##调用方法

public static final Option<String> HA_ZOOKEEPER_QUORUM =
    key("high-availability.zookeeper.quorum")
        .noDefaultValue()
        .withDeprecatedKeys("recovery.zookeeper.quorum")
        .withDescription("The ZooKeeper quorum to use, when running Flink in a high-availability mode with ZooKeeper.");

Configuration configuration = new Configuration();
//设置监听,当有变化的时候进行通知
configuration.addChangeListener((x, y, z) -> {
    System.out.println(x + "," + y + "," + z);
});

//正常获取(字符串方式)
configuration.setValue("testKey", "testValue");
String s = configuration.getValue(testKey);
    
//正常获取
configuration.setValue(HA_ZOOKEEPER_QUORUM, "127.0.0.1:2181");
String s = configuration.getValue(HA_ZOOKEEPER_QUORUM);

//过期key匹配获取
configuration.setValue("recovery.zookeeper.quorum", "127.0.0.1:2181");
String s = configuration.getValue(HA_ZOOKEEPER_QUORUM);
