Question

Wildfly 9.0.2.Final上的Deltaspike Ver 1.7.2

我在实体bean上使用JPA @EntityListeners(AuditEntityListener.class)和Deltaspike Data（@CreatedOn，@ModifiedOn和@ModifiedBy注释）的审核功能，区别在于拥有java.time.ChronoLocalDateTime的自定义实现，可将LocalDateTime + ZoneOffset或ZonedDateTime转换为UTC日期＆amp;时间。

UTCDateTime

public class UTCDateTime implements ChronoLocalDateTime<LocalDate>, Serializable {

  private static final long serialVersionUID = 6492792765662073566L;
  private static final ZoneOffset UTC = ZoneOffset.UTC;
  private final LocalDateTime datetime;

  // a lot of other details left out
}

实体bean部分

@MappedSuperclass
public class InsertableAuditableBean extends BaseBean implements InsertableAuditable {

  @NotNull
  @Size(min = 1, max = 50)
  @Column(name = "zz_inserted_by", length = 50, nullable = false)
  private String insertedBy;

  @CreatedOn
  @NotNull
  @Temporal(value = TemporalType.TIMESTAMP)
  @Column(name = "zz_inserted_on", nullable = false)
  private UTCDateTime insertedOn;

  // getters & setters
}

@MappedSuperclass
public class UpdateableAuditableBean extends InsertableAuditableBean implements UpdateableAuditable {

  @ModifiedBy
  @Size(min = 1, max = 50)
  @Column(name = "zz_updated_by", length = 50, nullable = true)
  private String updatedBy;

  @ModifiedOn
  @Temporal(value = TemporalType.TIMESTAMP)
  @Column(name = "zz_updated_on", nullable = true)
  private UTCDateTime updatedOn;

  // getters & setters
}

@Entity
@EntityListeners(AuditEntityListener.class)
@Table(schema = "data", name = "manufacturer", uniqueConstraints = {
    @UniqueConstraint(columnNames = { "man_name", "man_country" })
})
@AttributeOverrides({
    @AttributeOverride(name = "primaryKey", column = @Column(name = "man_serial")),
    @AttributeOverride(name = "insertedBy", column = @Column(name = "man_inserted_by")),
    @AttributeOverride(name = "insertedOn", column = @Column(name = "man_inserted_on")),
    @AttributeOverride(name = "updatedBy", column = @Column(name = "man_updated_by")),
    @AttributeOverride(name = "updatedOn", column = @Column(name = "man_updated_on"))
})
@SequenceGenerator(name = "default_seq", schema = "data", sequenceName = "manufacturer_man_serial_seq",
    allocationSize = 1)
public class Manufacturer extends MirroredUpdateableAuditableBean implements IManufacturer {
  // nothing special here
}

UTCDateTime类还有一个自定义AttributeConverter，因为epoch值保存在数据库中。

@Converter(autoApply = true)
public class UTCDateTimePersistenceConverter implements AttributeConverter<UTCDateTime, Long> {

  @Override
  public Long convertToDatabaseColumn(final UTCDateTime entityValue) {
    Long res = null;
    if (entityValue != null) {
      res = entityValue.toMillis();
    }
    return res;
  }

  @Override
  public UTCDateTime convertToEntityAttribute(final Long databaseValue) {
    UTCDateTime res = null;
    if (databaseValue != null) {
      res = new UTCDateTime(Instant.ofEpochMilli(databaseValue));
    }
    return res;
  }
}

现在，当我坚持实体时，我得到以下异常（最后一位有真正的原因）：

Caused by: org.apache.deltaspike.data.api.QueryInvocationException: Failed calling Repository: [Repository=systems.apace.data.manufacturer.model.dao.ManufacturerDAO,entity=systems.apace.data.manufacturer.model.Manufacturer,method=persist,exception=class java.lang.reflect.InvocationTargetException,message=null

        at systems.apace.data.manufacturer.services.ManufacturerServiceBeanIntegrationTest.testInsertBean(ManufacturerServiceBeanIntegrationTest.java:55)

有没有办法实现我自己的org.apache.deltaspike.data.impl.audit.PrePersistAuditListener和org.apache.deltaspike.data.impl.audit.PreUpdateAuditListener并使用它们来创建UTCDateTime的实例？

