Hibernate with jpa 2.1 SerialContext无法强制转换为DataSource

时间：2017-03-06 21:11:18

标签： hibernate java-ee-7 glassfish-4

我试图让hibernate与JPA，glassfish和Java EE7一起工作。但到目前为止我似乎没有任何运气。当我尝试创建EntityManagerFactory时，我经常遇到这个我无法解决的错误。

java.lang.ClassCastException: com.sun.enterprise.naming.impl.SerialContext cannot be cast to javax.sql.DataSource

应该创建entitymanager的类：

@Singleton
@Startup
public class InitCoffee {

    @PostConstruct
    public void init() {

         EntityManagerFactory emf = Persistence.createEntityManagerFactory("kwetter");
       //EntityManager em = emf.createEntityManager();

        System.out.println("did the init");
    }

}

的persistence.xml 

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://www.oracle.com/webfolder/technetwork/jsc/xml/ns/persistence/persistence_2_1.xsd">

   <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
    <jta-data-source>java:app/kwitter</jta-data-source>
    <properties>
      <property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.SunOneJtaPlatform"/>
      <property name="hibernate.connection.url" value="jdbc:mysql://localhost/kwetter"/>
      <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>

      <property name="hbm2ddl.auto" value="update"/>
      <property name="javax.persistence.schema-generation.database.action" value="drop-and-create"/>
    </properties>
  </persistence-unit>
</persistence>

答案 0 :(得分：0)

问题出现在你的persistence.xml中，正如错误所证明的那样：

  

javax.persistence.PersistenceException：无法构建实体管理器   工厂

查看您的依赖项，您正在混淆eclipselink和hibernate。两者都是JPA实现。如果我是正确的，Glassfish有一个eclipselink的默认实现，所以你应该坚持使用那个。请查看this以获得正确的实施。

如果您真的想使用hibernate，请使用org.hibernate.javax.persistence上的依赖项而不是org.eclipselink.persistence。

此外，可以使用@PersistenceContext注释代替您正在使用的Singleton类。
