我只是尝试使用JAVA BEANS（JSP）发送确认电子邮件，但我收到了这个恼人的错误：

无法连接到主机＆＃34; smtp.gmail.com＆＃34;，端口：465，响应：-1

public String getMessage() {
    return message;
}

/**

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

我在这个页面中调用了MailServiceBean类：

<%@page import="prueba.MailServiceBean"%>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%
   MailServiceBean mail = new MailServiceBean();
   mail.setToEmail("toMail@hotmail.com");
   mail.setSubject("Dumb Subject");
   mail.setMessage("Testing mail");
   mail.sendConfirmationMail();
   response.sendRedirect("pagina.html");
%>
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
        <h1>Hello World!</h1>
    </body>
</html>

我该如何纠正？我必须承认代码工作了几次，现在它没用了。：（

Answer 1

好的，最终找到了解决方案......只需添加此属性：

properties.put("mail.smtp.ssl.enable", "true");

就是这样。
