一，html脚本
<script type="text/javascript">
???$(function() {
???$(".btn-submit").click(function() {
???var url = ‘${rc.contextPath}/wxFfanApply.htm?method=save‘;
???var param = $("#submitForm").serialize();
???$.ajax({
???????????url: url,
???type: ‘POST‘,
???dataType: ‘json‘,
???????data: param,
???async: false,
???success: function(data){
???if ("000" == data.code) {
???alert("保存成功");
???var url = ‘${rc.contextPath}/wxFfanApply.htm?method=preToMain‘;
???????document.getElementById(‘submitForm‘).action = url;
???????document.getElementById(‘submitForm‘).submit();
???} else {
???alert("保存出现异常，请重试");
???}
???}
???});
???});
???});
???</script>

二，java代码
2.1，代码一
public void save(HttpServletRequest request, HttpServletResponse response) {
logger.info("save info begin...");
Map<String, Object> result = new HashMap<String, Object>();
try {
String wxOpenId = request.getParameter("wxOpenId");
String applyId = request.getParameter("applyId");
String wxModuleType = request.getParameter("wxModuleType");
if (StringUtil.isEmpty(wxOpenId) || StringUtil.isEmpty(applyId)
|| StringUtil.isEmpty(wxModuleType)) {
result.put("code", "001");
result.put("desc", "必填参数为空");
super.toJson(result, response);
return;
}
// 获取request里的所有参数，作为orderParam
String paramJson = packageOrderParam(request);
}
2.2，代码二
protected String packageOrderParam(HttpServletRequest request)
throws Exception {
Map<String, Object> paramMap = getParameterMap(request);
String selCity = request.getParameter("selCity");
if(StringUtil.isNotEmpty(selCity)){
String [] arr = selCity.split("\\s+");
String province=null;
String city=null;
String country=null;
for (int i = 0; i < arr.length; i++) {
???switch (i) { ?
???case 0: ?
???province = arr[i]; ?
???????break; ?
???case 1: ?
???city ?= arr[i]; ?
???????break; ?
???case 2: ?
???country= arr[i]; ?
???????break; ?
???default: ?
???????break; ?
???}
}
paramMap.put("province", province);
paramMap.put("city", city);
paramMap.put("country", country);
}
return JsonUtils.map2Json(paramMap);
}
???
2.3，代码三
@SuppressWarnings("unchecked")
public Map<String, Object> getParameterMap(HttpServletRequest request) {
Map<String, Object> resultMap = new HashMap<String, Object>();
Map<String, String[]> map = request.getParameterMap();
Set<Map.Entry<String, String[]>> set = map.entrySet();
Iterator<Map.Entry<String, String[]>> it = set.iterator();
while (it.hasNext()) {
Map.Entry<String, String[]> entry = (Map.Entry<String, String[]>) it.next();
for (String v : (String[]) entry.getValue()) {
resultMap.put(entry.getKey(), v);
}
}
return resultMap;
}
前台序列化传过来的值，后台获取之后封装到map当中，让后在转化成json格式，最后在把json里面的参数里面的某一个值进行分割，最后在存到json格式的数据中去。
