Jquery converts the array to a string and then passes it to the server (after jquery converts the array to a string, the format is 1,2,3, speed, rewr)

define(function(require, exports, module) {

var Notify = require('common/bootstrap-notify');

module.exports = function($element) {

$element.on('click', '[data-role=batch-delete]', function() {

var $btn = $(this);
name = $btn.data('name');

var ids = [];
$element.find('[data-role=batch-item]:checked').each(function(){
ids.push(this.value);
});

if (ids.length == 0) {
Notify.danger(' Not selected ' + name);
return ;
}

if (!confirm(' This one will delete the selected one ' + ids.length + ' article ' + name + ' ? ')) {
return ;
}

$element.find('.btn').addClass('disabled');

Notify.info(' deleting ' + name + ' Just a moment, please. ', 60);
var values=ids.toString();
$.post($btn.data('url'), {ids:values}, function(){
window.location.reload();
});

});

};

});

Take the string from jquery, parse it into an array, and then convert the array into a list

@RequestMapping(value = "/delete", method = {RequestMethod.GET,RequestMethod.POST})
public ResponseEntity<AjaxPostResponse> delete(HttpServletRequest request) {
//List of private message ids to be deleted
String messageIds = ServletRequestUtils.getStringParameter(request, "ids", "");
String[] messageList=messageIds.toString().split(",");
List<String> messageIdList = Arrays.asList(messageList);//Convert an array to a list
logger.info("------------"+messageIds);
logger.info("------------"+messageList[0]);
try {
boolean opStatus = messageManager.delete(messageIdList);
logger.info(" Delete private message: opStatus={}", opStatus);
return this.okResponse(opStatus);
} catch (Exception e) {
logger.error(" An exception occurred while adding a private message , Cause: ", e);
return this.errorResponse(e.getMessage());
}
}
