spring boot版本 2.0 spring cloud版本 Finchley.M9

错误信息如下：

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

解决方案：eureka server端 application.yml

server:
  port: 9003
spring:
  security:
    user:
      name: admin
      password: admin
eureka:
  instance:
    hostname: localhost #服务注册中心IP地址
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: http://${spring.security.user.name}:${spring.security.user.password}@${eureka.instance.hostname}:${server.port}/eureka/

eureka client端 application.yml

server:
  port: 9000
spring:
  application:
    name: userApplication
eureka:
  client:
    service-url:
      defaultZone: http://admin:admin@localhost:9003/eureka/

关闭了这两个

register-with-eureka: false
fetch-registry: false

新建一个WebSecurityConfig.java,关闭SpringSecurity的CSRF保护

@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable();
        super.configure(http);
    }
}
