Я пытаюсь протестировать минимальный механизм внедрения JAX-RS + EJB/CDI и в настоящее время сталкиваюсь с препятствием из-за того, что GlassFish не может внедрить по какой-либо причине.
(Использование @Inject вызовет NPE, потому что GlassFish не может внедрить POJO).
Мой beans.xml содержит только
<beans />
Вот мой web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

@Path("/employee")
public class EmployeeResource {
@EJB
ApplicationScopedEmployeeServiceImpl employeeService;
@Path("/all")
@GET

public List<Employee> index() {
return this.employeeService.getAllEmployees();
}
}

Вот класс ресурсов JAX-RS:
import java.util.List;
import javax.ejb.EJB;
import javax.ejb.Stateless;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
@Stateless
@Path("/employee")
public class EmployeeResource {
@EJB
ApplicationScopedEmployeeServiceImpl employeeService;
@Path("/all")
@GET
@Produces({ MediaType.APPLICATION_XML })
public List<Employee> index() {
return this.employeeService.getAllEmployees();
}
}
И последнее, но не менее важное: фактический EJB:
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import javax.ejb.Stateless;
@Stateless
public class ApplicationScopedEmployeeServiceImpl implements EmployeeService {
final List<Employee> employees = new ArrayList<Employee>();
public ApplicationScopedEmployeeServiceImpl() {
final Employee employee = new Employee();
employee.setEmployeeId(new Date().getTime());
employee.setFirstName("FirstName-" + employee.getEmployeeId());
employee.setMiddleName("MiddleName-" + employee.getEmployeeId());
employee.setLastName("LastName-" + employee.getEmployeeId());
employee.setScoped("ApplicationScoped");
this.employees.add(employee);
}
/**
* {@inheritDoc}
*/
public List<Employee> getAllEmployees() {
return this.employees;
}
}
И это исключение из GlassFish

Кто-нибудь знает, есть ли проблема с JAX-RS и GF 3.1?
Код работает, если это сервлет :)
