| aoqi@0 | 32 | /** |
| aoqi@0 | 33 | * The PostConstruct annotation is used on a method that needs to be executed |
| aoqi@0 | 34 | * after dependency injection is done to perform any initialization. This |
| aoqi@0 | 35 | * method MUST be invoked before the class is put into service. This |
| aoqi@0 | 36 | * annotation MUST be supported on all classes that support dependency |
| aoqi@0 | 37 | * injection. The method annotated with PostConstruct MUST be invoked even |
| aoqi@0 | 38 | * if the class does not request any resources to be injected. Only one |
| aoqi@0 | 39 | * method can be annotated with this annotation. The method on which the |
| aoqi@0 | 40 | * PostConstruct annotation is applied MUST fulfill all of the following |
| aoqi@0 | 41 | * criteria: |
| aoqi@0 | 42 | * <p> |
| aoqi@0 | 43 | * <ul> |
| aoqi@0 | 44 | * <li>The method MUST NOT have any parameters except in the case of |
| aoqi@0 | 45 | * interceptors in which case it takes an InvocationContext object as |
| aoqi@0 | 46 | * defined by the Interceptors specification.</li> |
| aoqi@0 | 47 | * <li>The method defined on an interceptor class MUST HAVE one of the |
| aoqi@0 | 48 | * following signatures: |
| aoqi@0 | 49 | * <p> |
| aoqi@0 | 50 | * void <METHOD>(InvocationContext) |
| aoqi@0 | 51 | * <p> |
| aoqi@0 | 52 | * Object <METHOD>(InvocationContext) throws Exception |
| aoqi@0 | 53 | * <p> |
| aoqi@0 | 54 | * <i>Note: A PostConstruct interceptor method must not throw application |
| aoqi@0 | 55 | * exceptions, but it may be declared to throw checked exceptions including |
| aoqi@0 | 56 | * the java.lang.Exception if the same interceptor method interposes on |
| aoqi@0 | 57 | * business or timeout methods in addition to lifecycle events. If a |
| aoqi@0 | 58 | * PostConstruct interceptor method returns a value, it is ignored by |
| aoqi@0 | 59 | * the container.</i> |
| aoqi@0 | 60 | * </li> |
| aoqi@0 | 61 | * <li>The method defined on a non-interceptor class MUST HAVE the |
| aoqi@0 | 62 | * following signature: |
| aoqi@0 | 63 | * <p> |
| aoqi@0 | 64 | * void <METHOD>() |
| aoqi@0 | 65 | * </li> |
| aoqi@0 | 66 | * <li>The method on which PostConstruct is applied MAY be public, protected, |
| aoqi@0 | 67 | * package private or private.</li> |
| aoqi@0 | 68 | * <li>The method MUST NOT be static except for the application client.</li> |
| aoqi@0 | 69 | * <li>The method MAY be final.</li> |
| aoqi@0 | 70 | * <li>If the method throws an unchecked exception the class MUST NOT be put into |
| aoqi@0 | 71 | * service except in the case of EJBs where the EJB can handle exceptions and |
| aoqi@0 | 72 | * even recover from them.</li></ul> |
