在html中定义个按钮

             <span class="btn btn-success k-grid-save-changes" data-bind="click:save" style="float:left;margin-right:5px;"><@spring.message "ora20796.sendEmail"/></span>

html添加事件函数

<script type="text/javascript">
    var viewModel = Hap.createGridViewModel("#grid",{
        sendEmail:function () {
            $.ajax({
                url: '${base.contextPath}/wht/ora/20796/student/send/email',
                type: 'POST',
                dataType: "json",
                contentType: "application/json",
                success: function (result) {
                    if(result.success){
                        kendo.ui.showInfoDialog({
                            title: $l('hap.tip.info'),
                            message: $l("hap.success")
                        });
                        viewModel.query();
                    } else {
                        kendo.ui.showErrorDialog({
                            title: $l('hap.error'),
                            message : result.message
                        });
                    }
                }
            });
        }
    });
</script>

接口类：

package wht.ora20796.service;

import com.hand.hap.core.IRequest;
import com.hand.hap.core.ProxySelf;
import com.hand.hap.system.dto.ResponseData;
import com.hand.hap.system.service.IBaseService;
import org.springframework.beans.factory.annotation.Autowired;

import java.util.List;

public interface IOra20796DemoService extends IBaseService<Ora20796Demo>, ProxySelf<IOra20796DemoService>{

        /**
         *

        /**
         * 邮箱发送
         */
        ResponseData sendEmail(IRequest iRequest)throws Exception;

}

实现类

   @Autowired
    private IMessageService messageService;
/**
     * 邮箱发送
     *
     * @param iRequest
     * @return
     * @throws Exception
     */
    @Override
    public ResponseData sendEmail(IRequest request) throws Exception {
        ResponseData responseData = new ResponseData();
        HashMap<String, Object> templateData = new HashMap<String, Object>();

        templateData.put("EMAIL_CONTENT", "This is a test email from Demo page");
        templateData.put("SENDER", request.getUserName());
        //收件人,可以有多人
        ArrayList<MessageReceiver> receivers = new ArrayList<>();

        MessageReceiver messageReceiver = new MessageReceiver();
        messageReceiver.setMessageAddress("shizhou.cui@hand-china.com");
        messageReceiver.setMessageType(ReceiverTypeEnum.NORMAL.getCode());
        receivers.add(messageReceiver);

        //messageService.sendMessage(request, "ACT_EMAIL_NOTIFIER", templateData, receivers, (List<Long>) null);
        messageService.sendMessage(request, "ORA_20796_DEMO", templateData, receivers, (List<Long>) null);

        return responseData;
    }

控制类：

    /**
     * 邮箱发送
     */
    @RequestMapping(value = "/hap/demo/send/email")
    @ResponseBody
    public ResponseData sendEmail(HttpServletRequest request) {
        IRequest iRequest = createRequestContext(request);
        ResponseData responseData = new ResponseData();
        try {
            responseData = service.sendEmail(iRequest);
        } catch (Exception e) {
            responseData.setSuccess(false);
            responseData.setMessage(e.getMessage());
        }
        return responseData;
    }

Failed to close server connection after message sending; nested exception is javax.mail.MessagingException: Exception reading response (java.net.SocketTimeoutException: Read timed out)
