45. Hystrix熔断器加入

1. pom.xml中加入

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-hystrix</artifactId>
</dependency>

2. Application.java加入注解

@EnableCircuitBreaker，@EnableEurekaClient， @EnableDiscoveryClient

@EnableCircuitBreaker
@EnableDiscoveryClient
@EnableEurekaClient
public class SmartHomeAuthServiceMain {

}

3. 具体接口前加入回滚方法

@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"
}
