[Java知识库]【原创&转载】SpringCloud之坑：Eureka Client注册报错 Cannot execute request on any known server解决方案

注意

————————————————————————————————————————————

WebSecurityConfig需要添加 @EnableWebSecurity 注解

添加Security权限验证后注册中心地址需添加用户名及密码**

客户端及服务端注解

服务方配置代码

server:
  port: 7001

eureka:
  instance:
    hostname: localhost             #Eureka服务端的实例名称
  client:
    register-with-eureka: false     #false表示不向注册中心注册自己
    fetch-registry: false           #false表示自己就是注册中心，职责就是维护服务实例，并不需要去检索服务
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

spring:
  security:
    user:
      name: admin
      password: 123456

同时服务方需要关闭Security的CSRF配置，写配置类以关闭CSRF：

@EnableWebSecurity
class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().ignoringAntMatchers("/eureka/**");
        super.configure(http);
    }
}

客户端

eureka:
  client:
    service-url:
      defaultZone: http://admin:123456@localhost:7001/eureka/
