Java Hibernate-没有名为的EntityManager的存在提供程序*

在互联网上浏览并尝试各种解决方案后，我来到这里寻求帮助

我有一个java项目，它在Mac上（部署在本地tomcat上）本地运行得非常好，但是当我尝试在Ubuntu服务器上部署相同的war时，请求抛出500，并带有以下跟踪：

javax.servlet.ServletException: javax.persistence.PersistenceException: No Persistence provider for EntityManager named PERSISTENCE: Provider named org.hibernate.jpa.HibernatePersistenceProvider threw unexpected exception at create EntityManagerFactory: 
java.lang.NoSuchMethodError
java.lang.NoSuchMethodError: javax.persistence.Table.indexes()[Ljavax/persistence/Index;

    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:83)
    at com.frusoft.schedulemanager.databaseaccess.BaseDao.<init>(BaseDao.java:25)
    at com.frusoft.schedulemanager.databaseaccess.ClientDao.<init>(ClientDao.java:11)

这就是我实例化EntityManagerFactory的方式

if (emf == null)
            emf = Persistence.createEntityManagerFactory("PERSISTENCE");

任何形式的帮助都将不胜感激

您必须告诉

JPA

您使用的是哪家JPA提供商

将

org.hibernate.jpa.HibernatePersistenceProvider

添加到

peristence.xml

中的

peristenceUnit

：

<persistence-unit name="PERSISTENCE" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>

    <properties>
        ...
    </properties>
</persistence-unit>

org.hibernate.jpa.HibernatePersistenceProvider
...

问题在于

    <dependency>
        <groupId>javax.persistence</groupId>
        <artifactId>persistence-api</artifactId>
        <version>1.0.2</version>
    </dependency>

javax.persistence
持久性api
1.0.2

正在被hibernate覆盖。 我需要删除依赖项或设置与hibernate 5.x兼容的较新依赖项

    <dependency>
        <groupId>javax.persistence</groupId>
        <artifactId>javax.persistence-api</artifactId>
        <version>2.2</version>
    </dependency>

javax.persistence
javax.persistence-api
2.2

在执行

mvn安装之前，我还需要抛出
mvn clean
命令，以生成.war，从而不再缓存依赖项

----------注---------

我仍然不清楚为什么这在我的本地机器（我在那里开发了这个后端）上能正常工作。
看看这是否能帮助你：就是这样！我记得我以前试过，但没有成功。问题是，我需要在安装mvn之前执行mvn清理！在显式添加提供程序之后（尽管不需要），它仍然显示完全相同的错误。不过，这只发生在我拥有的Ubuntu VPS上，在本地运行很好！
