NullPointerException从EntityManagerFactory创建EntityManager

时间：2019-03-26 08:11:08

标签： java-ee jboss persistence entitymanager

我已经使用我的persistence.xml中添加的持久性单元成功创建了EntityManagerFactory，但是控制台日志在以这种方式创建EntityManager时显示了异常：

EntityManagerFactory emf;
EntityManager em;
...
emf = Persistence.createEntityManagerFactory("unidadPersistencia");
em = emf.createEntityManager(); //the error is in this line.

该应用可以识别连接和正确的表格。但我无法创建EntityManager。

实体：

@Entity
@Table(name = "CVINSTELEMATICA")
public class SolicitudTelematica extends AbstractEntity{

    private static final long serialVersionUID = 1L;

    @Id
    @NotNull
    @Column(name = "ID")
    private long idTelematica;

    @Column(name = "NUMEROMENORES", columnDefinition = "smallint")
    private int numeroMenores;

    @Column(name = "NIFTUTOR", columnDefinition = "nvarchar")
    private String nifTutor;

Persistence.xml：

<persistence version="2.0" 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">
    <persistence-unit name="unidadPersistencia"  transaction-type="JTA">
        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>  
         <class>es.xunta.amtega.vp301b.entity.SolicitudTelematica</class>
         <properties>
            <property name="javax.persistence.jdbc.driver" value="com.microsoft.sqlserver.jdbc.SQLServerDriver"/>
            <property name="javax.persistence.jdbc.url" value="DB_URL"/> 
            <property name="javax.persistence.jdbc.user" value="usr"/>
            <property name="javax.persistence.jdbc.password" value=pwd/>
         </properties>
    </persistence-unit>
</persistence>

持久性文件或实体中是否可能缺少某些东西？

我认为当您使用JTA作为事务类型时，您必须在JEE环境中，以便容器（在您的情况下为JBoss）将使用注释@PersistenceContext处理实体管理器，但是在这里，您正在处理实体管理器您自己创建实体管理器工厂，而不是在JEE环境中，而是使用Java SE，因此我认为您必须在持久性单元XML中将transaction-type =“ JTA”更改为transaction-type =“ RESOURCE_LOCAL”文件。
