com.netflix.hystrix.contrib.javanica.exception.FallbackDefinitionException:

在全局默认配置服务降级方法不能加参数：

@RestController
@DefaultProperties(defaultFallback = "TimeoutAndExceptionHandler",commandProperties = {
        @HystrixProperty(name = "execution.isolation.thread.timeoutInMilliseconds",value = "3000")
})
public class PaymentHystrixController {...}

报错示例：

    
    public String TimeoutAndExceptionHandler(Integer id){
        System.out.println("服务降级处理...");
        return "线程池："+Thread.currentThread().getName()+"   paymentInfo_TimeOut"+"t"+"┭┮﹏┭┮";
    }

正确示例：

    
    public String TimeoutAndExceptionHandler(){
        System.out.println("服务降级处理...");
        return "线程池："+Thread.currentThread().getName()+"   paymentInfo_TimeOut"+"t"+"┭┮﹏┭┮";
    }
