spring-boot上传

前端

<form action="./batchQuery" method="post" enctype="multipart/form-data">   <input type="file" name="file" />   <input type="submit" value="上传" /> </form>

后端,在Controller中接收

@RequestMapping(value="/upload", method=RequestMethod.POST) public String upload(@RequestParam("file") MultipartFile file){}

在SpringMVC中需要配置一个MultipartResovr如下

<bean id="multipartResolver" class="org.springframework.web.multipart.comons.CommonsMultipartResolver">   <!--允许文件上传大小,单位:字节-->   <property name="maxUploadSize" value="1024000"> </bean>

在Springboot中改如何设置,如下

@Bean public MultipartConfigElement multipartConfigElement() {     MultiPartConfigFactory factory = new MultiPartConfigFactory();     factory.setMaxFileSize("10240KB");     return factory.createMultipartConfig(); }

springboot默认大小是

1048576 bytes
