Client创建_Java SDK_用户指南_图计算服务-阿里云

引用SDK后，初始化Client示例如下。

注意： 实例域名(instanceDomain)，端口(instanceDomainPort)以及AK信息(accessKey, accessSecret)需要SDK用户自行提供。

String instanceDomain = "*****";
int instanceDomainPort = **;
String accessKey = "***";
String accessSecret = "***";
CredentialsManager credentialsManager = new CredentialsManager(accessKey, accessSecret);
GryoMapper.Builder kryo = GryoMapper.build().addRegistry(MaxGraphIORegistry.getInstance());
MessageSerializer serializer = new GryoMessageSerializerV1d0(kryo);
try {
    cluster = Cluster.build()
            .addContactPoint(instanceDomain)
            .port(instanceDomainPort)
            .serializer(serializer)
            .credentials(credentialsManager.getUserName(), credentialsManager.getPassword())
            .create();
} catch (Exception e) {
    throw new IllegalArgumentException("build credentials password fail", e);
}
client = cluster.connect();

instanceDomain和instancePort可以在DataWorks控制台的GraphCompute实例详情页面找到，图示如下： client001
