通过配置文件和 @Conditional 方式自动切换

@Conditional(value = { RedisContextHolder.RedisServiceCondition.class })
private RedisClient redisClient;

@Conditional(value = { RedisClusterContextHolder.RedisClusterServiceCondition.class })
private RedisClusterClient redisClient;



public static class RedisServiceCondition {
@Override
public boolean matches(ConditionContext context, AnnotatedTypeMetadata metadata) {
context.getEnvironment().getProperty("application.redis")
....
return boolean;
}
}
