Msg类

public class Msg {

		private int code;//状态码：100表示成功，200表示失败
		private String result;//操作成功、操作失败
		private Map<String, Object> data = new HashMap<String, Object>();
		
		
		//返回成功结果的方法
		public static Msg success(){
			Msg msg = new Msg();
			msg.setCode(100);
			msg.setResult("操作成功");
			return msg;
		}
		//返回失败结果的方法
		public static Msg fail(){
			Msg msg = new Msg();
			msg.setCode(200);
			msg.setResult("操作失败");
			return msg;
		}
		
		//存放数据，支持链式操作
		public Msg add(String key,Object value){
			this.getData().put(key, value);
			return this;		
		}
