java WebService
In recent years, web services have emerged as a popular technology for remote method calls. Technically, a web service has two components:
A service that can be accessed with the SOAP transport protocol
A description of the service in the WSDL format
SOAP is an XML protocol for invoking remote methods, similar to the protocol that RMI uses for the communication between clients and servers. Just as you can program RMI applications without knowing anything about the details of the RMI protocol, you don't really need to know any details about SOAP to call a web service.
WSDL is an interface description language. It too is based on XML. A WSDL document describes the interface of a web service: the methods that can be called, and their parameter and return types. In this section, we generate a WSDL document from a service implemented in Java. This document contains all the information that a client program needs to invoke the service, whether it is written in Java or another programming language.

这个算法简单,而且效率高,每次可以操作8个字节的数据,加密解密的KEY为16字节,即包含4个int数据的int型数组,加密轮数应为8的倍数,一般比较常用的轮数为64,32,16,推荐用64轮.

Read-Write Lock Pattern的参与者：
1. Reader（读取者）参与者
Reader参与者会对SharedResource参与者进行read。
2. Writer（写入者）参与者
Writer参与者会对SharedResource参与者进行write。
3. SharedResource（共享资源）参与者
