在處理表單類數據的時候，之前處理過一個表單裏面有20條類似的數據，針對這些數據都是通過一個一個的變量進行輸入的，一條數據有5個值，20條數據100個值，在controller中的參數中設置100個參數，哦，my god，好讓人崩潰，但是確實就這麼幹了一回，下面是寫的參數:

表單處理主要分爲兩部分，一部分是表單的展示，一部分是處理表單的輸入；
1.處理表單的輸入
1.1.註解形式的參數接收
1.1.1. HttpServletRequest可以直接定義在參數的列表，通過該請求可以傳遞參數
@Override
public int setAllIni(HttpServletRequest request) {
int ret = 1;
Map<String, Object> map = new HashMap<String,Object>();
//續保相關
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;
}可以從HttpServletRequest 取出“xuBao”屬性，然後進行操作！
1.1.2. 在參數列表上直接定義要接收的參數名稱，只要參數名稱能匹配的上就能接收所傳過來的數據, 可以自動轉換成參數列表裏面的類型，注意的是值與類型之間是可以轉換的
1.1.2.1,傳遞多種不同類型的參數：
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("輸入的參數：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 "無效的參數設置！";
}
String result = carTypeMockService.vehicleInput(citycode,licenseNo,licenseOwner,frameNo,engineNo,vehivleName,enrollDate,seatCount);
return result;
}1.1.2.2.傳遞數組
url：http://localhost/mvc/test/toPerson2.do?name=tom&name=jack
/**
* 對數組的接收，定義爲同名即可
*/
@RequestMapping("/toPerson2.do")
public String toPerson2(String[] name) {
for (String result : name) {
System.out.println(result);
}
return "jsp1/index";
} 1.1.2.3.傳遞自定義對象（可多個）
url：http://localhost/mvc/test/toPerson3.do？name=zhangsan&age=14&address=china&birthday=2000-2-11
User 定義的屬性有：name,age，並且有各自屬性的對應的set方法以及toString方法
Person定義的屬性有：name,age.address,birthday，並且有各自屬性的對應的set方法以及toString方法
/**
*
* 傳遞的參數的名字必須要與實體類的屬性set方法後面的字符串匹配的上才能接收到參數，首字符的大小寫不區分
* 請求中傳的參數只要是能和參數列表裏面的變量名或者實體裏面的set後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請求
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: '批量設置成功',
buttons: {
ok: {
label: '確定',
className: 'btn-myStyle',
}
},
callback: function() {
window.location.reload();
}
});
}else{
bootbox.alert("批量設置失敗");
}
}
});1.3.表單提交
