我有一个在 Tomcat7 上运行的基于 spring-mvc maven 的 Web 项目。这是我在运行 Application.class 时遇到的错误。我如何解决不匹配的歌手以及正在引用哪个包，在下面提供了我的 pom

java.lang.SecurityException: class "javax.persistence.PersistenceContext"'s signer information does not match signer information of other classes in the same package

背景

此异常的原因是您的类路径中有多个 jar 文件，它们引用了不同JPA提供者（实现）在多个版本中的 JPA 规范。

解决方案

pom.xml从您的文件中删除以下依赖项。

  • <dependency>
      <groupId>org.hibernate.javax.persistence</groupId>
      <artifactId>hibernate-jpa-2.1-api</artifactId>
      <version>1.0.2.Final</version>
</dependency>

  • <dependency>
      <groupId>org.eclipse.persistence</groupId>
      <artifactId>javax.persistence</artifactId>
      <version>2.2.1</version>
</dependency>

  • <dependency>
      <groupId>org.eclipse.persistence</groupId>
      <artifactId>org.eclipse.persistence.jpa</artifactId>
      <version>2.7.3</version>
</dependency>

这将导致只剩下 1 个 jar 文件，它定义了javax.persistence.PersistenceContext：

  • javax.persistence-api-2.2.jarhibernate-core-5.4.19.jar它由Hibernate ORM 提供程序临时引用。

通过这些更改，您可以清理类路径并解决您遇到的运行时错误。
