spring如何处理表单数据

        在处理表单类数据的时候，之前处理过一个表单里面有20条类似的数据，针对这些数据都是通过一个一个的变量进行输入的，一条数据有5个值，20条数据100个值，在controller中的参数中设置100个参数，哦，my god，好让人崩溃，但是确实就这么干了一回，下面是写的参数:

说实话，不想用类似的方式再写一个类似的功能了，之后查了下，发现在spring里面有更好的处理方式，就是通过提交表单的方法，所以这里仔细的研究一下如果通过表单提交该如何处理类似的问题；

        表单处理主要分为两部分，一部分是表单的展示，一部分是处理表单的输入；

1.处理表单的输入

1.1.注解形式的参数接收

1.1.1. HttpServletRequest可以直接定义在参数的列表，通过该请求可以传递参数

@Override
public int setAllIni(HttpServletRequest request) {
int ret = 1;
Map<String, Object> map = new HashMap<String,Object>();
//续保相关
map.put("iniName", "xuBaoZaiBeiPingAn");
map.put("iniValue", request.getParameter("xuBao"));
ret = zaiBeiDao.updateIniZaiBei(map);
if(ret != 1){
return 0;
}
map.put("iniName", "xuBaoZaiBeiPingAnDelayTime");
map.put("iniValue", request.getParameter("xuBaoDelayTime"));
ret = zaiBeiDao.updateIniZaiBei(map);
if(ret != 1){
return 0;
}

可以从HttpServletRequest 取出“xuBao”属性，然后进行操作！
1.1.2. 在参数列表上直接定义要接收的参数名称，只要参数名称能匹配的上就能接收所传过来的数据, 可以自动转换成参数列表里面的类型，注意的是值与类型之间是可以转换的


1.1.2.1,传递多种不同类型的参数：

url：http://baoxian.qa.ms.netease.com/vehicle/input?city_code=23223&license_no=12345&license_owner=kang&frame_no=9090&engine_no=8080&vehicle_name=4343&enroll_date=2015-08-07&seat_count=6

@RequestMapping(value="/vehicle/input",method=RequestMethod.POST)
@ResponseBody
public String vehicleInput(@RequestParam("city_code") String citycode,@RequestParam("license_no") String licenseNo,
@RequestParam(value="license_owner",required=false) String licenseOwner, @RequestParam(value="frame_no",required=false) String frameNo,
@RequestParam(value="engine_no",required=false) String engineNo,@RequestParam(value="vehicle_name",required=false) String vehivleName,
@RequestParam(value="enroll_date",required=false) String enrollDate,@RequestParam(value="seat_count",required=false) String seatCount){
LogConstant.runLog.info("输入的参数：citycode：" + citycode + " license_no:"
+ licenseNo + " license_owner:" + licenseOwner + " frame_no:"
+ frameNo + " engine_no:" + engineNo + " vehicle_name:"
+ vehivleName + " enroll_date:" + enrollDate + " seat_count:"
+ seatCount);
if(StringUtils.isEmpty(citycode) || StringUtils.isEmpty(licenseNo) || StringUtils.isEmpty(licenseOwner)){
return "无效的参数设置！";
}
String result = carTypeMockService.vehicleInput(citycode,licenseNo,licenseOwner,frameNo,engineNo,vehivleName,enrollDate,seatCount);
return result;
}

1.1.2.2.传递数组
[b]url：http://localhost/mvc/test/toPerson2.do?name=tom&name=jack  



/**
* 对数组的接收，定义为同名即可
*/
@RequestMapping("/toPerson2.do")
public String toPerson2(String[] name) {
for (String result : name) {
System.out.println(result);
}
return "jsp1/index";
}
1.1.2.3.[b]传递自定义对象（可多个）[/b]



url：http://localhost/mvc/test/toPerson3.do？name=zhangsan&age=14&address=china&birthday=2000-2-11

 User 定义的属性有：name,age，并且有各自属性的对应的set方法以及toString方法

 Person定义的属性有：name,age.address,birthday，并且有各自属性的对应的set方法以及toString方法

/**
*
* 传递的参数的名字必须要与实体类的属性set方法后面的字符串匹配的上才能接收到参数，首字符的大小写不区分
* 请求中传的参数只要是能和参数列表里面的变量名或者实体里面的set后面的字符串匹配的上就能接收到
*
*/
@RequestMapping("/toPerson3.do")
public String toPerson3(Person person, User user) {
System.out.println(person);
System.out.println(user);
return "jsp1/index";
}

1.2.ajax请求
function setAllIni(){
var data = {};
data.xuBao = $("#setXuBao").val();
data.xuBaoDelayTime = $("#xuBaoDelayTime").val();

......

