SpringBoot文件上传大小限制
最近项目中使用SpringBoot开发文件上传功能,后台异常如下:
org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException:
the request was rejected because its size (20192551) exceeds the configured maximum (10485760)
意即文件大小超出默认最大值(10485760=10Mb)
官方文档配置如下:
# MULTIPART (MultipartProperties) spring.servlet.multipart.enabled=true # Whether to enable support of multipart uploads. spring.servlet.multipart.file-size-threshold=0 # Threshold after which files are written to disk. Values can use the suffixes "MB" or "KB" to indicate megabytes or kilobytes, respectively. spring.servlet.multipart.location= # Intermediate location of uploaded files. spring.servlet.multipart.max-file-size=1MB # Max file size. Values can use the suffixes "MB" or "KB" to indicate megabytes or kilobytes, respectively. spring.servlet.multipart.max-request-size=10MB # Max request size. Values can use the suffixes "MB" or "KB" to indicate megabytes or kilobytes, respectively. spring.servlet.multipart.resolve-lazily=false # Whether to resolve the multipart request lazily at the time of file or parameter access.所以说,在application.properties配置文件中,修改该默认值即可:
spring.servlet.multipart.max-file-size=30MB # Max file size. Values can use the suffixes "MB" or "KB" to indicate megabytes or kilobytes, respectively. spring.servlet.multipart.max-request-size=50MB # Max request size. Values can use the suffixes "MB" or "KB" to indicate megabytes or kilobytes, respectively.问题解决;阅读更多
