希望作者能更改sc-f-chapter8 成kafka 实现的例子

如标题所述，按照博客编写后，打印出来只有时间，没有参数值，有人有相同的情况么？

如题，如果配置了refresh，则会刷新请求端口所在服务，如果配置其他，则无法刷新，只有配置bus-refresh才有效，是有在哪个依赖中指定的吗，求解。

提示容器中有不止一个该类

请问 正式项目中会如何使用Feign 的断路器

请问教程里面的图使用什么软件画的，谢谢。

error：
FactoryBean threw exception on object creation; nested exception is java.lang.IllegalStateException: No Feign Client for loadBalancing defined. Did you forget to include spring-cloud-starter-netflix-ribbon?

按照第一篇教程的步骤，我在创建了eureka-server的module的时候，module下的pom文件修改后引入依赖失败。

dear 大神。

第三篇: 服务消费者（Feign）
启动service-hi 两次，端口分别为8762 、8773
我这边第二次启动的时候会将上一次启动的服务关闭掉。
(
'EurekaClientApplication' is single-instance run configuration.
Are you sure you want to stop the running one?
)
该怎么解决。

Thanks & Best Regards

是需要先打jar包,然后在命令行启动是吧?但是我打了jar包以后启动报错,可以帮忙看一下吗?
Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.SecurityException: Invalid signature file digest for Manifest main attributes

1.feign接口定义：
public interface ICommonServiceApi {
@RequestMapping(value = "/list",method = RequestMethod.GET)
List getList(@RequestHeader("count") Integer count);
}
2.服务实现：
@RestController
public class UserCommerApiController implements ICommonServiceApi {
@OverRide
public List getList(Integer count){
List list = new ArrayList<>();
for (int i = 0 ;i < count ;i++) {
User user = new User("jlc_" + i,i);
list.add(user);
}
return list;
}
}
3.消费者实现：
@component
@FeignClient(name = "service-user",fallback=CommonFeignServiceImpl.class )
public interface ICommonFeignService extends ICommonServiceApi{
}

public class CommonFeignServiceImpl implements ICommonFeignService{
@OverRide
public List getList(Integer count) {
System.out.println("调取list出问题===========");
return new ArrayList();
}
}

4.消费者controller实现：
@RestController
public class FeignCommonApiController {
@RequestMapping(value = "/allc",method = RequestMethod.GET)
public String feignConsumer2(){
System.out.println("测试带参数");
System.out.println(iCommonFeignService.getList(new Integer(6)).size() + "-------------------");
return "over";
}
}

最后通过 http://localhost:端口/allc 调用，报错误：
feign.FeignException: status 404 reading ICommonFeignService#getList(Integer); content:
{"timestamp":1529836681332,"status":404,"error":"Not Found","message":"No message available","path":"/list"}

感觉 /list 没声明出去，请帮忙看看什么原因

SpringCloudLearning/chapter3/service-feign/src/main/java/com/forezp/service/SchedualServiceHi.java

应该在类首声明 @Service

书上都是配置的ribbon 和feign 熔断监控，为什么我看示例(Finchley版本)里是只是服务client的实例，为何配置配置的ribbon 和feign下 的熔断监控和Trubine 配置 查找了相关资料，不知道怎么搞？

我用idea打开chapter 5发现maven dependences里spring-cloud-starter-eureak-server:1.3.0.RC1这个包是红色的
在project stucture->libraries也看这个包是红色的，我删除掉这个包重新引也还是红色的

源码启动就报错，那位大神可以帮忙看看，非常感谢！

com.sun.jersey.api.client.ClientHandlerException: java.net.ConnectException: Connection refused: connect

spring.cloud.config.uri= http://localhost:8888/ 该参数不能修改
经查，需要新建一个bootstrap.properties文件，在其中添加
spring.cloud.config.uri= http://localhost:8888/ 并修改。
经测试，有效。这是什么原因产生的？

chap4的service-feign的熔断器配置加下面一段：

feign:
hystrix:
enabled: true

springboot2.0.3.RELEASE无法启动项目
需更换2.3.1.RELEASE版本

我自己写demo的时候总是报错，不得已fork了你的项目，然后一次成功。 我详细对比后发现就是spring cloud的版本引起的问题。 希望大神能够再写一篇文章讲讲这个版本的事情，在网上这个资料也非常少。

