Question

我正在尝试在使用maven，jpa，hibernate和hyperjaxb的eclipse项目中升级到JPA 2.1。当我尝试在eclipse中执行Run As..Run on Server时，我收到以下错误：

java.lang.NoSuchMethodError: javax.persistence.Table.indexes()[Ljavax/persistence/Index;

我在项目的根文件夹上运行mvn dependency:tree，问题似乎是hyperjaxb3正在使用JPA 2.0，这与JPA 2.1冲突。有没有办法让hyperjaxb3使用JPA 2.1？或者是否有其他方法来解决此错误，以便我的应用程序可以获得JPA 2.1的好处而无需删除hyperjaxb3？

以下是我从windows命令行在eclipse项目的根文件夹中从mvn dependency:tree获得的输出：

由于在org.hibernate.javax.persistence:hibernate-jpa-2.0-api范围内具有org.jvnet.hyperjaxb3:hyperjaxb3-ejb-roundtrip依赖关系，您会收到有冲突的compile。这实际上是错误的，should be provided。 hyperjaxb3-ejb-roundtrip可以安全地假设提供了JPA API和hyperjaxb3-ejb-runtime。这将在以后的版本中得到纠正。

首先，确保您确实需要hyperjaxb3-ejb-roundtrip。只有在生成往返测试用例时才需要这样做 - 实际上只适用于“游乐场”。在生产项目中，您通常不需要这样做。因此，您可以很好地关闭往返测试用例生成并删除hyperjaxb3-ejb-roundtrip依赖项。

接下来，如果您确实需要hyperjaxb3-ejb-roundtrip，则可以使用Maven的dependency exclusion机制排除因hibernate-jpa-2.0-api而被传递排除的hyperjaxb3-ejb-roundtrip依赖关系。这看起来像是：

<dependency>
    <groupId>org.jvnet.hyperjaxb3</groupId>
    <artifactId>hyperjaxb3-ejb-roundtrip</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.hibernate.javax.persistence</groupId>
            <artifactId>hibernate-jpa-2.0-api</artifactId>
        </exclusion>
    </exclusions>
</dependency>

如果您已直接添加hyperjaxb3-ejb-runtime，则可以将其从hyperjaxb3-ejb-roundtrip中排除。

接下来，我刚刚在this test project中试用了JPA 2.1兼容性。我必须将hsqldb更新为2.3.2，但除此之外，它适用于hibernate-entitymanager版本4.3.7.Final和hibernate-jpa-2.1-api版本1.0.0.Final。该测试不是特别代表，但它很好地表明Hyperjaxb与JPA 2.1兼容。 JPA 2.1很可能与JPA 2.0向后兼容，因此实际上Hyperjaxb生成的代码也应与JPA 2.1兼容。

我现在已经提交了两个问题，一个是move Hyperjaxb to JPA 2.1，另一个是support new JPA 2.1 features。

迁移到JPA 2.1应该非常简单，因为它（希望）只需要更新依赖版本，在少数情况下（如hibernate-jpa-2.x-api）也需要更新神器ID。 HSQLDB必须更新到org.hsqldb:hsqldb版本2.3.2及更高版本，但这不是什么大问题。我将在下一个版本中实现它。

支持新的JPA 2.1功能需要做更多的工作。

现在是一个小旁注。发布链接以跳转共享其他外部资源时，请清楚说明许可证或链接资源的合法状态。我只会根据所有用户的优势，在可以安全地作为测试或样本添加到项目中的来源咨询公益。

将hyperjaxb3升级到jpa 2.1
