在SpringBoot中上传大于1MB的文件时,会提示如下异常:

在Spring Boot2.0之后的版本中请求文件的默认大小时有限制的,如下图:
Spring Boot2.0之后的版本请求的文件默认大小

max-file-size:设置单个文件的大小;
max-request-size:设置单次请求的文件的总大小

特别说明:
在Spring Boot1.4版本后配置更改为:
Spring Boot1.4版本请求的文件默认大小

如果需要可以修改下面的参数到.yml文件中,这里就以SpringBoot 2.0为例:

spring:
  servlet:
    multipart:
      max-file-size: 5Mb
      max-request-size: 10Mb
  ......
