Question

我试图在OpenShift（JBoss企业应用程序平台6）上部署我的应用程序，并且我得到了标题中提到的NoSuchMethodError。所以我搜索了整个事情并发现了一些文章或线程，提到自JPA-API 2.1以来这个方法是可用的。我发现Openshift所需的依赖包含JPA-API 2.0。我试图排除这种依赖，但它不起作用。有任何想法吗？请在下面找到pom.xml。

Answer 1

这里的问题是容器在运行时提供了JPA 2.0 。在pom.xml中排除提供的依赖项仅在编译时有效。要解决此问题，您必须在容器中配置类加载。

OpenShift JavaEE 6支持基于JBoss AS 7.来自Class Loading in AS7文档：

jboss-deployment-structure.xml是JBoss特定的部署描述符，可用于控制细粒度的类加载方式。它应该放在META-INF的顶级部署中（或用于Web部署的WEB-INF）。它可以执行以下操作：

Prevent automatic dependencies from being added Add additional dependencies ...

因此，您需要添加自定义jboss-deployment-structure.xml文件，以排除hibernate-jpa-2.0-api自动添加。

基于OpenShift's documentation：

<jboss-deployment-structure> <deployment> <exclusions> <module name="javax.persistence.api" /> </exclusions> </deployment> </jboss-deployment-structure>

Answer 2

将此Maven依赖项添加到您的pom.xml：

<dependency>
    <groupId>org.hibernate.javax.persistence</groupId>
    <artifactId>hibernate-jpa-2.1-api</artifactId>
    <version>1.0.0.Final</version>
</dependency>
