consul 项目

1.下载安装consul

下载地址: https://www.consul.io/downloads 解压安装...

附:https://blog.youkuaiyun.com/a312586670/article/details/105337943 一篇比较好的博客(个人感觉)

2.我用的是dev参数启动的:

附脚本:  ./consul agent -dev      # ( start.sh )

3.建项目

public class ConsulController {

    @Value("${server.port}")
    private String servicePort;

    @RequestMapping(value = "/payment/consul")
    public String payment(){
        //http://localhost:8006/payment/consul
        return servicePort + UUID.randomUUID().toString();
    }
}

public class Application8081 {

    public static void main(String[] args) {
        SpringApplication.run(Application8081.class, args);
