Receive HTTP Stream in Spring Boot - spring

Question

i want to receive a HTTP Stream in SpringBoot but the InputStream of HttpServletRequest seems not to be an endless HTTP Stream and only contains the Content of first HTTP Body.
I want to process a chuncked HTTP Stream in SpringBoot on which is puhed some Value String from time to time.
Currently I tried something like this in a controller:
#Override
public void test(HttpServletRequest request,
HttpServletResponse response) {
System.out.println("StreamStart");
try {
byte[] buffer = new byte[1024];
while(true){
int len = request.getInputStream().read(buffer);
if(len!=-1) {
System.out.println("Len: " + len);
System.out.println(new String(buffer));
}
Thread.sleep(500);
}
}
catch(Exception x){
x.printStackTrace();
}
System.out.println("StreamEnd");
}
However the first Request Body after the header works, but the second does not appear in my Controller.
Does SpringBoot cancles the connection or the stream?
Can I have access to the complete HTTP Input stream to get my values from it?

Maybe Multipart request would be usefull for you?
That way you can recieve multiple parts of data
https://www.w3.org/Protocols/rfc1341/7_2_Multipart.html
Example:
#PostMapping("/upload")
public void uploadStream(#RequestParam MultipartFile[] multipartFiles){
for(MultipartFile multipartFile:multipartFiles){
try {
InputStream inputStream = multipartFile.getInputStream();
} catch (IOException e) {
e.printStackTrace();
}
}
}
