休眠，JPA不能坚持到数据库

我想用JPA和休眠写一个实体到数据库。我没有得到任何例外，但实体没有到达数据库。从数据库获取数据是没有问题的。我使用glassfish 4和Maven。这里是我的代码：休眠，JPA不能坚持到数据库

@LocalBean 
@Stateless 
public class UserEjb { 

    @PersistenceContext(unitName = "JavaEE_JPA_3", type= PersistenceContextType.TRANSACTION) 
    EntityManager em; 

    @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW) 
    public void saveEmployee(EmployeesEntity employee) { 
     em.merge(employee); 
    } 

    public void deleteEmployee(EmployeesEntity employee) { 
     //em.remove(employee); 
    } 
    public EmployeesEntity getEntity() { 
     EmployeesEntity employee = em.find(EmployeesEntity.class, 1); 
     return employee; 
    }

的persistence.xml

<?xml version="1.0" encoding="UTF-8"?> 
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="2.0"> 
    <persistence-unit name="JavaEE_JPA_3"> 
     <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider> 
     <jta-data-source>jdbc/test</jta-data-source> 
     <class>entities.EmployeesEntity</class> 
    </persistence-unit> 
</persistence>

的hibernate.cfg.xml

<?xml version='1.0' encoding='utf-8'?> 
<!DOCTYPE hibernate-configuration PUBLIC 
     "-//Hibernate/Hibernate Configuration DTD//EN" 
     "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> 
<hibernate-configuration> 
    <session-factory> 
    <property name="connection.url">jdbc:mysql://localhost:3306/test</property> 
    <property name="connection.driver_class">com.mysql.jdbc.Driver</property> 
    <property name="hbm2ddl.auto">update</property> 
    <mapping class="entities.EmployeesEntity"/> 
    </session-factory> 
</hibernate-configuration>

如果我以后使用em.flush（）方法提交我的更改我得到以下例外：

如果我尝试做这样的事情：

em.getTransaction().begin(); 
em.persist(employee); 
em.getTransaction().commit();

我得到以下异常：

为什么发布一些“hibernate.cfg”文件？如果您正在使用JPA，那么不会使用它。持久性单元（由JPA使用）正在使用JTA数据源，那么为什么你会得到这个消息让你感到惊讶？ –

尝试TransactionAttributeType.REQUIRED来代替TransactionAttributeType.REQUIRES_NEW –

@Tarun已经尝试过，没有幸运地运行：（ – Snerps

我不能肯定，但我相信你需要获得一个会话，然后在会话对象上调用beginTransaction（）。

然后您可以.commit（）事务。

How can i get the session object if i have the entitymanager

Transaction tx = session.beginTransaction() 
//manipulate your entity 
tx.commit()

感谢您的回答。但是如果我这样做，我会得到以下异常：java.lang.IllegalStateException：JTA EntityManager不能使用getTransaction（） – Snerps

是，你需要从会话对象 –

+0

获取事务如果正在使用JPA，没有“会话”的需求永远是“得到” –
