Service fails to connect to registry solution when authentication is turned on

The main modules provided by the SpringCloud component include: service discovery (Eureka), circuit breaker (Hystrix), smart road (Zuul), client load balancing (Ribbon), Archaius, Turbine, etc.

Eureka is equivalent to zookeeper, which is used for service registration and discovery in microservice projects. When using springBoot+springCloud to develop microservices, the basic purpose can be achieved through some simple configurations

Registry access rights configuration

Add dependencies in registry service pom.xml

org.springframework.boot spring-boot-starter-security ">

 <!-- Add registry permission dependency -->





In the registry service application.properties file (note), the content is as follows

#New version open permission#Registry center configuration spring.application.name=szq-serverserver.port=8761eureka.instance.hostname=localhosteureka.client.registerWithEureka=falseeureka.client.fetch-registry=falseeureka.client.serviceUrl.defaultZone=http ://admin:123456@${eureka.instance.hostname}:${server.port}/eureka/#The new version enables permissions spring.security.user.name=adminspring.security.user.password=123456

Start the registry service project, enter http://localhost:8761/ in the browser and the eureka console page will appear and ask for the user name and password box to be successful

The service cannot connect to the registry solution after the verification is turned on

run error message

com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server

The security of Spring Cloud 2.0 and above has csrf verification enabled by default. To configure the csrf verification of security on the eurekaServer side, it is false.

When registering in the service registry, add the account password eureka.client.serviceUrl.defaultZone=http://admin:123456@localhost:8761/eureka/

Add a class that inherits WebSecurityConfigurerAdapter

Add the @EnableWebSecurity annotation to the class;

Override the configure(HttpSecurity http) method of the parent class and turn off csrf

package com.pflm;import org.springframework.security.config.annotation.web.builders.HttpSecurity;import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;import org.springframework.security.config.annotation. web.configuration.WebSecurityConfigurerAdapter;/**
