1. pom.xml中加入
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-hystrix</artifactId> </dependency>
2. application.properties裏面加入eureka配置
eureka.client.serviceUrl.defaultZone=http://host:port/eureka/
2. Application.java加入註解
@EnableCircuitBreaker，@EnableEurekaClient， @EnableDiscoveryClient
@EnableCircuitBreaker
@EnableDiscoveryClient
@EnableEurekaClient
public class SmartHomeAuthServiceMain {
}3. 具體接口前加入回滾方法
@HystrixCommand(fallbackMethod = "findOrderFallback", commandProperties = {
@HystrixProperty(name = "execution.isolation.thread.timeoutInMilliseconds", value = "2000")
})
public String authPublishMessage(@RequestBody InnerAuthPublishMessageModel requestParas) {
}
public String findOrderFallback(InnerAuthPublishMessageModel requestParas) {
return "failed"
}回滾方法findOrderFallback參數和返回值和之前的一樣
4. github配置文檔
