推荐答案
我在机器上尝试过两个错误
I have tried this on my machine two errors I got.
首先，您拼错了属性这里
roperties.setProperty("mail.password", "Paasword");
其次，访问被拒绝为 file.txt 。
Second, Access is denied error for file.txt. I managed to give a path to it and it worked.
结果：显示我的邮件已成功发送。
<%@ page import="java.io.*,java.util.*,javax.mail.*"%>
<%@ page import="javax.mail.internet.*,javax.activation.*"%>
<%@ page import="javax.servlet.http.*,javax.servlet.*" %>

properties.setProperty("mail.password", "Paasword");
//String to = request.getParameter("to");

String subject = request.getParameter("subject");
String messageText = request.getParameter("body");
