我正在使用SpringBoot构建一个简单的API。通过Request estBody接收输入并打印出来…

但是，随着Request estBody大小的增加，会发生以下错误。它不是无条件发生的，有时会成功…

Spring Boot配置包括

1. Spring。ser v let。多部分。最大-文件-大小
2. Spring。ser v let。多部分。最大-请求-大小
3. server. max-超文本传输协议-form-post-size
4. 服务器。最大-燕子-大小
5. 服务器. tomcat.连接-超时

和nginx我修改了所有设置。

随着时间的推移没有发生错误，但是我一发送POST请求就发生了错误。小身体仍然工作得很好…

客户端将图像文件编码为Base64，并将编码结果作为JSON传递。如果Base64的长度较短，则会进行处理，没有任何问题，但如果长度较长，则会出现相应的错误。

如果你有任何相关经验，我征求如何修复它的建议。
