使用 Spring BOOT 集成测试 JPA 存储库时出现 NoSuchMethodError (getMetaModel)答案

【问题标题】：NoSuchMethodError (getMetaModel) while integration testing JPA repository with Spring BOOT使用 Spring BOOT 集成测试 JPA 存储库时出现 NoSuchMethodError (getMetaModel)
【发布时间】：2016-06-06 12:15:00
【问题描述】：

我有一个基于 Spring BOOT 的 Web 服务，它使用 Spring 数据 JPA 连接到 MySql DB。我能够毫无问题地运行和部署应用程序。

但是，当我运行集成测试用例时，随着应用程序的配置，我遇到了异常 (java.lang.NoSuchMethodError: javax.persistence.EntityManagerFactory.getMetamodel()Ljavax/持久性/元模型/元模型）

当扩展 JpaRepository 接口的存储库 bean 即将创建时，这将被触发。

当我检查 EntityManagerFactory 接口方法时，我确实找到了 getMetaModel() 方法。

版本

弹簧：4.0
org.eclipse.persistence.jpa : 2.6.3
spring-data-jpa : 1.9.2.RELEASE

如果有人能指出根本原因或进一步的调试步骤，将会很有帮助。

测试类

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {ApplicationService.class, ApplicationServiceImpl.class})
@EnableTransactionManagement
@WebAppConfiguration public class IntegrationTestBase {
    @Autowired
    private ApplicationServiceImpl service;
..
}

【问题讨论】：

可能重复：见stackoverflow.com/questions/10489327/…
@blur0224 问题类似。但是提供的解决方案现在不相关。我确实在异常指出的类中找到了方法。所以需要另一种方法来解决这个问题。
链接的问题是完全相关的......您有 NoSuchMethodError ，因此您在 CLASSPATH 中有一个不合适的“persistence-api”jar 没有该方法。是的，您可能还有另一个持久性 API，但没有找到！
如果只有测试显示该错误，请将您的测试依赖项与您的主要项目依赖项进行比较，并仔细查看 JPA 实体管理器。我的猜测是你会发现问题所在。

【解决方案1】：

进一步调查以下堆栈跟踪的特定部分：

Caused by: java.lang.NoSuchMethodError: javax.persistence.EntityManagerFactory.getMetamodel()Ljavax/persistence/metamodel/Metamodel;
at org.springframework.data.jpa.repository.config.JpaMetamodelMappingContextFactoryBean.getMetamodels(JpaMetamodelMappingContextFactoryBean.java:90)
at org.springframework.data.jpa.repository.config.JpaMetamodelMappingContextFactoryBean.createInstance(JpaMetamodelMappingContextFactoryBean.java:56)
at org.springframework.data.jpa.repository.config.JpaMetamodelMappingContextFactoryBean.createInstance(JpaMetamodelMappingContextFactoryBean.java:26)

我观察到 JpaMetamodelMappingContextFactoryBean.java 指的是一个旧版本的 javax.persistence 库，它被错误地引用了。

我从 maven 中取出了上面的库，并将这个库的依赖关系与 org.eclipse.persistence 库对齐。这有一个 EntityManagerFactory 的实现和 getMetamodel() 方法的实现。

问题就这样解决了。

【解决方案2】：

我有两个具有不同版本（1 和 2）的 javax.persistence 库，它们是从依赖 jars（EclipseLink：2.5.2，其中包括（javax.persistence：2.1.0）和persistence-api：1.0.2 导入的。我需要做的就是将 EclipseLink 移到 pom.xml 中具有 persistence-api:1.0.2 的项目之前。在 document 中定义的依赖顺序很重要：因为 Maven 2.0.9 它是重要的声明：第一个声明获胜。
