我在我的 camunda 环境中有这个类（我在 camunda 建模器中使用这个类作为服务任务）：

public class SendMails implements JavaDelegate{

    String  text,from,password;
    Object jsonObject1=new JSONObject();
 public static void send( final String from, final String password,String to,String sub,String msg){  
     Properties props = new Properties();    
     props.put("mail.smtp.host", "smtp.gmail.com");    
     props.put("mail.smtp.socketFactory.port", "465");    
     props.put("mail.smtp.socketFactory.class",    
               "javax.net.ssl.SSLSocketFactory");    
     props.put("mail.smtp.auth", "true");    
     props.put("mail.smtp.port", "465");    
     //get Session   
     Session session = Session.getDefaultInstance(props,    
      new javax.mail.Authenticator() {    
      protected PasswordAuthentication getPasswordAuthentication() {    
      return new PasswordAuthentication(from,password);  
      }    
     });    
     //compose message    
     try {    
      MimeMessage message = new MimeMessage(session);    
      message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));    
      message.setSubject(sub);    
      message.setText(msg);    
      //send message  
      Transport.send(message);    
      System.out.println("message sent successfully");    
     } catch (MessagingException e) {throw new RuntimeException(e);}    

}  

    public void execute(DelegateExecution execution) throws Exception {

        text = execution.getVariable("selectedDocuments").toString();
        send("demo@camunda.org","xxxxx","test@gmail.com","hello javatpoint","How r u?");  

        }
    }

这是我的POM：

<dependencies>  
 <dependency>
      <groupId>org.camunda.bpm</groupId>
      <artifactId>camunda-engine</artifactId>
      <scope>provided</scope>
    </dependency>

    <artifactId>javaee-api</artifactId>
    <version>8.0</version>
    <scope>provided</scope>
</dependency>

    </dependencies>

但是当我尝试发送消息时，我收到了这样的错误：

引起：com.sun.mail.util.MailConnectException：无法连接到主机，端口：smtp.gmail.com，465；超时-1；嵌套异常是：java.net.ConnectException：连接超时：在 com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java) 处连接 com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:2100) :699) 在 javax.mail.Service.connect(Service.java:388) 在 javax.mail.Service.connect(Service.java:246) 在 javax.mail.Service.connect(Service.java:195) 在 javax .mail.Transport.send0(Transport.java:254) 在 javax.mail.Transport.send(Transport.java:124) 在 ge.psda.camunda.sendMails.SendMails.send(SendMails.java:40) ...还有 208 个

PS我在我的邮件中启用了不太安全的功能，但这不能帮助我我应该改变什么才能发送邮件？

您必须为发件人提供凭据。您已为 gmail 配置（属性）它。实际上，您已经为发送电子邮件的 smtp 服务器配置了属性。

以及您需要的依赖项：

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

    <dependency>
        <groupId>javax.activation</groupId>
        <artifactId>activation</artifactId>
        <version>1.1.1</version>
    </dependency>

</dependencies>
