/**
|
|
* The <code>PostConstruct</code> annotation is used on a method that needs to
|
|
* be executed after dependency injection is done to perform any initialization.
|
|
* This method must be invoked before the class is put into service. This
|
|
* annotation must be supported on all classes that support dependency
|
|
* injection. The method annotated with <code>PostConstruct</code> must be
|
|
* invoked even if the class does not request any resources to be injected. Only
|
|
* one method in a given class can be annotated with this annotation. The method
|
|
* on which the <code>PostConstruct</code> annotation is applied must fulfill
|
|
* all of the following criteria:
|
|
* <ul>
|
|
* <li>The method must not have any parameters except in the case of
|
|
* interceptors in which case it takes an <code>InvocationContext</code> object
|
|
* as defined by the Interceptors specification.</li>
|
|
* <li>The method defined on an interceptor class or superclass of an
|
|
* interceptor class must have one of the following signatures:
|
|
* <p>
|
|
* void <METHOD>(InvocationContext)
|
|
* <p>
|
|
* Object <METHOD>(InvocationContext) throws Exception
|
|
* <p>
|
|
* <i>Note: A PostConstruct interceptor method must not throw application
|
|
* exceptions, but it may be declared to throw checked exceptions including the
|
|
* java.lang.Exception if the same interceptor method interposes on business or
|
|
* timeout methods in addition to lifecycle events. If a PostConstruct
|
|
* interceptor method returns a value, it is ignored by the container.</i></li>
|
|
* <li>The method defined on a non-interceptor class must have the following
|
|
* signature:
|
|
* <p>
|
|
* void <METHOD>()</li>
|
|
* <li>The method on which the <code>PostConstruct</code> annotation is applied
|
|
* may be public, protected, package private or private.</li>
|
|
* <li>The method must not be static except for the application client.</li>
|
|
* <li>The method should not be final.</li>
|
|
* <li>If the method throws an unchecked exception the class must not be put
|
|
* into service except in the case where the exception is handled by an
|
|
* interceptor.</li>
|
|
* </ul>
