## SpringBoot-Mail 发送邮箱（纯文本邮件+html邮件） ##

### 1、导入依赖 ###

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-mail</artifactId>
        <version>2.3.4.RELEASE</version>
    </dependency>
    
    
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-thymeleaf</artifactId>
    </dependency>

### 2、在application.properties配置JavaMailSender Bean ###

# JavaMailSender 配置
    spring.mail.host=smtp.163.com
    spring.mail.username=xxx@163.com # 发送邮件的邮箱
    spring.mail.password=xxx # 启用smtp协议的秘钥
    spring.mail.port=465
    spring.mail.default-encoding=utf-8
    spring.mail.properties.mail.smtp.auth=true
    spring.mail.properties.mail.smtp.starttls.enable=true
    spring.mail.properties.mail.smtp.starttls.required=true
    # SSL 配置
    spring.mail.protocol=smtp
    spring.mail.properties.mail.smtp.ssl.enable=true
    spring.mail.properties.mail.smtp.socketFactory.port=465
    spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory

### 2、发送邮箱 ###

/**
     *mail 客户端
     */
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.mail.javamail.JavaMailSender;
    import org.springframework.mail.javamail.MimeMessageHelper;
    import org.springframework.stereotype.Component;
    
    import javax.mail.MessagingException;
    import javax.mail.internet.MimeMessage;
    
    @Component
    public class MailClient {
        
    
        private static final Logger logger = LoggerFactory.getLogger(MailClient.class);
    
        @Autowired
        private JavaMailSender mailSender;
    
        @Value("${spring.mail.username}")
        private String from;
    
        public void sendMail(String to, String subject, String content) {
        
            try {
        
                MimeMessage message = mailSender.createMimeMessage();
                MimeMessageHelper helper = new MimeMessageHelper(message);
                helper.setFrom(from);
                helper.setTo(to);
                helper.setSubject(subject);
                helper.setText(content, true);
                mailSender.send(helper.getMimeMessage());
            } catch (MessagingException e) {
        
                logger.error("发送邮件失败:" + e.getMessage());
            }
        }
    }

### 3、测试邮箱是否发送成功 ###

import com.example.email.Ch10SpringbootEmailApplication;
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.test.context.SpringBootTest;
    import org.springframework.test.context.ContextConfiguration;
    import org.springframework.test.context.junit4.SpringRunner;
    import org.thymeleaf.TemplateEngine;
    import org.thymeleaf.context.Context;
    
    @RunWith(SpringRunner.class)
    @SpringBootTest
    @ContextConfiguration(classes = Ch10SpringbootEmailApplication.class)
    public class MailClientTest {
        
        @Autowired
        private MailClient mailClient;
    
        @Autowired
        private TemplateEngine templateEngine;
    
        // 1、发送普通纯文本邮件
        @Test
        public void testTextMail() {
        
            // 填写收件人邮箱、邮件title、邮件文本内容
            mailClient.sendMail("xx@qq.com", "TEST", "Hello java spring mail"); 
        }
    
        // 2、发送html页面邮件
        @Test
        public void testHtmlMail() {
         
            Context context = new Context();
            context.setVariable("username", "spring mail test");
    
            String content = templateEngine.process("/mail/demo", context);
            System.out.println(content);
    
            mailClient.sendMail("2807975464@qq.com", "TEXT", content); 
        }
    }

<!DOCTYPE html>
    <html lang="en" xmlns:th="http://www.thymeleaf.com">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
    </head>
    <body>
    
    <p>欢迎你,<span style="color: red;" th:text="${username}"></span></p>
    </body>
    </html>
