无法持久化数据实体，提交事务时出错

Question

我成功地编写了部署扩展和存储扩展。

以下是我从核心日志中获取的日志，显示所有内容都已完美加载！！

2013-01-08 11:30:19,759 INFO  BundleConfigurationLoader - Added 'PublishAction' for storage 'persistence' with 'com.tridion.storage.dao.JPAPublishActionDAO'.

现在，当我尝试将数据存储在我的表中时，我得到 “发生异常 com.tridion.broker.StorageException：无法持久保存数据实体，提交事务时出错，提交事务时出错”

这是我的实体类的任何问题还是我缺少的东西。

编辑：在 logback xml 中启用记录器级别“ON”之后。

我在核心文件中遇到以下异常：

2013-01-08 14:42:10,713 DEBUG SQL - insert into AUTN_ITEMS (ACTION, FLAG, ITEM_TYPE, LAST_PUBLISHED_DATE, PUBLICATION_ID, SCHEMA_ID, TCMURI, URL, ID) values (?, ?, ?, ?, ?, ?, ?, ?, ?)

com.microsoft.sqlserver.jdbc.SQLServerException: Cannot insert explicit value for identity column in table 'AUTN_ITEMS' when IDENTITY_INSERT is set to OFF.

谢谢

Answer 1

以上问题出在我的实体类中，我需要为我的身份列添加以下注释。

@Id
@Column(name = "ID", unique=true,updatable=false,insertable=false)
@GeneratedValue(strategy = GenerationType.AUTO)
private long id;

如果需要任何更改，请提出建议。

谢谢

Answer 2

ID 列应设置为在 db 级别自动递增。请查看我在 sdltridionworld 上的原始文章以获取示例 http://www.sdltridionworld.com/articles/sdltridion2011/tutorials/extending-content-delivery-storage-sdltridion-2011-1.aspx

"对于 SQL Server，列 ID 定义为 IDENTITY(1,1)，因此它会自动递增 1，而无需我们指定值。

对于 Oracle，需要使用序列（生成值）定义列 ID，如下所示： CREATE SEQUENCE SEQ_PUBLISH_ACTIONS MAXVALUE 999999999999999 CYCLE START WITH 1 / 创建或替换触发器 PUBLISH_ACTIONS_KEY 在 PUBLISH_ACTIONS 上插入之前 每一行 开始 IF :new.ID 为 NULL THEN SELECT SEQ_PUBLISH_ACTIONS.NEXTVAL INTO :new.ID FROM DUAL; 万一; 结尾; / "

Answer 3

您遇到的错误表明您的 ID 列未正确定义为身份，或者您正在尝试手动将值设置为此列中的自动生成值。 希望这会有所帮助。

问候， 丹尼尔。
