Наконец, я нашел решение, много раз копав исходный код. Я использую версию Camden.SR5, которая будет вызывать eureka-client-1.4.12.
Если вы укажете EurekaJerseyClient в DiscoveryClientOptionalArgs, то клиент Discovery не будет инициализировать клиент по умолчанию. Часть кода из класса DiscoveryClient.
private void scheduleServerEndpointTask(EurekaTransport eurekaTransport,
DiscoveryClientOptionalArgs args) {
...
EurekaJerseyClient providedJerseyClient = args == null
? null
: args.eurekaJerseyClient;
eurekaTransport.transportClientFactory = providedJerseyClient == null
? TransportClientFactories.newTransportClientFactory(clientConfig, additionalFilters, applicationInfoManager.getInfo())
: TransportClientFactories.newTransportClientFactory(additionalFilters, providedJerseyClient);
...
}
Затем я добавляю класс для создания bean-компонента DiscoveryClientOptionalArgs.

@Bean
public DiscoveryClient.DiscoveryClientOptionalArgs discoveryClientOptionalArgs(){
if(!defaultSslConfig.isFinish()){
log.warn("Default SSLContext might not have been updated! Please check!");
}
DiscoveryClient.DiscoveryClientOptionalArgs args = new DiscoveryClient.DiscoveryClientOptionalArgs();
CustomEurekaJerseyClientBuilder clientBuilder = new CustomEurekaJerseyClientBuilder()
.withClientName("DiscoveryClient-HTTPClient-Custom")
.withUserAgent("Java-EurekaClient")
.withConnectionTimeout(config.getEurekaServerConnectTimeoutSeconds() * 1000)

.withConnectionIdleTimeout(config.getEurekaConnectionIdleTimeoutSeconds() * 1000)
.withEncoderWrapper(CodecWrappers.getEncoder(config.getEncoderName()))
.withDecoderWrapper(CodecWrappers.resolveDecoder(config.getDecoderName(), config.getClientDataAccept()));
if (defaultZone.startsWith("https://")) {
clientBuilder.withSystemSSLConfiguration();
}
EurekaJerseyClient jerseyClient = clientBuilder.build();
args.setEurekaJerseyClient(jerseyClient);//Provide custom EurekaJerseyClient to override default one
return args;
}
}
Чтобы убедиться, что мой пользовательский EurekaJerseyClient работает нормально, я раздвоил код из EurekaJerseyClientImpl и внес некоторые изменения.

Надеюсь, это поможет тем, кому, как и мне, нелегко импортировать сертификат в производственную JVM.
