1. 解释inputstream has already been read错误的含义 InputStream是Java中用于读取字节数据的抽象类。当InputStream被读取后,其内部的位置指针(或称为“读取指针”)会前进,直到到达流的末尾。如果尝试再次读取已经读取过的InputStream,且没有重置位置指针,那么将无法得到任何数据(因为位置指针已经在流的末尾),从而引发...

Know the offset and know that Spring will handle a ranged request, so that I can open my stream to origin with that offset as well. I can of course just read the range request and know the offset as I do it now, but then it is from the API totally unintuitive that Spring will wan...

文档建议使用ByteArrayResource将内容缓存在内存中，而不是InputStreamResource。https://docs.spring.io/...

java InputStream read方法内部有一个,postion,标志当前流读取到的位置,每读取一次,位置就会移动一次,如果读到最后,InputStream.read方法会返回-1,标志已经读取完了,如果想再次读取,可以调用inputstream.reset方法,position就会移动到上次调用mark的位置,mark默认是0,所以就能从头再读了。
I feel that this is not a problem with the MultiPartInputStreamParser, but rather that the Request.extractContentParameters() not being aware that the InputStream has been completely read already. Perhaps the extractContentParameters() should inspect the _inputState==NONE to verify proper behavior...
