Hibernate 5转换插入问题

我正在开发一个从Hibernate3.4转换到5.4（以及从Spring3.4转换到5.4）的应用程序。它是一个WLS19.0.0.4服务器，Java8连接到DB2数据库。它在插入数据库时出现“HIBERNATE_序列是一个未定义的名称”错误（下面是堆栈跟踪）。它能够检索

在Hibernate 5中，是否有插入或生成序列值的语法更改或其他一些我没有考虑的更改

我研究并发现SQLCODE=-204，SQLSTATE=42704表示“对象不存在”，但我认为它与IBM无关，只是因为在Spring/Hibernate 3.4版本时我能够对它进行插入

Hibernate和persistence jars hibernate-core-5.4.2.Final.jar javax.persistence-api-2.2.jar（由于我看到的冲突，它取代了ejb3-persistence-1.0.2.GA.jar）

示例hbm.xml。这是我们方法的一个示例。它发生在所有的插页上

  <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>

我在下面的url找到了我的答案。我的设置是不同的，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_映射的默认值会导致相同的错误。（在Hib 3中为假，在Hib 5中为真）。因此，答案是将以下属性添加到hibernate.cfg.xml中。感谢@Eva Mariam的回答

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

false

我不知道您的问题的答案，但是

SQLCODE=-204，SQLSTATE=42704

源于Db2。我假设您运行的是同一个db，因此序列应该在那里。我最好的猜测是序列的模式在生成的查询中丢失了。据我所知，您没有提到Db2版本，但您可以尝试从syscat.sequences中选择seqschema，其中seqname='HIBERNATE_sequence'另一种可能性是序列名和/或seqschema在目录中引用，请尝试选择syscat.sequences中的seqschema和seqname，其中upper（seqname）=‘HIBERNATE_SEQUENCE’谢谢Lennart，我必须检查db2版本。我们使用WAS8.5.5运行这个应用程序，我使用WLS19.0.0.1和Spring/Hibernate3.6运行它。INSERT可用于这两种实现。这个问题从转换到Spring5.1.7/Hibernate5.4.2开始。感谢提醒您检查序列表。表日志的记录就在那里。我在这里找到了我的答案：我想你应该对此做一个简短的回答并接受它。你接受自己的答案不会得到任何分数，但我（可能还有其他人）会投赞成票，你会因此得到分数。
