spring整合hystrix

引入依赖

<!--hystrix核心代码--> <dependency> <groupId>com.netflix.hystrix</groupId> <artifactId>hystrix-core</artifactId> <version>1.4.22</version> </dependency> <dependency> <groupId>com.netflix.hystrix</groupId> <artifactId>hystrix-metrics-event-stream</artifactId> <version>1.4.22</version> </dependency> <!--切面注解的方式--> <dependency> <groupId>com.netflix.hystrix</groupId> <artifactId>hystrix-javanica</artifactId> <version>1.4.22</version> </dependency>

spring配置切面

<aop:aspectj-autoproxy proxy-target-class="true" /> <bean id="hystrixAspect" class="com.netflix.hystrix.contrib.javanica.aop.aspectj.HystrixCommandAspect"></bean>

插入注解

@HystrixCommand(groupKey="UserGroup", commandKey = "GetUserByIdCommand", fallbackMethod = "fallback", //ignoreExceptions = {BadRequestException.class} 指定哪一类异常可以忽略,不走fallback commandProperties = { @HystrixProperty(name = "execution.isolation.thread.timeoutInMilliseconds", value = "50000"),//方法执行超时时间 @HystrixProperty(name = "circuitBreaker.requestVolumeThreshold", value = "10"),//当并发错误个数达到此阀值时(在时间窗口内)，触发隔断器 @HystrixProperty(name = "metrics.rollingStats.timeInMilliseconds", value = "60000"),//滚动窗口时间长度 @HystrixProperty(name = "metrics.rollingStats.numBuckets", value = "12"),//滚动窗口的桶数 @HystrixProperty(name = "circuitBreaker.sleepWindowInMilliseconds", value = "60000"),//隔断器被触发后，睡眠多长时间开始重试请求 }, threadPoolProperties = { @HystrixProperty(name = "coreSize", value = "20"), @HystrixProperty(name = "maxQueueSize", value = "100"), } ) @Override public String hystrix(String loanNumber) { System.out.println(loanNumber + "YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYHystrix!" + Thread.currentThread().getName()); // if(1/0 == 0){ // } try { Thread.sleep(500); } catch (InterruptedException e) { // logger.doError(e.getMessage()); } return null; } public String fallback(String loanNumber,Throwable e){ // logger.doError("",e.getMessage()); System.out.println("XXXXXXXXXXXXXXXXXXXXXXXXXXX"+loanNumber); return null; }
