我正在使用Maven和OpeJPA在Intellij Idea 13中创建一个小型桌面应用程序。我运行应用程序，这打开确定，但是当我使用应用程序搜索cliente数据库时，将启动异常堆栈。
这是persistence.xml中的配置
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="2.0">
<persistence-unit name="sacPU" transaction-type="RESOURCE_LOCAL">

<property name="openjpa.RemoteCommitProvider" value="sjvm"/>
<property name="openjpa.RuntimeUnenhancedClasses" value="supported"/>
</properties>
</persistence-unit>
</persistence>
这是de Cliente class和ClienteDao class
@Table(name = "cliente", catalog = "sac")
@Entity
public class Cliente implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(nullable = false, unique = true)
private Long id;
private String nombre;
private String apellidoPaterno;
private String apellidoMaterno;
private String sexo;
private String run;
private String direccion;
private String comuna;
private Date fechaIngreso;
private int telefono;
private int movil;
private String email;
private String usuario;
private String pass;
@OneToMany(cascade = CascadeType.ALL)
private List<Producto> productos;
/** METHODS **/
}
ClienteDao Class
public class ClienteDao {
private static EntityManager entityManager = Persistencia.getEntityManager();
public static Cliente find(Long id){
return entityManager.find(Cliente.class,id);
}
public static Cliente findByRUN(String rn){
Query q = entityManager.createQuery("select c from Cliente c where c.run=:run");
q.setParameter("run",rn);
if(!q.getResultList().isEmpty()){
List c= q.getResultList();
return (Cliente) c.get(0);
}else{
return null;
}
}
}
持久性等级
public class Persistencia {
private static EntityManager entityManager;
static{
EntityManagerFactory factory = Persistence.createEntityManagerFactory("sacPU");
entityManager = factory.createEntityManager();
}
public static EntityManager getEntityManager() {
return entityManager;
}
}

请不要使用该财产。将其重新设置为unsupported，或将其全部删除。您需要在构建时增强，或使用-javaagent。
