我使用的是Java Couchbase客户端版本1.4.6

我们有几个节点用于HA .

问题是，如果一个节点发生故障，客户端不会尝试下一个节点，只需继续尝试连接的第一个节点（在它关闭之前）

知道如何设置客户端跳转到群集中的下一个couchbase节点吗？

这是我配置它的方式：

private CouchbaseClient client;


private ArrayList<URI> nodes = new ArrayList<>();
    private String uri;
    private String bucket;
    private String password;

    @Override
    public void init() {
        uri = "host.1,host.2,host.3"
        bucket = "default"
        password = "password"
        try {
            addUrlList();
            client = new CouchbaseClient(nodes, bucket, password);
        } catch (Exception e) {
            logger.error("Error connecting to Couchbase: " + e.getMessage(), e);
        }
    }

    private void addUrlList() {
        List<String> urlList= Arrays.asList(uri.split(","));
        for(String url:urlList)
        {
            uri = "http://" + url + ":8091/pools";
            nodes.add(URI.create(uri));
        }
    }

这就是例外：
