使用ajax传实体对象或实体对象集合

使用ajax传参有三种格式：字符串，xml，json

可以使用json来传递实体对象或传递实体对象的集合，方法如下：

传实体：

前台

var entity = {"id":selectedId,"meterCode":meterCode,"meterNumber":meterNumber,"employeeCode":employeeCode,"employeeName":employeeName,"operateResource":operateResource,"treatmentMeasures":treatmentMeasures};params: {               entityString: JSON.stringify(entity)            },        

后台接收

public ResponseResult closingWorkOder( @RequestParam String entityString) {SecurityEntity entity = JSONArray.toJavaObject((JSONObject) JSONArray.parse(entityString), SecurityEntity.class);            }        

传实体集合：

前台：

params: {                itemsEntities: JSON.stringify(downData)            },

这里的参数值类似于：

"[{"chargeName":"111","price":"11","count":"111","total":1221},{"chargeName":"111","price":"11","count":"111","total":1221}]"这种json串；

后台接收

public ResponseResult closingWorkOder(@RequestParam String itemsEntities) {List<SecurityTaskItemsEntity> itemsEntityList = JSONArray.parseArray(itemsEntities, SecurityTaskItemsEntity.class);            }
