Annotation Interface DependsOn
Beans on which the current bean depends. Any beans specified are guaranteed to be
created by the container before this bean. Used infrequently in cases where a bean
does not explicitly depend on another through properties or constructor arguments,
but rather depends on the side effects of another bean's initialization.
A depends-on declaration 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, a depends-on declaration can also control shutdown order.
May be used on any class directly or indirectly annotated with
Component
or on methods annotated
with Bean
.
Using DependsOn
at the class level has no effect unless component-scanning
is being used. If a DependsOn
-annotated class is declared via XML,
DependsOn
annotation metadata is ignored, and
<bean depends-on="..."/>
is respected instead.
