io.undertow.server.RequestTooBigException: UT000020 Connection terminated as request was larger than xxxx

修改yaml文件中关于undertow的配置项

server:
  undertow:
    # HTTP POST请求最大的大小
    # 默认0，无限制
    max-http-post-size: ${SERVER_UNDERTOW_MAX_HTTP_POST_SIZE:2GB}

修改后依旧无效,请检查spring.servlet.multipart下的配置

如果存在max-file-size配置,则undertow中配置的值就会失效,会以该max-file-size为准

spring:
  servlet:
    multipart:
      # 文件最大限制
      max-file-size: ${MEMBER_AVATAR_MAX_FILE_SIZE:2048MB}