$.ajax({
url: '/zaiBeiPingAn/setAllIni.html',
type: 'POST',
data: data,
dataType: 'json',
async: false,
success: function(json){
if(json.retCode=="200"){
bootbox.alert({
message: '批量设置成功',
buttons: {
ok: {
label: '确定',
className: 'btn-myStyle',
}
},
callback: function() {
window.location.reload();
}
});
}else{
bootbox.alert("批量设置失败");
}
}
});里面只是显示了表单里面的一条数据，其他数据格式类似；
1.3.表单提交

表单ftl页面:

<#include "../../inc/core.ftl">
<@htmHead title="保险Mock平台"
otherJs=["/js/insurance/pingan/zaiBei.js", "/js/common/bootbox.js", "/js/date/WdatePicker.js"]

<@htmlNavHead />
<div id="page-wrapper">

<h1 class="page-header">灾备测试</h1>
</div>
</div>
<br><br>

<div class="row">
<div class="col-lg-12">
<div class="col-lg-3">
<div class="form-group input-group">

<input id="xuBaoDelayTime" class="form-control">

</div>

<div class="row">

<option value="delay">延时</option>
<option value="failure">失败</option>
<option value="session">session失效</option>
</select>
</div>
</div>

<div class="col-lg-3" id="sr-delay" style="display: none;">
<div class="form-group input-group">
<span class="input-group-addon">延时时长</span>
<input id="shengRiDelayTime" class="form-control">
</div>
</div>
<button class="btn btn-primary" type="button" onClick="setZaiBei('shengRi')">设置</button>
</div>
</div>
<div class="row">
<div class="col-lg-12">
<button class="btn btn-primary" type="button" onClick="setAllIni()">批量设置</button>
<button class="btn btn-primary" type="button" onClick="setBackUp()">还原设置</button>
</div>
</div>

</div>

对象java方法:
@RequestMapping("/zaiBeiPingAn/setAllIni")
@ResponseBody
public Map<String, Object> setAllIni(HttpServletRequest request, Model model){

Map<String, Object> retMap = new HashMap<String, Object>();
int ret = zaiBeiService.setAllIni(request);

if(ret == 1){
retMap.put("retCode", 200);
retMap.put("retDesc", "批量设置成功");
}else{
retMap.put("retCode", -1);
retMap.put("retDesc", "批量设置失败");
}
return retMap;
}

@Override
public int setAllIni(HttpServletRequest request) {
int ret = 1;
Map<String, Object> map = new HashMap<String,Object>();
//续保相关
map.put("iniName", "xuBaoZaiBeiPingAn");
map.put("iniValue", request.getParameter("xuBao"));
ret = zaiBeiDao.updateIniZaiBei(map);
if(ret != 1){
return 0;
}

map.put("iniName", "xuBaoZaiBeiPingAnDelayTime");
map.put("iniValue", request.getParameter("xuBaoDelayTime"));
ret = zaiBeiDao.updateIniZaiBei(map);
if(ret != 1){
return 0;
}

//生日相关
map.put("iniName", "shengRiZaiBeiPingAn");
map.put("iniValue", request.getParameter("shengRi"));
ret = zaiBeiDao.updateIniZaiBei(map);
if(ret != 1){
return 0;
}

map.put("iniName", "shengRiZaiBeiPingAnDelayTime");
map.put("iniValue", request.getParameter("shengRiDelayTime"));
ret = zaiBeiDao.updateIniZaiBei(map);
if(ret != 1){
return 0;
}

return ret;
}

这里描述了两条记录的情况，我们来看下运行情况:
