У нас есть приложение Spring Cloud, использующее Eureka в качестве обнаружения службы, Config Service и WebFlux. Сервис отлично работает с Spring Cloud Hoxton.SR4, но не работает с Hoxton.SR5 при запуске приложения во время выборки данных из Eureka. Если у Eureka небольшое количество зарегистрированных приложений (например, 30), оно работает нормально, но если у него около 250 сервисов, он не работает со следующим исключением:
DataBufferLimitException: Exceeded limit on max bytes to buffer : 262144 Error has been observed at the following site(s): checkpoint ⇢ Body from GET http://eureka.xxx.com:8080/eureka/apps/?regions=us-east-1.
Если мы удалите WebFlux из пути к классам, он также отлично работает даже с Hoxton.SR5. Я предоставил воспроизводимую проблему на github (но для воспроизведения нам нужно подключиться к Eureka, имеющему несколько сотен зарегистрированных приложений). Я также видел проблему с аналогичным исключением , в их случае проблема возникла на стороне контроллера, но в нашем случае при запуске приложения и свойство spring.codec.max-in-memory-size здесь не работает.
