补充下，这个ip是可以变化的，不是写到配置文件里的，
类似于restTemplate.getForEntity("http://xxx.xxx.xxx.xxx:8081/SomeServiceImpl/sayHello?name=tom", String.class);

provider 发布完之后, 本来就可以直接这样调用. 本来就支持的.
但是有一个细节需要注意下, 调用 url 是 111.111.111.111:8080 这样的，走Spring的RestTemplate原生的逻辑，就是没有经过我们的handler链之类的了，不具备consumer端治理能力和Java-Chassis的扩展功能. url是 cse://serviceName/xxx 这样的，走的是Java-Chassis的逻辑发请求的，会经过我们的handler链之类的，有我们的consumer端治理能力

之前用的dubbo，提供ReferenceConfig类支持直连ip，实现和这个类似，https://blog.csdn.net/BuquTianya/article/details/69229384

Provider:
```java
@RequestMapping(path = "/sayhi", method = RequestMethod.POST, produces = "text/plain")
public String sayHi(@RequestParam(name = "name", defaultValue = "test") String name) {
return "Hello " + name;

抱歉, 有个地方会错意了..
```java
// 这种方式可以通过设置配置, 偏好走 highway 或者rest.
String sayHiResult =
restTemplate.postForObject("cse://springmvc/springmvchello/sayhi?name=Java Chassis", null, String.class);
// 这种方式走的 RestTemplate原生的逻辑, 无法走 highway
String sayHiResult2 =
restTemplate.postForObject("http://ip:8080/springmvchello/sayhi?name=Java Chassis", null, String.class);
```

抱歉，问题可能没有描述清楚，你给的demo，我之前是测过类似的，不过我理解这是rest通信模式，基于http的，不是highway，我想问的是highway通道，如highway://localhost:8080/springmvchello/sayhi?name=Java Chassis，看你的第一条回答，ip+端口是只支持rest吗?
dubbo的相关实现代码，图片上传不了，看下这个链接https://blog.csdn.net/BuquTianya/article/details/69229384

后面类似问题, 建议自己先写一个demo, 自己测一下

SpringMVC JAX-RS RPC 这些只是服务端编程模型，说白了只是你写代码的形式.
highway 这些是传输模型. 两个模型本来就是解耦的.
我给你的示例 是 SpringMVC 编程模型. 至于用不用 highway 是自己的配置.
建议 先了解一下 基本的知识.

提issue前，网上有的资料基本是都看了下的，有些地方确实不太理解，经过本地测试，再确认一个问题
1、只提供rest通信
```
microservice.yaml
rest:
address: 0.0.0.0:8080 # 服务REST端口
```
2、只提供highway通信，不支持restTemplate.postForObject("http://ip:port/method?name=Java", null, String.class)访问形式;
```
microservice.yaml
highway:
address: 0.0.0.0:8080 # 服务highway端口
```
3、两种通信方式都提供
```
microservice.yaml
highway:
address: 0.0.0.0:8080 # 服务highway端口
rest:
address: 0.0.0.0:8081 # 服务REST端口
```
