Question

在我的spring应用程序中，我正在尝试在数据库中保留以下实体：

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

    private static final long serialVersionUID = -7283129128268761582L;

    private int id;
    private String login;
    private String senha;
    private String primeiroNome;
    private String ultimoNome;
    private Tipo tipo;
    private List<Atributo> atributo;
    private ConfigHorarioLivre config;
    private List<Autorizacao> autorizacao;

    public Usuario() {
    }

    public Usuario(String login, String senha) {
        this.setLogin(login);
        this.setSenha(senha);
    }

    public Usuario(String login, String senha, String primeiroNome, String ultimoNome, Tipo tipo, List<Atributo> atributos) {
        this.setLogin(login);
        this.setSenha(senha);
        this.setPrimeiroNome(primeiroNome);
        this.setUltimoNome(ultimoNome);
        this.tipo = tipo;
        this.atributo = atributos;
        this.config = new ConfigHorarioLivre();
        this.autorizacao = new ArrayList<Autorizacao>();
    }

    @Id
    @Column(name = "id", unique = true, nullable = false)
    @GeneratedValue(strategy=GenerationType.AUTO)
    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    @Column(name = "login")
    public String getLogin() {
        return login;
    }

    public void setLogin(String login) {
        this.login = login;
    }

    @Column(name = "senha")
    public String getSenha() {
        return senha;
    }

    public void setSenha(String senha) {
        this.senha = senha;
    }

    @Column(name = "primeiro_nome")
    public String getPrimeiroNome() {
        return primeiroNome;
    }

    public void setPrimeiroNome(String primeiroNome) {
        this.primeiroNome = primeiroNome;
    }

    @Column(name = "ultimo_nome")
    public String getUltimoNome() {
        return ultimoNome;
    }

    public void setUltimoNome(String ultimoNome) {
        this.ultimoNome = ultimoNome;
    }

    @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() {
        return config;
    }

    public void setConfig(ConfigHorarioLivre config) {
        this.config = config;
    }

    @OneToMany(cascade=CascadeType.ALL)
    @JoinTable(name="autorizacao_usuario", joinColumns={@JoinColumn(name="fk_usuario")}, inverseJoinColumns={@JoinColumn(name="fk_autorizacao")})
    @LazyCollection(LazyCollectionOption.FALSE)
    public List<Autorizacao> getAutorizacao() {
        return autorizacao;
    }

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

}

我正面临这个错误：

该atribute Key位于Atributo类中：

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

    private static final long serialVersionUID = 6084758898903241369L;

    private int id;
    private Key key;
    private Value value;

    public Atributo() {
    }

    public Atributo(Key key, Value value) {
        this.key = key;
        this.value = value;
    }

    public Atributo(String key, String value) {
        this.key = new Key(key);
        this.value = new Value(value);
    }

    @Id
    @Column(name = "id")
    @GeneratedValue(strategy=GenerationType.AUTO)
    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    @OneToOne(cascade=CascadeType.ALL, fetch=FetchType.EAGER)
    @JoinColumn(name="key")
    public Key getKey() {
        return key;
    }

    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;
    }

}

保存操作以这种方式处理：

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));
}

有人可以指出正确的方向来坚持这个实体吗？

Answer 1

您的服务方式不是交易方式。您的事务在每个DAO方法之前打开并在之后提交。由于hibernate会话附加到当前事务，因此从DAO方法返回后，会话始终处于关闭状态。这会导致服务层中的分离实体。要快速修复，只需将@Transactional添加到您的服务方法中：

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

Answer 2

我终于解决了这个问题。让我在这里分享一下这个操作中主要参与者的最终代码：Usuario.java / Atributo.java和Key / Value。简而言之，它就是在类Atributo上使用@Cascade(org.hibernate.annotations.CascadeType.SAVE_UPDATE)和在Usuario类上使用fetch=FetchType.LAZY的组合。

<强> Usuario.java

@Entity
@Table(name = "usuario")
