glassfish 4 上的 jdbc/_default

Question

我正在将现有应用程序从 glassfish 3.1.2 迁移到 glassfish 4

这是我的 persistence.xml

</persistence-unit>

正如文档中所说的选择不同的数据源：

要使用非默认数据库，请为 jta-data-source 元素指定一个值，或者将 transaction-type 元素设置为 RESOURCE_LOCAL 并为 non-jta-data-source 元素指定一个值。

我还使用了这样配置的 Spring RoutingDataSource 策略：

关于版本的一些信息：

我正在使用： 春季 3.1.1-发布 由于之前对使用 JPA1 的限制，Hibernate-entitymanager 3.4.0.GA。 Hibernate-core 3.3.0.SP1

这是在 glassfish 3.1.2 上工作的，但现在的问题是，当我部署应用程序时，它总是使用 jdbc/_default 作为默认数据源。它不关心persistence.xml 和spring beans 配置文件上的数据源。

关于如何解决这个问题的任何想法？

Answer 1

我发现了问题，Glassfish 4 中的 jndi 名称只需要相对名称：

https://glassfish.java.net/docs/4.0/application-development-guide.pdf

对于必须映射到全局 JNDI 名称的所有其他组件依赖项，默认是相对于 java:comp/env 的依赖项名称。 例如，在@Resource(name="jdbc/Foo") DataSource ds;注解，全局 JNDI 名称为 jdbc/Foo

示例 jdbc/DBMine 而不是 java:comp/env/jdbc/DBMine。
