【问题描述】：

我正在开发一个应用程序，我们正在从 Hibernate 3.4 转换到 5.4（以及 Spring 3.4 到 5.4）。它是一个 WLS 19.0.0.4 服务器，java 8 连接到 DB2 数据库。插入数据库时​​出现“HIBERNATE_SEQUENCE IS AN UNDEFINED NAME”错误（下面的堆栈跟踪）。它能够检索。

在 Hibernate 5 中是否存在插入或生成序列值的语法更改或我未考虑的其他更改？

我研究发现 SQLCODE=-204, SQLSTATE=42704 表示“对象不存在”，但我认为它与 IBM 无关，只是因为我能够在它是 Spring/Hibernate 时对其进行插入3.4

休眠和持久化 jar hibernate-core-5.4.2.Final.jar javax.persistence-api-2.2.jar（由于我看到的冲突，它替换了 ejb3-persistence-1.0.2.GA.jar）

示例 hbm.xml。这是我们方法的一个示例。它发生在所有插入中

  <class name="somepath.TableLog" table="TABLE_NAME">

    <id name="id" type="java.lang.Long" access="field">
        <column name="SYS_ID" />
        <generator class="sequence">
            <param name="sequence">TABLE_LOG_SEQ</param>
        </generator>
    </id>
    <property name="logEntry" type="java.lang.String" access="field">
        <column name="LOG_ENTRY" length="32000" />
    </property>
    <property name="userId" type="java.lang.String" access="field">
        <column name="USER_ID" length="2" />
    </property>

</class>

对应类 - logEntry 的 getter 和 setter 在父类中。

public class TableLog extends AbstractLog 

    private String userId = "";
    public TableLog (String logEntry,  String userId) 
        super(logEntry, userId);
    
    /**
     * Instantiates a new sys mgmt log.
     */
    public TableLog() 
        super();                
    

    public String getUserId() 
        return userId;
    

    public void setUserId(String userId) 
        this.userId = userId;
    

hibernate-hsqldb.cfg.xml

【问题讨论】：

我不知道您的问题的答案，但 SQLCODE=-204, SQLSTATE=42704 来自 Db2。我假设你运行的是同一个数据库，所以序列应该在那里。我最好的猜测是序列的模式在生成的查询中丢失了。

据我所见，您没有提及Db2版本，但是您可以尝试select seqschema from syscat.sequences where seqname = 'HIBERNATE_SEQUENCE'另一种可能性是在目录中引用了序列名称和/或seqschema，请尝试@987654328 @

谢谢Lennart，我得检查一下db2 版本。我们使用 WAS 8.5.5 运行相同的应用程序，而我使用带有 Spring/Hibernate 3.6 的 WLS 19.0.0.1 运行它。插入适用于这两种实现。这个问题从转换到 Spring 5.1.7 /Hibernate 5.4.2 开始。感谢您提醒检查序列表。 TABLE_LOG_SEQ 的记录在那里。

我在这里找到了答案：***.com/questions/32968527/…

我认为你应该对此做一个简短的回答并接受它。接受自己的答案不会获得任何分数，但我（可能还有其他人）会投票给它，你会因此获得分数。

【参考方案1】：

我在下面的网址找到了答案。我的设置不同，因为我们使用的是序列表中的序列名称，但是更改为 hibernate.id.new_generator_mappings 的默认值的效果导致了相同的错误。 （在 Hib 3 中它是假的，在 hib 5 中它是真的）。所以答案是在hibernate.cfg.xml中加入如下属性。感谢@Eva Mariam 的回答。

<property name="hibernate.id.new_generator_mappings">false</property>
