SpringCloud 备忘 1 - 父工程及 Eureka 服务搭建

1、使用自己习惯的 IDE 创建一个 Maven 项目 “microservicecloud” 作为父工程

2、修改父工程 pom.xml 文件

<?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.lakey.springcloud</groupId>
    <artifactId>microservicecloud</artifactId>
    <version>1.0-SNAPSHOT</version>

    <name>microservicecloud</name>
    <description>Cloud Template</description>
    <packaging>pom</packaging>

    <!-- SpringBoot 父依赖 -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.3.RELEASE</version>
        <relativePath/> <!-- 从 Maven 仓库查找父级 -->
    </parent>

    <properties>
        <java.version>1.8</java.version>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <spring-cloud.version>Finchley.RELEASE</spring-cloud.version>
    </properties>

    <dependencies>
        <!-- SpringBoot 测试依赖 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <!-- 只引用但不引入 -->
    <dependencyManagement>
        <dependencies>
            <!-- SpringCloud 依赖 -->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <!-- 子模块，在父工程下新建子模块后自动生成，不是固定写法，仅供参考 -->
    <modules>
        <module>eureka-8101</module>
        <module>provider-8201</module>
        <module>provider-8202</module>
        <module>consumer-ribbon-8401</module>
        <module>consumer-feign-8301</module>
        <module>zuul-8501</module>
    </modules>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

 3、在父工程下新建 Module，也是 Maven 工程，名称为 “eureka-8101”

4、修改 “eureka-8101” 工程 pom.xml 文件

<?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">
    <parent>
        <artifactId>microservicecloud</artifactId>
        <groupId>com.lakey.springcloud</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>eureka-8101</artifactId>
    <name>eureka-8101</name>
    <description>Eureka 8101</description>

    <dependencies>
        <!-- Eureka 服务端依赖 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>
    </dependencies>

</project>

5、在 java 路径下创建目录 “com.lakey.springcloud” 并添加启动类 Eureka8101Application.java

package com.lakey.springcloud;

import org.springframework.boot.Banner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer // EurekaServer服务器端启动类,接受其它微服务注册
public class Eureka8101Application {

    public static void main(String[] args) {
        SpringApplication application = new SpringApplication(Eureka8101Application.class);
        application.setBannerMode(Banner.Mode.OFF);// 不输出Banner
        application.run(args);
        System.out.println("  _____   _   _   ____    _____   _  __     _       ___    _    ___    _ \n" +
                " | ____| | | | | |  _ \\  | ____| | |/ /    / \\     ( _ )  / |  / _ \\  / |\n" +
                " |  _|   | | | | | |_) | |  _|   | ' /    / _ \\    / _ \\  | | | | | | | |\n" +
                " | |___  | |_| | |  _ <  | |___  | . \\   / ___ \\  | (_) | | | | |_| | | |\n" +
                " |_____|  \\___/  |_| \\_\\ |_____| |_|\\_\\ /_/   \\_\\  \\___/  |_|  \\___/  |_|");
    }

}

6、在 resources 路径下添加配置文件 application.yml

# 服务器配置
server:
  port: 8101

# Eureka 配置
eureka:
  instance:
    hostname: localhost
  client:
    registerWithEureka: false  # false 表示不向注册中心注册自己
    fetchRegistry: false        # false 表示自己端就是注册中心，我的职责就是维护服务实例，并不需要去检索服务
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

# Spring 配置
spring:
  application:
    name: eurka
