求助大神帮忙看看,关于feign调用的一个问题,卡在那里直到超时 5C

启动类⬇

package com.tz;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.feign.EnableFeignClients;

@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients(basePackages= {"com.tz"})
public class EurekaServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(EurekaServerApplication.class, args);
    }

}

feign接口⬇

package com.tz.services;

import org.springframework.cloud.netflix.feign.FeignClient;
import org.springframework.stereotype.Service;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@FeignClient(name="compute-service")
public interface ITestFeign {
    @RequestMapping(value = "feignTest", method = RequestMethod.GET)
    public String testFeign();
}

feigin接口的实现类⬇

package com.tz.services.impl;

import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;

import com.tz.services.ITestFeign;

@Service
public class TestFeign implements ITestFeign {
    @Override
    public String testFeign() {
        return "测试feign调用";
    }

}

Controller⬇

package com.tz.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

import com.tz.services.ITestFeign;
import com.tz.services.impl.TestFeign;
import com.tz.vos.TestVo;

import org.apache.log4j.Logger;

@RestController
public class ClientController {
    private final Logger logger = Logger.getLogger(getClass());
    @Autowired
    private ITestFeign testFeign;

    @RequestMapping(value = "feignTest", method = RequestMethod.GET)
    //@ResponseBody
    public String testFeign() {
        logger.info("======testFeign========");
        String str = testFeign.testFeign();
        logger.info("======str========"+str);
        return str;
    }
}


spring.application.name=compute-service
server.port=2222
eureka.client.serviceUrl.defaultZone=http://localhost:1111/eureka/
hystrix.command.default.execution.timeout.enabled=true
hystrix.threadpool.default.coreSize=500000
hystrix.command.default.circuitBreaker.requestVolumeThreshold=1000
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=300000
ribbon.ConnectTimeout=3000
ribbon.ReadTimeout=3000
eureka.client.fetch-registry=true
eureka.client.register-with-eureka=true
logging.level.root=debugger

调用之后就一直报超时,也不知道什么原因,请大神帮我看看,谢谢。

3个回答

@FeignClient(name="compute-service")
public interface ITestFeign {
@RequestMapping(value = "feignTest", method = RequestMethod.POST)
public String testFeign();
}
试下

@FeignClient(name="compute-service" url="加上feignTest接口的前面的请求路径")
例如 :
feignTest接口请求路径:http://localhost:1111/compute-service/feignTest
url = "http://localhost:1111/compute-service/"

SpringCloud Feign调用返回结果封装后异常问题
我一个项目采用SpringCloud框架,服务端客户端采用Feign调用。 服务端返回结果封装了一个Result对象来进行包装 ![图片说明](https://img-ask.csdn.net/upload/201911/15/1573789530_208977.png) ![图片说明](https://img-ask.csdn.net/upload/201911/15/1573789552_561331.png) ![图片说明](https://img-ask.csdn.net/upload/201911/15/1573789566_505603.png) 然后服务端的一个登录方法 ![图片说明](https://img-ask.csdn.net/upload/201911/15/1573789576_928948.png) 客户端用Feign调用 ![图片说明](https://img-ask.csdn.net/upload/201911/15/1573789587_486238.png) 但是测试的时候,无论服务端返回各种结果都是报错,报枚举类超出范围异常,Feign已拿到值,但是都是报那个Code的超出枚举类异常,但是枚举类是已经定义了。 ![图片说明](https://img-ask.csdn.net/upload/201911/15/1573789601_125790.png) 麻烦各位大神能帮忙看看解决一下嘛,谢谢各位大神

