Jersey & Spring spravovali poskytovateľov - java, spring, jersey, jersey-2.0

Používam Jersey 2.4.1, Jar 3.2.4 a Mólo 7.

Nerozumiem tomu, ako Jersey registruje poskytovateľov spravovaných na jar. Moje triedy boli komentované @Provider sú tiež anotované @Component pretože potrebujem injekciu. Nakonfiguroval som Jersey, aby prehľadával moje balíčky u týchto poskytovateľov.

Takto nakonfigurujem Jersey servlet:

public void createJerseyServlet() {
ResourceConfig resourceConfig = new ResourceConfig();
resourceConfig.packages("test.web", "org.glassfish.jersey.server.spring");
resourceConfig.register(LoggingFilter.class);
ServletHolder servletHolder = new ServletHolder(new ServletContainer(resourceConfig));
servletContextHandler.addServlet(servletHolder, "/*");
}

Denníky pri spustení:

INFO - org.glassfish.jersey.server.spring.SpringComponentProvider - Spring context lookup done.
INFO - org.glassfish.jersey.server.spring.SpringComponentProvider - Spring component provider initialized.
INFO - org.glassfish.jersey.server.spring.SpringComponentProvider - Spring managed bean, testResource, registered with HK2.
INFO - org.glassfish.jersey.server.spring.SpringComponentProvider - Spring managed bean, nullPointerExceptionMapper, registered with HK2.
INFO - org.glassfish.jersey.server.spring.SpringComponentProvider - Spring managed bean, filterTest, registered with HK2.
[...]
INFO - org.glassfish.jersey.server.ApplicationHandler - Jersey application initialized.
Root Resource Classes:
org.obiba.jta.web.TestResource
Pre-match Filters:
org.glassfish.jersey.filter.LoggingFilter
Global Response Filters:
org.glassfish.jersey.filter.LoggingFilter
Global Reader Interceptors:
org.glassfish.jersey.server.internal.MappableExceptionWrapperInterceptor
Global Writer Interceptors:
org.glassfish.jersey.filter.LoggingFilter
[...]

Moji poskytovatelia sa zisťujú prostredníctvom jari: Spring managed bean, filterTest, registered with HK2 ale neobjavujú sa v ApplicationHandler protokoly ... Pri spustení aplikácie sa nepoužívajú.

Musím ich zaregistrovať manuálne:

@Resource
private FilterTest filterTest;

@Resource
private MyExceptionMapper myExceptionMapper;

[...]

resourceConfig.register(filterTest);
resourceConfig.register(myExceptionMapper);

Alebo ešte lepšie ... pre riešenie :(

Map<String, Object> providers = applicationContext.getBeansWithAnnotation(Provider.class);
for(Object provider : providers.values()) {
resourceConfig.register(provider);
}

Teraz to funguje (aj keď sa ešte stále neobjavujú) ApplicationHandler denníky), ale nechápem, prečo ich Jersey nezaregistruje automaticky, keď prehľadá balík a zistí, že tieto fazule sú spravované na jar ...

Tu sú moje komponenty ...

prostriedky

package test.web;

@Transactional
@Component
@Path("/test")
public class TestResource {
@Resource
private MyService myService;

@GET
@Path("/inject")
@Produces(MediaType.TEXT_PLAIN)
public String testInjection() {
return "integrationService: " + integrationService;
}

@GET
@Path("/active")
@Produces(MediaType.TEXT_PLAIN)
public String testActiveTransaction() {
return "isActualTransactionActive: " + TransactionSynchronizationManager.isActualTransactionActive();
}

@GET
@Path("/exception")
@Produces(MediaType.TEXT_PLAIN)
public String testException() {
throw new MyException();
}
}

filter

package test.web.cfg;

@Provider
@Component
public class FilterTest implements ContainerRequestFilter {
@Resource
private MyService myService;
[...]
}

ExceptionMapper

package test.web.cfg;

@Provider
@Component
public class MyExceptionMapper implements ExceptionMapper<MyException> {
@Override
public Response toResponse(MyException exception) {
return Response.status(Response.Status.INTERNAL_SERVER_ERROR).entity("MyException was thrown!").build();
}
}

A nakoniec moje závislosti

compile("org.glassfish.jersey.core:jersey-common:2.4.1")
compile("org.glassfish.jersey.core:jersey-server:2.4.1")
compile("org.glassfish.jersey.containers:jersey-container-servlet-core:2.4.1")
compile("org.glassfish.jersey.media:jersey-media-multipart:2.4.1")
compile("org.glassfish.jersey.connectors:jersey-apache-connector:2.4.1")
compile("org.glassfish.jersey.ext:jersey-spring3:2.4.1")

Je to chyba ...
