在我的Xpages应用程序中，我想从Java发送（HTML）电子邮件。我在OpenNTF上找到了这段不错的EmailBean代码作为片段：
我将代码转换为通用的Email类，而不将其用作托管bean。
我还想以不同的方式使用代码：与其使用从XPage创建的DominoDocument，不如直接使用anotehr java类中的类。但是我面临以下问题：
代码需要一个DominoDocument和该文档上的字段作为电子邮件内容。
所以在我的sendMail方法中，我尝试过：
Database db = DominoUtils.getCurrentDatabase();
DominoDocument fakeMail = (DominoDocument) db.createDocument();
但是从未创建此DominoDocument（代码在此处中断）
Database db = DominoUtils.getCurrentDatabase();
Document fakeMail = db.createDocument();
工作正常，但
Email email = new Email();
email.setDocument(fakeMail);
说明应该使用DominoDocument而不排除Document。
我接下来的想法是在尝试尝试跳过中间文档的地方
email.setBodyHTML("Hello World");
我在控制台中收到以下消息：
[1728：0016-08FC] 2018-09-15 16:18:14 HTTP JVM：不允许使用方法setBodyHTML（string）
有没有人可以指导我如何更改此电子邮件类别，因此我不需要DominoDocument？实际上，我根本不需要任何文档。如果setBodyHTML（）可以工作，我可以自己设置电子邮件对象的属性。

在Domino中发送邮件的方法是通过文档。最简单的方法是在mail.box中创建一个路由器数据库。在那里您只能保存一次，保存将发送消息。
但是... 在没有您提到的任何转换工作的情况下，托尼的课程应该可以正常工作。托管bean只是一个简单的Java类，具有无参数的构造函数和get / set方法。
因此，从其他Java代码中，您应该只能使用此代码：
EmailBean email = new EmailBean();
email.set(...) // to, body, subject etc
email.send();
您需要更改的内容：
get/setHTMLBody的工作方式类似于HTMLfooter->存储在本地变量中get/setTextBody方法和局部变量send()方法中，而不是从文档中提取，请使用局部变量对您有用吗？

为什么不精简该电子邮件课程？

然后在您的其他班级添加如下内容：
private void sendMail(String msg){
try{
Email email = new Email();
email.setSendTo("yourname@acme.org");
email.setSubject("Mail from Java");
email.setSenderEmail("no-rely@acme.org");
email.setSenderName("No-reply");
email.setBodyHTML(msg);
email.setBannerHTML("<p>Hi " + email.getSendTo() + ",</p>");
email.setFooterHTML("<p><b>Kind regards,</b><br/>" + email.getSenderName() + "<br/>0044 1234 5678</p>");
email.send();
} catch (Exception e) {
OpenLogUtil.logError(e);
}
}
不再读取DominoDocument。我添加了一个字段：private String bodyHTML。我已将setBodyHTML方法更改为标准的setter方法。
我精简了send（）方法，主要是这一部分：
MIMEEntity emailRootChild = emailRoot.createChildEntity();
if (null != emailRootChild) {
final String boundary = System.currentTimeMillis() + "-" + "ABC";
emailHeader = emailRootChild.createHeader("Content-Type");
emailHeader.setHeaderVal("multipart/alternative; boundary=\"" + boundary + "\"");
MIMEEntity emailChild = emailRootChild.createChildEntity();
if (null != emailChild) {
Stream stream = session.createStream();
emailChild = emailRootChild.createChildEntity();
stream = session.createStream();
stream.writeText(this.getHTML());
emailChild.setContentFromText(stream, "text/html; charset=\"UTF-8\"", MIMEEntity.ENC_NONE);
stream.close();
stream.recycle();
stream = null;
}
}
最后，您只会得到基本的HTML电子邮件，没有图像或附件。我不确定这是否符合您的需求？

我对OpenNTF Domino API进行了相同的转换过程。它具有DominoEmail类，请参见https://stash.openntf.org/projects/ODA/repos/dominoapi/browse/domino/core/src/org/openntf/domino/email?at=30690a2ddccb024bae6fcf37cbdd42860c7e5ba6。这适用于基本的电子邮件，包括我相信的HTML。但这还不足以支持例如附件。如果有特殊需要，我很高兴有人能够完成这方面的工作，并乐意提供建议以帮助您取得进步。