Spring clouud eureka feign调用问题
最近在学习使用spring cloud 的时候遇到这样一个问题,项目划分了3个模块 注册中心、服务提供方、服务消费方. 分别启动3个项目后 在注册中心的web管理页面 能看到服务提供方和服务消费方都已经注册上来了。但是 当服务消费方调用方法时,通过日志看到是以服务提供方的别名为IP地址发起调用的 一调用就报错 请各位大神们帮忙看看 最好能给我讲讲为什么会出现这个问题 注册中心启动类 ```/**

feign 调用其他服务将接口打jar包还是通过接口重写一样的接口进行调用
请问 一下 feign 调用其他服务, 一般通过对方服务将接口打jar包,通过依赖jar使用;还是通过需要什么接口重写一样的接口进行调用,哪一种是比较推崇的?
springcloud oauth2 微服务之间同feign调用,产生invalid_token
使用的是auth2的方式进行微服务的授权, 获取到token后调用服务都正常,但是如果服务之间通过feign互相调用, 就会出现token不正确的问题,生产者一方会出现如下警告: WARN 22880 --- [nio-8200-exec-2] o.s.b.a.s.o.r.UserInfoTokenServices : Could not fetch user details: class org.springframework.beans.factory.BeanCreationException, Error creating bean with name 'scopedTarget.oauth2ClientContext': Scope 'session' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton; nested exception is java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread?

spring cloud feign 启用hystrix引发的调用问题
版本: spring cloud :Edgware.SR3(使用 spring cloud starter openfeign 1.4.4) springboot :1.5.12 问题: 我使用feign.hystrix.enable=true.启用了hystrix,然后我需要的效果是达到设置的超时时间才需要进入feignclient 注解的fallback方法. 但是!!!现在我只要一启用了feign.hystrix.enable=true这个配置,进行调用时,直接进入了fallback方法.然而我手动配置的超时时间不生效. 使用的配置如下: ``` feign: hystrix: enabled: true okhttp: enabled: true httpclient: enabled: false hystrix: threadpool: default: coreSize: 500 maxQueueSize: 1000 queueSizeRejectionThreshold: 800 command: default: execution: timeout: enabled: true isolation: thread: timeoutInMilliseconds: 60000 ribbon: eureka: enabled: true ReadTimeout: 60000 ConnectTimeout: 60000 ``` </br> 请大家帮忙看看.Thx
spring微服务调用,没有注册中心也能用吗?
几个spring微服务的问题,请指教: 1、springboot开发用RestTemplate和feign方式,如果没有部署注册中心,也可以调用吧,也可以分布式部署微服务?那么很多场景下用户不需要对服务调用进行细粒度管控,是否可以不部署注册中心? 2、如果部署了注册中心如Eureka,是否所有controller都会被注册?注册中心会记录服务的调用情况包括日志等,那么正常从浏览器和APP发起的调用也会被记录吗? 3、服务提供者和消费者都要注册到注册中心,那么从浏览器和APP发起的调用应该没有注册消费者吧?这样注册中心的服务调用管理并不全面吧?是只包括微服务之间的调用吧?是否应只注册需要被其它微服务调用的controller而不是全部? 4、服务调用好像都是调用controller,能否调用其它微服务应用的service层?controller通常是为前端调用设计的,参数是DTO,而service的参数是DO|PO,在写业务时,可能更多使用后者。 5、用RestTemplate调用服务时,@LoadBalanced注解可实现负载均衡,如果没有部署注册中心,调用时直接写的服务方地址,怎么可能实现负载均衡呢?是否@LoadBalanced必须和注册中心一起用?没有注册中心的情况下如果一个微服务部署多个实例,我们是在nginx中配置集群的,调用地址就是集群的域名,即负载均衡是由nginx实现的,spring的负载均衡是由什么实现的?
springcloud feign 找不到服务 value 和 url
找到原因了 eureka没有注册外网ip ,feign根据拿到的ip 不是正确的ip ------------------------------------------------------------ 服务提供者 和 消费者 部署在一台机子上 什么问题都没有 但是部署在2台机子时 feign超时 ribbon.ReadTimeout 和ribbon.ConnectTimeout 都已经调到很大了(我觉得是找不到微服务) 这时 把@FeignClient 的value 换成 url 不通过微服务名字 直接通过 ip和端口 不到1秒可以找到 通过value 微服务名字 ribbon.ReadTimeout设置10秒还是找不到 (微服务 服务方可以正常调用 , 注册中心 服务名字 和 feign的value 也是一样,部署在同一个机子上没出现问题) . ![图片说明](https://img-ask.csdn.net/upload/202001/10/1578631480_878086.jpg) . ![图片说明](https://img-ask.csdn.net/upload/202001/10/1578631488_570309.jpg) . ![图片说明](https://img-ask.csdn.net/upload/202001/10/1578631495_458488.jpg) . ![图片说明](https://img-ask.csdn.net/upload/202001/10/1578631501_347676.jpg)

