Java 即使提供了正确的提供程序，也会出现有关PersistenceProvider的Hibernate警告

当我尝试将Hibernate与本地Derby数据库一起使用时，我总是收到关于错误持久性提供程序的三次警告：

[WARN] HHH015016: Encountered a deprecated javax.persistence.spi.PersistenceProvider [org.hibernate.ejb.HibernatePersistence]; use [org.hibernate.jpa.HibernatePersistenceProvider] instead.
[WARN] HHH015016: Encountered a deprecated javax.persistence.spi.PersistenceProvider [org.hibernate.ejb.HibernatePersistence]; use [org.hibernate.jpa.HibernatePersistenceProvider] instead.
[WARN] HHH015016: Encountered a deprecated javax.persistence.spi.PersistenceProvider [org.hibernate.ejb.HibernatePersistence]; use [org.hibernate.jpa.HibernatePersistenceProvider] instead.

我找不到任何原因，因为我的persistence.xml（项目中唯一的persistence.xml）如下所示：

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
    version="2.0">
    <persistence-unit name="performanzdb" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
        <class>...</class>
        <properties>
            <property name="hibernate.connection.url" value="myUrl;create=true" />
            <property name="hibernate.connection.driver_class" value="org.apache.derby.jdbc.EmbeddedDriver" />
            <property name="hibernate.dialect" value="org.hibernate.dialect.DerbyDialect" />
            <property name="hibernate.hbm2ddl.auto" value="update" />
        </properties>
    </persistence-unit>
</persistence>

除了开头的警告和错误之外：

[ERROR] HHH015011: Unable to locate static metamodel field : package.class_#field

Hibernate不时出现在新定义的字段中，运行良好，所有内容都按其应有的方式写入数据库

是否有人知道为什么使用了错误的

PersistenceProvider

，或者为什么会发生此错误？

已报告类似问题，请查看

从以上链接中,

This bug also affects version 4.3.7.Final.

有了一个新的基于maven的Spring引导项目，包括JPA依赖项，当slf4j级别为INFO时，我仍然可以看到这些警告日志行

14:04:47.990 [main] WARN o.hibernate.ejb.HibernatePersistence - HHH015016: Encountered a deprecated javax.persistence.spi.PersistenceProvider [org.hibernate.ejb.HibernatePersistence]; use [org.hibernate.jpa.HibernatePersistenceProvider] instead. 14:04:47.990 [main] WARN o.hibernate.ejb.HibernatePersistence - HHH015016: Encountered a deprecated javax.persistence.spi.PersistenceProvider [org.hibernate.ejb.HibernatePersistence]; use [org.hibernate.jpa.HibernatePersistenceProvider] instead. 14:04:47.990 [main] WARN o.hibernate.ejb.HibernatePersistence - HHH015016: Encountered a deprecated javax.persistence.spi.PersistenceProvider [org.hibernate.ejb.HibernatePersistence]; use [org.hibernate.jpa.HibernatePersistenceProvider] instead. 14:04:47.990[main]WARN o.hibernate.ejb.HibernatePersistence-HHH015016:遇到不推荐的javax.persistence.spi.PersistenceProvider[org.hibernate.ejb.HibernatePersistence]；改用[org.hibernate.jpa.HibernatePersistenceProvider]。 14:04:47.990[main]WARN o.hibernate.ejb.HibernatePersistence-HHH015016:遇到不推荐的javax.persistence.spi.PersistenceProvider[org.hibernate.ejb.HibernatePersistence]；改用[org.hibernate.jpa.HibernatePersistenceProvider]。 14:04:47.990[main]WARN o.hibernate.ejb.HibernatePersistence-HHH015016:遇到不推荐的javax.persistence.spi.PersistenceProvider[org.hibernate.ejb.HibernatePersistence]；改用[org.hibernate.jpa.HibernatePersistenceProvider]。 我找到了此解决方案，并在创建实体管理器工厂之前添加了一段代码：

public EntityManager create() {
    if (AbstractBaseForJUnit.EMF == null) {
        PersistenceProviderResolverHolder.setPersistenceProviderResolver(new PersistenceProviderResolver() {
            private final List<PersistenceProvider> providers_ = Arrays.asList((PersistenceProvider) new HibernatePersistenceProvider());

            @Override
            public void clearCachedProviders() {
                // TODO Auto-generated method stub
            }

            @Override
            public List<PersistenceProvider> getPersistenceProviders() { 
                return providers_; 
            }
        });

        if (StringUtils.isBlank(AbstractBaseForJUnit.PU_NAME)) {
            AbstractBaseForJUnit.PU_NAME = CoreProperties.Features.PERSISTENCE_UNIT_NAME;
        }
        AbstractBaseForJUnit.EMF = Persistence.createEntityManagerFactory(AbstractBaseForJUnit.PU_NAME);
    }

    if (this.EM == null) {
        this.EM = AbstractBaseForJUnit.EMF.createEntityManager();
        this.EM.setFlushMode(FlushModeType.COMMIT);
    }

    return EM;
}

public EntityManager create（）{
if（AbstractBaseForJUnit.EMF==null）{
PersistenceProviderResolver.setPersistenceProviderResolver（新的PersistenceProviderResolver（））{
私有最终列表提供程序=array.asList（（PersistenceProvider）新的HibernatePersistenceProvider（））；
@凌驾
public void clearCachedProviders（）{
//TODO自动生成的方法存根
}
@凌驾
公共列表getPersistenceProviders（）{
退货供应商；
}
});
if（StringUtils.isBlank（AbstractBaseForJUnit.PU_NAME））{
AbstractBaseForJUnit.PU_NAME=CoreProperties.Features.PERSISTENCE_单元名称；
}
AbstractBaseForJUnit.EMF=Persistence.createEntityManagerFactory（AbstractBaseForJUnit.PU_名称）；
}
if（this.EM==null）{
this.EM=AbstractBaseForJUnit.EMF.createEntityManager（）；
this.EM.setFlushMode（FlushModeType.COMMIT）；
}
返回EM；
}

还更改了我的persistence.xml

org.hibernate.jpa.HibernatePersistenceProvider

现在不再显示警告。

请看一看，谢谢，通过在

PersistenceProviderResolverHolder

中设置持久性提供程序，警告不再显示。因此，静态元模型字段出现错误是因为，并且与持久性提供程序无关？是的，不太清楚，只是发布了一个带有类似链接的答案，供您接受/投票。

public EntityManager create() {
    if (AbstractBaseForJUnit.EMF == null) {
        PersistenceProviderResolverHolder.setPersistenceProviderResolver(new PersistenceProviderResolver() {
            private final List<PersistenceProvider> providers_ = Arrays.asList((PersistenceProvider) new HibernatePersistenceProvider());

            @Override
            public void clearCachedProviders() {
                // TODO Auto-generated method stub
            }

            @Override
            public List<PersistenceProvider> getPersistenceProviders() { 
                return providers_; 
            }
        });

        if (StringUtils.isBlank(AbstractBaseForJUnit.PU_NAME)) {
            AbstractBaseForJUnit.PU_NAME = CoreProperties.Features.PERSISTENCE_UNIT_NAME;
        }
        AbstractBaseForJUnit.EMF = Persistence.createEntityManagerFactory(AbstractBaseForJUnit.PU_NAME);
    }

    if (this.EM == null) {
        this.EM = AbstractBaseForJUnit.EMF.createEntityManager();
        this.EM.setFlushMode(FlushModeType.COMMIT);
    }

    return EM;
}
