java - 使用 spring mail 将邮件发送到 gmail 帐户的问题

Question

我在使用 spring mail 向 gmail 帐户发送邮件时遇到了问题。 我引用了 stackoverflow 中的大部分帖子并尝试了这些帖子。但没有运气。仍然坚持下去。请建议我的代码中还缺少什么。

Windows -8: Java 7

EmailServiceImpl.java:

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import com.test.mail.data.EmailData;

public class EmailServiceImpl {                                    
private JavaMailSender mailSender;

public JavaMailSender getMailSender() {
return mailSender;
}

public void setMailSender(JavaMailSender mailSender) {
this.mailSender = mailSender;
}
    public void sendMail(EmailData emailData) {
    MimeMessage message = mailSender.createMimeMessage();
    MimeMessageHelper helper = new MimeMessageHelper(message);
    try {
        helper.setFrom(emailData.getFrom());
        helper.setTo(emailData.getTo());
        helper.setSubject(emailData.getSubject());
        helper.setText(emailData.getBody());
    } catch (MessagingException e) {
        e.printStackTrace();
    }
    mailSender.send(message);
}
}

应用程序上下文.xml

            <bean id="emailSvcImpl"
                            class="com.test.mail.services.impl.EmailServiceImpl">

            </bean>  -->

Maven 依赖项:

            <dependency>
                       <groupId>org.springframework</groupId>
                       <artifactId>spring-context-support</artifactId>
                       <version>3.2.11.RELEASE</version>
             </dependency>

                 <version>1.5.2</version>
            </dependency>

cmd提示:用'ping smtp.gmail.com'命令ping ，能得到回复，没有数据丢失。

异常:

   org.apache.cxf.interceptor.Fault: Mail server connection failed; nested exception is com.sun.mail.util.MailConnectException: Couldn't connect to host,   port: smtp.gmail.com, 465; timeout -1;
nested exception is:
           java.net.ConnectException: Connection refused: connect. Failed messages: com.sun.mail.util.MailConnectException: Couldn't connect to host, port: smtp.gmail.com, 465; timeout -1;
nested exception is:

尝试使用 SSL 和 TLS 发送邮件，但端口号不同但​​同样异常

Google 已更改政策，您需要允许应用程序访问您的帐户。

我昨天遇到了一个问题，并通过 google.com 收到了这封电子邮件

您可以切换到 Gmail 等 Google 开发的应用程序来访问您的帐户(推荐)或在 https://www.google.com/settings/security/lesssecureapps 更改您的设置这样您的帐户就不再受现代安全标准的保护。

完成所有操作后，您可以验证属性，这就是我使用的并且它在我这边工作得很好

 Properties props = new Properties();
 props.put("mail.smtp.host", "smtp.gmail.com"); //SMTP Host
 props.put("mail.smtp.socketFactory.port", "465"); //SSL Port
 props.put("mail.smtp.socketFactory.class",
 "javax.net.ssl.SSLSocketFactory"); //SSL Factory Class
 props.put("mail.smtp.auth", "true"); //Enabling SMTP Authentication
 props.put("mail.smtp.port", "465"); //SMTP Port

希望您使用的是正确的值。
