Project scenario :
SpringBoot Upload files
Problem description
SpringBoot File upload interface , The following exceptions will be reported under the default configuration :
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 file exceeds its maximum permitted size of 1048576 bytes.

Cause analysis :
From the abnormal information, we can see , The maximum upload size overflowed , The maximum upload size is :1048576 bytes
That is to say 1M
.
from SpringBoot You can find the automatic configuration class about file upload in the automatic configuration class of :org.springframework.boot.autoconfigure.web.servlet.MultipartAutoConfiguration
:
...
@EnableConfigurationProperties(MultipartProperties.class)
public class MultipartAutoConfiguration {
...
}
You can see that this configuration class loads the attribute configuration class :MultipartProperties
:
@ConfigurationProperties(prefix = "spring.servlet.multipart", ignoreUnknownFields = false)
public class MultipartProperties {
/** * Max file size. */
private DataSize maxFileSize = DataSize.ofMegabytes(1);
/** * Max request size. */
private DataSize maxRequestSize = DataSize.ofMegabytes(10);
/** * Threshold after which files are written to disk. */
private DataSize fileSizeThreshold = DataSize.ofBytes(0);
...
public DataSize getMaxFileSize() {
return this.maxFileSize;
}
public void setMaxFileSize(DataSize maxFileSize) {
this.maxFileSize = maxFileSize;
}
}
You can see from the source code , If we don't set the maximum file size maxFileSize
Words , Will give a default value , The default is 1048576 bytes
:
public static DataSize ofMegabytes(long megabytes) {
return new DataSize(Math.multiplyExact(megabytes, 1048576L));
}
Solution :
The default file upload size limit certainly does not meet our production needs , So we need to set the above MultipartProperties
Medium maxFileSize
Value :
spring:
servlet:
multipart:
max-file-size: 50MB
