Spring Cloud云服务架构 - commonservice-eureka 项目构建过程

Posted 2020-10-25 allalongx

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>  
            <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：

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。源码来源
