当你配置好你的SpringCloudEureka并加上安全验证时，你发现你客户端连接不上你的服务器时候 ，这时候你就要考虑是不是下面两个问题导致你出现这个错误。
1、Spring Cloud Eureka 客户端配置你的服务注册中心时候 没有加上你服务端安全检查的用户名和密码
spring: application: name: spring-cloud-eureka-client #由于我们前面的eureka的服务端加入spring securit的验证配置 所以这里我们需要加上这个配置信息来能够访问 security: user: name: root password: root server: port: 8761 eureka: client: service-url: #配置eureka服务注册中心地址 如果eureka server服务注册中心是集群部署 只配置一个其他服务注册中心也能发现 defaultZone: http://${spring.security.user.name}:${spring.security.user.password}@eureka1:8861/eureka/
2、未将SpringCloudEureka 中配置的SpringSecurity 的csrf配置信息禁止
@Configuration @EnableWebSecurity public class WebSecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http.csrf().disable(); super.configure(http); } }
