springCloud学习笔记(七)——向consul中注册服务，并实现调用

一、下载部署consul

1. docker部署consul2.官网下载 二、SpringCloud向consul中注册服务

1.引入库2.完整pom文件内容3.yml相关配置4.使用@EnableDiscoveryClient注解声明main方法5.RestTemplate配置6.测试方法1.运行截图 总结

部署命令

docker run -d --name consul -p 8500:8500 consul

查看是否部署成功，查询consul版本

docker exec -it consul consul -version

    private static final String INVOKE_URL = "http://consul-consumer2021";



    
    @GetMapping(value = "getMessage")
    public String getMessage() {
        return restTemplate.getForObject(INVOKE_URL + "/consulConsumerController/sendMessage", String.class);

}

运行项目查询consul的UI界面
consul-servant2020服务调用consul-consumer2021中方法

引入jar包配置consul服务调用方法
