NullPointerException 从 EntityManagerFactory 创建 EntityManager
NullPointerException creating EntityManager from EntityManagerFactory
我已经成功创建了一个 EntityManagerFactory，使用我 persistence.xml 中添加的持久化单元，但控制台日志显示以这种方式创建 EntityManager 时出现异常：
EntityManagerFactory emf;
EntityManager em;
...
emf = Persistence.createEntityManagerFactory("unidadPersistencia");
em = emf.createEntityManager(); //the error is in this line.
应用程序识别连接并正确table。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:

我正在使用 JBoss EAP 6.1 和 Java 7.
我认为当您使用 JTA 作为事务类型时，您必须处于 JEE 环境中，这样容器（JBoss，在您的情况下）将使用注释 @PersistenceContext 处理实体管理器, 但是这里你自己处理实体管理器，创建实体管理器工厂，你不是在 JEE 环境中，你只是在使用 Java SE，所以我认为你必须将 transaction-type="JTA" 更改为 transaction-type="RESOURCE_LOCAL" 在你的持久化单元 XML 文件中。
我已经成功创建了一个 EntityManagerFactory，使用我 persistence.xml 中添加的持久化单元，但控制台日志显示以这种方式创建 EntityManager 时出现异常：
EntityManagerFactory emf;
EntityManager em;
...
emf = Persistence.createEntityManagerFactory("unidadPersistencia");
em = emf.createEntityManager(); //the error is in this line.
应用程序识别连接并正确table。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;

我正在使用 JBoss EAP 6.1 和 Java 7.
我认为当您使用 JTA 作为事务类型时，您必须处于 JEE 环境中，这样容器（JBoss，在您的情况下）将使用注释 @PersistenceContext 处理实体管理器, 但是这里你自己处理实体管理器，创建实体管理器工厂，你不是在 JEE 环境中，你只是在使用 Java SE，所以我认为你必须将 transaction-type="JTA" 更改为 transaction-type="RESOURCE_LOCAL" 在你的持久化单元 XML 文件中。
