spring boot上传文件限制大小

今天做上传文件时报错了，超出默认的上传大小了，以前只在xml中配置过spring mvc的大小设置，spring boot中还没设置过。

org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; nested exception is java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException: the request was rejected because its size (24051324) exceeds the configured maximum (10485760)

解决方案如下：

要么就还是采用xml配置，然后spring boot中导入xml

或者在application.properties中增加如下配置：

1.4版本之前：

multipart.maxFileSize=1024MB
multipart.maxRequestSize=1024MB

1.4版本后：

spring.http.multipart.maxFileSize=1024MB
spring.http.multipart.maxRequestSize=1024MB
