不是已经检索出来了吗?为什么不能获取呢?
请大神指教,谢谢

更新:
测试查看了 instances 的长度,结果发现是0。。。

2个回答

报的错误是数组越界,但是你取的是第0个元素所以集合应该是空的,建议打印一下instances的长度,并在下面的打印时做判空处理。检查一下你要获取的微服务的实例名称,应该是没写对。
补充:找到要获取的实例的项目中的yml配置文件,找到

Spring:
    application:
        name:

属性的值,将getInstances()中的值改为这个,这个是你要获取的微服务对外暴露的名称,通过这个名称获取实例。

docker宿主机随机端口映射了docker容器,如何让docker容器知道宿主机的IP与映射端口呢?
本人使用springcloud+docker的结构搭建微服务,现在遇到的问题是: docker宿主机使用-P命令随机端口绑定的docker指定端口(比如每个容器都暴露8080端口), 但是容器中无法知道宿主机的ip和映射端口,即eureka上的实例不知道暴露给外部的什么访问IP和端口(宿主机IP和宿主机port)。 请教各位大神,此问题该如何解决,谢谢! **【docker显示宿主机的随机端口32773映射了容器8080端口】** ![图片说明](https://img-ask.csdn.net/upload/201908/11/1565453714_366300.png) **【Eureka显示是容器端口8080,而非宿主机映射端口】** ![图片说明](https://img-ask.csdn.net/upload/201908/11/1565453818_448472.png)

微服务网关访问Controller报404异常
微服务通过zuul网关访问controller报404,直接URL可以访问![图片说明](https://img-ask.csdn.net/upload/202002/05/1580878257_918122.png)![图片说明](https://img-ask.csdn.net/upload/202002/05/1580878271_404575.png) ![图片说明](https://img-ask.csdn.net/upload/202002/05/1580878227_376926.png) 网关配置如下: ``` eureka: client: registry-fetch-interval-seconds: 5 service-url: defaultZone: http://localhost:8090/eureka server: port: 8092 #网关端口号 spring: application: name: zuul-service #网关服务名称 zuul: prefix: /api routes: #路径列表 zuulservicehello1: path: /zuulservicehello1/** service-id: HELLO1 strip-prefix: false retryable: true add-proxy-headers: false sensitive-headers: add-host-header: true ``` 解析后的yml: ``` { eureka: { client: { 'registry-fetch-interval-seconds': 5, 'service-url': { defaultZone: 'http://localhost:8090/eureka' } } }, server: { port: 8092 }, spring: { application: { name: 'zuul-service' } }, zuul: { prefix: '/api', routes: { zuulservicehello1: { path: '/zuulservicehello1/**', 'service-id': 'HELLO1', 'strip-prefix': false } }, retryable: true, 'add-proxy-headers': false, 'sensitive-headers': null, 'add-host-header': true } } ``` 服务配置: ``` eureka: client: registry-fetch-interval-seconds: 5 service-url: defaultZone: http://localhost:8090/eureka server: port: 8095 #后台服务端口号 spring: application: name: HELLO1 ``` 解析后的yml ``` { eureka: { client: { 'registry-fetch-interval-seconds': 5, 'service-url': { defaultZone: 'http://localhost:8090/eureka' } } }, server: { port: 8095 }, spring: { application: { name: 'HELLO1' } } } ``` 服务程序代码: ``` package com.example.springboot.controller.Demo; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.RestController; @RestController() public class HelloWorld { @RequestMapping("/hello") public String Hello(){ return ("HelloSpringCloud"); } } ``` 注册中心配置 ``` eureka: client: service-url: defaultZone: http://localhost:8090/eureka/ register-with-eureka: false fetch-registry: false service: enable-self-preservation: false server: port: 8090 #eureka注册中心端口号 ``` 通过URL直接访问服务程序可以访问成功,通过Zuul网关访问失败,SpringCloud初学者,求解惑!!! 补充说明路由信息是有的 ![图片说明](https://img-ask.csdn.net/upload/202002/05/1580887378_329619.png) 原因出在strip-prefix的配置,改为true问题解决,用法参照:https://blog.csdn.net/u010953880/article/details/102977884
springcloud 获取不到阿里云公网ip?
springcloud 分布式部署遇到了一些问题, 我目前有二台服务器:阿里云,和腾讯云 A、在腾讯云上用ngnix映射我的网站,代理转发eureka; B、阿里云,部署eureka和一个业务服务端z; 目前出现的问题是,我在本地启用zuul服务和feign服务,可以注册到C上的eureka服务,但是请求不到阿里云服务器B上的业务服务端z,后台打印请求的地址是阿里云的本地服务ip,而不是公网IP;我现在不知道怎么设置eureka获取公网ip,有没有大神遇到过? eureka 配置 ![图片说明](https://img-ask.csdn.net/upload/201811/30/1543574336_220483.png) zuul 配置 ![图片说明](https://img-ask.csdn.net/upload/201811/30/1543574350_480026.png)
springboot项目编译失败,无法找到主类
最近再用springcloud开发,项目结构如下 zy(父类工程,定义各模块,指定模块依赖jar版本) |------------------------------ |--config-core 核心配置类 | |-- applet-service app接口 依赖da-core | |-- manage-service 后台管理接口 依赖da-core | |-- eureka-service eureka注册中心 打包 manage-service的时候报错 ``` Failed to execute goal on project applet-service: Could not resolve dependencies for project com.zhancheng:applet-service:jar:0.0.1-SNAPSHOT: Could not find artifact com.zhancheng:config-core:jar:0.0.1-SNAPSHOT ``` 没有找到config-core,我又尝试install config-core,报错 ``` Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.1.6.RELEASE:repackage (repackage) on project config-core: Execution repackage of goal org.springframework.boot:spring-boot-maven-plugin:2.1.6.RELEASE:repackage failed: Unable to find main class ``` 没有找到主类,但是这个项目本身是没有主类的啊,主类在applet-service和manage-service. 项目是在本地能跑的,但是想打包部署到服务器上,请问应该怎么做?
(已解决)紧急求助!springboot启动服务,提示: java.net.ConnectException: Connection refused: connect
## 这个服务昨晚还可以运行的,今早启动后, 一开始提示:could not be registered. A bean with that name has already been 根据网友的说法,我设置了:_allow-bean-definition-overriding: true _ ## 然后就开始报这个错了,现在把上面这个配置注释掉也不行。。。 请大神指教! +++

Python爬虫精简步骤1 获取数据
爬虫的工作分为四步: 1.获取数据。爬虫程序会根据我们提供的网址,向服务器发起请求,然后返回数据。 2.解析数据。爬虫程序会把服务器返回的数据解析成我们能读懂的格式。 3.提取数据。爬虫程序再从中提取出我们需要的数据。 4.储存数据。爬虫程序把这些有用的数据保存起来,便于你日后的使用和分析。 这一篇的内容就是:获取数据。 首先,我们将会利用一个强大的库——requests来获取数据。 在电脑上安装
