您可以
CommonsMultipartResolver在控制器中自动接线并在运行时在那里更新属性。
例如：
@Controllerpublic class MyController { @Autowired private CommonsMultipartResolver multipartResolver; @RequestMapping(value = "/setMaxUploadSize", method = RequestMethod.GET) public ModelAndView setMaxUploadSize() { ... multipartResolver.setMaxUploadSize(5000); ... }}
