Changing CommonsMultipartResolver's maxUploadSize during runtime

Pergunta
I am using a CommonsMultipartResolver for file upload.
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" >
<!-- specify maximum file size in bytes -->
<property name="maxUploadSize" value="100000"/>
</bean
I want to be able to change its property maxUploadSize at runtime (so that the size may be changed by the administrator). What is the best way to do this please?
Solução
You can autowire CommonsMultipartResolver
in your controller and update the property there at runtime.
For example:
@Controller
public class MyController {
@Autowired
private CommonsMultipartResolver multipartResolver;
@RequestMapping(value = "/setMaxUploadSize", method = RequestMethod.GET)
public ModelAndView setMaxUploadSize() {
...
multipartResolver.setMaxUploadSize(5000);
...
}
}
