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。

springboot2.2.0项目无法使用@EnableFeignClients已添加starter-openfeign和openfeign-core

环境: maven3.0+springboot2.2.0 想做微服务调用使用feign,启动类添加@EnableDiscoveryClient和@EnableDiscoveryClient pom文件添加: ``` <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.2.0.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.example</groupId> <artifactId>consumer</artifactId> <version>0.0.1-SNAPSHOT</version> <name>consumer</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> <version>2.1.1.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-feign</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-openfeign-core</artifactId> <version>2.0.0.RC1</version> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-openfeign</artifactId> <version>2.0.0.RC1</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project> ``` 如果不添加spring-cloud-openfeign-core,注解无法使用。 如果添加了他,启动项目时报错context找不到。 真心是无解了。。。。这springboot2.2.0怎么这么多坑

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)

在父工程pom.xml添加了一段定义springcloud版本的配置,导致其他子模块的pom报错

依下是添加的代码 <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Finchley.M9</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> 以下是报错详情。说另一个子模块common依赖出问题了。 ![图片说明](https://img-ask.csdn.net/upload/201812/28/1545926797_485433.png) 但每次只是一个或几个(不一定是哪几个)报错,其他依赖common的子模块都没报错

spring cloud中,使用security过滤关闭命令,eureka也被过滤了

spring cloud中,为关闭命令添加了security验证,但是发现eureka注册也被拦截了,返回403错误,但是security过滤的url就只有shutdown,另外发布一个测试服务,url也没被过滤可以被直接访问,但为什么eureka就被过滤了呢,哪位大神知道原因吗

关于spring-cloud-config配置中心的问题,配置可以被查询,但不能被客户端读取。

自学spring cloud 遇到难点,有些东西不是特别理解希望有大佬看到能给予一下帮助,不胜感激。 在学习配置中心文件代码如下 application.yml ``` spring: cloud: config: server: native: search-locations: classpath:/config profiles: active: native # git: # uri: https://gitee.com/zhongzunfa/spring-cloud-config.git # search-paths: V1-DEV application: name: config-server server: port: 9092 #启动端口 ``` config文件包含如下内容 ``` spring: gfp: name: "gfp" sex: 1 age: 18 ``` 可在浏览器中输入地址:http://localhost:9092/author/spring 查看到对应信息 ![图片说明](https://img-ask.csdn.net/upload/201809/03/1535976477_498619.png) 在客户端中配置类如下两个配置文件 bootstrap.yml ``` spring: cloud: config: label: master uri: http://localhost:9092/author/spring name: author ``` application.yml ``` spring: application: name: config-client-consumer server: port: 9093 ``` 再对应的属性注入部分为如下设置 ``` @Component @ConfigurationProperties(prefix = "spring.gfp") public class AuthorConfig { private String name; private Integer age; private Integer sex; public String getName() { return name; } public void setName(String name) { this.name = name; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } public Integer getSex() { return sex; } public void setSex(Integer sex) { this.sex = sex; } @Override public String toString() { return "AuthorConfig{" + "name='" + name + '\'' + ", age=" + age + ", sex=" + sex + '}'; } ``` 抛出异常为如下,非常不解如何设置, ``` com.sun.jersey.api.client.ClientHandlerException: java.net.ConnectException: Connection refused: connect at com.sun.jersey.client.apache4.ApacheHttpClient4Handler.handle(ApacheHttpClient4Handler.java:187) ~[jersey-apache-client4-1.19.1.jar:1.19.1] at com.sun.jersey.api.client.filter.GZIPContentEncodingFilter.handle(GZIPContentEncodingFilter.java:123) ~[jersey-client-1.19.1.jar:1.19.1] at com.netflix.discovery.EurekaIdentityHeaderFilter.handle(EurekaIdentityHeaderFilter.java:27) ~[eureka-client-1.9.2.jar:1.9.2] at com.sun.jersey.api.client.Client.handle(Client.java:652) ~[jersey-client-1.19.1.jar:1.19.1] at com.sun.jersey.api.client.WebResource.handle(WebResource.java:682) ~[jersey-client-1.19.1.jar:1.19.1] at com.sun.jersey.api.client.WebResource.access$200(WebResource.java:74) ~[jersey-client-1.19.1.jar:1.19.1] at com.sun.jersey.api.client.WebResource$Builder.get(WebResource.java:509) ~[jersey-client-1.19.1.jar:1.19.1] at com.netflix.discovery.shared.transport.jersey.AbstractJerseyEurekaHttpClient.getApplicationsInternal(AbstractJerseyEurekaHttpClient.java:194) ~[eureka-client-1.9.2.jar:1.9.2] at com.netflix.discovery.shared.transport.jersey.AbstractJerseyEurekaHttpClient.getApplications(AbstractJerseyEurekaHttpClient.java:165) ~[eureka-client-1.9.2.jar:1.9.2] at com.netflix.discovery.shared.transport.decorator.EurekaHttpClientDecorator$6.execute(EurekaHttpClientDecorator.java:137) [eureka-client-1.9.2.jar:1.9.2] at com.netflix.discovery.shared.transport.decorator.MetricsCollectingEurekaHttpClient.execute(MetricsCollectingEurekaHttpClient.java:73) ~[eureka-client-1.9.2.jar:1.9.2] at com.netflix.discovery.shared.transport.decorator.EurekaHttpClientDecorator.getApplications(EurekaHttpClientDecorator.java:134) [eureka-client-1.9.2.jar:1.9.2] at com.netflix.discovery.shared.transport.decorator.EurekaHttpClientDecorator$6.execute(EurekaHttpClientDecorator.java:137) [eureka-client-1.9.2.jar:1.9.2] at com.netflix.discovery.shared.transport.decorator.RedirectingEurekaHttpClient.executeOnNewServer(RedirectingEurekaHttpClient.java:118) ~[eureka-client-1.9.2.jar:1.9.2] at com.netflix.discovery.shared.transport.decorator.RedirectingEurekaHttpClient.execute(RedirectingEurekaHttpClient.java:79) ~[eureka-client-1.9.2.jar:1.9.2] at com.netflix.discovery.shared.transport.decorator.EurekaHttpClientDecorator.getApplications(EurekaHttpClientDecorator.java:134) [eureka-client-1.9.2.jar:1.9.2] at com.netflix.discovery.shared.transport.decorator.EurekaHttpClientDecorator$6.execute(EurekaHttpClientDecorator.java:137) [eureka-client-1.9.2.jar:1.9.2] at com.netflix.discovery.shared.transport.decorator.RetryableEurekaHttpClient.execute(RetryableEurekaHttpClient.java:120) [eureka-client-1.9.2.jar:1.9.2] at com.netflix.discovery.shared.transport.decorator.EurekaHttpClientDecorator.getApplications(EurekaHttpClientDecorator.java:134) [eureka-client-1.9.2.jar:1.9.2] ```
