我试过了。但是，由于我还很陌生，所以无法弄清问题。我已附上了几个屏幕截图，以查看我现在面临的问题。

@Path("/emp")
public class EmployeeService {

@GET
@Path("/emp/{empID}")
@Produces(MediaType.APPLICATION_XML)
public Employee getEmployee(@PathParam(value = "empID") String empID) {
    Employee employee = new Employee();
    employee.setEmailId(empID);
    employee.setName("Rony John");
    employee.setEmailId("rony.java@gmail.com");
    return employee;
}

@POST
@Path("/create")
@Consumes(MediaType.APPLICATION_XML)
@Produces(MediaType.APPLICATION_XML)
public Employee createEmployee(Employee employee) {
    // Create logic
    return employee;

}

@POST
@Path("/update")
@Consumes(MediaType.APPLICATION_XML)
@Produces(MediaType.APPLICATION_XML)
public Employee updateEmployee(Employee employee) {
    employee.setName(employee.getName() + " updated");
    return employee;
}

@DELETE
@Path("/delete/{empID}")
public Response deleteEmployee(@PathParam(value = "empID") String empID) {
    return Response.status(200)
            .entity("Employee with " + empID + " is deleted successfully.")
            .build();

}
}
