怎么在springboot 启动时把redis集群的 host:port password 打印出来

你可以在Spring Boot启动的时候注册一个ApplicationListener来监听ApplicationStartedEvent事件,然后在事件回调方法中获取Redis集群的host、port和password,并将其打印出来。下面是一个示例:
```java
@Component
public class RedisClusterInfoPrinter implements ApplicationListener<ApplicationStartedEvent> {
@Autowired
private RedisConnectionFactory redisConnectionFactory;
@Override
public void onApplicationEvent(ApplicationStartedEvent event) {
RedisClusterConfiguration clusterConfiguration = (RedisClusterConfiguration) redisConnectionFactory.getClusterConfiguration();
List<RedisNode> nodes = clusterConfiguration.getClusterNodes();
String password = clusterConfiguration.getPassword() == null ? "" : new String(clusterConfiguration.getPassword());
for (RedisNode node : nodes) {
System.out.println("Redis cluster node: " + node.getHost() + ":" + node.getPort() + ", password: " + password);
}
}
}
```
在这个示例中,我们定义了一个名为RedisClusterInfoPrinter的Spring组件,并实现了ApplicationListener接口。在onApplicationEvent方法中,我们首先通过@Autowired注解注入了RedisConnectionFactory,然后通过它获取了Redis集群的配置信息。最后,我们遍历了所有的集群节点,将它们的host、port和password打印出来。注意,在打印password时,我们需要将其转换为字符串形式。
