POST异步跳转或下载方案（动态创建表单提交）

 var form=$("<form>");//定义一个form表单
            form.attr("style","display:none");
            form.attr("target","");
            form.attr("method","post");
            form.attr("action","/crm/salesData/postCRExportExcel/"+_this.queryCond.calType);
            var input1=$("<input>");
            input1.attr("type","hidden");
            input1.attr("name","ls_salesDataCRExportVOStr");
            input1.attr("value",JSON.stringify(_this.SalesDataCRExportList));
            $("body").append(form);//将表单放置在web中
            form.append(input1);
            form.submit();//表单提交

可能会遇到Spring不支持表单提交方案，参见
The problem is that when we use application/x-www-form-urlencoded, Spring doesn't understand it as a RequestBody. So, if we want to use this we must remove the @RequestBody annotation.

Then try the following:

@RequestMapping(value = "/{email}/authenticate", method = RequestMethod.POST,
        consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE, 
        produces = {MediaType.APPLICATION_ATOM_XML_VALUE, MediaType.APPLICATION_JSON_VALUE})
public @ResponseBody  Representation authenticate(@PathVariable("email") String anEmailAddress, MultiValueMap paramMap) throws Exception {
   if(paramMap == null && paramMap.get("password") == null) {
        throw new IllegalArgumentException("Password not provided");
    }
    return null;
}
