java Hibernate JPA侦听器未收到调用

Question

设置我有一个老项目，它坚持JDK1.5，因此spring和hibernate版本也是支持这个java版本的最大可能版本。Hibernate是3.3.2。GA和spring为3.1.1。释放安装程序如下所示：

<persistence-unit name="myUnit" transaction-type="RESOURCE_LOCAL">
    <mapping-file>persistence-query.xml</mapping-file>
    ...
    <properties>
        <property name="hibernate.max_fetch_depth" value="3" />
        <property name="hibernate.show_sql" value="true" />
        <property name="hibernate.format_sql" value="true" />
        <property name="hibernate.hbm2ddl.auto" value="validate" />
        <property name="hibernate.ejb.interceptor" value="com.myproj.common.dao.AuditInterceptor"/>         
    </properties>
</persistence-unit>

</bean> 

还有我的拦截器：

@Component
public class AuditInterceptor extends EmptyInterceptor {

private static final long serialVersionUID = 98658932451L;

@Autowired
private JdbcTemplate jdbcTemplate;

public void afterTransactionBegin(Transaction tx) {
    if (user != null) {
        jdbcTemplate.execute("call ah_audit_pkg.SetAudit('test')");
        super.afterTransactionBegin(tx);
     }
 }  
}

我运行一个junit来测试拦截器是否被调用。在调试模式下，我可以看到：

感谢您的帮助！为什么我的intercetprot没有接到电话

编辑：

我还尝试了拦截器来覆盖后TransactionBegin，但没有帮助

我最终得到了以下解决方案： 我的entityt是从超类映射实体扩展而来的：

@Entity
@Table(name = "my_table")
public class MyTable extends AuditInfo

AuditInfo实体具有以下映射：

@MappedSuperclass
public abstract class AuditInfo implements Serializable {

...

    @PrePersist
    void onCreate() throws SQLException {
        //this empty method is needed for AOP to trigger the audit information insert before entity is stored
    }

    @PreUpdate
    void onPersist() throws SQLException {
        //this empty method is needed for AOP to trigger the audit information insert before entity is updated
    }

    @PreRemove
    void onRemove() throws SQLException {
        //this empty method is needed for AOP to trigger the audit information insert before entity is removed
    }
}

以及Aspect类：

@Aspect
@Component
public class MyAspect {

    @Before("execution(* com.mypackage.entities.AuditInfo.on*(..))")
    public void setAuditHistory(JoinPoint jp){      
        final AuditInfo info = ((AuditInfo)jp.getThis());
        JdbcTemplate jdbcTemplate = ApplicationContextProvider.getApplicationContext().getBean(JdbcTemplate.class);
        jdbcTemplate.execute(new CallableStatementCreator() {
            public CallableStatement createCallableStatement(Connection conn) throws SQLException {
                CallableStatement stmt = conn.prepareCall("begin ah_audit_pkg.SetAudit(?,?); end;");
                stmt.setString(1, info.getAuditUser());
                if(info.getAuditLocation() != null && info.getAuditLocation().trim().length() !=0) {
                    stmt.setString(2, info.getAuditLocation());
                } else {
                    stmt.setString(2, info.getAuditUser());
                }
                return stmt;
            }
        }, new CallableStatementCallback<Object>() {
            public Object doInCallableStatement(CallableStatement cs) throws SQLException, DataAccessException {
                return cs.executeUpdate();
            }
        });
    }  
}

需要注意的是，SpringBean是从上下文中提取的，而不是自动连接的——这是因为AOP在Spring实现中是一个单例类，并且即使在上下文中可用，也不会实例化任何自动连接的Bean。因此，我必须手动检索它们，以供以后使用
