继续上一篇，接下来Springcloud配置Netflix-Ribbon集成Hystrix断路器的功能。
1、添加依赖
<!--使用hystrix，测试断路器-->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
</dependency>
2、启动类
@EnableHystrix
3、controller层
修改之前的controller层，添加hystrix特有的fallbackMethod进行断路器
@RequestMapping(value = "/ribbon")
@RestController
public class LoadBalanceController {
private Logger logger = LoggerFactory.getLogger(LoadBalanceController.class);
@Autowired
RestTemplate restTemplate;
@GetMapping(value = "/toLoadBalance")
@HystrixCommand(fallbackMethod = "ribbonHystrixError")
public void toLoadBalance(){
for (int i = 0; i < 10; i++){
String str = restTemplate.getForObject("http://eureka-client/testRabbion",String.class);
logger.info(str);
}
}
public void ribbonHystrixError(){
logger.info("ribbon error");
}
}
4、启动测试
启动eureka-server，netflix-ribbon，调用接口
http://localhost:8075/ribbon/toLoadBalance
测试成功
