readme maybe need to update ( spring.http property -> spring.servlet property)

[yujin]

i can see two properties at https://github.com/spring-guides/gs-uploading-files#tuning-file-upload-limits part.
spring.http.multipart.max-file-size and spring.http.multipart.max-request-size.

and then i checked spring-boot doc https://docs.spring.io/spring-boot/docs/2.1.0.RELEASE/reference/htmlsingle/#common-application-properties .
there are lots of properties. and i found it is different each other..

# HTTP (HttpProperties)
spring.http.converters.preferred-json-mapper= # Preferred JSON mapper to use for HTTP message conversion. By default, auto-detected according to the environment.
spring.http.encoding.charset=UTF-8 # Charset of HTTP requests and responses. Added to the "Content-Type" header if not set explicitly.
spring.http.encoding.enabled=true # Whether to enable http encoding support.
spring.http.encoding.force= # Whether to force the encoding to the configured charset on HTTP requests and responses.
spring.http.encoding.force-request= # Whether to force the encoding to the configured charset on HTTP requests. Defaults to true when "force" has not been specified.
spring.http.encoding.force-response= # Whether to force the encoding to the configured charset on HTTP responses.
spring.http.encoding.mapping= # Locale in which to encode mapping.
spring.http.log-request-details=false # Whether logging of (potentially sensitive) request details at DEBUG and TRACE level is allowed.

# MULTIPART (MultipartProperties)
spring.servlet.multipart.enabled=true # Whether to enable support of multipart uploads.
spring.servlet.multipart.file-size-threshold=0B # Threshold after which files are written to disk.
spring.servlet.multipart.location= # Intermediate location of uploaded files.
spring.servlet.multipart.max-file-size=1MB # Max file size.
spring.servlet.multipart.max-request-size=10MB # Max request size.
spring.servlet.multipart.resolve-lazily=false # Whether to resolve the multipart request lazily at the time of file or parameter access.
