시작 J2EE 7 - Antonio Gonclaves에서 소스 코드를 읽는 중 "org.glassfish.hk2.api.UnsatisfiedDependencyException"예외가 발생했습니다. 풀다. 한정자가 없으면 응용 프로그램이 올바르게 작동합니다. Netbeans 7.3.1과 Glassfish 4.0을 사용하고 있습니다. 다음은 내 소스 코드와 예외 로그입니다Jersey 2.0 및 CDI에서 한정자 사용
이 나는
@Stateless
@ISBNAlt
public class ISBNGenerator implements INumberGenerator{
@Override
public String generateNumberr() {
return "ISBN generated";
}
}
두 번째 서비스 클래스
@Stateless
@ISBNDef
public class ISSNGenerator implements INumberGenerator{
@Override
public String generateNumberr() {
return "Working version 2";
}
}
자원을 차별화하는 @Qualifiers을 사용하고 내 서비스 클래스는 등급
@ManagedBean
@RequestScoped
@Path("/test")
public class TestClass {
@Inject @ISBNAlt
private INumberGenerator ng;
@Produces(MediaType.TEXT_PLAIN)
@GET
public String getValue()
{
return ng.generateNumberr();
}
}
그리고 난 내 응용 프로그램을 배포하고 REST 엔드 포인트를 호출 한 후 자원 클래스
import java.util.Set;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
/**
*
* @author naphlin
*/
@ApplicationPath("webresource")
public class ApplicationConfig extends Application{
@Override
public Set<Class<?>> getClasses() {
Set<Class<?>> resources = new java.util.HashSet<Class<?>>();
// following code can be used to customize Jersey 2.0 JSON provider:
try {
Class jsonProvider = Class.forName("org.glassfish.jersey.jackson.JacksonFeature");
// Class jsonProvider = Class.forName("org.glassfish.jersey.moxy.json.MoxyJsonFeature");
// Class jsonProvider = Class.forName("org.glassfish.jersey.jettison.JettisonFeature");
resources.add(jsonProvider);
} catch (ClassNotFoundException ex) {
java.util.logging.Logger.getLogger(getClass().getName()).log(java.util.logging.Level.SEVERE, null, ex);
}
addRestResourceClasses(resources);
return resources;
}
/**
* Do not modify addRestResourceClasses() method.
* It is automatically re-generated by NetBeans REST support to populate
* given list with all resources defined in the project.
*/
private void addRestResourceClasses(Set<Class<?>> resources) {
resources.add(helpers.TestClass.class);
}
}
을 추가하기위한이 클래스를 사용, 난이 예외
