多线程下并发同步机制

http://pluto418.iteye.com/blog/1179497
1. 前言 JDK提供的并发包，除了上一篇提到的用于集合外，还有线程的调度、协作、调度等等功能。上篇提到过，线程之间除了竞争关系，还有协作关系。在高并发环境下有效利用Java并发包解决线程之间协作的特殊场景。在并行计算，尤其是多线程计算的结果集合并的时候都需要用到这些并发同步器。还有一种使用场景，就是跨越多台机器（实机）的多线程进行并行运算，需要将多台机器进行结果集的汇总，合并。其原理核心也是使用这些并发协作包。 2. FutureTask FutureTask是进行并行结果集合并的类，此类是Future ...

EHcache

http://blog.csdn.net/liuzhenwen/article/details/3983952
需要使用Spring来实现一个Cache简单的解决方案，具体需求如下：使用任意一个现有开源Cache Framework，要求可以Cache系统中Service或则DAO层的get/find等方法返回结果，如果数据更新（使用Create/update/delete方法），则刷新cache中相应的内容。 根据需求，计划使用Spring AOP + ehCache来实现这个功能，采用ehCache原因之一是Spring提供了ehCache的支持，至于为何仅仅支持ehCache而不 ...
数据库join操作的算法
- 博客分类：
- Database
数据库join操作的算法：
1 嵌套循环连接 nested loop join O(n^2)，两层循环
2 块嵌套循环连接 nested block loop join O(n^2),但是省了很多IO时间， 两层循环。
3 索引嵌套循环 O(nlgn), 外层表scan，内层表用index来查
4 归并连接 merge join O(n)，但是需要连接的col事先要有序。

关于互斥锁：
所谓互斥锁, 指的是一次最多只能有一个线程持有的锁. 在jdk1.5之前, 我们通常使用synchronized机制控制多个线程对共享资源的访问. 而现在, Lock提供了比synchronized机制更广泛的锁定操作, Lock和synchronized机制的主要区别:
synchronized机制提供了对与每个对象相关的隐式监视器锁的访问, 并强制所有锁获取和释放均要出现在一个块结构中, 当获取了多个锁时, 它们必须以相反的顺序释放. synchronized机制对锁的释放是隐式的, 只要线程运 ...
