## 一 .服务端配置 ##

*  创建 maven项目 在 pom.xml中配置 需要引入***spring-cloud-starter-eureka-server*** 依赖 和 添加 ***@EnableEurekaServer*** 注解

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.9.RELEASE</version>
    </parent>
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Dalston.SR4</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>
        </dependency>
    
    </dependencies>

*  创建一个application.yml

server:
      port: 8761
    
    eureka:
      instance:
        hostname: localhost
      client:
        registerWithEureka: false
        fetchRegistry: false
        serviceUrl:
          defaultZone: http://${eureka.instance.hostname}:${serve

*  创建一个启动类 启动项目

package cn.et;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
    
    @SpringBootApplication
    @EnableEurekaServer
    public class Main {
        public static void main(String[] args) {
            SpringApplication.run(Main.class, args);
        }
    }

## 二. 配置一个发邮件的客户端 ##

*  创建maven项目 在pom.xml中添加 发邮件的依赖jar包

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.9.RELEASE</version>
    </parent>
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Dalston.SR4</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
         <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mail</artifactId>
        </dependency>
         <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka</artifactId>
        </dependency>
    </dependencies>

*  创建一个application.properties配置文件 配置访问邮箱的参数

spring.mail.default-encoding=UTF-8
    spring.mail.host=smtp.163.com
    spring.mail.password=密码
    spring.mail.port=25
    spring.mail.protocol=smtp
    spring.mail.username=邮箱名称
    eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/
    spring.application.name=SEND_MAIL
    server.port=8082

*  创建一个controller 发送邮件的业务

package cn.et;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.mail.SimpleMailMessage;
    import org.springframework.mail.javamail.JavaMailSender;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    public class MailController {
        @Autowired
        private JavaMailSender jms;
            @GetMapping("/send")
            public String send(){
                SimpleMailMessage mailMessage = new SimpleMailMessage();
                //谁发的
                mailMessage.setFrom("邮箱地址");
                //发给谁
                mailMessage.setTo("邮箱地址");
                //标题
                mailMessage.setSubject("标题");
                //内容
                mailMessage.setText("内容");
                jms.send(mailMessage);
                return "1";
            }
    }

*  创建一个启动类 启动项目

package cn.et;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
    
    @SpringBootApplication
    @EnableEurekaClient
    public class Main { 
        public static void main(String[] args) {
            SpringApplication.run(Main.class, args);
        }
    }

*  最后 通过访问 配置注册中心时的请求路径 [http://localhost:8761/][http_localhost_8761] 查看注册的内容
