本文介绍了一种前端使用jQuery进行数据封装并发送AJAX请求的方法,同时展示了后端SpringMVC如何接收并处理这些JSON数据,完成数据的持久化。

1.jsp封装数据，示例中是list数组

var saveList = new Array();
$.each($("#hasList tr"), function(i, n){
	var a = $(n).find("td:first a"),
		id = $(a).attr("data-id"),
		name = $(a).text();
	saveList.push({id:id,name:name});
});

2.ajax提交请求

$.ajax({
	type: "POST",
	url: "<%=basePath %>manage/setSchoolList",
	contentType: 'application/json;charset=utf-8', //设置请求头信息
	data: $.toJSON(saveList),
	async: false,
	success: function(data){
		alert("设置成功");
	}
});

3.springmvc接收数据

@ResponseBody
@RequestMapping(value = "/setSchoolList", method = {RequestMethod.POST})
public String setSchoolList(@RequestBody List<Map<String, Object>> list) {
	String date = DateTool.getCurrenttime();
	List<School> schoolList = new ArrayList<School>();
	int count = 1;
	for (Map<String, Object> map : list) {
		School school = new School();
		for (String key : map.keySet()) {
			String value = (String) map.get(key);
			if ("id".equals(key)) {
				school = JsonpUtil.getSchoolBySchoolId(value);
			}
		}
		school.setCreateTime(date);
		school.setOrderNum(count++);
		schoolList.add(school);
	}
	schoolService.insert(schoolList);
	
	return "success";
}
