在grails中配置LocalSessionFactoryBean的属性

LocalSessionFactoryBean的Grails版本是一个子类,org.codehaus.groovy.Grails.orm.hibernate.ConfigurableLocalSessionFactoryBean。它在org.codehaus.groovy.grails.plugins.orm.hibernate.HibernatePluginSupport中注册为SpringBean

sessionFactory(ConfigurableLocalSessionFactoryBean) {
   ...
}

所以你有几个选择。一个是在resources.groovy中重新定义bean,维护Grails配置的内容和您的更改,即。

sessionFactory(MyCustomConfigurableLocalSessionFactoryBean) {
   ...
   typeDefinitions = ...
}

或者,如果可能,可以引用bean并在引导中修改它:

class BootStrap {

   def sessionFactory

   def init = { servletContext ->
      sessionFactory.foo = bar
   }

   def destroy = {}
}

在factory bean构建SessionFactory时,typeDefinitions似乎需要提前配置,因此选项1可能是您的最佳选择。

另一种选择是使用spring的生命周期回调,例如实现beanpstprocessor

public class CustomBeanPostProcessor implements BeanPostProcessor {

// simply return the instantiated bean as-is
public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {
    return bean; // we could potentially return any object reference here...
}

public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
    if ("sessionFactory".equals(beanName) && bean instanceof ConfigurableLocalSessionFactoryBean)  {
        ConfigurableLocalSessionFactoryBean sessionFactory = (ConfigurableLocalSessionFactoryBean) bean;
        sessionFactory.setTypeDefinitions(...);
    }
    return bean;
}

}

把它扔给你的资源
