java - 在控制器 Java 中成功操作后，如何在屏幕上显示成功消息？

Question

单击按钮时，我在控制器中有一个发送电子邮件的操作。我想在发送所有电子邮件时向用户显示一条消息以通知。

@Action(value = "sendRequest", results = { @Result(name = SUCCESS, location = "mail.jsp"),
            @Result(name = ERROR, location = "mail.jsp")})
public class MailController {

    public String sendMails() {

        //code where the mails are sending to users

        return SUCCESS;
    }
}

<div>
    <span class="button"><input type="button"
    id="_mailAll" class="buttonMails" value="Send" /></span>
</div>

$('#_mailAll').click(function () {
        var form = $('#_dashboardForm') ;
        form.attr('action', 'sendEmails.action');
        form.submit();
});
