#hystrix超时设置
hystrix.command.default.execution.isolation.thread.timeoutInMillisceconds=20000
 
ribbon.ConnectTimeout=5000
ribbon.ReadTimeout=5000
 
#重试次数
ribbon.MaxAutoRetries=1
#寻找一个服务重试
ribbon.MaxAutoRetriesNextServer=1
 
 
ribbon.OkToRetryOnAllOperations=true

　　调用http://127.0.0.1:1005/product-service/product/testFirst/777服务

 

这里的网关没有自定义超时，所以使用了默认配置

这里的超时可以如图设置

@RestController
@RequestMapping("/product")
@Slf4j
public class ProductController {
 
    @GetMapping("/getProduct/{id}")
    public String selectProduct(@PathVariable String id){
        log.info("【调用服务者入参】:{}",id);
        return "查询到的主键返回"+id;
    }
 
 
    @GetMapping("/testFirst/{id}")
    public String testFirst(@PathVariable Integer id){
        log.info("【调用服务者入参】:{}",id);
        try {
            Thread.sleep(4000L);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        StringBuilder stringBuilder=new StringBuilder();
        stringBuilder.append("qwe");
        stringBuilder.append("-");
        stringBuilder.append(id);
        return stringBuilder.toString();
    }
}

　　zuul网关配置超时设置后，请求的数据不是很快返回回来，会稍微等会

 

 本次的测试中需要一个注册中心，一个zuul网关配置，一个服务提供者

　　而当有第三方服务调用商品服务会出现超时问题

 

 这个因为订单服务默认的超时不够用了

需要在订单服务中配置如下参数

ribbon.OkToRetryOnAllOperations=true

　　

 

 就是自定义设置后，默认的超时时间变长了
