自动装配以休眠拦截器 [英] Autowired to hibernate Interceptor

问题描述

我正在扩展hibernate.EmptyInterceptor，并且在我的实现中，我想自动装入某些服务，但它们返回null。我在类上添加了@Component注释。我的代码：

I'm extending hibernate.EmptyInterceptor and in my implementation I would like to have autowired to some services but they return null. I added a @Component annotation over the class. My code:

<property name="jpaPropertyMap">
    <map>
        <entry key="javax.persistence.transactionType" value="JTA" />
        <entry key="hibernate.current_session_context_class" value="jta" />
        <entry key="hibernate.transaction.manager_lookup_class"
            value="com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup" />
        <entry key="hibernate.connection.autocommit" value="false" />
        <entry key="hibernate.ejb.interceptor" value="com.net.filter.AuditInterceptor"/>
    </map>
</property>

和课程：

and the class :

@SuppressWarnings("serial")
@Component
public class AuditInterceptor extends EmptyInterceptor {

    @Autowired
    private IUserSessionService userSessionService;

推荐答案

我知道这可能是两年来太晚了 - 但我正在寻找同样问题的答案，并认为这对未来某个人会有用。

I know this is probably coming two years too late - but I was searching for an answer for the same problem, and thought this would be useful to someone in the future.

查看Hibernate代码看起来像Hibernate会实例化一个新的拦截器的实例，如果你给类的名字，但如果你传入一个bean实例引用它将使用它。

Looking at Hibernate code looks like Hibernate would instantiate a new instance of the interceptor if you give the class name, but if you pass in a bean instance reference it will use that.

所以

<bean id="myInterceptor" class="com.net.filter.AuditInterceptor" />

...

<property name="jpaPropertyMap">
    <map>
        <entry key="javax.persistence.transactionType" value="JTA" />
        <entry key="hibernate.current_session_context_class" value="jta" />
        <entry key="hibernate.transaction.manager_lookup_class"
            value="com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup" />
        <entry key="hibernate.connection.autocommit" value="false" />
        <entry key="hibernate.ejb.interceptor" >
            <ref bean="myInterceptor" />
        </entry>
    </map>
</property>

现在，bean myInterceptor被Spring管理，自动装配将起作用！

Now the bean myInterceptor is Spring managed and autowiring will work!
