我对 Spring Web Flow 和 Spring Data JPA 比较陌生。我在网上搜索了没有运气，并真诚地希望我能找到帮助。

我正在尝试利用 PersistenceContext 标记将对象保存在流中。当我省略标签时，一切都运行良好，但这不是我的想法，因为我不希望事务提交到流程结束。

当我使用 PersistenceContext 保存时，我得到了一个不知从何而来的失败更新，如控制台所示，

Hibernate: insert into Tb_Horario (DescripcionRestringido, Fase, FechaFin, FechaInicio, FlagReservado, FlagRestringido, HorasTotal, Operador) values (?, ?, ?, ?, ?, ?, ?, ?)
Hibernate: update Tb_Horario set Fase=?, Id=? where id=?

并且因为Id得到了 Identity 自动生成的值，所以我在错误跟踪中得到了 java.sql.SQLException。正如我所说，当我省略persistente 上下文时，我只得到插入但没有阻塞更新。

我提前感谢任何帮助。

这是我的流程：

<persistence-context /> 

<input name="solicitudId" required="true" />

<on-start>
    <evaluate expression="solicitudService.armarSolicitudDTO(solicitudId)" result="flowScope.solicitudDTO" />
</on-start>

<view-state id="programarSolicitud" model="solicitudDTO">   
    <on-render>
        <render fragments="body" />
    </on-render>            
    <transition on="programarFase" to="programarOperador" >
        <set name="viewScope.operadorId" value="currentEvent.attributes.operadorId"/>
        <set name="viewScope.ordenFase" value="currentEvent.attributes.ordenFase"/>                 
        <evaluate expression="operadorService.findById(operadorId)" result="flowScope.operador" />
        <evaluate expression="solicitudDTO.getFases().get(ordenFase)" result="flowScope.fase" />                    
    </transition>
<transition on="programarSolicitud" to="programacionRegistrada"/>       
</view-state>

<view-state id="programarOperador" model="horarioDTO">
    <var name="horarioDTO" class="org.mbcorp.sar.model.Horario"/>
    <on-render>
        <render fragments="body" />
    </on-render>
    <transition on="programarHorario" to="programarSolicitud">
        <evaluate expression="horarioService.save(horarioDTO)" />
    </transition>
</view-state>

<end-state id="programacionRegistrada" commit="true"/>

EDIT2：这里的Horario类

@Entity
@Table(name = "Tb_Horario")
public class Horario implements Serializable{

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;

@Column(name = "HorasTotal", nullable = false)
private Integer horasTotal;

@DateTimeFormat(pattern = "dd-MM-yyyy")
@Column(name = "FechaInicio", nullable = false)
private Date fechaInicio;

@Column(name = "FechaFin", nullable = false)
private Date fechaFin;

@Column(name = "FlagRestringido", nullable = false)
private boolean flagRestringido;

@Column(name = "DescripcionRestringido", nullable = true)
private String descripcionRestringido;

@Column(name = "FlagReservado", nullable = false)
private boolean flagReservado;

@JoinColumn(name = "Operador")
@ManyToOne(optional = false, fetch = FetchType.EAGER)
private Operador operador;

@JoinColumn(name = "Fase")
@ManyToOne(optional = false, fetch = FetchType.EAGER)
private Fase fase;

@Transient
private int horaInicio;

...
//setters and getters
}

和Fase类：

@Entity
@Table(name = "Tb_Fase")
public class Fase implements Serializable{

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;

@Column(name = "Nombre", nullable = false)
private String nombre;

@Column(name = "Descripcion", nullable = false)
private String descripcion;

@Column(name = "FechaRegistro", nullable = false)
private Date fechaRegistro;

@Column(name = "FechaInicio", nullable = true)
private Date fechaInicio;

@Column(name = "FechaFin", nullable = true)
private Date fechaFin;

@Column(name = "Comentarios", nullable = true)
private String comentarios;

@Column(name = "EsfuerzoEstimado", nullable = true)
private Integer esfuerzoEstimado;

@Column(name = "CostoEstimado", nullable = true)
private Integer costoEstimado;

@Column(name = "EsfuerzoReal", nullable = true)
private Integer esfuerzoReal;

@Column(name = "CostoReal", nullable = true)
private Integer costoReal;

@JoinColumn(name = "Solicitud", insertable = false, updatable=false, nullable = false)
@ManyToOne(optional = false, fetch = FetchType.EAGER)
private Solicitud Solicitud;

@OneToMany(fetch = FetchType.EAGER)
@JoinColumn(name = "Fase", nullable = true)
@IndexColumn(name= "Id")
private List<Horario> horarios;

@ManyToMany
@LazyCollection(LazyCollectionOption.FALSE)
@JoinTable(name="tb_CompetenciaFase", joinColumns = {@JoinColumn(name="IdFase")},
           inverseJoinColumns={@JoinColumn(name="IdCompetencia")})
private List<Competencia> competencias;

