    //这里配置的配置可以改成 jdbc redis 等其他方式
    @Bean

// security配置主要是userDetailsService 

@Configuration

@SpringBootApplication

  sessions: stateless
  oauth2:

      loadBalanced: true 
      user-info-uri: http://gateway-server/uaa/user

//curl 不会用的可以参考文章总结里面 Rest Client 那个报文工具。
// 这里的账户是在 auth-server里面写死的，service实现里面。
 curl -H "Authorization:Basic YnJvd3Nlcjo=" -d "grant_type=password&scope=ui&username=123&password=456" localhost:6666/uaa/oauth/token

curl -H "Authorization:Bearer c8df8942-f032-4403-92fc-f23019819da9" localhost:6666/demo/getResource

SUCCESS，授权成功拿到资源啦.当前用户：123

      loadBalanced: true  #设置这个才可以使用eureka的服务名，配合loadBalancerInterceptor bean。
