Spring Cloud Eureka 在添加了 Spring Security 权限验证之后，客户端注册的时候使用
eureka.client.service-url.defaultZone=http://xiaoming:10010@localhost:8761/eureka/
客户端注册时候报错
com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server at com.netflix.discovery.shared.transport.decorator.RetryableEurekaHttpClient.execute(RetryableEurekaHttpClient.java:112) ~[eureka-client-1.9.12.jar:1.9.12] at com.netflix.discovery.shared.transport.decorator.EurekaHttpClientDecorator.register(EurekaHttpClientDecorator.java:56) ~[eureka-client-1.9.12.jar:1.9.12] at com.netflix.discovery.shared.transport.decorator.EurekaHttpClientDecorator$1.execute(EurekaHttpClientDecorator.java:59) ~[eureka-client-1.9.12.jar:1.9.12] at com.netflix.discovery.shared.transport.decorator.SessionedEurekaHttpClient.execute(SessionedEurekaHttpClient.java:77) ~[eureka-client-1.9.12.jar:1.9.12] at com.netflix.discovery.shared.transport.decorator.EurekaHttpClientDecorator.register(EurekaHttpClientDecorator.java:56) ~[eureka-client-1.9.12.jar:1.9.12] at com.netflix.discovery.DiscoveryClient.register(DiscoveryClient.java:847) ~[eureka-client-1.9.12.jar:1.9.12] at com.netflix.discovery.InstanceInfoReplicator.run(InstanceInfoReplicator.java:121) ~[eureka-client-1.9.12.jar:1.9.12] at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) [na:1.8.0_172] at java.util.concurrent.FutureTask.run(FutureTask.java:266) [na:1.8.0_172] at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$201(ScheduledThreadPoolExecutor.java:180) [na:1.8.0_172] at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:293) [na:1.8.0_172] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) [na:1.8.0_172] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) [na:1.8.0_172] at java.lang.Thread.run(Thread.java:748) [na:1.8.0_172]
经查发现是 spring boot 2.x 之后的版本默认开启了 csrf （跨站请求伪造）检查，所以导致报错
解决方式：在eureka服务项目中添加一个配置类，忽略对 /eureka 请求的检查
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().ignoringAntMatchers("/eureka/**");
super.configure(http);
}
