1、maven工程pom.xml配置如下：

<!-- 文件上传jar -->
<dependency>
      <groupId>commons-io</groupId>
     <artifactId>commons-io</artifactId>
     <version>2.4</version>
   </dependency>
<dependency>
   <groupId>commons-fileupload</groupId>
   <artifactId>commons-fileupload</artifactId>
   <version>1.3</version>
</dependency>

2、applicationContext.xml配置文件里配置如下：

<!-- 支持上传文件 -->  
    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <property name="maxUploadSize" value="1024000"/>
    </bean>

3、form表单里配置：enctype="multipart/form-data"

<form id="defaultFormtest" class="form-horizontal" role="form" action='${pageContext.request.contextPath}/employeeInfoController/insertSelective' method="post" enctype="multipart/form-data">

4、springMVC controller层如下：

public String insertSelective(Employees employees,@RequestParam(value = "file", required = false) MultipartFile file, 
        HttpServletRequest request,HttpServletResponse response) throws Exception{
log.info("前台传输数据："+JSONObject.toJSONString(employees));
try {
 /*response.setContentType("text/html;charset=utf-8");
           out = response.getWriter();*/
          String  path="C:/person/picture";
            String fileName = file.getOriginalFilename(); 
            log.info("图片名字："+JSONObject.toJSONString(fileName));
            System.out.println(fileName);
            System.out.println(path);  
            File targetFile = new File(path, fileName);  
            if(!targetFile.exists()){  
                targetFile.mkdirs();  
            }  
          //保存  
            try {  
                file.transferTo(targetFile);  
            } catch (Exception e) {  
                e.printStackTrace();  
            }  
            /*String url="http://" + request.getServerName() //服务器地址    
                + ":"     
                + request.getServerPort()           //端口号    
                + request.getContextPath()+"/upload/"+fileName;
            System.out.println(request.getContextPath()+"/upload/"+fileName);
            System.out.println(url);*/
            String s=path+'/'+fileName;
            System.out.println(s);
            employees.setYgYgzp(s);
            employeeInfoService.insertSelective(employees);
            return "employeesInfo/addEmployees";
            //out.print("<script language=\"javascript\">window.location.href='http://192.168.1.105:18080/ybzt/views/employeesInfo/addEmployees.jsp'</script>");
            //System.out.println("数据："+ygNm);
            //response.reset();
} catch (Exception e) {
 throw new Exception(e.getMessage());
}
