这个错误是SpringMVC报出来的,见到它意味着html/jsp页面的控件名称 和 controller里函数的参数不符。
好比界面有个这样的form
<form name="form1" action="uploadDocument.html" method="post" ENCTYPE="multipart/form-data"> <div class="form" > <p> <span class="req"><input id="remarkTxt" name="remarkTxt" class="field size4" title="Enter the date" /></span> <label>Remark: <span>(The brief introduction of the file)</span></label> </p> <p> <span class="req"><input type="file" name="uploadFileCtrl" class="field size4" title="Choose the file" /></span> <label>Upload file: <span>(Click browse to choose)</span></label> </p> </div> <div class="buttons"> <input id="queryBtn" type="button" class="button" value="Submit" /> </div> </form>
而对应的函数参数应该这样写:
@RequestMapping(value="/uploadDocument") public String uploadDocument( @RequestParam("remarkTxt") String remark, @RequestParam("uploadFileCtrl") MultipartFile file, HttpServletRequest request, HttpServletResponse response){ .... }}
注意上述粗体字的一一对应关系。
