This article shows you an example analysis of the nacos registry, which is concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.
First, create a new project.
Service provider
Create a new springboot project
I use maven to build the project, relying on the following
Org.springframework.boot spring-boot-starter org.springframework.boot spring-boot-starter-test test org.springframework.boot spring-boot-starter-web org.springframework.cloud spring-cloud-starter-alibaba-nacos-discovery
The required jar package has been downloaded
The previous article on changing configuration introduced the download and installation of nacos. Now let's take a look at the nacos registry.
First, create a new project.
Service provider creates a new springboot project
I use maven to build the project, relying on the following
The required jar package has been downloaded
Paste the configuration. I use the configuration in yaml format. It looks really clear.
Server: port: 8881spring: application: name: nacos-provider cloud: nacos: discovery: server-addr: 127.0.0.1:8848
Finally, let's do a little test class.
@ SpringBootApplication@EnableDiscoveryClient@RestController@Slf4jpublic class NacosProviderApplication {@ GetMapping ("/ hello") public String hello (@ RequestParam String name) {log.info ("invoked name =" + name); return "hello" + name;} public static void main (String [] args) {SpringApplication.run (NacosProviderApplication.class, args);}}
Come down and let's start the service.
See the log. Our service has been registered with nacos. Open nacos to have a look.
Haha, our service has successfully registered with nacos.
Service consumers
Let's create a consumer.
Maven dependencies are all the same, so change the configuration slightly.
Server: port: 8882spring: application: name: nacos-consumer cloud: nacos: discovery: server-addr: 127.0.0.1:8848
Startup class
@ SpringBootApplication@EnableDiscoveryClient@Slf4j@RestControllerpublic class NacosConsumerApplication {@ Autowired private RestTemplate restTemplate; @ GetMapping ("/ callNacos") public String testRest (@ RequestParam ("name") String name) {String result = restTemplate.getForEntity ("http://nacos-provider/hello?name="+name,String.class).getBody(); log.info (" calling provider returns: {} ", result); return result } public static void main (String [] args) {SpringApplication.run (NacosConsumerApplication.class, args);}}
Found an error report after startup
It turns out that RestTemplate is registered with the spring container.
@ Configurationpublic class RestTemplateConfig {@ LoadBalanced @ Bean public RestTemplate resultTemplate () {RestTemplate template = new RestTemplate (); return template;}}
After registration, we start to have a look, this time there is no exception.
