一、ribbon(service-ribbon)
新建一个spring cloud项目
在启动类加上@EnableDiscoveryClient注解,向服务中心注册
@EnableDiscoveryClient
@SpringBootApplication
public class ServiceRibbonApplication {
public static void main(String[] args) {
SpringApplication.run(ServiceRibbonApplication.class, args);
}
@Bean
@LoadBalanced
RestTemplate restTemplate() {
return new RestTemplate();
}
}
application.yml配置
eureka:
client:
serviceUrl:
defaultZone: http://localhost:8761/eureka/
server:
port: 8764
spring:
application:
name: service-ribbon
测试service:
@Service
public class HelloService {
@Autowired
RestTemplate restTemplate;
public String hiService(String name) {
return restTemplate.getForObject("http://EUREKA-SERVER/hi?name="+name,String.class);
}
}
测试controller:
@RestController
public class HelloControler {
@Autowired
HelloService helloService;
@GetMapping(value = "/hi")
public String hi(@RequestParam String name) {
return helloService.hiService( name );
}
}
启动http://localhost:8764/hi?name=forezp
二、Feign(service-feign)
新建一个spring cloud项目,加入feign依赖
启动类:加上@EnableFeignClients注解开启Feign的功能
@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients
public class ServiceFeignApplication {
public static void main(String[] args) {
SpringApplication.run(ServiceFeignApplication.class, args);
}
}
application.yml
eureka:
client:
serviceUrl:
defaultZone: http://localhost:8761/eureka/
server:
port: 8765
spring:
application:
name: service-feign
测试service:
@FeignClient(value = "eureka-server")
public interface SchedualServiceHi {
@RequestMapping(value = "/hi",method = RequestMethod.GET)
String sayHiFromClientOne(@RequestParam(value = "name") String name);
}
测试controller:
@RestController
public class HiController {
@Autowired
SchedualServiceHi schedualServiceHi;
@RequestMapping(value = "/hi",method = RequestMethod.GET)
public String sayHi(@RequestParam String name){
return schedualServiceHi.sayHiFromClientOne(name);
}
}
