Semaphore.acquire()：最多n个运行，与Executors.newFixedThreadPool( 2 )作用相似
CyclicBarrier.await(): 加到n才开始
CountDownLatch.await(): 减到0才开始

被加锁的对象是共享数据，不是线程
1，put,get方法入口处设置断点，debug验证：可以同时有2个读线程，但最多只能有一个写线程
2，用ReentrantReadWriteLock实现线程安全的cache

JAXB（三）xsd 验证
- 博客分类：
- JAVA-JAXB
现在只有最简单的关联映射验证,
关键点：jaxbMarshaller.setSchema( sch );
还不会验证集合类型：List,Set,Map,以后再把JAXB（二）的例子加上，
/**

*/
@XmlRootElement
public class Address {
private String area;
