[jboss-user] [JBoss/Spring Integration] - Is it SpringLifecycleInterceptor or just me?
The other day I decided to play a little with batch processing on JBoss + Spring EJB3 and
all.
Created this stateful session bean to force the Entity manager do a batch job for me on
remove
| @Stateful
| @Interceptors(SpringLifecycleInterceptor.class)
| @TransactionAttribute(NOT_SUPPORTED)
| public class StetefulBean implements Init {
| @PersistenceContext(unitName = "titan", type = EXTENDED)
| private EntityManager manager;
|
| @Spring(jndiName = "spring-pojo", bean = "statefulService")
| private TravelService service;
|
| @PostConstruct
| public void postConstruct() {
| service.setManager(manager);
| }
|
| public void initAirports(int index) {
| if (isInit(Airport.class)) {
| return;
| }
| List<Airport> lst = new ArrayList<Airport>();
|
| for (int i = 0; i < index; i++) {
| Airport port = new Airport();
| if (i % 2 == 0) {
| port.setName("Denver " + (i + 1));
| port.setAirportCode("dnvr_" + (i + 1));
| } else {
| port.setName("Hoover " + (i + 1));
| port.setAirportCode("hvr_" + (i + 1));
| }
| lst.add(port);
| }
| service.createAirports(lst);
| }
|
| @Remove
| @TransactionAttribute(REQUIRED)
| public void flush() {
| // syncrhonize with database;
| }
|
| private boolean isInit(Class clazz) {
| return service.getNumberOfObjects(clazz) == 0 ? false : true;
| }
| }
|
I am using this SpringLifecycleInterceptor.class from the JBoss+Spring distribution.
Unfortunately, that one is giving me kinda trouble throwing all kind of exceptions
OK. Made my own interceptor a la SpringLifecycleInterceptor
| public class StatefulBeanInterceptor extends SpringPassivationInterceptor {
| private static final long serialVersionUID = 1243234L;
| @PostConstruct
| public void postConstruct(InvocationContext ctx) throws Throwable {
| inject(ctx.getBean());
| ctx.proceed();
| }
| }
|
Wired it up. @Interceptors(StatefulBeanInterceptor.class)
Ran JBoss.
No problemo! Works like a charm. There might be something wrong with that
SpringLifecyleInterceptor thing from the distribution, or mine might be a bit obsolete
(I've downloaded sometime late June, I guess). No idea...
Another question - how to inject EntityManager from Spring configuration. Currently I am
using annotations and pushing manager to the service layer. Yet wiring it up from outside,
Spring, I mean, would be kinda kool to me.
Cheers,
Arno
