Javascript：
data:{"updValRecords":'[{"taskId":100, "coutp":980},{"taskId":101, "coutp":981}]'},
注意：已字符串形式传递List内容
Action中该List的定义
private List<ValRecordModel> updValRecords;
public void setUpdValRecords(String updValRecordsStr) {
JSONArray jsonArray = JSONArray.fromObject(updValRecordsStr);
this.updValRecords = (List<ValRecordModel>)JSONArray.toList(jsonArray, ValRecordModel.class);
}
