java.lang.IllegalArgumentException：'original'message参数不能为null [英] java.lang.IllegalArgumentException: The 'original' message argument cannot be null

问题描述

我正在尝试使用Spring发送电子邮件。看看我的代码：

  public class Provider {
 
 private MailSender mailSender; 
私人SimpleMailMessage消息; 
 
 public void setMailSender（MailSender mailSender）{
 this.mailSender = mailSender; 
} 
 
 public void setMessage（SimpleMailMessage message）{
 this.message = message; 
} 
 
 public static String getTemplateName（）{
 returnmainLayout / layout.jsp; 
} 
 
 
 public void placeOrder（）{
 
 // ... *做业务计算.... 
 / / ... *呼叫协作者持久订单
 
 //创建一个线程安全的沙箱消息
 SimpleMailMessage msg = new SimpleMailMessage（this.message）; 
 msg.setTo（[e-mail]）; 
 msg.setText（Hello）; 
 try {
 mailSender.send（msg）; 
} catch（MailException ex）{
 //登录并执行
 System.err.println（ex.getMessage（））; 
} 
} 
 
} 
  

不知道为什么它不工作。我不知道怎么了我添加了所有的类似邮件。

解决方案

  SimpleMailMessage msg = new SimpleMailMessage（this.message ）; 
  

我认为 this.message 为null。您应该首先初始化它。

I'm trying to send email using Spring. Look at my code:

public class Provider {

    private MailSender mailSender;
    private SimpleMailMessage message;

    public void setMailSender(MailSender mailSender) {
        this.mailSender = mailSender;
    }

    public void setMessage(SimpleMailMessage message) {
        this.message = message;
    }

    public static String getTemplateName() {
        return "mainLayout/layout.jsp";
    }


    public void placeOrder() {

        // ... * Do the business calculations....
        // ... * Call the collaborators to persist the order

        // Create a thread safe "sandbox" of the message
        SimpleMailMessage msg = new SimpleMailMessage(this.message);
        msg.setTo("[e-mail]");
        msg.setText("Hello");
        try {
            mailSender.send(msg);
        } catch (MailException ex) {
            // log it and go on
            System.err.println(ex.getMessage());
        }
    }

}

Don't know why it's not working. I have no idea what's wrong. I added all depencies like mail.

解决方案

SimpleMailMessage msg = new SimpleMailMessage(this.message);

I think this.message is null.You should initialize it first.
