我尝试使用aspectj maven插件与aspectj编译器编译项目,然后我尝试将类打包成"war"文件.不幸的是,它不适用于以下配置(pom.xml):

之后mvn clean install我看到下列情况除外: …

我尝试在liferay 6.1.1上部署我的应用程序并得到此错误(当我在6.0.6上测试此应用程序时一切正常).这是什么意思？

引起:com.liferay.portal.kernel.xml.DocumentException:文档第1行出错:XML声明中"version"后面的值必须是带引号的字符串.嵌套异常:XML声明中"version"后面的值必须是带引号的字符串.

我Stanford NLP在分类工具中用于字符串标记化.我想唯一有意义的话,但我得到的非字标记(如---,>,.等),而不是重要的话像am,is,to(停用词).有人知道解决这个问题的方法吗？

我尝试构建持久消息队列,每条消息有一些延迟.在Java代码中,它看起来像这样:

    ConnectionFactory factory = new ConnectionFactory();
    factory.setHost("localhost");
    Connection connection = factory.newConnection();
    Channel channel = connection.createChannel();

    channel.exchangeDeclare("WorkExchange", "direct");
    channel.queueDeclare("WorkQueue", true, false, false, null);
    channel.queueBind("WorkQueue", "WorkExchange", "");

    Map<String, Object> args = new HashMap<>();
    args.put("x-dead-letter-exchange", "WorkExchange");

    channel.exchangeDeclare("RetryExchange", "direct");
    channel.queueDeclare("RetryQueue", true, false, false, args);
    channel.queueBind("RetryQueue", "RetryExchange", "");

    channel.confirmSelect();
    BasicProperties properties = new BasicProperties();
    properties.setDeliveryMode(2);
    properties.setExpiration("120000");
    channel.basicPublish("RetryExchange", "", properties, "Hello world!".getBytes());
    channel.waitForConfirmsOrDie();
    connection.close();

但是,我有一些持久性问题.当我停止服务器时,等待一段时间再次启动它,必须移动到WorkQueue的消息才会消失.我做错了什么？或者它是设计的？

我正在使用Spark Streaming updateStateByKey()和mapWithState()函数,但我不清楚哪里保存了状态.状态是否保存在HDFS上？或者它是内存存储？如何保证容错？

我正在尝试实现以下场景：

1. clone()带CLONE_NEWNS标志的主进程（这意味着新的挂载命名空间）
2. mount() 子进程中的新文件系统
3. 子进程完成并且所有在这个进程文件系统中创建的都被卸载

但它并没有像我预期的那样工作，我仍然在主进程中看到挂载的文件系统。我究竟做错了什么？
