Annotation Type PostConstruct

@Retention(value=RUNTIME)
@Target(value=METHOD)
public @interface PostConstruct

The PostConstruct annotation is used on a method that needs to be executed after dependency injection is done to perform any initialization. Such methods are so-called post construct methods. This annotation is also supported for interceptor methods, further referred to as post-construct lifecycle methods.

PostConstruct methods are invoked by the container before beanlet instances are put into service. The post-construct method is called even if the class does not request any resources to be injected. The beanlet instance is not put into service if an exception is thrown by this method.

Method Constraints

Only one method can be marked with this annotation. The method on which the PostConstruct annotation is applied MUST fulfill all of the following criteria:

• The method MUST NOT have any parameters except in the case of interceptors in which case it MUST take an InterceptorContext object.
• The method MAY return any type.
• The method MAY throw a checked exception.
• The method on which PostConstruct is applied MAY be public, protected, package private or private.
• The method MUST NOT be static.
• The method MAY be final.
