eureka-service配置
application.yml
#eureka默認情況下,將自己作為客服端進行注冊,因此需要禁用該行為
registerWithEureka: false? #表示是否將自己注冊到Eureka Server上，默認為true
fetchRegistry: false? #表示是否從Eureka Server上獲取注冊信息，默認為true
pom.xml
在pom文件中，重點注意如下依賴：
1.
<parent>
? ? ? ? <groupId>org.springframework.boot</groupId>
? ? ? ? <artifactId>spring-boot-starter-parent</artifactId>
? ? ? ? <version>2.0.2.RELEASE</version>
? ? ? ? <relativePath />
</parent>
若無此依賴，啟動時報錯：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'gsonBuilder' defined in class path resource [org/springframework/boot/autoconfigure/gson/GsonAutoConfiguration.class]:Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.google.gson.GsonBuilder]: Factory method 'gsonBuilder' threw exception; nested exception is java.lang.BootstrapMethodError: java.lang.NoSuchMethodError: com.google.gson.GsonBuilder.setLenient()Lcom/google/gson/GsonBuilder;

若無此處依賴，啟動該spring-cloud-starter-netflix-eureka-server會報錯：
java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Tomcat].StandardHost[localhost]]

該依賴用于配置eureka服務(wù)端。
