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>

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

            <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