feign怎么携带cookie访问
我在一个系统中登录成功后,需要调用本地服务接口,但是本地服务接口需要验证登录,由于feign的内网调用效率高 所以采用feign,但是现在总是提示登录失效。所以想请教下大神们,有没有知道怎么让feign携带登录后的cookie访问的方法?
Feign在开启Hystrix后,feign.client超时时间设置有什么用?
1、Feign开启Hystrix 配置文件如下: ``` feign: hystrix: enabled: true ``` 2、配置feign客户端超时时间: ``` feign: client: config: default: connectTimeout: 8000 readTimeout: 10000 ``` 请求一个休眠6秒的接口,会超时。 3、当配置Hystrix超时时间后,能正常访问,配置如下: ``` hystrix: shareSecurityContext: true command: default: execution: isolation: thread: timeoutInMilliseconds: 8000 ``` 请问:feign.client的超时时间配置有什么用?

Searching Treasure in Deep Sea 深度搜索
Problem Description A deep-sea salvage company found out that there was a sunken ship in some deep-sea area of the Pacific with a case of priceless treasure in it. The senior leaders concluded as followed: There may be some sea monsters, they may cause some distraction. The company had some most advanced intelligent underwater robots. They were equipped with enough weapons to kill the monster. After they research a map, they got information as follow (according to the Sample Input): S indicated the starting place. E indicated the place of the treasure case. D indicated the doors of the rooms in the ship. K indicated the keys which were needed while opening the doors. H indicated the stairs went up. L indicated the stairs went down. "#" indicated the walls which separated the rooms. Every lowercase in the map indicated a monster. The enclosed space formed by the doors and the walls was called a separated room. Entering a room needed a key K to open a door D. After that, the key could not be used any more, the door would be open for ever, and there would be no need to use the key. The total number of rooms in the ship was not exceeding 30, the total number of the monsters in the ship was not exceeding 26, and the number of the monsters in each room would not exceed 3. There was no monster in the rooms where S and E, H and L were in. The advanced intelligent underwater robot carried a machine gun whose cartridge clip capacity was 100 bullets and enough spare ammunition. It could re-load the bullets if given a chance. The surface of its body was equipped with 100 components. If all the components were destroyed while fighting with the monster, the robot could not function any more and would sink into the sea for ever. If only a part of the components was destroyed, the robot could recover if given a chance.The robot could attack the monsters in two ways; one is feign attack, and the other fierce attack. The feign attack would cause 1 reduction of the monsters' life value, and the fierce attack would cause a certain amount of deduction of the monsters' life value according to the degree of the fierce attack. The robot had 10 kinds of fierce attack tactics at most. Every attack tactics differed in bullet consumption and the certain reduction of the monsters' life value. For example, a certain kind of attack tactics would consume 30 bullets, and reduce 35 life value of the monster. The life of the monster was so limited that when the injuries accumulated to a certain amount it would be killed. Suppose its life value was 100, and every attack would reduce a certain amount of life value. When robot enters the treasure vessel, it searches the rooms one by one. As soon as it encounters the monsters, it will attack the monsters immediately. By consuming a certain amount of ammunition, a certain amount of the life value of the monsters is reduced. And then, the monsters attack the robot and destroy a certain number of robot's parts. Then they attack each other alternately like this. However, each time the robot launches attack firstly. If there are two or more monsters, the robot must kill the first one before another attack, and the monsters won't help each other in the battle. The choice of the order of attack is decisive when a number of monsters are in a room, because it closely relates with the final result of this battle. The robot itself and machine guns it takes possess the capacity of restoration. The robot will re-load 2 bullets when it launches an attack. In the same room, the robot will repair 10 damaged parts of the body surface and re-filled cartridges after it kills a monster. The robot can't leave the room until all monsters are eradicated. At the time he leaves the room, 100 damaged parts are repaired and 100 cartridges are refilled again. It should be noted that, under no circumstances will the robot's parts and bullets of cartridges be more than 100. Now intelligent underwater robot has been put into the sea, gradually approaching the location of the treasure vessel. Whether it can eradicate deep-sea monsters, and return the treasure box is the problem that you are supposed to resolve. Input There are several test cases. The first line of each case has 3 positive integers k, n and m (1 <= k <= 3, 1 <n, m <= 100), indicating that the deep-sea shipwreck is of k floors, each floor is a maze composed by n rows and m columns. (The Sample Input map is seen as below). That is, the maze is composed by characters of n lines, and each line has m characters. The following line has an integer p (0 <= p <= 10), indicating that there are p kinds of fierce attack tactics for the robot. Then there are a lines and each line has two positive integers, indicating the consumption of the number of bullets and reduction of the life value of the monsters as a result of injury by the robot's tactics. Then there is an integer q (0 <= q <= 26) taking up one line to indicate that there are q monsters in the treasure vessel. The following are q lines, and each line has one positive integer, indicating the number of damaged parts of the robot by those q monsters for one attack. Monsters are expressed in lowercase letters which are formed as a sequential increase from latter "a" to the letter "z". For example, when q = 10, then the names of the monsters are a, b, c, d, e, f, g, h, i, j, then the 10 lines of positive integers are the number of destroyed parts of robot as the result of the attack of those 10 monsters. Finally, there are k * n lines, every n lines indicates a floor of the ship, each line has m characters. The K floors are given from high to low. Input is terminated by the end of the file. Output For Each test case, if it can arrive "E" place, then output "Yes", or output "No". Each output takes up one line. Sample Input 1 5 10 0 0 ########## #S #K # E# #  #K #  # #  D  D  # ########## 3 5 10 1 1 10 3 1 2 3 ########## #  #aKKKK# #LKDcKKKK# ####bKKKK# ########## ########## #    DL K# #H ####### #  D  D E# ########## ########## #        # #  H     # #  S     # ########## Sample Output No Yes

