springboot对JMS提供了很好的支持，对其做了起步依赖。
构架工程
创建一个springboot工程，在其pom文件加入：
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-mail</artifactId> </dependency>
添加配置
spring.mail.host=smtp.163.com spring.mail.username=miles02@163.com spring.mail.password= spring.mail.port=25 spring.mail.protocol=smtp spring.mail.default-encoding=UTF-8
在password 中填写自己的邮箱密码。
测试发邮件
测试代码清单如下：
package com.forezp; 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.core.io.FileSystemResource; import org.springframework.mail.SimpleMailMessage; import org.springframework.mail.javamail.JavaMailSenderImpl; import org.springframework.mail.javamail.MimeMessageHelper; import org.springframework.test.context.junit4.SpringRunner; import javax.mail.internet.MimeMessage; import java.io.File; @RunWith(SpringRunner.class) @SpringBootTest public class SpringbootJmsApplicationTests { @Test public void contextLoads() { } @Autowired private JavaMailSenderImpl mailSender; /** * 发送包含简单文本的邮件 */ @Test public void sendTxtMail() { SimpleMailMessage simpleMailMessage = new SimpleMailMessage(); // 设置收件人，寄件人 simpleMailMessage.setTo(new String[] {"miles02@163.com"}); simpleMailMessage.setFrom("miles02@163.com"); simpleMailMessage.setSubject("Spring Boot Mail 邮件测试【文本】"); simpleMailMessage.setText("这里是一段简单文本。"); // 发送邮件 mailSender.send(simpleMailMessage); System.out.println("邮件已发送"); } /** * 发送包含HTML文本的邮件 * @throws Exception */ @Test public void sendHtmlMail() throws Exception { MimeMessage mimeMessage = mailSender.createMimeMessage(); MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage); mimeMessageHelper.setTo("miles02@163.com"); mimeMessageHelper.setFrom("miles02@163.com"); mimeMessageHelper.setSubject("Spring Boot Mail 邮件测试【HTML】"); StringBuilder sb = new StringBuilder(); sb.append("<html><head></head>"); sb.append("<body><h1>spring 邮件测试</h1><p>hello!this is spring mail test。</p></body>"); sb.append("</html>"); // 启用html mimeMessageHelper.setText(sb.toString(), true); // 发送邮件 mailSender.send(mimeMessage); System.out.println("邮件已发送"); } /** * 发送包含内嵌图片的邮件 * @throws Exception */ @Test public void sendAttachedImageMail() throws Exception { MimeMessage mimeMessage = mailSender.createMimeMessage(); // multipart模式 MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage, true); mimeMessageHelper.setTo("miles02@163.com"); mimeMessageHelper.setFrom("miles02@163.com"); mimeMessageHelper.setSubject("Spring Boot Mail 邮件测试【图片】"); StringBuilder sb = new StringBuilder(); sb.append("<html><head></head>"); sb.append("<body><h1>spring 邮件测试</h1><p>hello!this is spring mail test。</p>"); // cid为固定写法，imageId指定一个标识 sb.append("<img src=\"cid:imageId\"/></body>"); sb.append("</html>"); // 启用html mimeMessageHelper.setText(sb.toString(), true); // 设置imageId FileSystemResource img = new FileSystemResource(new File("E:/1.jpg")); mimeMessageHelper.addInline("imageId", img); // 发送邮件 mailSender.send(mimeMessage); System.out.println("邮件已发送"); } /** * 发送包含附件的邮件 * @throws Exception */ @Test public void sendAttendedFileMail() throws Exception { MimeMessage mimeMessage = mailSender.createMimeMessage(); // multipart模式 MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage, true, "utf-8"); mimeMessageHelper.setTo("miles02@163.com"); mimeMessageHelper.setFrom("miles02@163.com"); mimeMessageHelper.setSubject("Spring Boot Mail 邮件测试【附件】"); StringBuilder sb = new StringBuilder(); sb.append("<html><head></head>"); sb.append("<body><h1>spring 邮件测试</h1><p>hello!this is spring mail test。</p></body>"); sb.append("</html>"); // 启用html mimeMessageHelper.setText(sb.toString(), true); // 设置附件 FileSystemResource img = new FileSystemResource(new File("E:/1.jpg")); mimeMessageHelper.addAttachment("image.jpg", img); // 发送邮件 mailSender.send(mimeMessage); System.out.println("邮件已发送"); } }测试已全部通过，没有坑。
