用java发送邮件

1.需要的maven依赖：

<dependency>    <groupId>com.sun.mail</groupId>    <artifactId>javax.mail</artifactId>    <version>1.5.5</version></dependency><dependency>    <groupId>org.springframework</groupId>    <artifactId>spring</artifactId>    <version>2.5.6.SEC03</version></dependency>

2.代码：

public class TestMain {    @Test    public void  testMail(){        JavaMailSenderImpl theMail = new JavaMailSenderImpl ();        theMail.setDefaultEncoding("UTF-8");        theMail.setUsername("*******@**.com");//发送邮箱        theMail.setPassword("*******");//开启smtp服务的密码串        theMail.setHost("smtp.163.com");        theMail.setPort(25);//常规邮箱有两种，不加密的走25号端口，加密的走465端口        Properties javaMailProperties=new Properties();        javaMailProperties.put("mail.smtp.auth", "true");        javaMailProperties.put("mail.smtp.timeout", 0);        theMail.setJavaMailProperties(javaMailProperties);        MimeMessage mailMessage =                theMail.createMimeMessage();        MimeMessageHelper messageHelper;        try {            messageHelper = new MimeMessageHelper(mailMessage, true);        messageHelper.setFrom(theMail.getUsername());        messageHelper.setTo("*******@**.com");//收件箱        messageHelper.setSubject("邮件测试");//主题        messageHelper.setText("< a href= 'www.baidu.com'>进入百度</ a>",true);//邮件内容        theMail.send(mailMessage);        } catch (Exception e) {            e.printStackTrace();        }        System.out.println("邮件发送成功...");    }}
