springmvc接受form表单提交多个name相同的字段参数 - 好文

本人菜鸟一枚，写博客是为了记录自己在开发过程中遇到的问题，欢迎大家交流留言，勿喷，谢谢。
开发环境：ssm框架+jdk1.7+myeclipse+tomcat+bootstrap；
需求说明：用户根据实际情况，可以添加多条数据提交后台；

form表单我就不截图了，下面是动态添加div的代码；

JSP代码部分
function() { var hrml = "<div id='sztx' ><div class='form-group'><label
class='col-sm-2 control-label'><a class='glyphicon glyphicon-minus-sign'
></a> 阶段性工作内容描述</label><div class='col-sm-10'> <textarea
class='form-control' rows='3' name='task_jdxgzrrms'
id='task_jdxgzrrms'></textarea></div></div> " + "<div class='form-group'><label
class='col-sm-2 control-label'>到期提醒</label><div class='col-md-4'>" + "<input
type='text' class='form-control datetimepicker' id='task_txkssj'
name='task_txkssj'></div><label class='col-sm-2 control-label'>至</label>" +
"<div class='col-md-4'><input type='text' class='form-control datetimepicker'
id='task_txjssj' name='task_txjssj'></div></div>" $("#zdwf_sztx").append(hrml) }
Java代码部分
@RequestMapping(value = "save", method = RequestMethod.POST) public String
task_informations( HttpServletRequest request, @RequestParam(value =
"task_file") MultipartFile file, @RequestParam(value = "task_jdxgzrrms",
required = false) String[] task_jdxgzrrms, @RequestParam(value = "task_txkssj",
required = false) String[] task_txkssj, @RequestParam(value = "task_txjssj",
required = false) String[] task_txjssj, RedirectAttributes redirectAttributes)
{ if (task_jdxgzrrms != null && task_txkssj != null && task_txjssj != null) {
periodicity pd = new periodicity(); for (int i = 0, len =
task_jdxgzrrms.length; i < len; i++) {
pd.setWork_description(task_jdxgzrrms[i]);
pd.setTermination_date(task_txjssj[i]); pd.setStarting_date(task_txkssj[i]);
taskservice.save_periodicity(pd); } }; addMessage(redirectAttributes,
"信息保存成功"); return "redirect:/task/index"; }
