生命周期-InitializingBean和DisposableBean

通过实现InitializingBean和DisposableBean接口来定义初始化和销毁方法

public class Fish implements InitializingBean, DisposableBean {

    public void destroy() throws Exception {
        System.out.println("destroy method");
    }

    public void afterPropertiesSet() throws Exception {
        System.out.println("init method");
    }
}

init method
容器创建完成
