У меня есть RestClient, вызывающий запросы GET для службы Spring (сервер), этот сервер принимает запросы HTTP2, и я получаю 302 в качестве ответа. Как отправлять запросы Http2 с помощью Spring RestTemplate.
Exception in thread "main" org.springframework.web.client.ResourceAccessException: I/O error on GET request for "https://example.com/static/mobile/get-token": unexpected end of stream on Connection{domain.com:443, proxy=DIRECT hostAddress=example.com cipherSuite=TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 protocol=http/1.1}; nested exception is java.io.IOException: unexpected end of stream on Connection{example.com:443, proxy=DIRECT hostAddress=example.com cipherSuite=TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 protocol=http/1.1}
