spring cloud云服务架构 - HongHu commonservice-eureka 项目构建过程

上一篇我们回顾了关于 spring cloud eureka的相关基础知识，现在我们针对于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>

<groupId>com.ml.honghu</groupId>
<artifactId>particle-commonservice</artifactId>
<version>0.0.1-SNAPSHOT</version>
</parent>
 
<artifactId>particle-commonservice-eureka</artifactId>
<packaging>jar</packaging>

</executions>
<configuration>

</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）

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。
