Hibernate与jpa 2.1 SerialContext不能转换为DataSource

Question

我想让休眠与JPA，glassfish和Java EE7一起工作。但目前我似乎没有任何运气。当我尝试创建EntityManagerFactory时，我经常遇到无法解决的这个错误。

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

应该创建了EntityManager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"> 
    <persistence-unit name="kwetter" transaction-type="JTA"> 
    <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="hibernate.connection.username" value="root"/> 
     <property name="hibernate.connection.password" value=""/> 
     <property name="hibernate.archive.autodetection" value="class"/> 
     <property name="hibernate.show_sql" value="true"/> 
     <property name="hibernate.format_sql" value="true"/> 
     <property name="hbm2ddl.auto" value="update"/> 
     <property name="javax.persistence.schema-generation.database.action" value="drop-and-create"/> 
    </properties> 
    </persistence-unit> 
</persistence> 

而且pom.xml的

<dependency> 
    <groupId>org.hibernate</groupId> 
    <artifactId>hibernate-jpamodelgen</artifactId> 
    <version>5.2.8.Final</version>

看起来问题出在你的persistence.xml作为证明被错误：

javax.persistence.PersistenceException: Unable to build entity manager factory

看你的依赖，你是混合起来的EclipseLink和休眠。两者都是JPA实现。如果我是正确的，Glassfish有eclipselink的默认实现，所以你应该坚持使用它。查看this以获得正确的实施。

如果你真的想使用休眠，请使用org.hibernate.javax.persistence而不是org.eclipselink.persistence的依赖关系。

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