我有以下看似随机发生的异常：

    NHibernate.Exceptions.GenericADOException: could not execute query
    [ select businesspr0_.BusinessProcessID as col_0_0_, businesspr0_.ProcessNumber as col_1_0_, businesspr1_.Name as col_2_0_, businesspr0_.DateCreated as col_3_0_, actor2_.DisplayName as col_4_0_, usergroup3_.Name as col_5_0_, processele5_.Name as col_6_0_ from BusinessProcess businesspr0_ inner join BusinessProcess businesspr1_ on businesspr0_.DefinitionID=businesspr1_.BusinessProcessID inner join Actor actor2_ on businesspr0_.ActorCreatedID=actor2_.ActorID left outer join UserGroup usergroup3_ on businesspr0_.UserGroupCreatedID=usergroup3_.UserGroupID left outer join Actor usergroup3_1_ on usergroup3_.UserGroupID=usergroup3_1_.ActorID inner join ActiveElement activeelem4_ on businesspr0_.BusinessProcessID=activeelem4_.BusinessProcessID inner join ProcessElement processele5_ on activeelem4_.ProcessElementID=processele5_.ProcessElementID inner join ProcessEmployees processemp6_ on businesspr0_.BusinessProcessID=processemp6_.BusinessProcessID inner join Actor actor7_ …

我使用 spring 3.0.7、JUnit 4.11 和 DBUnit 2.4.9。我正在尝试在保存未指定多对一关系的实体（设置为空）时测试拖曳异常。这是实体：

<class name="DistributionPoint" table="distribution_point">
        <id name="id" unsaved-value="null" type="java.lang.Long">
            <column name="id"></column>
            <generator class="hilo"></generator>
        </id>

        <property name="name" type="java.lang.String">
            <column name="name" length="255"></column>
        </property>
        <property name="description" type="java.lang.String">
            <column name="description" length="1024"></column>
        </property>

        <property name="image" type="binary">
            <column name="image"></column>
        </property>

        <many-to-one name="site" class="Site">
            <column name="siteId" not-null="true"></column>
        </many-to-one>

    </class>

我创建了以下测试：

@TransactionConfiguration(defaultRollback=false, transactionManager="transactionManager")
//@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:/spring/mysql-test-context.xml" })
public class MysqlDistributionPointTest extends AbstractDatabaseTest {

AbstractDatabaseTest 扩展了 AbstractTransactionalJUnit4SpringContextTests。

测试方法为：

@Test(expected=org.hibernate.PropertyValueException.class)
    public void testSaveWithoutSite() {
        // set up DP
        DistributionPoint distributionPoint = new DistributionPoint(); …
