alpha-module

spring-cloud-gateway providing a rest api: /hello

# run
java -jar .jar-output/alpha-module.jar

curl 'http://localhost:8082/hello
# return 'hello world'

beta-module

simple webflux-application providing a rest api: /beta/hello

# run
java -jar .jar-output/beta-module.jar

curl 'http://localhost:8081/beta/hello
# return 'from beta'

Problem

access /beta/hello through gateway with discovery will be block. only occur when spring.threads.virtual.enabled=true and running as boot-jar.

curl 'http://localhost:8082/beta/hello
# should return 'from beta'
