Question

我们更新了以下罐子春天从3.1到4.0 Hibernate从4.1到4.3 JPA从1.0.1到2 JAVA从1.7到1.8 JBOSS 7.1.1最终到Wildfly 8服务器

我们的架构是这样的主表（有Id）父表（将主表的ID作为主键）子表（将主表作为主键的ID）

以上3个表有3个单独的pojo类，并通过继承加入父表和子表具有双向映射（一对多，多对一）

我的问题是为什么parent的findOne（Long Id）方法在升级到jar之前返回错误的子数据是正确的？

其次我们在映射中使用了DiscriminatorColumn和DiscriminatorValue但是在保存它时却无法插入异常，为什么这种行为是这样的呢？

第三个showSql = spring框架的true属性不能正常工作

我的主要表格

    @Entity
    @Audited
    @AuditTable(value="AUDIT_PRIMARY")
    @Table(name="PRIMARY")
    @Inheritance(strategy = JOINED)
    @DiscriminatorColumn(name = "TYPE", discriminatorType = INTEGER)
    public abstract class Primary implements Serializable {

    @Id
@Column(unique=true, nullable=false, precision=9)
@GeneratedValue(generator="PRIMARY_SEQ", strategy=GenerationType.SEQUENCE)
@SequenceGenerator(allocationSize=1,name="PRIMARY_SEQ", sequenceName="PRIMARY_SEQ")
private Long id;

我的父表和双向子映射

    @Entity
    @Audited
    @AuditTable(value="AUDIT_PARENT")
    @Table(name="PARENT")
    @PrimaryKeyJoinColumn(name = "PARENT_ID", referencedColumnName = "ID")
    @DiscriminatorValue("7")
    public class Parent extends Primary implements Serializable {

    @OneToMany(mappedBy="parent",cascade = CascadeType.ALL)
@AuditMappedBy(mappedBy="parent")
private List<Child> children;

我的Child表和父母的双向映射

    @Entity
    @Audited
    @AuditTable(value="AUDIT_CHILD")
    @Table(name="CHILD")
    @PrimaryKeyJoinColumn(name = "CHILD_ID", referencedColumnName = "ID")
    @DiscriminatorValue("6")
    public class Child extends Primary implements Serializable {

    @ManyToOne(cascade=CascadeType.ALL)
@JoinColumn(name="CHILD_PARENT_ID")
private Parent parent;

我的春季配置

    <tx:annotation-driven transaction-manager="transactionManager" />

<jpa:repositories base-package="com.proj.test.data.dao" entity-manager-factory-  ref="entityManagerFactory" transaction-manager-ref="transactionManager" />

<bean id="dbDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="java:jboss/datasources/db-ds" />
</bean>

<bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
    <property name="dataSource" ref="dbDataSource" />
    <property name="jpaDialect">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" />
    </property>
</bean>
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dbDataSource" />
    <property name="persistenceUnitName" value="persist" />
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
            <property name="generateDdl" value="false" />
            <property name="showSql" value="true" />
            <property name="database" value="ORACLE" />
        </bean>
    </property>
</bean>

加入继承无法正常工作
