Question

我已经在centos服务器上安装了Couchbase，现在尝试使用Java SDK访问它，但它会抛出非法状态异常。我可以从8091端口的浏览器访问Couchbase控制台。是否还有其他步骤可以通过Java SDK访问它？我也可以通过浏览器访问Couchbase Web控制台。

以下是我用过的代码：

公共类CacheInitialize {

public static CouchbaseClient client = null;

public void Initialize() {
    final ArrayList<URI> nodes = new ArrayList<URI>();

    // Add one or more nodes of your cluster (exchange the IP with yours)
    nodes.add(URI.create("http://IP-ADDRESS/pools"));

    try {
        client = new CouchbaseClient(nodes, "default", "");
    } catch (final Exception e) {
        System.err.println("Error connecting to Couchbase: "
                + e.getMessage());
        System.exit(1);
    }
}

public static void main(final String[] args) {
    new CacheInitialize().Initialize();
    final CouchbaseClient client = CacheInitialize.client;
    // Store a Document
    client.set("my-first-document", "Hello Couchbase!");

    // Retreive the Document and print it
    System.out.println(client.get("my-first-document"));

    // Shutting down properly
    client.shutdown();
}

}

这是我得到的例外：

Couchbase在远程linux机器上
