（八）微服务分布式云架构spring cloud - commonservice-eureka 项目构建过程

我们针对于HongHu cloud的eureka项目做以下构建，整个构建的过程很简单，我会将每一步都构建过程记录下来，希望可以帮助到大家：

1. 创建一个名为particle-common-eureka的maven项目，继承particle-commonservice，具体的pom.xml配置文件如下：

    <?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 http://maven.apache.org/xsd/maven-4.0.0.xsd">  
        <modelVersion>4.0.0</modelVersion>  
      
        <parent>  
            <groupId>com.ml.honghu</groupId>  
            <artifactId>particle-commonservice</artifactId>  
            <version>0.0.1-SNAPSHOT</version>  
        </parent>  
      
        <artifactId>particle-commonservice-eureka</artifactId>  
        <packaging>jar</packaging>  
      
        <name>particle-commonservice-eureka</name>  
        <description>particle-commonservice project for Spring Boot</description>  
      
        <dependencies>  
            <dependency>  
                <groupId>org.springframework.cloud</groupId>  
                <artifactId>spring-cloud-starter-eureka-server</artifactId>  
            </dependency>  
            <dependency>

            </dependency>  
            <dependency>  
                <groupId>org.springframework.boot</groupId>  
                <artifactId>spring-boot-devtools</artifactId>  
            </dependency>  
              
            <dependency>  
                <groupId>org.springframework.boot</groupId>  
                <artifactId>spring-boot-starter-test</artifactId>  
                <scope>test</scope>  
            </dependency>  
      
        </dependencies>  
      
        <build>  
            <plugins>  
                <plugin>  
                    <groupId>org.springframework.boot</groupId>  
                    <artifactId>spring-boot-maven-plugin</artifactId>  
                    <executions>  
                        <execution>  
                            <id>1</id>  
                            <goals>  
                                <goal>repackage</goal>  
                            </goals>  
                        </execution>  
                        <execution>  
                            <id>2</id>  
                            <goals>  
                                <goal>build-info</goal>  
                            </goals>  
                        </execution>  
                    </executions>  
                    <configuration>  
                        <executable>true</executable>  
                    </configuration>  
                      
                </plugin>  
            </plugins>  
        </build>  
    </project>  

　　 2. 在启动类入口引用eureka的相关配置，代码如下：

    package com.ml.honghu;  
      
    import org.springframework.boot.SpringApplication;  
    import org.springframework.boot.autoconfigure.SpringBootApplication;  
    import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;  
      
    @EnableEurekaServer  
    @SpringBootApplication  
    public class ServiceApplication {  
      
        public static void main(String[] args) {  
            SpringApplication.run(ServiceApplication.class, args);  
        }  
    }  

　　 3. 配置application.yml文件

    # server (eureka 默认端口为：8761)  
    server:  
      port: 8761  
      
    # spring  
    spring:  
      application:  
        name: particle-commonservice-erueka  
      
    # eureka  
    eureka:   
      client:   
        # 是否注册到eureka  
        register-with-eureka: true  
        # 是否从eureka获取注册信息  
        fetch-registry: false  
        availability-zones:   
          honghu: honghuZone  
        service-url:   
          honghuZone: http://honghu:123456@localhost:8761/eureka/  
          defaultZone: http://honghu:123456@localhost:8761/eureka/  
      instance:  
        prefer-ip-address: true  
        hostname: localhost  
        metadataMap:  
          zone: honghuZone  
          user: ${security.user.name}  
          password: {security.user.password}  
            
      # 指定环境  
      environment: dev  
      #指定数据中心  
      datacenter: honghu  
      # 关闭自我保护模式  
      server:   
        enable-self-preservation: false  
      #设置清理无效节点的时间间隔，默认60000，即是60s  
        eviction-interval-timer-in-ms: 60000  
      
    # 服务认证  
    security:   
      basic:   
        enabled: true  
      user:   
        name: honghu  
        password: 123456  
      
    management:  
      security:  
        enabled: false  

　　

4. 增加项目的log机制和打包运行机制（后面我们会详细编写针对于Linux Centos下的打包部署机制）

5. 自此整个项目部署完成，通过手动方式进行Run As --> Spring Boot App,运行结果如下：

控制台运行结果：

 

访问控制台并登陆：

 

控制台运行效果：

从现在开始，我这边会将近期研发的spring cloud微服务云架构的搭建过程和精髓记录下来，帮助更多有兴趣研发spring cloud框架的朋友，大家来一起探讨spring cloud架构的搭建过程及如何运用于企业项目。
