如题.
2.详情.
org.springframework.beans.factory包下有一个接口是InitializingBean 只有一个方法: /** * Invoked by a BeanFactory after it has set all bean properties supplied * (and satisfied BeanFactoryAware and ApplicationContextAware). * <p>This method allows the bean instance to perform initialization only * possible when all bean properties have been set and to throw an * exception in the event of misconfiguration. * @throws Exception in the event of misconfiguration (such * as failure to set an essential property) or if initialization fails. */ void afterPropertiesSet() throws Exception; 这个方法将在所有的属性被初始化后调用。 但是会在init前调用。 但是主要的是如果是延迟加载的话,则马上执行。 所以可以在类上加上注解: import org.springframework.context.annotation.Lazy; @Lazy(false) 这样spring容器初始化的时候afterPropertiesSet就会被调用。 只需要实现InitializingBean接口就行。 如果代码在这里初始化的话,半天都找不到。。
