eureka服务端添加security验证之后，client注册失败

问题：erueka服务端添加security验证之后，client注册失败：

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

解决：

在eureke服务端添加配置：

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // Configure HttpSecurity as needed (e.g. enable http basic).
        http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.NEVER);
        http.csrf().disable();
        //注意：为了可以使用 http://${user}:${password}@${host}:${port}/eureka/ 这种方式登录,所以必须是httpBasic,
        // 如果是form方式,不能使用url格式登录
        http.authorizeRequests().anyRequest().authenticated().and().httpBasic();

    }
}

spring boot 使用 Security：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>
