Marks a constructor,field,setter method or config method as to be autowired
by Spring’s dependency injection facilities. Only one constructor (at
max) of any given bean class may carry this annotation,indicating the
constructor to autowire when used as a Spring bean. Such a constructor
does not have to be public. Fields are injected right after
construction of a bean,before any config methods are invoked. Such a
config field does not have to be public. Config methods may have an
arbitrary name and any number of arguments; each of those arguments
will be autowired with a matching bean in the Spring container.@H_502_17@Bean property setter methods are effectively just a special case of such a
@H_502_17@general config method. Such config methods do not have to be public.
In the case of multiple argument methods,the ‘required’ parameter is
applicable for all arguments. In case of a Collection or Map
dependency type,the container will autowire all beans matching the
declared value type. In case of a Map,the keys must be declared as
type String and will be resolved to the corresponding bean names. Note
that actual injection is performed through a BeanPostProcessor which
in turn means that you cannot use @Autowired to inject references into
BeanPostProcessor or beanfactoryPostProcessor types. Please consult
the javadoc for the AutowiredAnnotationBeanPostProcessor class (which,
by default,checks for the presence of this annotation).
我的问题是：
>配置方法是什么意思？
>而且,假设我有@Autowired的setter方法和@Autowired的一些任意方法.我假设在bean实例化之后,spring会自动调用setter方法,而不会调用随机命名的@Autowired方法,对不对？
> Spring如何理解在实例化(setter)之后应该调用哪个@Autowired方法,而其他人不应该？这与javadoc的声明有何关联,并说：
Bean property setter methods are effectively just a special case of
such a general config method
最后一个问题：我可以在哪里阅读它？因为spring文档没有关于它的任何信息,我无法在其javadoc中找到spring使用的确切逻辑.