为啥在application.yml配置文件里并没有打开熔断器的配置,而且照着你的教程来无法实现效果

sfc-chapter-12 工程运行，hystrix dashborad出现错误Unable to connect to Command Metric Stream，hystrix dashboard请求路径为：http://localhost:8762/actuator/hystrix.stream，

请问怎么解决这个问题

debug模式进不到redisratelimiter中去，redis中也没数据

我用的eclipse,不是idea。控制台报错是

.....................
其中三个文件（pom.xml ConfigServerApplication.java application.properties）都是直接从https://github.com/forezp/SpringCloudLearning/tree/master/chapter6/config-server拖过来的，运行起来也没报错。但是访问就报错。

首先全文被折叠，其次广告一堆，再者样式看着不那么舒服，可以试试掘金的链接

当没在bootstrap.yml里面配置server port时，就默认是8080端口了
有人遇到这个问题？

Hystrix 仪表盘在Feign服务中不能用

界面是可以的，不过输入stream后 提示：

Unable to connect to Command Metric Stream.

根据其他博主说的要加上@EnableCircuitBreaker。可是反而整个Feign服务跑不起来了

这里是不是只要run config-server 一个模块?

我fork了本项目
git的配置 然后改成
spring.cloud.config.server.git.uri=https://github.com/hiei17/SpringCloudLearning/
spring.cloud.config.server.git.searchPaths=respo
spring.cloud.config.label=master
spring.cloud.config.server.git.username=hiei17
spring.cloud.config.server.git.password=我的登录密码

https://www.fangzhipeng.com/springcloud/2018/08/09/sc-f9-sleuth.html

4.3 创建service-miya中“创建过程痛service-hi”应改为“创建过程同service-hi”

这样01-14能够按顺序排序，而不会出现1，11，12，13，14，2，3的情况

这个要改pom.xml才跑的起来，exclude掉tomcat

org.springframework.boot
spring-boot-starter-web


org.springframework.boot
spring-boot-starter-tomcat

您好，关于springcloud部署，您有空的话可以讲解一下吗

feign无法传多个实体 和文件 如何解决 请问教程里面有吗

@forezp 大神帮我看看什么问题

服务端config-server返回的结果

客户端启动时报的错误

客户端controller代码

如果不用@value取值,直接赋值,程序正常运行

Description:

The bean 'proxyRequestHelper', defined in class path resource [org/springframework/cloud/netflix/zuul/ZuulProxyAutoConfiguration$NoActuatorConfiguration.class], could not be registered. A bean with that name has already been defined in class path resource [org/springframework/cloud/netflix/zuul/ZuulProxyAutoConfiguration$EndpointConfiguration.class] and overriding is disabled.

Action:

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

配置都是按照教程来的呀
加上 spring.main.allow-bean-definition-overriding=true 依然报错

spring容器直接读取的 .properties，没有走config-center

https://www.fangzhipeng.com/springcloud/2018/08/12/sc-f12-dash.html

四、Hystrix Dashboard图形展示,第二段

打开locahost:8762/hystrix 可以看见以下界面

其中的localhost单词拼写错误

springboot版本已换成2.0.3
报错信息:
Description:

The bean 'proxyRequestHelper', defined in class path resource [org/springframework/cloud/netflix/zuul/ZuulProxyAutoConfiguration$NoActuatorConfiguration.class], could not be registered. A bean with that name has already been defined in class path resource [org/springframework/cloud/netflix/zuul/ZuulProxyAutoConfiguration$EndpointConfiguration.class] and overriding is disabled.

Action:

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true
查了一下一直说版本不正确，找不到问题了

增加如下配置:
management.endpoints.web.exposure.include=hystrix.stream
management.endpoints.web.base-path=/actuator
该配置的意思是指定hystrixDashboard的访问路径，SpringBoot2.x以上必须指定，不然是无法进行访问
ps:在firefox访问会弹出下载框.....

博客里很多插图无法访问

我是一个 spring-cloud 的初学者。
有个问题请教下，如果看到，帮我回答下，谢谢！

1. 对于 spring-cloud 架构，如果是前端 页面 请求，则是不是 直接经过 zuul 网关 路由到服务提供方，而不用经过 ribbon， 或者 feign 客户端再调用一次， 不过不经过客户端的话，那 对 服务 的负载均衡 就没地方做，我的理解是否合理？

2. 如果是服务之间调用，则通过客户端直接调用，要不要再经过网关路由？

真实的项目架构是怎么样的一个设计，能帮我解答下吗，谢谢
