使用javamail发送邮件时出错

这是我发送邮件的代码

阅读中的所有答案

您还可以修改代码，以便在发送到时设置上下文类加载器：

因此，我刚刚在这里测试了您的代码，它与以下两个邮件工件com.sun.mail:javax.mail:1.5.2和javax.mail:javax.mail api:1.5.2完美地配合使用，始终保持邮件工件的api部分和实现部分同步。因此，要么将mailapi-1.5.2更改为mailapi-1.4.7，要么将javamail impl从1.4.7更新为1.5.2。

您能为我们提供更多的实现和项目设置吗。从stacktrace中很难看到发生了什么。我已经添加了更多的细节。您能提供帮助吗？很明显，您的com.sun.mail.smtp.SMTPTransport类的版本不匹配。你能说一下，你使用的是哪个版本的mail.jar吗？我使用的是javamail-1.4.7.Ok，这里是javamail 1.5.2，工作没有问题。。。您是否可以查看您的类路径并验证没有其他邮件实现，以便消除版本冲突。您不需要com.sun.mail:javax.mail和javax.mail:javax.mail-api。前者包含后者的所有内容。是的，先生。我把那个罐子拿走了。。谢谢你救了我的命。谢谢 DEBUG: JavaMail version 1.5.2 DEBUG: successfully loaded
