The request sent by the client was syntactically incorrect.(转载)

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。
