代码都写好了报错如下：

Exception in thread "main" com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.57 SMTP; Client was not authenticated to send anonymous mail during MAIL FROM

后来检查发现依赖的包不对，错误的包为

<dependency>
    	<groupId>javax.mail</groupId>
    	<artifactId>mail</artifactId>
    	<version>1.4</version>
    </dependency>

改为下面就成功了

<dependency>
    	<groupId>javax.mail</groupId>
    	<artifactId>mail</artifactId>
    	<version>1.4.7</version>
    </dependency>

代码参考

import java.util.Properties;
    import javax.mail.Message;
    import javax.mail.Session;
    import javax.mail.Transport;
    import javax.mail.internet.InternetAddress;
    import javax.mail.internet.MimeMessage;
    
    public class Test {
    
    	public static void main(String[] args) throws Exception {
            Properties props = new Properties();
            props.setProperty("mail.smtp.auth", "true");
            props.setProperty("mail.transport.protocol", "smtp");
            props.put("mail.smtp.host","mail.x.com");
            props.setProperty("mail.smtp.port","587");
            Session session = Session.getInstance(props);
            session.setDebug(true);
            
            Message msg = new MimeMessage(session);
            msg.setSubject("这是一个测试程序");
            msg.setText("你好!这是一个测试程序");
            msg.setFrom(new InternetAddress("xx@xx.com"));
            msg.setRecipient(Message.RecipientType.TO,new InternetAddress("xx.com"));
            msg.saveChanges();
    
            Transport transport = session.getTransport();
            transport.connect("username","password");      
            transport.sendMessage(msg, msg.getAllRecipients());
            
            System.out.println("邮件发送成功");
            transport.close();
        }
    
    
    }