@Column(name = "RecursosEstimados", nullable = true)
private Integer recursosEstimados;

@Column(name = "OrdenFase", nullable = true)
private Integer ordenFase;

@Transient
private List<Operador> recursosDisponibles;

@Transient
private int recursosUtilizados;

@Transient
private int horasProgramadas;

...
/getters and setters
}

horarioService.save(horarioDTO) 方法只是调用一个从 .save@Service调用 save 方法的类JpaRepository。我对其进行了测试并正在做它的工作，只调用一个INSERT查询。但我完全不知道是什么产生了UPDATE（或者如果它是预期的，为什么工作很奇怪），当<persistence-context/>它出现在流中时出现。

EDIT3：我将 Horario 映射更改为：

@OneToMany(fetch = FetchType.EAGER)
@JoinColumn(name = "Fase", nullable = true)
@IndexColumn(name= "HorasTotal")
private List<Horario> horarios;

并抑制（违背我的意愿）列Fase和HorasTotal. 它现在部分地处理一些奇怪或预期的行为。让我详细说明：

第一个问题：

插入后我仍然得到更新：

Hibernate: insert into Tb_Horario (DescripcionRestringido, Fase, FechaFin, FechaInicio, FlagReservado, FlagRestringido, HorasTotal, Operador) values (?, ?, ?, ?, ?, ?, ?, ?)
Hibernate: update Tb_Horario set Fase=?, HorasTotal=? where id=?

我没有从中得到任何问题Fase，但是 的值HorasTotal正在根据顺序被覆盖，所以我正在考虑创建一个特殊的列来索引表。

第二期：

无论流程结束，即 COMMIT 发生的Horario位置，信息都保存在数据库中。我应用此解决方案将flushMode 设置为COMMIT，但数据COMMIT 与否。

PS：我用缺少的结束状态更新了流程。

您可以在休眠配置中尝试此操作

<property name="org.hibernate.FlushMode" value="commit" />

默认情况下，Hibernate 在 FlushMode AUTO 下运行。这意味着当必须刷新持久性上下文时，休眠将自行决定。通常，当您使用生成的 id 时，Hibernate 通常会决定在持久性上下文中插入新对象时刷新（以便立即获得 Id）。

将其更改为COMMIT将强制休眠等到事务结束。

其他几点说明：

  • 我在您的流程中看不到提交点。根据doc，您必须在流程中添加类似这样的内容：

<end-state id="endStateId" commit="true" />

  • 发布错误跟踪确实可以帮助...

编辑

您的映射中有一些奇怪的东西。您正在使用Id列作为集合的索引。我想这是您问题的根本原因，因为您正在使用纯技术列（pk）来获取业务数据（即订购集合）。

查看此日志的案例：

update Tb_Horario set Fase=?, Id=? where id=?

您可以看到更新的列有一个大写的I，这就是为什么我很确定 hibernate 尝试更新 @IndexColumn... 并且它失败了，因为它也是主键。

因此，我建议您添加一个新列来索引您的收藏。

关于第二个问题：

  • 在流程结束之前仔细检查 horario 是否在您的数据库中（使用第三方数据库客户端）
  • 检查如何在horarioService. （您应该使用@EntityManager没有属性扩展的注释来获取它！！！）

如果在这些检查之后问题得到确认，您可以尝试以下解决方法：

利用 ：

<evaluate expression="persistenceContext.persist(horarioDTO)"/>

代替 ：

<evaluate expression="horarioService.save(horarioDTO)" />

当然，这种变通方法只有在horarioService.save()不执行任何额外业务逻辑（即仅调用persist()）的情况下才可接受。

根据 DTO 后缀，我猜您可能需要在持久化之前将 DTO 转换为实体。希望你能用另一种表达方式做到这一点：类似

<evaluate expression="horarioService.save(horarioDTO.toEntity())" />

第 1 期已解决。

感谢 ben75，我意识到我的映射可能是错误的，所以我更改了Horariofrom 的映射：

@OneToMany(fetch = FetchType.EAGER)
@JoinColumn(name = "Fase", nullable = true)
@IndexColumn(name= "Id")
private List<Horario> horarios;

至

@OneToMany(mappedBy = "fase")
@LazyCollection(LazyCollectionOption.FALSE)
private List<Horario> horarios;

似乎这@IndexColumn是导致问题的原因，所以我将其删除。关于第二个问题，我认为这可能是由于休眠刷新模式或 FlowExecutionListener 支持 Spring data-jpa，因为我使用的是 JpaFlowExecutionListener 而不是 HibernateFlowExecutionListener（我不能使用它，因为我没有 SessionFactory）。
