Package org.springframework.orm.hibernate.support

Class DependencyInjectionInterceptorFactoryBean

  • All Implemented Interfaces:
    org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.FactoryBean, org.springframework.beans.factory.InitializingBean
    public class DependencyInjectionInterceptorFactoryBean
extends DependencyInjectionAspectSupport
implements org.springframework.beans.factory.FactoryBean
    Allows Spring to create and wire up objects that come from Hibernate. This enables richer domain models, with domain objects able to access business objects.

    When creating such objects in application code, before persisting them, you can apply configuration manually via Setters, use factory autowiring, or obtain a prototype from the factory. A dependency on Spring IoC can be avoided by using a lookup-method to obtain the prototype instance.

    This is a factory bean, as we want to extend DependencyInjectionAspectSupport yet be usable as a Hibernate Interceptor.

    Typically, the Hibernate SessionFactory will be set via the "sessionFactoryName" property: this avoids a circular dependency between SessionFactory (requiring an Interceptor) and this Interceptor (requiring a SessionFactory).

    Based on a constribution by Oliver Hutchison. Thanks also to Seth Ladd.

    • Method Detail

      • setNextInterceptor

        public void setNextInterceptor​(org.hibernate.Interceptor nextInterceptor)
        As Hibernate doesn't support chaining of interceptors natively, we add the ability for chaining via a delegate.

      • getNextInterceptor

        public org.hibernate.Interceptor getNextInterceptor()
        Reutn the next Interceptor in the chain, or null if this is the only interceptor.

      • setSessionFactory

        public void setSessionFactory​(org.hibernate.SessionFactory sessionFactory)
        We need the Hibernate SessionFactory to work out identifier property name to set PK on object.
        Parameters:
        sessionFactory - bean name of the Hibernate SessionFactory this interceptor should configure persistent object instances for

      • setSessionFactoryName

        public void setSessionFactoryName​(String sessionFactoryName)
        Alternative to the sessionFactory property. Use this property to avoid circular dependencies between interceptor and SessionFactory. The session factory will be looked up on validation.
        Parameters:
        sessionFactoryName - bean name of the Hibernate SessionFactory this interceptor should configure persistent object instances for

      • getObjectType

        Specified by:
        getObjectType in interface org.springframework.beans.factory.FactoryBean

      • isSingleton
