第一步：导入依赖
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>第一步：进行配置
server:
port: 80
eureka:
client:
register-with-eureka: false
service-url:
defaultZone: http://eureka7001.com:7001/eureka/,http://eureka7002.com:7002/eureka/第三步：开启注解
@SpringBootApplication
@EnableFeignClients
public class OrderFeignMain80 {
public static void main(String[] args) {
SpringApplication.run(OrderFeignMain80.class,args);
}
}第四步：对接口进行注解
@Component
@FeignClient(value = "CLOUD-PAYMENT-SERVICE")
public interface PaymentService {
@GetMapping(value = "payment/get/{id}")
CommonResult<Payment> getPaymentById(@PathVariable(value = "id") Long id);
@GetMapping(value = "payment/timeout")
String getPaymentTimeout();
}第五步：调用接口
@RestController
public class PaymentController {
@Resource
private PaymentService paymentService;
@GetMapping(value = "consumer/payment/get/{id}")
public CommonResult<Payment> getPaymentById(@PathVariable("id") Long id) {
return paymentService.getPaymentById(id);
}
@GetMapping(value = "consumer/payment/timeout")
public String getPaymentTimeout(){
return paymentService.getPaymentTimeout();
}
}feign日志增强
#日志增强
logging:
level:
com.atguigu.springcloud.service.PaymentService: debug日志增强配置类
@Configuration
public class FeignConfig {
@Bean
Logger.Level feignLevelInfo(){
return Logger.Level.FULL; //full表示一个详细日志
}
}feign 超时等待配置 设置指定的时间，等待返回结果，超时报错，默认是1s
ribbon:
# 值得是建立连接所用的时间，适用于网络状态正常的情况下，两端连接所用的时间
ReadTimeout: 5000
# 指的是建立连接后从服务端读取到可用资源所用的时间
ConnectTimeout: 5000
