Hibernate:在flush上“无法与会话同步数据库状态”

标签: hibernate exception

当我在下面的单元测试中尝试刷新时,我收到“无法将数据库状态与会话同步”。

任何人都可以告诉我问题是什么,因为我完全迷失了?我试过创建一个RuleDefinition,但没有任何属性设置,也不起作用。

由于

这是我的单元测试的片段,它扩展了AbstractTransactionalDataSourceSpringContextTests

@Test
public void testCreateRule() {
    RuleDefinition ruleReturned = (RuleDefinition) hibernateRuleDefinitionDao.findRule(1);
    RuleDefinition newRule = new RuleDefinition();
    newRule.setCurrentState("ACTIVE");
    newRule.setAttribute(ruleReturned.getSecondaryAttribute());
    newRule.setSecondaryAttribute(ruleReturned.getAttribute());
    newRule.setOperator(ruleReturned.getOperator());
    newRule.setPrecedence(4);
    hibernateRuleDefinitionDao.createRule(newRule);
    // Exception is thrown after the flush
    hibernateTemplate.flush();   
}

DAO方法只调用保存操作。这是我的映射文件

<class name="abc.def.rules.RuleDefinition" table="REFDATA.CONFIG_RULE_DEFINITION">
    <id name="ruleId" column="RULE_ID">
        <generator class="increment"/>
    </id>
    <many-to-one name="attribute" cascade="none" class="abc.def.rules.ConfigAttribute" lazy="false" column="CONFIG_ATTR_ID"/>
    <many-to-one name="operator" cascade="none" class="abc.def.rules.Operator" lazy="false">
        <column name="OPRTR_VAL"/>
        <column name="OPRTR_VAL_DATA_TYP"/>
    </many-to-one>
    <many-to-one name="secondaryAttribute" cascade="none" class="abc.def.rules.ConfigAttribute" lazy="false" column="CONFIG_ATTR_ID_2" not-null="false"/>
    <property name="operand" column="OPRND_VAL" type="string"/>
    <property name="trueAction" column="TRUE_ACTN" type="string"/>
    <property name="falseAction" column="FALSE_ACTN" type="string"/>
    <property name="precedence" column="RULE_ORD_SEQ" type="int" not-null="true"/>
    <property name="currentState" column="RULE_STAT" type="string"/>
</class>

这是我的Spring配置文件的片段

    <property name="driverClassName" value="org.hsqldb.jdbcDriver" />
    <property name="url" value="jdbc:hsqldb:mem:testdb" />

答案 0 :(得分:0)

我自己设法解决了这个问题。我的CONFIG_RULE_DEFINITION有一个约束,指定Timestamp列不应该为null,并且应该默认为SYSDATE。但是,SYSDATE在我假设的HSQLDB中不起作用。由于某种原因,没有这样的错误传播通知我这个。一旦我删除了这个约束,一切正常!