Feign接收可以忽略大小写吗?FeignClient调用远程接口,如果对方接口的返回报文的属性是大写字母开头,就无法映射到定义的实体对象。
Feign接收可以忽略大小写吗?FeignClient调用远程接口,如果对方接口的返回报文的属性是大写字母开头,就无法映射到定义的实体对象。实体定义成首字母大写也不行。只能用Object和String接收,有解决方案吗? 比如对方返回的结果是: {"Data":"测试1"Code":0,"Message":"成功"} 这样无法解析: ``` @Data @Builder @AllArgsConstructor @NoArgsConstructor public class TestDto { private String data; private Integer code; private String message; } ``` 这样也无法解析: ``` public class TestDto { private String Message; private String Code; private String Data; public String getMessage() { return this.Message; } public void setMessage(String Message) { this.Message = Message; } public String getCode() { return this.Code; } public void setResultType(String Code) { this.Code = Code; } public String getData() { return this.Data; } public void setData(String Data) { this.Data = Data; } } ```
springcloud feign 注解 RequestLine 相对于 RequestMapping有什么优势吗?
目前springcloud项目 对外暴露的接口上面url用@requestMapping注解的, 但是我觉得用RequestLine更合适 因为这是Feign的注解,对外暴露也是用Feign的,请问 如题,注解 RequestLine 相对于 RequestMapping有什么优势吗?
feign的使用以及zuul是否与feign在功能上重复了
``` 一个项目里如果有客户端A,B,C,D。 是只需要将其中一个客户端配置成feign客户端, 还是应该额外提供一个feign客户端, 或者不额外提供feign客户端, 而是将所有客户端都配置成feign客户端。 如果说每个客户端都是feign客户端的, 那么对于另外的zuul客户端(非feign)来说, zuul的两个主要功能:负载均衡和流量入口,其中的负载均衡功能是否与feign功能重复了? ```
