1.在spring.xml添加
<!--配置MultipartResolver:用于处理表单中的file-->
<!-- 文件上传配置，这里id的名称固定写法 -->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding" value="UTF-8"></property> <!--请求的编码格式-->
<property name="maxUploadSize" value="102400000"></property> <!--文件最大大小(字节) 1024*1024*50=50M-->
<property name="resolveLazily" value="true"/> <!--resolveLazily属性启用是为了推迟文件解析，以便捕获文件大小异常-->
<property name="uploadTempDir" value="upload"></property> <!--指定上传文件的临时文件夹，请在项目中创建好目录。-->
</bean>2.创建Controller
@Controller
@RequestMapping("/index")
public class indexController {
@RequestMapping(value = "/fileUploadPage.do", method = RequestMethod.POST)
@ResponseBody
public String upload(HttpServletRequest req) throws Exception{
//上传图片
MultipartHttpServletRequest mreq = (MultipartHttpServletRequest)req;
MultipartFile file = mreq.getFile("file");
String fileName = file.getOriginalFilename();
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");
String name=req.getSession().getServletContext().getRealPath("/")+
"upload\\"+sdf.format(new Date())+fileName.substring(fileName.lastIndexOf('.'));
FileOutputStream fos = new FileOutputStream(name);
fos.write(file.getBytes());
fos.flush();
fos.close();
return "/upload/"+sdf.format(new Date())+fileName.substring(fileName.lastIndexOf('.'));
}
}
3.创建index.jsp
<form action="/index/fileUploadPage.do" enctype="multipart/form-data" method="post">
<input type="file" name="file" />
<input type="submit" value="上传"/>
</form>4.测试
4.1 运行界面：
4.2 结果：返回图片存放地址
可以在项目发布路径中查看图片
