json格式的读写,struts标签的使用

java

 

package com.appbox.util.validate;
//检查字段非空
public class TextUtils {
	
	public static boolean isEmpty(String str) {
		if (str == null) {
			return true;
		}
		if ("".equalsIgnoreCase(str)) {
			return true;
		}
		return false;
	}

}

         
      private List
  
    getMediaFilter(MediaAd mediaAd) {
		List
   
     filters; String jsonStr = mediaAd.getMediafilterAd(); if (! TextUtils.isEmpty(jsonStr)) { System.out.println("filter json : " + jsonStr); filters = JSON.parseArray(jsonStr, String.class); } else { System.out.println("filter json default: " + jsonStr); filters = new ArrayList
    
     (); } return filters; } /** * 添加过滤 * @return */ public String addmediafilter(){ System.out.println("json 是个啥："+JSON.toJSONString(this.textFilter)); mediafilter();//获得media id JSONObject jo = new JSONObject(); if(textFilter == null || "".equals(textFilter)){ jo.put("message", "请填写要过滤的广告名"); return ajaxJson(jo.toJSONString()); } filters = getMediaFilter(mediaAd); if(filters.contains(textFilter)){ System.out.println("已有此文本"); jo.put("message", "已有此文本"); return ajaxJson(jo.toJSONString()); } filters.add(this.textFilter); mediaAd.setMediafilterAd(JSON.toJSONString(filters)); boolean flag = mediaAdService.upd(mediaAd); if (flag) { jo.put("success", true); } else { jo.put("success", false); jo.put("message", "添加失败"); } return ajaxJson(jo.toJSONString()); } /** * 删除过滤文本 * @return */ public String delmediafilter(){ mediafilter(); System.out.println("del 文本["+textFilter+"]"); if(textFilter== null || "".equals(textFilter)){ System.out.println("id 为空"); errormessage = "文字为空"; return mediafilter(); } JSONObject jo = new JSONObject(); filters = getMediaFilter(mediaAd); boolean flag = filters.remove(textFilter); mediaAd.setMediafilterAd(JSON.toJSONString(filters)); mediaAdService.upd(mediaAd); flag = mediaAdService.upd(mediaAd); if (flag) { jo.put("success", true); } else { jo.put("success", false); jo.put("message", "删除失败"); } return ajaxJson(jo.toJSONString()); }
