文件上传依赖：

<dependency>
                <groupId>commons-fileupload</groupId>
                <artifactId>commons-fileupload</artifactId>
                <version>${commons-fileupload.version}</version>
            </dependency>
    
            <dependency>
                <groupId>commons-io</groupId>
                <artifactId>commons-io</artifactId>
                <version>2.6</version>
            </dependency>

在springmvc配置文件中增加解析器：

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
            <property name="defaultEncoding" value="UTF-8"></property>
            <property name="maxUploadSize" value="10485760"></property>
        </bean>

引入JS----jquery.form.js

<script type="text/javascript" src="${pageContext.request.contextPath}/resouces/jquery-1.11.3.min.js"></script>
        
        <script type="text/javascript" src="${pageContext.request.contextPath}/resouces/jqueryExt.js"></script>
        
        <script type="text/javascript" src="${pageContext.request.contextPath}/resouces/jquery.form.js"></script>

页面表单设置：

<form class="form-horizontal"   id="form1" enctype="multipart/form-data">
    
    
                        <div class="row clearfix">
                            <div class="form-group">
                                <label  class="col-sm-1 control-label">编号:</label>
                                <div class="col-md-2 column">

                                    <input type="text" id="Staff_No"   class="form-control" readonly   name="Staff_No" placeholder="">

                        </div>
    
    
    
                        <div class="row clearfix">

                                <div class="col-md-3 column">

                                        <option  value="1">启用</option>

                                    </select>
                                </div>
    
                            </div>

                        <input type="button"    id="saveUploadOrUpdate" data-toggle='modal' data-target='#myModal' class="btn btn-primary" value="保存">
                    </form>

/* 上传文本图片和修改 */
        $(document).on("click","#saveUploadOrUpdate",function(){
            $("#form1").ajaxSubmit({
                url:"userss/saveUploadOrUpdate",
                type:"post",
                contentType:"application/x-www-form-urlencoded; charset=utf-8",
                dataType:"text",
                success:function(data){
                    alert(data);
                    queryUsers(1);
                }
            });
        });

控制器中实现文件上传：

/*添加内容上传图片和修改*/
        @RequestMapping("/saveUploadOrUpdate")
        public void saveTbGoods(@RequestParam("goodsImage") MultipartFile file,StaffInfo tb,HttpServletRequest request,HttpServletResponse response) throws IOException{
            System.out.println("文件："+file+"参数："+tb);
            response.setContentType("text/html;charset=utf-8");
            PrintWriter out=response.getWriter();
            String pathName=transfer(file, request);//调用上传文件transfer方法得到文件路径
            tb.setStaff_Pic(pathName);//添加set文件路径到数据库
            int i=userServices.saveOrUpdateStaffInfo(tb);
            if(i>0){
                out.print("添加成功!");//往前台打印text文本格式
            }else{
                out.print("添加失败!");
            }
        }
        /*上传文件*/
        private String transfer(MultipartFile file,HttpServletRequest request){
            //获取目标文件要存放的目录的绝对路径
            String path=request.getServletContext().getRealPath("/resouces/upload");
            String fileName=file.getOriginalFilename();//获取原始的文件名
            File tranFile=new File(path,fileName);//创建目标文件对象
            if(!tranFile.exists()){
        //如果目录不存在
                tranFile.mkdirs();//创建目录
            }
            try {
                file.transferTo(tranFile);//文件上传
            } catch (IllegalStateException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
    
            return request.getContextPath()+"/resouces/upload/"+fileName;
        }

如何显示：

tr+="<td><img style=' width:90px; height:60px;' src='"+obj.Staff_Pic+"'/></td>";

jsp代码：
