Hello, @wzwllu Thanks for submitting the PR. The tests will fail on main currently due to necessary changes waiting for merge in Netflix/Eureka. Please submit your PR against the 3.1.x branch instead of main.

Please modify so that the values are configurable via .properties files, for example by adding a static class dedicated to Apache Client properties in EurekaClientConfigBean. Also, make sure the default values are set up there.
