Access Control Lists (ACLs)
You can add authentication information for Zookeeper ACLs by calling the addAuthInfo
method of a CuratorFramework
bean. One way to accomplish this is to provide your own
CuratorFramework
bean, as shown in the following example:
@BoostrapConfiguration
public class CustomCuratorFrameworkConfig {
@Bean
public CuratorFramework curatorFramework() {
CuratorFramework curator = new CuratorFramework();
curator.addAuthInfo("digest", "user:password".getBytes());
return curator;
}
}
Consult
the ZookeeperAutoConfiguration class
to see how the CuratorFramework
bean’s default configuration.
Alternatively, you can add your credentials from a class that depends on the existing
CuratorFramework
bean, as shown in the following example:
@BoostrapConfiguration
public class DefaultCuratorFrameworkConfig {
public ZookeeperConfig(CuratorFramework curator) {
curator.addAuthInfo("digest", "user:password".getBytes());
}
}
The creation of this bean must occur during the boostrapping phase. You can register
configuration classes to run during this phase by annotating them with
@BootstrapConfiguration
and including them in a comma-separated list that you set as the
value of the org.springframework.cloud.bootstrap.BootstrapConfiguration
property in the
resources/META-INF/spring.factories
file, as shown in the following example:
org.springframework.cloud.bootstrap.BootstrapConfiguration=\ my.project.CustomCuratorFrameworkConfig,\ my.project.DefaultCuratorFrameworkConfig
