Fegin 卡住，阻塞，直至超时

一、错误信息

<properties>
    <spring-boot.version>2.2.6.RELEASE</spring-boot.version>
    <spring-cloud-commons.version>2.2.2.RELEASE</spring-cloud-commons.version>
    <spring-cloud-openfeign.version>2.2.2.RELEASE</spring-cloud-openfeign.version>
    <spring-cloud-alibaba.version>2.2.0.RELEASE</spring-cloud-alibaba.version>
</properties>

调用时阻塞，跟设置超时时间没有关系，无论多久都是一直阻塞，直至超时报错

感觉流程上应该没有什么问题，好像与用的环境 SpringCloudAlibaba 版本有关，或者与用的 OpenFegin 有关

二、ConsumerController

@RestController
public class OrderController {

    @Autowired
    private FeignService feignService;

    @PostMapping("/test")
    public String test(@RequestBody String text) {
        return feignService.test(text);
    }
}

三、 Consumer Service

@FeignClient("order-service")
public interface FeignService {

    @PostMapping("/api/test")
    String test(@RequestBody String text);

}

四、Provider Controller

@RestController
@RequestMapping("/api/test")
public class TestController {

    @PostMapping("/")
    public String test(@RequestBody String text) {
        return "I say " + text;
    }

}

如果确认超时时间配置正常的话，看下你的服务能不能正常访问。是不是都正常注册

问题解决了吗？同样问题。

解决这个问题了嘛
