页面传入json数组参数的处理代码
如：[{name:"张三"，value:"1"},{name:"李四"，value:"1"},{name:"王五"，value:"1"}]
思路：先在前段转化为string，然后把后台接收到的string转为list，这里要用到json的jar包
前段传送代码：
/**
* 添加标签
* @returns
*/
addLabels:function(){
var obj = {
labelsListAdd: JSON.stringify(tagManagerment.defaultOption.labelsListAdd)
};
commonAjax.ajaxSubmit("label/addLabels.do",obj,function(result){
if(result.resCode == 0){
layer.alert("添加成功！",function(){
location.reload();
});
}else{
layer.msg("未知错误，修复中")
}
});
},
后台接受代码
@Override
public ResultVO addLables(Map<String, String> map) throws Exception {
log.info(GlobalContract.LOG_BEGIN);
String list=map.get("labelsListAdd");
//把字符串转成list
List<LabelDto> labelsList=new ArrayList<LabelDto>();
JSONArray jsonList = JSONArray.fromObject(list);
LabelDto labelDto=null;
for(int i=0;i<jsonList.size();i++){
labelDto=new LabelDto();
LabelVO labelVO = (LabelVO)JSONObject.toBean(jsonList.getJSONObject(i),LabelVO.class);
labelDto.setCreatorId(Integer.parseInt(labelVO.getCreatorId()));
labelDto.setLabel_id(Integer.parseInt(labelVO.getValue()));
labelDto.setLabel_name(labelVO.getTypeDesc());
labelDto.setStore_id(Integer.parseInt(labelVO.getStore_id()));
labelDto.setSource_type(labelVO.getSource_type());
labelsList.add(labelDto);
}
labelDao.addLabels(labelsList);
ResultVO resultVO =new ResultVO();
log.info(GlobalContract.LOG_END);
return resultVO;
}
