struts1通过修改父Dispatchaction 达到权限控制

1,通过修改父Dispatchaction 达到控制权限，重写DispatchAction的execute方法，加入权限控制，后再调用父类方法

public abstract class BaseDispatchAction extends DispatchAction {
	// 初始化ActionMessages，以方便其继承的类使用
	protected ActionMessages messages = null;
	
	@Override
	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response)
			throws Exception {
		// TODO Auto-generated method stub
		String method= request.getParameter("method");
		Permission ps = this.getPermission(mapping, request);
		ps = new Permission(true,true,true,true,true);
		
		if ("list".equals(method)) {
			if(ps.canAccessOrRead()) {

				return super.execute(mapping, form, request, response);
			}else {
				throw new ErrorCodeException(MessageConst.EXCEPTION_10002,"can not read or access...");
			}
		}
		return super.execute(mapping, form, request, response);
		
		
	}

 

 2 ，得到变量本身的变量名

	public static void main(String[] args) throws Exception {
		// 测试代码用来获取一个JLabel中声名的所有的属性名和其属性变量
		Const cons = new Const();
		Field[] fields = cons.getClass().getDeclaredFields();
		s.getClass().getDeclaredFields();
		for (int i = 0, len = fields.length; i < len; i++) {
			String varName = fields[i].getName();
			Object o = fields[i].get(cons);
			System.out.println("传入的对象中包含一个如下的变量：" + varName+"="+o );
		}
		
	}
