通过 Spring Cloud 原生注解 @EnableDiscoveryClient 开启服务注册发现功能
@SpringBootApplication @EnableDiscoveryClient public class NacosProviderApplication { public static void main(String[] args) { SpringApplication.run(NacosProviderApplication.class, args); } @RestController class EchoController { @RequestMapping(value = "/echo/{string}", method = RequestMethod.GET) public String echo(@PathVariable String string) { return "Hello Nacos Discovery " + string; } } }
@EnableDiscoveryClient 开启服务注册发现功能给 RestTemplate 实例添加 @LoadBalanced 注解，开启 @LoadBalanced 与 Ribbon 的集成：
@SpringBootApplication @EnableDiscoveryClient public class NacosConsumerApplication { @LoadBalanced @Bean public RestTemplate restTemplate() { return new RestTemplate(); } public static void main(String[] args) { SpringApplication.run(NacosConsumerApplication.class, args); } @RestController public class TestController { private final RestTemplate restTemplate; @Autowired public TestController(RestTemplate restTemplate) {this.restTemplate = restTemplate;} @RequestMapping(value = "/echo/{str}", method = RequestMethod.GET) public String echo(@PathVariable String str) { return restTemplate.getForObject("http://service-provider/echo/" + str, String.class); } } }
