问题:springcloud gateway 框架做的一个项目,接口再请求时,出现上传数据小不会抛出问题,一旦请求报文数据大就会抛出问题

找了好多资料,尝试了很多方法,也更改配置了

spring:
  codec:
    max-in-memory-size: 50MB

然而并没有什么卵用

解决方式:我原来是从springboot2.2.0升级到springboot2.2.1,降回去就好了,亲测有效,没有再出现上边的问题

<parent>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-parent</artifactId>
	<version>2.2.0.RELEASE</version>
	<relativePath/> <!-- lookup parent from repository -->
</parent>
