spring cloud雲服務架構 - eureka 項目構建過程

上一篇咱們回顧了關於 spring cloud eureka的相關基礎知識，如今咱們針對於HongHu cloud的eureka項目作如下構建，整個構建的過程很簡單，我會將每一步都構建過程記錄下來，但願能夠幫助到你們：

1. 建立一個名爲particle-common-eureka的maven項目，繼承particle-commonservice，具體的pom.xml配置文件以下：

<?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>
			<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. 在啓動類入口引用eureka的相關配置，代碼以下：

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 默認端口爲：8761)
server:
  port: 8761
 
# spring
spring:
  application:
    name: particle-commonservice-erueka
 
# eureka
eureka: 
  client: 
    # 是否註冊到eureka
    register-with-eureka: true
    # 是否從eureka獲取註冊信息
    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}
      
  # 指定環境
  environment: dev
  #指定數據中心
  datacenter: honghu
  # 關閉自我保護模式
  server: 
    enable-self-preservation: false
  #設置清理無效節點的時間間隔，默認60000，便是60s
    eviction-interval-timer-in-ms: 60000
 
# 服務認證
security: 
  basic: 
    enabled: true
  user: 
    name: honghu
    password: 123456
 
management:
  security:
    enabled: false

4. 增長項目的log機制和打包運行機制（後面咱們會詳細編寫針對於Linux Centos下的打包部署機制）

從如今開始，我這邊會將近期研發的spring cloud微服務雲架構的搭建過程和精髓記錄下來，幫助更多有興趣研發spring cloud框架的朋友，你們來一塊兒探討spring cloud架構的搭建過程及如何運用於企業項目。
