本书讲述的Struts、Hibernate、Spring无论在已有项目的选用比例，还是在开发人员的认知度上，都是最有影响力和号召力的，Struts+Hibernate+Spring已经成为轻量级开发J2EE的标准配置，被称为SHS经典组合，这也是目前Java程序员必须掌握的技能。本书是一本由小实例组合成的实践书，每个案例读者都可以亲自实践。(Book tells Struts, Hibernate, Spring, whether in the selection of the ratio of existing projects, or in the awareness of developers, are the most influential and charismatic, Struts+ Hibernate+ Spring has become a lightweight J2EE Development the standard configuration is called SHS classic combination, which is currently the Java programmer must master the skills. This book is a small example of a combination of practical book, readers can each case personally practice.)

本代码只是简单实现了办公系统的一小部分，使用struts等框架，只适合初学者参考。(This code simply implements a small part of office systems, such as using the struts framework, reference is only suitable for beginners.)

说明：  设计一个交通信号灯类： （1）变量：位置、颜色（红、黄、绿）、显示时间（秒）。 （2）方法：切换信号灯。 创建并启动两个线程（东西向、南北向）同时运行。 3．实验要求 （1）设计线程。 （2）设计路口信号灯示意图界面。 （3）进一步将每个方向的信号灯分成3种车道灯：左转、直行和右转。 （4）根据车流量进行时间的模糊控制。(Design a traffic light class: (1) variables: location, color (red, yellow, green), display time (seconds). (2) Method: switch the signal lamp. Create and start two threads (east-west, north-south) running at the same time. 3. Experiment requirements (1) design thread. (2) Design schematic interface of intersection signal light. (3) Further, the signal lights in each direction are divided into three kinds of lane lights: left turn, straight ahead and right turn. (4) Fuzzy control of time according to traffic flow.)

说明：  国家水质评估（NAWQA）区域特征化工具箱的1.0版。ArcGIS（版本9.3和9.3.1）可使用。工具箱由一组自定义工具组成，这些工具实现了NAWQA项目使用的地理信息系统（GIS）技术，用于描述含水层区域、流域和取样井的特征。(This is release 1.0 of the National Water-Quality Assessment (NAWQA) Area-Characterization Toolbox. These tools are designed to be accessed using ArcGIS Desktop software (versions 9.3 and 9.3.1). The toolbox is composed of a collection of custom tools that implement geographic information system (GIS) techniques used by the NAWQA Program to characterize aquifer areas, drainage basins, and sampled wells.)

对彩信编程的一点经验，大家分享，希望能给你一个帮助(right MMS 1:00 programming experience, we share the hope that would give you a help)

License Plate Recognition or LPR is an image-processing technology used to identify vehicles by their license plates. This technology is used in various applications involving security, traffic, law enforcement, public safety and transportation sectors. It mainly uses software code that enables computer systems to read automatically the registration number (license number) of vehicles digital pictures.
