javax.ejb.EJBException异常持久的实体

当我有一个实体，称为医学生这是从数据库创建为一个实体类，所以我认为实体定义为故障保护这里，尽管如此，定义如下：javax.ejb.EJBException异常持久的实体

@Entity 
@Table(name = "medico") 
@XmlRootElement 
@NamedQueries({All named queries here}) 
public class Medico implements Serializable { 
private static final long serialVersionUID = 1L; 
    @Id 
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    @Basic(optional = false) 
    @NotNull 
    @Column(name = "idMedico") 
    private Integer idMedico; 
    @Basic(optional = false) 
    @NotNull 
    @Column(name = "Identificacion") 
    private int identificacion; 
    @Basic(optional = false) 
    @NotNull 
    @Size(min = 1, max = 33) 
    @Column(name = "Primer_Nombre") 
    private String primerNombre; 
    @Size(max = 33) 
    @Column(name = "Segundo_Nombre") 
    private String segundoNombre; 
    @Basic(optional = false) 
    @NotNull 
    @Size(min = 1, max = 33) 
    @Column(name = "Primer_Apellido") 
    private String primerApellido; 
    @Size(max = 33) 
    @Column(name = "Segundo_Apellido") 
    private String segundoApellido; 
    @Basic(optional = false) 
    @NotNull 
    @Column(name = "Telefono") 
    private long telefono; 
    @Column(name = "Telefono_Celular") 
    private BigInteger telefonoCelular; 
    @Basic(optional = false) 
    @NotNull 
    @Size(min = 1, max = 33) 
    @Column(name = "Direccion") 
    private String direccion; 
    // Constructors.. 
    // Getters and setters.. 
}

我想创建MySQL数据库上新医学生实体，而这就是我正在做的这样：

@ManagedBean 
@ViewScoped 
public class ConsultaMedicos implements Serializable { 
// Variables Definition .. 
@EJB 
private DoctorsFacadeLocal doctorsFacade; 
// Constructor and other methods .. 
public String save() 
    { 
     try{ 
      doctorsFacade.save(consultedDoctor); 
      FacesMessage fm = new FacesMessage(FacesMessage.SEVERITY_INFO, CREATE_SUMMARY, null); 
      FacesContext.getCurrentInstance().addMessage(CREATE_SUMMARY, fm); 
     } 
     catch(Exception ex){ 
      FacesMessage fm = new FacesMessage(FacesMessage.SEVERITY_ERROR, CREATE_ERROR_SUMMARY, null); 
      FacesContext.getCurrentInstance().addMessage(CREATE_ERROR_SUMMARY, fm); 
      return null; 
     } 
     return "listaMedicos.xhtml"; 
    } 
... 
} 

@Local 
public interface DoctorsFacadeLocal { 

    List<Medico> findAllDoctors(); 
    Medico findDoctorByIdNumber(int identificacion); 
    void edit(Medico medico); 
    void save(Medico medico); 
} 

@Stateless 
public class DoctorsFacade implements DoctorsFacadeLocal { 

    @PersistenceContext 
    private EntityManager em; 
// Other methods.. 
    @Override 
    @TransactionAttribute(TransactionAttributeType.REQUIRED) 
    public void save(Medico medico) 
    { 
     em.persist(medico); 
     em.flush(); 
    } 
}

我把从我的JSF页面save()后，我得到以下异常：

我在做什么错？我错过了什么？
如果它提供的任何东西我的继承人的persistence.xml

<persistence-unit name="lemmPU" transaction-type="JTA"> 
    <jta-data-source>jdbc/lemmdb</jta-data-source> 
    <exclude-unlisted-classes>false</exclude-unlisted-classes> 
    <properties> 
    </properties>

我可以使用'em.merge'来编辑现有的实体，但是我不能创建这个问题 – camiloqp

异常明确指出，有一个约束验证冲突。我假设你在类中定义了一个预留持续拦截器，它定义了你试图保存的consultedDoctor的类型。 看那里，并提供一些关于类和预留持续拦截器的更多信息，以及Medico实体bean的映射和约束。

亲切的问候

您好，感谢您的回答，我添加了'Medico'的类定义，它是我试图保存的实体。但是，我不知道什么是_pre-persist拦截器，它通常位于何处或定义在哪里？ – camiloqp

+1

好的，因为我怀疑，你有很多验证你的实体bean是好的。您没有特定的PrePersist拦截器。要了解有关PrePersist的更多信息，可以查看@PrePersist注释及其规范。 无论如何，要解决你的问题，你必须检查哪些约束被违反。我敢打赌，你有一个@NotNull注释为空的字段，或者是一个比1或更长的字符或类似的字符串。你可以**调试**你的代码，或者在保存之前直接打印出对象，并且它可以更清楚地知道问题出在哪里。 – peshkira

问题是在实体的主键上设置了@NotNull。删除这个注解并保留所有其他的验证使得坚持不懈的工作成为可能，但却很愚蠢。你指出我要找出问题的方向，所以我马上授予+100。再次感谢 – camiloqp

嗨如果你是在Netbeans的发展，你可以通过一个有点混淆的得到这个错误，因为NetBeans将创建persistence.xml文件的两个副本。其中一个你倾向于在classpath中放入META-INF，另一个留在Netbeans的配置文件目录中。在由Netbeans启动的应用程序（通过按绿色的开始三角形）时，使用了来自META-INF的副本，但是如果您“清理并构建”该项目，则将使用来自Configuration Files目录的副本。如果他们不同，地狱就会松散。

与问题中给出的情况无关。 – Iridann

如果你有一个自动递增Id的实体，并且你想使用它的空构造函数使用JPA来持久它，那么持久性上下文会在PrePersist阶段抛出验证错误。请记住，在postPersist Stage中会生成自动增加的否，因此它会将实体验证为违反null约束。这是因为我们在持久性单元中指定了验证策略为auto。改变这种验证策略为NONE

<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="studPU" transaction-type="JTA"> 
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider> 
    <jta-data-source>jdbc/mysql</jta-data-source> 
    <exclude-unlisted-classes>false</exclude-unlisted-classes> 
    <validation-mode>NONE</validation-mode> 
    <properties> 
    <property name="eclipselink.weaving" value="false"/> 
    <property name="eclipselink.weaving.fetchgroups" value="false"/> 
    </properties> 
    </persistence-unit> 
    </persistence>

下给出保存持久性单元并重新部署应用。现在它不会抛出任何验证错误，因为验证的责任在于你。

这个问题帮我解决了这个问题，经过了太多的时间，我的头撞墙了。 @peshkira是现货，但提供了以下代码，它可能为我节省了一些时间。对实体运行验证以展示失败的约束。

ValidatorFactory factory = Validation.buildDefaultValidatorFactory(); 
Validator validator = factory.getValidator(); 
Set<ConstraintViolation<Medico>> constraintViolations = validator.validate(medico); 
if(constraintViolations.size() > 0){ 
    Iterator<ConstraintViolation<Medico>> iterator = constraintViolations.iterator(); 
    while(iterator.hasNext()){ 
     ConstraintViolation<Medico> cv = iterator.next(); 
     System.out.println(cv.getMessage()); 
     System.out.println(cv.getPropertyPath()); 
    } 
}

我的问题竟然是在数据库中已有记载，后发现无法通过实体验证。

如果上面提供的帮助无法帮助，请检查您的servlet是否在您的jsp页面中获取了正确的参数。

确保String name = response.getParameter（“Name”）; （在servlet文件中）在jsp文件中存在一个参数“Name”。如果不存在，则tring名称设置为null，并且null不能插入标记为非空的字段中。

从个人经验。
