文件上传依赖：

 <!-- 文件上传组件 -->
        <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：

<!--SpringMvc文件上传时,需要配置MultipartResolver处理器  -->
    <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

<!--最基础jQuery.js都是基于这个  -->
    <script type="text/javascript" src="${pageContext.request.contextPath}/resouces/jquery-1.11.3.min.js"></script>
    <!-- 异步转换参数js -->
    <script type="text/javascript" src="${pageContext.request.contextPath}/resouces/jqueryExt.js"></script>
    <!-- 上传文件js -->
    <script type="text/javascript" src="${pageContext.request.contextPath}/resouces/jquery.form.js"></script>

页面表单设置：

<!--form提交表单  -->
                <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">
                                <!--编号  -->

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

                            <label class="col-sm-1 control-label">工号:</label>
                            <div class="col-md-2 column">

                            </div>

                            <label  class="col-sm-1 control-label">姓名:</label>
                            <div class="col-md-2 column">
                                <input type="text" id="Staff_Name" class="form-control"  name="Staff_Name" placeholder="请输入姓名" >

                            <label  class="col-sm-1 control-label">状态:</label>
                            <div class="col-md-2 column">
                                <select class="form-control" name="Staff_Enable">

                                </select>
                            </div>

                        </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：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8" isELIgnored="false"%>
<%
    String path = request.getContextPath();
    String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
