Spring MVC应用程序连接到PostgreSQL。我试图将Flyway 1.6作为一个bean集成到Spring应用程序上下文中。 “有些东西阻止”迁移被执行，并且由于Hibernate元数据验证导致上下文初始化出错。 使用Flyway 1.6 Maven插件（clean，init，migrate）执行迁移没有问题。在Spring应用程序中无法迁移使用Flyway 1.6
Flyway 1.5（以前的版本）的整合工作得很好。
我应该怎么做才能让Flyway 1.6集成迁移工作？ 我应该提供哪些额外配置？环境：Ubuntu 11.10，Springsource工具套件2.9.1（Eclipse 3.7.2），OpenJDK 6b23，Tomcat 7.0.23，PostgreSQL 8.4.9/9.1，Spring 3.0/3.1，Hibernate 3.6.4.Final，PostgreSQL本机驱动程序8.4 JDBC3/4构建702

一切正常[flyway-core-1.7-SNAPSHOT.jar]（http://code.google.com/p/flyway/issues/detail?id=242#c4）。 非常感谢。期待Flyway的下一个版本 - 一个非常有价值的DB迁移工具。祝你好运！ – Artemas 2012-04-19 11:38:16
感谢您的反馈！总是让我开心:-) 1.6.1已经解决了。 – 2012-04-21 12:02:37
