org.hibernate.PersistentObjectException：獨立實體被persist：com.horariolivre.entity.Key

在我的春天應用程序，我想在數據庫中持久後續實體：org.hibernate.PersistentObjectException：獨立實體被persist：com.horariolivre.entity.Key

@Entity 
@Table(name = "usuario") 
public class Usuario implements java.io.Serializable { 

    private static final long serialVersionUID = -7283129128268761582L;

    public Usuario(String login, String senha, String primeiroNome, String ultimoNome, Tipo tipo, List<Atributo> atributos) {

     this.atributo = atributos; 
     this.config = new ConfigHorarioLivre(); 
     this.autorizacao = new ArrayList<Autorizacao>(); 
    } 

    @Id 
    @Column(name = "id", unique = true, nullable = false) 
    @GeneratedValue(strategy=GenerationType.AUTO)

    @OneToOne(cascade=CascadeType.ALL, fetch=FetchType.EAGER) 
    @JoinColumn(name="fk_tipo") 
    public Tipo getTipo() { 
     return tipo; 
    } 

    public void setTipo(Tipo tipo) { 
     this.tipo = tipo; 
    } 

    @OneToMany(cascade=CascadeType.ALL) 
    @JoinTable(name="atributo_usuario", joinColumns={@JoinColumn(name="fk_usuario")}, inverseJoinColumns={@JoinColumn(name="fk_atributo")}) 
    @LazyCollection(LazyCollectionOption.FALSE) 
    public List<Atributo> getAtributo() { 
     return atributo; 
    } 

    public void setAtributo(List<Atributo> atributo) { 
     this.atributo = atributo; 
    } 

    @OneToOne(cascade=CascadeType.ALL) 
    @JoinColumn(name="fk_config") 
    public ConfigHorarioLivre getConfig() {

    public void setConfig(ConfigHorarioLivre config) {

    } 

    @OneToMany(cascade=CascadeType.ALL)

    } 

    public void setAutorizacao(List<Autorizacao> autorizacao) { 
     this.autorizacao = autorizacao; 
    } 

}

而且我現在面臨這個錯誤：

    public void setKey(Key key) { 
     this.key = key; 
    } 

    @OneToOne(cascade=CascadeType.ALL, fetch=FetchType.EAGER) 
    @JoinColumn(name="value") 
    public Value getValue() { 
     return value; 
    } 

    public void setValue(Value value) { 
     this.value = value; 
    } 

}

節約運關合作是這樣處理的：

public boolean cadastra(String login, String senha, String primeiroNome, String ultimoNome, String tipoUsuario, String[] campo, String[] valor) { 
    Tipo tipo_usuario = tipo.findByNome(tipoUsuario); 
    List<Atributo> lista_atributos = new ArrayList<Atributo>(); 

    for(int i=0; i<campo.length; i++) { 
     Key chave = key.findByNome(campo[i]); 
     Value conteudo = new Value(valor[i]); 
     value.persist(conteudo); 
     lista_atributos.add(new Atributo(chave, conteudo)); 
     atributo.persist(lista_atributos.get(i)); 
    } 

    return this.usuario.persist(new Usuario(login, senha, primeiroNome, ultimoNome, tipo_usuario, lista_atributos)); 
}

有人能方向指向堅持這個實體的正確方法？

看http://stackoverflow.com/questions/18345598/hibernate-manytoone-only-works-with-cascadetype-all/18345715#18345715 –

你如何保存這些entites的？發佈你的代碼。最有可能的是你創建新的對象，然後通過級聯保存多個時間。 – Angga

我用請求的代碼更新了問題？有任何想法嗎？ –

我終於解決了這個問題。讓我分享這個操作中主要參與者的最終代碼：Usuario.java/Atributo.java和Key/Value。簡而言之，這是關於Atributo類的@Cascade(org.hibernate.annotations.CascadeType.SAVE_UPDATE)和Usuario類的fetch=FetchType.LAZY的組合。

您仍然在服務層中使用分離的實體。也許改變級聯策略有助於這種特殊情況，但設計很容易出錯。另一個問題（更大的問題）是，您將每個實體都保存在單獨的事務中（出於同樣的原因：因爲trx邊界位於DAO上，而不是服務層上）。這可能會導致嚴重的數據完整性問題，以防您在服務方法中出現異常。 – gadget

實際上，在我的項目的當前狀態中，來自Service類的訪問數據庫的方法具有註釋@Transactional。請參閱https://github.com/klebermo/webapp_horario_livre/tree/master/src/com/horariolivre/service –

啊，所以你在任何地方都添加了@Transactional，事實並非如此。這應該已經解決了您的原始問題，而無需更改級聯策略... – gadget

你的服務的方法不是事務性的。您的交易在每個DAO方法之前打開並承諾。由於hibernate會話連接到當前事務，因此會話在從DAO方法返回後始終關閉。這會導致服務層中的分離實體。快速修復只需添加@Transactional到您的服務方法：

@Transactional 
public boolean cadastra(String login, String senha, String primeiroNome, String ultimoNome, String tipoUsuario, String[] campo, String[] valor) { 
... 
}
