我有一个名为 Medico 的实体，它是作为数据库中的实体类创建的，因此我认为此处的实体定义是故障安全的，但定义如下:
@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..
}
我想在 MySql 数据库上创建新的 Medico 实体，这就是我这样做的方式:
@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();
}
}
从我的 JSF 页面调用 save() 后，出现以下异常:

我做错了什么？我错过了什么？
如果它有任何用处，这里是我的 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>
</persistence-unit>
最佳答案
异常清楚地表明存在约束验证冲突。我假设您在类中有一个预持久拦截器，它定义了您要保存的 consultedDoctor 的类型。 查看那里并提供有关类类型和预持久拦截器的更多信息，以及 Medico 实体 bean 的映射和约束。
亲切的问候
关于持久化实体时出现 javax.ejb.EJBException，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/6389056/
我正在用Ruby编写一个简单的程序来检查域列表是否被占用。基本上它循环遍历列表，并使用以下函数进行检查。require'rubygems'require'whois'defcheck_domain(domain)c=Whois::Client.newc.query("google.com").available?end程序不断出错(即使我在google.com中进行硬编码)，并打印以下消息。鉴于该程序非常简单，我已经没有什么想法了-有什么建议吗？/Library/Ruby/Gems/1.8/gems/whois-2.0.2/lib/whois/server/adapters/base.

对于Rails模型，是否可以/建议让一个类的成员不持久保存到数据库中？我想将用户最后选择的类型存储在session变量中。由于我无法从我的模型中设置session变量，我想将值存储在一个“虚拟”类成员中，该成员只是将值传递回Controller。你能有这样的类(class)成员吗？ 最佳答案 将非持久属性添加到Rails模型就像任何其他Ruby类一样:classUser扩展解释:在Ruby中，所有实例变量都是私有(private)的，不需要在赋值前定义。attr_accessor创建一个setter和getter方法:classUs
