两个控制器在Spring Boot中具有不同的最大文件大小 [英] Two controllers have different max file size in Spring Boot
问题描述
在Servlet 3.0规范中,可以创建两个具有不同最大文件大小的servlet并且工作正常。
In Servlet 3.0 specification, two servlets have different max file size can be created and worked fine.
@WebServlet(urlPatterns = { "/ureupload1" })
// 10MB
@MultipartConfig(maxFileSize = 1024 * 1024 * 10)
public class UploadServlet1 extends HttpServlet {
和
@WebServlet(urlPatterns = { "/ureupload2" })
// 30MB
@MultipartConfig(maxFileSize = 1024 * 1024 * 30)
public class UploadServlet2 extends HttpServlet {
如果使用Spring Boot Controller, @MultipartConfig
似乎不工作。
@Controller
@MultipartConfig(maxFileSize = 1024 * 1024 * 10)
public class UploadController1 {
@RequestMapping(value = "/upload1", method = RequestMethod.POST, consumes = "multipart/form-data")
public ModelAndView doPost(@RequestParam("file") MultipartFile file,
如何创建两个具有不同最大文件大小的控制器?
How do I create two controllers have different max file size?
编辑:
其他信息:以下属性位于 application.properties
中,以便设置默认的最大文件大小:
Additional information: The following properties are in application.properties
in order to set default max file size:
spring.http.multipart.max-file-size=30MB
另请参阅: SpringBoot的@MultipartConfig maxFileSize未生效
推荐答案
您需要在application.properties文件中设置默认配置
You need to set a default configuration in application.properties file
spring.http.multipart.max-file-size=30MB
spring.http.multipart.max-request-size=30MB
在你的控制器中你需要抛出 MaxUploadSizeExceededException
基于文件大小的异常:
And in your controller you need to throw MaxUploadSizeExceededException
exception based on the file size :
long limit = 1024 * 1024 * 10;
if (file.getSize() > limit) {
throw new MaxUploadSizeExceededException(limit);
}
