spring boot项目上传文件

严重: Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.web.multipart.MaxUploadSizeExceededException: Maximum upload size exceeded; nested exception is java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.impl.FileSizeLimitExceededException: The field uploadfile exceeds its maximum permitted size of 1048576 bytes.] with root cause
org.apache.tomcat.util.http.fileupload.impl.FileSizeLimitExceededException: The field uploadfile exceeds its maximum permitted size of 1048576 bytes.

 

解决方案呢，要根据SpringBoot的版本来确定，以下列举出了几种情况，可以根据自己项目的SpringBoot版本来对应：把默认的文件的大小限制修改一下即可。以下是我项目中的用到的文件大小限制，改成50MB即可满足我的需求了。

3.1 SpringBoot 1.3.x 之前
multipart.maxFileSize=50Mb
multipart.maxRequestSize=50Mb
3.2 SpringBoot 1.4.x
spring.http.multipart.maxFileSize=50Mb
spring.http.multipart.maxRequestSize=50Mb
3.3 SpringBoot 2.0.x之后
spring.servlet.multipart.max-file-size=50MB
