配置

eureka 默认配置类 DefaultEurekaServerConfig

// 配置的驱逐时间
serverConfig.getEvictionIntervalTimerInMs();
// 获取续订百分比阈值
int registrySizeThreshold = (int) (registrySize * serverConfig.getRenewalPercentThreshold());

默认开启自我保护，是不会定时剔除实例的

    @Override
    public boolean isLeaseExpirationEnabled() {
        if (!isSelfPreservationModeEnabled()) {
            // The self preservation mode is disabled, hence allowing the instances to expire.
            return true;
        }
        return numberOfRenewsPerMinThreshold > 0 && getNumOfRenewsInLastMin() > numberOfRenewsPerMinThreshold;
    }

默认情况下，EurekaClient 使用 Jersey 进行 HTTP 通信。如果希望避免来自 Jersey 的依赖关系，可以将其从依赖关系中排除。Spring Cloud 基于 Spring 自动配置传输客户端RestTemplate。以下示例显示排除了 Jersey：

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
    <exclusions>
        <exclusion>
            <groupId>com.sun.jersey</groupId>
            <artifactId>jersey-client</artifactId>
        </exclusion>
        <exclusion>
            <groupId>com.sun.jersey</groupId>
            <artifactId>jersey-core</artifactId>
        </exclusion>
        <exclusion>
            <groupId>com.sun.jersey.contribs</groupId>
            <artifactId>jersey-apache-client4</artifactId>
        </exclusion>
    </exclusions>
