再次在任何 @PostConstruct 之前注入所有 @Resource
JSR-250 表示所有 @Resource 注释方法都将在 @PostConstruct 方法之前调用。
我的问题是：
这是否意味着上下文中所有 bean 上的所有 @Resource 注释方法都将在调用任何 @PostConstruct 注释方法之前调用？ 或者换句话说，一旦注入了依赖关系，即使上下文中的其他 bean 仍未注入依赖关系，是否可以调用 beans @PostConstruct 方法？
问候， 蒂姆.
JSR-250 says all @Resource annotated methods will be called before the @PostConstruct method..
My question is:
Does that mean that all @Resource annotated methods on all beans in a context will be called before any @PostConstruct annotated methods are called?
Or in other words can a beans @PostConstruct method be called once its dependencies have been injected even if other beans in the context still haven't had there dependences injected?
Regards,
Tim.

保证当给定 bean 的
@PostConstruct被调用时，它的所有@Resource字段都将被注入。如果这些注入中的任何一个本身都是具有自己的@Resource和@PostConstruct的 bean，那么它们将已经被调用。换句话说，在调用任何给定的 @PostConstruct 时，可以保证其所有依赖项都已完全初始化。事实上，在
BeanB实例化之前，BeanA可能会通过@PostConstruct被构造和初始化， ifBeanB对BeanA没有明确的依赖关系。It is guaranteed that when a given bean's
@PostConstructgets called, that all of its@Resourcefields will have been injected. If any of those injections are themselves beans with their own@Resourceand@PostConstruct, then those will have already been called. In other words, by the time any given@PostConstructis called, it is guaranteed that all of its dependencies have been fully initialized.It is possible, and in fact likely, that
BeanAwill be constructed and initialized via@PostConstructbeforeBeanBhas even been instantiated, ifBeanBhas no expressed dependency onBeanA.
