创建项目

生成一个主maven项目

mvn archetype:generate -DgroupId=com.edurt.slis.slisec -DartifactId=spring-learn-integration-springcloud-eureka-code -DarchetypeArtifactId=maven-archetype-quickstart -Dversion=1.0.0 -DinteractiveMode=false

删除生成文件中的src源码目录下的所有源码
修改pom.xml配置文件为以下内容

<?xml version="1.0" encoding="UTF-8"?>

         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

我们首先引入了spring-cloud-starter-netflix-eureka-server依赖,这样的话我们才能使用eureka服务.

创建一个java类用于做为程序的启动入口(SpringCloudIntegrationEurekaCodeLaunch.java)

package com.edurt.slis.slisec;

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

@SpringBootApplication
@EnableEurekaServer
public class SpringCloudIntegrationEurekaCodeLaunch {

    public static void main(String[] args) {
        SpringApplication.run(SpringCloudIntegrationEurekaCodeLaunch.class, args);
    }

}

此时该应用通过使用**@SpringBootApplication注解可以成为SpringBoot应用,使用@EnableEurekaServer**注解应用将成为Eureka Server.

为了方便后期其他应用接入进来我们创建一个应用的配置文件

在resources资源目录下创建一个application.properties和application-eureka.properties的配置文件,内容如下

application.properties

# 服务端口
server.port=1001

application-eureka.properties

# eureka实例配置
custom.eureka.instance.hostname=localhost
custom.eureka.client.register-with-eureka=false
custom.eureka.client.fetch-registry=false

创建使用自定义配置文件的配置类

我们经过查看eureka的源码文件后发现eureka server和eureka client的配置信息核心是依靠EurekaServerConfigBean和EurekaClientConfigBean这两个bean注入进来的,那么我们需要使用自定义的一些配置信息/文件的话,我们只需要重新设置这两个bean即可实现定制化eureka使用自定义配置文件.

在src/main/java/com/edurt/slis/slisec目录下新建config文件夹,并在该文件夹下创建EurekaServerConfig配置文件,内容如下:

@Configuration
@PropertySource(value = "application-eureka.properties")
public class EurekaServerConfig {

    @Value(value = "${custom.eureka.instance.hostname}")
    private String hostname;

    @Value(value = "${custom.eureka.client.register-with-eureka}")
    private Boolean registerWithEureka;

    @Value(value = "${custom.eureka.client.fetch-registry}")
    private Boolean fetchRegistry;

    @Bean
    @Description(value = "使用自定义配置进行配置eureka server服务")
    public EurekaServerConfigBean eurekaConfig() {
        EurekaServerConfigBean config = new EurekaServerConfigBean();
        return config;
    }

    @Bean
    @Description(value = "使用自定义配置进行配置eureka client服务")
    public EurekaClientConfigBean eurekaClientConfigBean() {
        EurekaClientConfigBean config = new EurekaClientConfigBean();
        config.setRegisterWithEureka(registerWithEureka);
        config.setFetchRegistry(fetchRegistry);
        return config;
    }

}

修改配置文件后重启服务打开浏览器就可以看到eureka的UI页面.

当然eureka server和eureka client的配置不是简简单单的我文中写的两个配置,具体的配置类可以参考进入EurekaServerConfigBean和EurekaClientConfigBean源码文件中查看.

打包文件部署
