java - 我正在努力在远程服务器中发送电子邮件，但它在本地工作，在远程服务器中抛出 'AuthenticationFailedException'

Question

这是我的配置文件。同时，我还在接收方电子邮件中启用了“不太安全的应用程序是真实的”。我正在使用 587 smpt.gmail.com 端口，因为我仅使用 HTTP，而不是 HTTPS。在本地服务器中，即使接收者邮件也有两步验证，也很高兴邮件正在发送，但来到远程服务器时，我收到了 AuthenticationFailedException 。我也尝试了很多代码更改，但仍然无法重新解决这个问题。我不知道问题出在哪里。

Config.xml:

<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
    <property name="host" value="smtp.gmail.com"/>
    <property name="port" value="587"/>
    <property name="username" value="abc@gmail.com"/>
    <property name="password" value="xxxxxx"/>
    <property name="javaMailProperties">
        <props>
            <prop key="mail.transport.protocol">smtp</prop>
            <prop key="mail.smtp.auth">true</prop>
            <prop key="mail.smtp.starttls.enable">true</prop>
        </props>
    </property>
</bean>

<bean id="emailSession" class="javax.mail.Session" factory-method="getInstance">

<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">

电子邮件服务:

import javax.mail.Message;
import javax.mail.internet.MimeMessage;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Service;

@Service
public class EmailService {
    @Autowired
    private  JavaMailSender mailSender;

    public void sendEmail(String from,String to,String subject,String message){
        try {
            MimeMessage mimeMessage=mailSender.createMimeMessage(); 
            mimeMessage.addRecipients(Message.RecipientType.TO, to);
            mimeMessage.setSubject(subject);
            mimeMessage.setContent(message, "text/html");   
            mailSender.send(mimeMessage);
        }
        catch(Exception e) {
            e.printStackTrace();
        }

    }

}

<bean id="emailAuthenticator" class="com.user.service.EmailSMTPAuthenticator">
    <property name="password" value="{Authorization code}"></property>
</bean>
