我有使用 Hibernate 连接到 PostgreSQL 的 Roo 生成的 Spring MVC 应用程序。我正在尝试将 Flyway 1.6 作为 bean 集成到 Spring 应用程序上下文中。“某些事情阻止”迁移被执行，并且我在由 Hibernate 元数据验证引起的上下文初始化时出错。使用 Flyway 1.6 Maven 插件（clean、init、migrate）执行迁移没有问题。
Flyway 1.5（以前的版本）的集成工作得很好。
我应该怎么做才能使 Flyway 1.6 集成迁移工作？我应该提供什么额外的配置？
环境：Ubuntu 11.10、Springsource Tool Suite 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 Native Driver 8.4 JDBC3 /4 构建 702。
