Is there any init method given for struts2 action class?

Question

Is there any init method provided for struts 2 action class that can be called before every method of that action class?

For example, I have an action class for struts 2 as given below

import com.opensymphony.xwork2.ActionSupport;

public class EmployeeAction extends ActionSupport{

    private  DepartmentDaoService deptService = new DepartmentDaoService() ;
    private  EmployeeDaoService empService = new EmployeeDaoService();
    private Employee employee;
    private List<Employee> employees;
    private List<Department> departments;

       public void init()
       {
          //Do initialization stuff here
       }

       public String getAllEmployees(){
          employees = empService.getAllEmployees();
          return "success";
       }

       public String deleteEmployee(){
        empService.deleteEmployee(employee.getEmployeeId());
        return "success";
       }
}

Now in above code when struts action for getAllEmployees() and deleteEmplyee() is called I want init() method to execute first. We can run it by calling it from both functions.

But is there any provision given in struts 2 that will run init method automatically on each call or struts 2 provides any such method for action clases?

Please tell me if anyone knows.

Thanks.
