【问题描述】:
我正在尝试将使用休眠 JPA 的后端应用程序开发到 Tomcat 中。 从现在开始,它在 JPA 功能的测试中运行良好,并且没有 JPA 服务的第一个版本现在正在运行(文件上传、下载和这些东西)。
现在我正在集成 JPA 以应用我们需要的所有功能,但是,即使所有测试工作正常(包括服务测试),当我将 Postman 的请求提交给本地服务器。
这是个例外:
javax.servlet.ServletException: org.glassfish.jersey.server.ContainerException: java.lang.NoClassDefFoundError: javax/persistence/TableGenerators
这是我的 pom.xml

并且在Entity Manager的生成过程中触发异常
em = Persistence.createEntityManagerFactory("testDb").createEntityManager();
JDBC 驱动程序也在 eEntity Manager 实例之前注册
try {
Class.forName("com.mysql.cj.jdbc.Driver");
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
我还使用插件强制检查是否有任何依赖项在我的 pom.xml 中创建任何版本不兼容。
这是我必须从 0 开始配置的第一个项目,这个问题是我解决问题的最后一个资源。
谢谢大家:D
