本教程详细介绍如何使用Alibaba Cloud SDK for Java创建和删除SLB实例。

前提条件

在使用本教程前,请确保已完成以下操作:

  • 使用Alibaba Cloud SDK for Java,您需要一个阿里云账号和访问密钥(AccessKey)。 请在阿里云控制台中的AccessKey管理页面上创建和查看您的AccessKey。
  • 确保您已经安装了Alibaba Cloud SDK for Java,准确的SDK版本号,请参见阿里云开发工具包(SDK)

运行结果

正确的运行结果类似如下:

-------------------------------createLoadBalancer------------------------------- {     "requestId": "A10A122E-5527-4642-A20B-12D6F8BB1D3D",      "loadBalancerId": "lb-8vbmp1b3xxxxxxxxkp9l0",      "resourceGroupId": "rg-acfxxxxxxxx6aiy",      "address": "39.xx.xx.164",      "loadBalancerName": "SLB1",      "vpcId": "",      "vSwitchId": "",      "networkType": "classic",      "addressIPVersion": "ipv4" } -------------------------------deleteLoadBalancer------------------------------- {     "requestId": "B78D96B9-0685-4CC7-9CF2-00A793ACC1B2" }
