Thanks a lot jonK,it worked helped me.

here is the code.
public int getAttributes() {
        EmployeeDO employeeDo=new EmployeeDO();
        Class<?> e=employeeDo.getClass();
        return getAllAttributes(e);
    }

    private int getAllAttributes(Class<?> entityClass) {

        return entityClass.getDeclaredFields().length;
    }
