java - 将 hyperjaxb3 升级到 jpa 2.1

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。当我尝试从 eclipse 中执行 Run As..Run on Server 时出现以下错误:

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

我在项目的根文件夹上运行了 mvn dependency:tree，问题似乎是 hyperjaxb3 使用的是 JPA 2.0，它与 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可以解决此错误，以便我的应用程序无需删除 hyperjaxb3 即可享受 JPA 2.1 的优势？

这是我从 mvn dependency:tree 从 windows 命令行在 eclipse 项目的根文件夹中得到的输出:

由于 org.jvnet.hyperjaxb3:hyperjaxb3-ejb-roundtrip，您得到了冲突的 org.hibernate.javax.persistence:hibernate-jpa-2.0-api compile 范围内的依赖项。这实际上是不正确的，should be 提供 代替。 hyperjaxb3-ejb-roundtrip 可以安全地假设提供了 JPA API 和 hyperjaxb3-ejb-runtime。这将在未来的版本中得到纠正。

首先，确保您确实需要 hyperjaxb3-ejb-roundtrip。仅当您生成往返测试用例时才需要 - 这实际上仅适用于“ Playground ”。在生产项目中，您通常不需要这个。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，您可以使用Maven 的dependency exclusion 机制。将 hibernate-jpa-2.0-api 依赖项排除在由于 hyperjaxb3-ejb-roundtrip 而被传递排除之外。这看起来像:

<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>

如果您已经直接包含 hyperjaxb3-ejb-runtime，您也可以将其从 hyperjaxb3-ejb-roundtrip 中排除。

接下来，我刚刚在 this test project 中尝试了 JPA 2.1 兼容性。 .我必须将 hsqldb 更新为 2.3.2 但除此之外，它还适用于 hibernate-entitymanager 版本 4.3.7.Final 和 hibernate-jpa-2.1-api 版本 1.0.0.Final。该测试不是特别具有代表性，但它很好地表明 Hyperjaxb 与 JPA 2.1 兼容。 JPA 2.1 很可能向后兼容 JPA 2.0，因此实际上 Hyperjaxb 生成的代码也应该与 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 ，另一个到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，并且在少数情况下(如 hibernate-jpa-2.x-api)还需要 Artifact 编号。 HSQLDB 必须更新到 org.hsqldb:hsqldb 版本 2.3.2 及更高版本，但这没什么大不了的。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。
