Spring Cloud Eureka uses the client when registering after adding Spring Security permission verification

Eureka.client.service-url.defaultZone= http://xiaoming:10010@localhost:8761/eureka/

The client reported an error when registering

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: 1.8.0mm 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.

It is found that csrf (cross-site request forgery) check is enabled by default in the version after spring boot 2.x, which leads to an error report.

Solution: add a configuration class to the eureka service project, ignoring the check for / eureka requests

@ EnableWebSecuritypublic class WebSecurityConfig extends WebSecurityConfigurerAdapter {@ Override protected void configure (HttpSecurity http) throws Exception {http.csrf (). IgnoringAntMatchers ("/ eureka/**"); super.configure (http);}} the above content is how to solve the problem that the client cannot register after adding Spring Security permission verification.
