hi,
yes, interceptor works fine with other component without @Startup
At first, i have two annotations
| @Target(TYPE)
| @Documented
| @Retention(RUNTIME)
| @Interceptors(KleberInterceptor.class)
| public @interface Kleber
| {
|
| }
|
interceptor is supposed to check filed with @Jndi annotation and take the
string from @jndi for jndi lookup
| public class KleberInterceptor {
|
| @PostConstruct
| public Object jndiLookup(InvocationContext invocation )throws Exception{
| Object target = invocation.getTarget();
| Field[] fields = target.getClass().getDeclaredFields();
|
| try{
| InitialContext ctx = new InitialContext();
| for(Field field: fields){
| Jndi jndi = field.getAnnotation(Jndi.class);
| if(jndi!=null){
| Object obj = ctx.lookup(jndi.value());
| field.setAccessible(true);
| field.set(target, obj);
| }
| }
|
| }catch(Exception ex){
| ex.printStackTrace();
| }
|
| return invocation.proceed();
| }
|
| @AroundInvoke
| otherMethods............
|
|
| }
|
I can not use @Kleber on a component which already has a @Startup, what i can
do now ,is to write jndi lookup codes directly in @Startup component, and it
works.....
is there any better way to inject jndi resouce in @Startup Seam component?
