审核表上的Java Hibernate Envers更新跟踪策略警告HH000416

大家好，我们有一个运行Hibernate的服务器，这些类是用envers审计的。 像这样：

package db.shared;

import interfaces.GuiEditableTable;
import interfaces.ListableEntity;
import interfaces.ShortDescriptable;

import java.util.HashSet;
import java.util.Set;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.Table;
import javax.persistence.UniqueConstraint;
import javax.persistence.Version;

import org.hibernate.annotations.Cache;
import org.hibernate.annotations.CacheConcurrencyStrategy;
import org.hibernate.annotations.Cascade;
import org.hibernate.annotations.CascadeType;
import org.hibernate.envers.AuditTable;
import org.hibernate.envers.Audited;

import common.Identifiable;
import common.Preferences;
import common.entity.EntityConcurrency;

@Entity
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
@Audited
@AuditTable(schema=Preferences.SCHEMA_AUDIT, value=Lizenz.CLASS_NAME+Preferences.AUDIT_SUFFIX)
@Table(schema = Preferences.SCHEMA_SHARED, uniqueConstraints = { @UniqueConstraint(columnNames = { Lizenz.PROPERTY_LIZENZ_NAME }), @UniqueConstraint(columnNames = { Lizenz.PROPERTY_LIZENZ_NUMBER }) })
public class Lizenz extends common.entity.AbstractEntity
implements EntityConcurrency, ListableEntity, ShortDescriptable, GuiEditableTable
{

private static final long serialVersionUID = 589201271279697573L;
public static final String CLASS_NAME = "Lizenz";
public static final String PROPERTY_LIZENZ_NAME = "lizenzName";
public static final String PROPERTY_LIZENZ_NUMBER = "lizenzNummer";
public static final String MTM_PROPERTY_NAME = "lizenz";

public static final int LIZENZ_NUMBER_PADDING = 4;



@Id
@Column(name = Identifiable.PROPERTY_ID, columnDefinition = Preferences.DDL_TYPE_ID)
@GeneratedValue(strategy = GenerationType.IDENTITY)
private long ID;

@Version @Column(name = EntityConcurrency.PROPERTY_VERSION)
private long version;


private String lizenzName;
private String logo;

}

在serverstart上有如下警告：

15:14:49 WARN  [org.hibernate.dialect.lock.UpdateLockingStrategy] HHH000416: Write locks via update not supported for non-versioned entities [db.shared.Lizenz_AUD]
15:14:49 WARN  [org.hibernate.dialect.lock.UpdateLockingStrategy] HHH000416: Write locks via update not supported for non-versioned entities [db.shared.Lizenz_AUD]
15:14:49 WARN  [org.hibernate.dialect.lock.UpdateLockingStrategy] HHH000416: Write locks via update not supported for non-versioned entities [db.shared.Lizenz_AUD]
15:14:49 WARN  [org.hibernate.dialect.lock.PessimisticReadUpdateLockingStrategy] HHH000416: Write locks via update not supported for non-versioned entities [db.shared.Lizenz_AUD]
15:14:49 WARN  [org.hibernate.dialect.lock.PessimisticWriteUpdateLockingStrategy] HHH000416: Write locks via update not supported for non-versioned entities [db.shared.Lizenz_AUD]

问题是我们只为审计创建了DB表，没有任何审计类。这些类将在启动时生成，我们还没有找到任何@audit选项来抑制这些警告。这些警告与我们无关，因为只写一次审核条目，从不更新，每个类有5个警告充斥着我们的日志

我们在Java1.7中使用hibernate-envers-4.1.10.Final.jar和hibernate-core-4.1.10.Final.jar

是否有人有相同的问题或知道如何解决。

我们非常感谢您的帮助。

我们可以在hibernate的源代码中看到：

public UpdateLockingStrategy(Lockable lockable, LockMode lockMode) {

    this.lockable = lockable;

    this.lockMode = lockMode;

    if (lockMode.lessThan(LockMode.UPGRADE)) {

        throw new HibernateException("[" + lockMode + "] not valid for update statement");

    }

    if (!lockable.isVersioned()) {

        log.warn("write locks via update not supported for non-versioned entities [" + lockable.getEntityName() + "]");

        this.sql = null;

    } else {
        this.sql = generateLockString();

    }
}

以及isVersioned（）的文档：

/**
*确定是否为此启用按列的乐观锁定
*实体。
*
*@如果按列进行乐观锁定（即，或
*）已启用；否则就错了。
*/
公共布尔值已版本化（）；

---

其结果是，如果您想使用审计实体，而不发出此警告，您应该在实体的列上启用@Version乐观锁定（：）

问题是如何做到这一点，因为我们没有审计对象，只有表。该对象由Hibernate.Envers在启动时生成。

/**
 * Determine whether optimistic locking by column is enabled for this
 * entity.
 *
 * @return True if optimistic locking by column (i.e., <version/> or
 * <timestamp/>) is enabled; false otherwise.
 */
public boolean isVersioned();
