忽略网络接口

配置忽略了 docker0 接口和所有以开头的接口 veth

spring:
  cloud:
    inetutils:
      ignoredInterfaces:
        - docker0
        - veth.*
通过使用正则表达式列表强制仅使用指定的网络地址
spring:
  cloud:
    inetutils:
      preferredNetworks:
        - 192.168
        - 10.0
强制仅使用站点本地地址
spring:
  cloud:
    inetutils:
      useOnlySiteLocalInterfaces: true
HTTP客户端工厂
Spring Cloud Commons 提供了用于创建 Apache HTTP 客户端 ( ApacheHttpClientFactory) 和 OK HTTP 客户端 ( OkHttpClientFactory) 的 bean。仅当OkHttpClientFactoryOK HTTP jar 在类路径上时才会创建 bean。此外，Spring Cloud Commons 提供了用于创建两个客户端使用的连接管理器的 bean：ApacheHttpClientConnectionManagerFactory用于 Apache HTTP 客户端和OkHttpClientConnectionPoolFactoryOK HTTP 客户端。如果您想自定义如何在下游项目中创建 HTTP 客户端，您可以提供自己的这些 bean 实现。另外，如果你提供一个HttpClientBuilderor类型的 bean OkHttpClient.Builder，默认工厂使用这些构建器作为构建器返回到下游项目的基础。您还可以通过设置spring.cloud.httpclientfactories.apache.enabled或spring.cloud.httpclientfactories.ok.enabled来禁用这些 bean 的创建false。
添加gradle配置，自动启用OK HTTP 客户端
implementation 'com.squareup.okhttp3:okhttp'
Spring Cloud LoadBalancer缓存
如果您com.github.ben-manes.caffeine:caffeine在类路径中有，将使用基于 Caffeine 的实现。有关如何配置它的信息，请参阅LoadBalancerCacheConfiguration部分。
如果您使用的是咖啡因，您还可以通过在属性中传递您自己的咖啡因规范来覆盖 LoadBalancer 的默认咖啡因缓存设置。spring.cloud.loadbalancer.cache.caffeine.spec
警告：传递您自己的 Caffeine 规范将覆盖任何其他 LoadBalancerCache 设置，包括常规 LoadBalancer 缓存配置字段，例如ttl和capacity。
默认设置包括ttl设置为35s，默认设置initialCapacity为256.
要使用 Caffeine 而不是默认缓存，请将com.github.ben-manes.caffeine:caffeine依赖项添加到类路径。CaffeineCacheManager需要添加org.springframework:spring-context-support依赖。
常见应用程序属性
Name Default Description
spring.cloud.compatibility-verifier.compatible-boot-versions 2.6.x Default accepted versions for the Spring Boot dependency. You can set {@code x} for the patch version if you don’t want to specify a concrete value. Example: {@code 3.4.x}
spring.cloud.compatibility-verifier.enabled false Enables creation of Spring Cloud compatibility verification.
spring.cloud.config.allow-override true Flag to indicate that {@link #isOverrideSystemProperties() systemPropertiesOverride} can be used. Set to false to prevent users from changing the default accidentally. Default true.
spring.cloud.config.override-none false Flag to indicate that when {@link #setAllowOverride(boolean) allowOverride} is true, external properties should take lowest priority and should not override any existing property sources (including local config files). Default false.
spring.cloud.config.override-system-properties true Flag to indicate that the external properties should override system properties. Default true.

spring.cloud.inetutils.ignored-interfaces List of Java regular expressions for network interfaces that will be ignored.
spring.cloud.inetutils.preferred-networks List of Java regular expressions for network addresses that will be preferred.
spring.cloud.inetutils.timeout-seconds 1 Timeout, in seconds, for calculating hostname.
spring.cloud.inetutils.use-only-site-local-interfaces false Whether to use only interfaces with site local addresses. See {@link InetAddress#isSiteLocalAddress()} for more details.
spring.cloud.loadbalancer.cache.caffeine.spec The spec to use to create caches. See CaffeineSpec for more details on the spec format.
spring.cloud.loadbalancer.cache.capacity 256 Initial cache capacity expressed as int.
spring.cloud.loadbalancer.cache.enabled true Enables Spring Cloud LoadBalancer caching mechanism.
spring.cloud.loadbalancer.cache.ttl 35s Time To Live - time counted from writing of the record, after which cache entries are expired, expressed as a {@link Duration}. The property {@link String} has to be in keeping with the appropriate syntax as specified in Spring Boot StringToDurationConverter. @see StringToDurationConverter.java
spring.cloud.loadbalancer.clients 
spring.cloud.loadbalancer.configurations default Enables a predefined LoadBalancer configuration.
spring.cloud.loadbalancer.enabled true Enables Spring Cloud LoadBalancer.
spring.cloud.loadbalancer.health-check Properties for HealthCheckServiceInstanceListSupplier.
spring.cloud.loadbalancer.hint Allows setting the value of hint that is passed on to the LoadBalancer request and can subsequently be used in {@link ReactiveLoadBalancer} implementations.
spring.cloud.loadbalancer.hint-header-name X-SC-LB-Hint Allows setting the name of the header used for passing the hint for hint-based service instance filtering.
spring.cloud.loadbalancer.retry Properties for Spring-Retry and Reactor Retry support in Spring Cloud LoadBalancer.
spring.cloud.loadbalancer.retry.avoid-previous-instance true Enables wrapping ServiceInstanceListSupplier beans with RetryAwareServiceInstanceListSupplier if Spring-Retry is in the classpath.

spring.cloud.loadbalancer.sticky-session Properties for LoadBalancer sticky-session.
spring.cloud.loadbalancer.x-forwarded Enabling X-Forwarded Host and Proto Headers.
spring.cloud.loadbalancer.zone Spring Cloud LoadBalancer zone.
spring.cloud.refresh.additional-property-sources-to-retain Additional property sources to retain during a refresh. Typically only system property sources are retained. This property allows property sources, such as property sources created by EnvironmentPostProcessors to be retained as well.
spring.cloud.refresh.enabled true Enables autoconfiguration for the refresh scope and associated features.
spring.cloud.refresh.extra-refreshable true Additional class names for beans to post process into refresh scope.
spring.cloud.refresh.never-refreshable true Comma separated list of class names for beans to never be refreshed or rebound.
spring.cloud.service-registry.auto-registration.enabled true Whether service auto-registration is enabled. Defaults to true.
spring.cloud.service-registry.auto-registration.fail-fast false Whether startup fails if there is no AutoServiceRegistration. Defaults to false.
spring.cloud.service-registry.auto-registration.register-management true Whether to register the management as a service. Defaults to true.