编写自己的EntityListener是否正确 - ＆gt; UTCDateTimeAuditListener并使用@EntityListeners(UTCDateTimeAuditEntityListener.class)，其中UTCDateTimeAuditListener遵循org.apache.deltaspike.data.impl.audit.AuditEntityListener方法？

其次，我是否需要在某处使用CDI限定符，以确保我的UTCDateTimeAuditEntityListener获得对知道如何构造{{PrePersistAuditListener和PreUpdateAuditListener实现的正确引用的引用1}}实例？

最后，我不知道它是否相关，但UTCDateTime适合这种情况？

更新

我在回答我的问题方面取得了一些进展。到目前为止我做了什么。没有必要使用DeltaSpike提供的自定义org.apache.deltaspike.data.impl.audit.TimestampsProvider就足够了。

我创建了一个AuditEntityListener的新实现，它能够处理我的TimestampsProvider个对象。

UTCDateTime

beans.xml还将此列为CDI @Alternative

@Alternative
@Dependent
public class UTCDateTimeAuditProvider implements PrePersistAuditListener, PreUpdateAuditListener {
  // implementation details not important
}

<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd" version="1.1" bean-discovery-mode="annotated"> <alternatives> <class>systems.apace.data.manufacturer.model.UTCDateTimeAuditProvider</class> </alternatives> </beans>

的内容

apache-deltaspike.properties

现在的问题是两个globalAlternatives.org.apache.deltaspike.jpa.spi.transaction.TransactionStrategy=org.apache.deltaspike.jpa.impl.transaction.ContainerManagedTransactionStrategy个实例都已执行，首先是我的实现（AuditProvider），然后是默认的UTCDateTimeAuditProvider

TimestampsProvider

我尝试过各种组合，只用注释来指定我的@Alternative实现，或者仅在beans.xml中指定我的@Alternative实现，并且在类和＆amp;在beans.xml。

有人知道为什么在@Alternative实现后执行默认2016-12-13 01:29:22,929 INFO Apace-BPS s.a.d.m.m.UTCDateTimeAuditProvider [ServerService Thread Pool -- 319] [Unknown Id] - prePersist: class systems.apace.data.manufacturer.model.UTCDateTimeAuditProvider 2016-12-13 01:29:22,931 INFO Apace-BPS s.a.d.m.m.UTCDateTimeAuditProvider [ServerService Thread Pool -- 319] [Unknown Id] - Updated property Manufacturer.insertedOn with 2016-12-12T23:29:22.930 2016-12-13 01:29:22,932 INFO Apace-BPS z.c.t.c.b.e.EntityManagerProducer [ServerService Thread Pool -- 319] [Unknown Id] - username of Principal: anonymous 2016-12-13 01:29:22,932 FINER [org.apache.deltaspike.data.impl.audit.AuditProvider] (ServerService Thread Pool -- 319) Updated Manufacturer.updatedBy with anonymous 2016-12-13 01:29:22,935 ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 319) MSC000001: Failed to start service jboss.deployment.subunit."bpsserver.ear"."systems-apace-data-model-1.0-SNAPSHOT.jar".component.ManufacturerSi ngleton.START: org.jboss.msc.service.StartException in service jboss.deployment.subunit."bpsserver.ear"."systems-apace-data-model-1.0-SNAPSHOT.jar".component.ManufacturerSingleton.START: java.lang.IllegalStateException: WFLYEE0042: Failed to construct component instance at org.jboss.as.ee.component.ComponentStartService$1.run(ComponentStartService.java:57) ...

Deltaspike Ver 1.7.2 on Wildfly 9.0.2.Final with Weld 2.2.16（SP1）

Answer 1

Deltaspike数据审核不支持Java 8日期和时间API。您可以将@ PrePersist，@ PreUpdate方法与Deltaspike @ModifiedBy字段组合为所有可审核实体的一个共同祖先（好处：不需要获取主体名称的自定义方式）。

Deltaspike Data（CDI + JPA）自定义PrePersistAuditListener和PreUpdateAuditListener，用于UTC的自定义java.time.ChronoLocalDateTime

UTCDateTime
