Return		 After widening the inc/dec arrows, the entire area of the arrows is not clickable.
This bug will only manifest itself if the left edge of the control label does not extend all the way to the left edge of the inc/dec arrows.

Workaround: If a label is not needed for the control, the user can add a label and then move it off screen programmatically using the ATTR_LABEL_LEFT and ATTR_LABEL_TOP attributes. The idea is to move it up and left far enough that it always is off screen, thereby ensuring the label always extends past the left edge of the inc/dec arrows.

    Storm中的日志级级别默认为INFO，并且，日志文件是根据worker号来进行区分的，这样，同一个log文件中的信息不一定是一个业务的，这样就会有以下两个需求出现： 1. 想要进行一些调试信息的输出 2. 调试信息或者业务日志信息想要输出到一些固定的文件中   不要怕，不要烦恼，其实Storm已经提供了这样的支持，可以通过自定义logback 下的 cluster.xml 来输

  • MySQL的btree索引和hash索引的区别 AILIKES 数据结构mysql算法
    Hash 索引结构的特殊性，其 检索效率非常高，索引的检索可以一次定位，不像B-Tree 索引需要从根节点到枝节点，最后才能访问到页节点这样多次的IO访问，所以 Hash 索引的查询效率要远高于 B-Tree 索引。     可能很多人又有疑问了，既然 Hash 索引的效率要比 B-Tree 高很多，为什么大家不都用 Hash 索引而还要使用 B-Tree 索引呢

  • [MongoDB学习笔记一]MongoDB主从复制 bit1129 mongodb

    在JavaWeb开发中，常使用绝对路径的方式来引入JavaScript和CSS文件，这样可以避免因为目录变动导致引入文件找不到的情况，常用的做法如下： 一、使用${pageContext.request.contextPath} 　　代码” ${pageContext.request.contextPath}”的作用是取出部署的应用程序名，这样不管如何部署，所用路径都是正确的。
  • Java定时任务调度：用ExecutorService取代Timer bylijinnan java
    《Java并发编程实战》一书提到的用ExecutorService取代Java Timer有几个理由，我认为其中最重要的理由是： 如果TimerTask抛出未检查的异常，Timer将会产生无法预料的行为。Timer线程并不捕获异常，所以 TimerTask抛出的未检查的异常会终止timer线程。这种情况下，Timer也不会再重新恢复线程的执行了;它错误的认为整个Timer都被取消了。此时，已经被

           简单工厂模式（Simple Factory Pattern）属于类的创新型模式，又叫静态工厂方法模式。是通过专门定义一个类来负责创建其他类的实例，被创建的实例通常都具有共同的父类。简单工厂模式是由一个工厂对象决定创建出哪一种产品类的实例。简单工厂模式是工厂模式家族中最简单实用的模式，可以理解为是不同工厂模式的一个特殊实现。
