UnsatisfiedDependencyException: There was no object available for injection at SystemInjecteeImpl
Please help
My Resource:
import javax.inject.Inject;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import com.walmart.services.helpers.IUserService;
import com.walmart.services.helpers.ServicesTest;
#Path("/sayHello")
public class ControllerTest {
#Inject
private IUserService service;
#Inject
private ServicesTest service2;
#GET
#Path("/{name}")
#Produces(MediaType.TEXT_PLAIN)
public String method(#PathParam("name") String msg) {
return service.method() + " msg";
}
#GET
#Path("/v2/{name}")
#Produces(MediaType.TEXT_PLAIN)
public String method2(#PathParam("name") String msg) {
return service2.method() + " msg";
}
}
My resource configuration file:
#ApplicationPath("/rest/*")
public class ResourceConfiguration extends ResourceConfig {
public ResourceConfiguration() {
//register(new MyBinder());
this.packages(true, "com.walmart.services.*");
}
}
My Binder [ if in place ]
public class MyBinder extends AbstractBinder
{
#Override
protected void configure() {
// TODO Auto-generated method stub
bind(new ServicesTest()).to(ServicesTest.class);
// bind(UserServiceImpl.class).to(IUserService.class).in(RequestScoped.class);
}
}
Services:
IUserService and its implementation
public interface IUserService {
public String method();
}
public class UserServiceImpl implements IUserService {
#Inject
public UserServiceImpl() {
System.out.println("test");
}
#Override
public String method() {
return "Welcome ";
}
}
Other
public class ServicesTest {
public ServicesTest() {
System.out.println("created ");
}
public String method() {
return "Welcome";
}
}

Now, i can access my resource using
http://localhost:8080/javaeeLearning/rest/sayHello/h
Which gives me below errors
SEVERE: Servlet.service() for servlet [com.walmart.configuration.ResourceConfiguration] in context with path [/javaeeLearning] threw exception [A MultiException has 4 exceptions. They are:
1. org.glassfish.hk2.api.UnsatisfiedDependencyException: There was no object available for injection at SystemInjecteeImpl(requiredType=IUserService,parent=ControllerTest,qualifiers={},position=-1,optional=false,self=false,unqualified=null,2007960340)

3. java.lang.IllegalArgumentException: While attempting to resolve the dependencies of com.walmart.services.rest.controller.ControllerTest errors were found
4. java.lang.IllegalStateException: Unable to perform operation: resolve on com.walmart.services.rest.controller.ControllerTest
] with root cause
And to resolve, i uncomment my Binder in Resource configuration
then i start having 404.

Answer 1

Make your JAX-RS resource a CDI bean like this:
#Path("/sayHello")
#RequestScoped
public class ControllerTest {
Then you don't need the Binder and injection should work.

Answer 2

You could set bean discovery mode to all in beans.xml:
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
bean-discovery-mode="all">
</beans>
or annatate UserServiceImpl with an scope annotation (like #Dependent)
