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