本文详细介绍了如何使用Spring Cloud Finchley版本搭建Eureka注册中心，并配置Eureka客户端和服务配置中心，包括安全认证设置及依赖管理，实现服务发现与配置管理。

1、Eureka-Server部分

（1）pom.xml

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        <spring-cloud.version>Finchley.SR1</spring-cloud.version>
    </properties>
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-config</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-web</artifactId>
        </dependency>
    </dependencies>

（2） application.yml

spring:
  application:
    name: eureka-server
  security:
    user:
      name: user
      password: password
server:
  port: 8761
eureka:
  instance:
    #eureka服务端配置
    prefer-ip-address: false
    #   不使用主机名来定义注册中心的地址,而使用IP地址的形式
    status-page-url-path: /actuator/info
    # 获取此实例状态页的URL路径，然后构造出主机名，安全端口等，默认为/info
    health-check-url-path: /actuator/health
    # 获取此实例的相对健康检查URL路径，默认为/health
  client:
    #eureka客户端配置
    register-with-eureka: false
    #   实例是否在eureka服务器上注册自己的信息以供其他服务发现，默认为true
    fetch-registry: false
    #     此客户端是否获取eureka服务器注册表上的注册信息，默认为true
    service-url:
      #    指定服务注册中心的地址
      defaultZone: http://user:password@localhost:8761/eureka/
#
#logging:
#  level:
#    org:
#      springframework:
#        security: DEBUG

这部分的secrity是EurekaServerd的身份认证部分

（3）启动类

@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {

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

    @EnableWebSecurity
    static class WebSecurityConfig extends WebSecurityConfigurerAdapter {

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.csrf().ignoringAntMatchers("/eureka/**");
            super.configure(http);
        }
    }
}

添加WebSecurityConfig 这段代码主要是，本版本的SpringCloud它默认启动了CSRF 这个东西，如果我们不禁用它，那么我们的url就会是错误的

2、Eureka-Client-ConfigServer

（1）pom.xml

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        <spring-cloud.version>Finchley.SR1</spring-cloud.version>
    </properties>
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-config-server</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
    </dependencies>

（2）application.yml

server:
  port: 8080
spring:
  cloud:
    config:
      server:
        git:
          uri: git@github.com:wangchunself/ymlforconfig.git
  application:
    name: eureka-client-configserver
  security:
    user:
      name: user
      password: password
eureka:
  instance:
    prefer-ip-address: true
  client:
    service-url:
      defaultZone: http://user:password@localhost:8761/eureka
    healthcheck:
      enabled: true

这块的security就是配置ConfigServer的身份认证的

（3）启动类

@EnableConfigServer
@SpringBootApplication
@EnableDiscoveryClient
public class EurekaConfigServerApplication {

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

}

3、Eureka-Client-ConfigClient

（1）pom.xml

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        <spring-cloud.version>Finchley.SR1</spring-cloud.version>
    </properties>
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-config</artifactId>
        </dependency>
    </dependencies>

（2）bootstrap.yml（必须写在bootastrap.yml中，如果写在application.yml中，它读取不到）

spring:
  cloud:
    config:
      discovery:
        enabled: true                #这块表示启用service-id不用uri
        service-id: eureka-client-configserver  #这块是服务的id
      label: master            
      profile: bar
      username: user            #这块是验证configclient身份用的
      password: password
  application:
    name: eureka-client-configclient
server:
  port: 8081
eureka:
  instance:
    prefer-ip-address: true
  client:
    service-url:
      defaultZone: http://user:password@localhost:8761/eureka
logging:
  level:
    org:
      springframework:
        security: DEBUG

（3）启动类

@SpringBootApplication
@EnableDiscoveryClient
public class EurekaConfigClientApplication {

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

}

（4）调用类

@SpringBootApplication
@EnableDiscoveryClient
public class EurekaConfigClientApplication {

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

}

4、测试

结果正确
