spring-cloud,eureka客户端注册没有任何响应

spring-cloud eureka客户端不注册。spring-cloud搭建的项目,一个是eureka的服务端,然后另一个是服务提供者。但是这个服务提供者不注册。
配置文件如下:
eureka服务:pom.xml

<?xml version="1.0"?>

eureka服务的application.yml:

server:  
  #端口号 eureka服务器端口
  port: 8083 
spring:
  application: 
    name: eureka
  datasource: 
    type: com.alibaba.druid.pool.DruidDataSource
    driverClassName: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/ci?serverTimezone=PRC&characterEncoding=utf-8&useSSL=true
    username: xxx
    password: xxx
    maxActive: 20
    maxIdle: 10
    maxWaitMillis: -1
    initialSize: 5
  #main:
    #allow-bean-definition-overriding: true 
  security: # 密码配置2.1之后这样配置
    user:
      name: Hydra
      password: 19861213hkf
eureka:
  client:
    # 下面两个是非集群的配置
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: http://Hydra:19861213hkf@127.0.0.1:8083/eureka
      #默认的访问风格(未设置用户名和密码时)
      #defaultZone: http://localhost:8083/eureka/

然后是服务提供者(provider)的pom.xml:

<?xml version="1.0"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"

        <artifactId>spring-cloud-netflix-eureka-client</artifactId>
    </dependency> 
  </dependencies>
</project>

然后是服务提供者(provider)的application.yml:
server:

#端口号 eureka服务器端口

spring:

maxIdle: 10
maxWaitMillis: -1
initialSize: 5
#main:

security: # 密码配置2.1之后这样配置
user:

password: 19861213hkf
eureka:

register-with-eureka: false
fetch-registry: false
service-url:

#默认的访问风格(未设置用户名和密码时)
#defaultZone: http://localhost:8083/eureka/
两个都启动后,
然后开打127.0.0.1:8083/eureka 输入用户名和密码,界面如下(看不到注册的提供者):
图片说明

最后是我两个app的启动类:

@SpringBootApplication
@EnableEurekaServer
public class EurekaStart {

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

}

@EnableEurekaClient
@SpringBootApplication
@MapperScan("org.hydrakyoufeng.provider")
public class ProviderStart {

    /**
     * 启动j2se的springboot
     * @param args
     */
    public static void main(String[] args) {
        SpringApplication.run(ProviderStart.class);
    }
}
// 刚才代码贴掉了,这两个注解我是加了的。

我的提供者无法完成注册,日志没有任何注册相关的消息,也没有任何异常打印。

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] ```

eureka配置了spring security后,客户端启动报错,请求不到服务器

服务器端: pom.xml添加的spring security 启动类添加了@EnableEurekaServer注解 yml如下 spring: security: user: name: user password: psw123 eureka: client: service-url: defaultZone: http://user:psw123@localhost:8761/eureka register-with-eureka: false fetch-registry: false 客户端 pom添加spring-boot-starter-actuator依赖 启动类添加了@EnableDiscoveryClient注解 yml如下 eureka: client: service-url: defaultZone: http://user:psw123@localhost:8761/eureka instance: prefer-ip-address: true instance-id: ${spring.application.name}:${spring.application.instance_id:${server.port}} 服务器端启动正常,输入ip后也能通过输入用户名密码登录。但是客户端启动则报错。 com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server 如果去掉spring security验证的话客户端是能够正常注册到注册中心的。 网上服务器的yml配置(如下),我这里是没有的。我这里只有spring.security, 没有直接就security。 security: basic: enable:true name: password

无代码时代来临,程序员如何保住饭碗?

编程语言层出不穷,从最初的机器语言到如今2500种以上的高级语言,程序员们大呼“学到头秃”。程序员一边面临编程语言不断推陈出新,一边面临由于许多代码已存在,程序员编写新应用程序时存在重复“搬砖”的现象。 无代码/低代码编程应运而生。无代码/低代码是一种创建应用的方法,它可以让开发者使用最少的编码知识来快速开发应用程序。开发者通过图形界面中,可视化建模来组装和配置应用程序。这样一来,开发者直...

前几天我们公司做了一件蠢事,非常非常愚蠢的事情。我原以为从学校出来之后,除了找工作有测试外,不会有任何与考试有关的事儿。 但是,天有不测风云,公司技术总监、人事总监两位大佬突然降临到我们事业线,叫上我老大,给我们组织了一场别开生面的“考试”。 那是一个风和日丽的下午,我翘着二郎腿,左手端着一杯卡布奇诺,右手抓着我的罗技鼠标,滚动着轮轴,穿梭在头条热点之间。 “淡黄的长裙~蓬松的头发...
