Define spring bean destroy method order

I have two beans BeanA and BeanB with destroy method defined by DisposableBean.

There is a requirement that the destroy method of BeanB must be invoked after the destroy method of BeanA.

How to implement that?

As you mentioned in comment beans are singletons, you can use depends_on. See Spring framework reference says as follows here

The depends-on attribute can specify both an initialization-time dependency and, in the case of singleton beans only, a corresponding destruction-time dependency. Dependent beans that define a depends-on relationship with a given bean are destroyed first, prior to the given bean itself being destroyed. Thus, depends-on can also control shutdown order.

If you prefer to use annotation based solution, you can use @DependsOn. Javadoc says as follows:

Dependent beans that define a depends-on relationship with a given bean are destroyed first, prior to the given bean itself being destroyed. Thus, a depends-on declaration can also control shutdown order.
