《JSP全程开发实录:都市供求信息网源码》是一个深入浅出的教程,旨在帮助开发者通过实际项目——都市供求信息网的构建,全面掌握JSP技术的应用。本资源包含了一系列的源代码文件,旨在提供一个实战平台,让学习者能够理论与实践相结合,提升在Web开发领域的技能。 JSP(JavaServer Pages)是Java平台上的一种动态网页技术,它允许开发者将HTML代码与Java代码混合编写,从而实现动态内容的生成。在都市供求信息网的开发过程中,JSP被用于处理用户请求、展示数据和交互逻辑。这个项目可能涵盖了以下几个关键知识点: 1. **JSP基础**:包括JSP语法、指令(page、include、taglib)、脚本元素(Scriptlets、Expressions、Declarations)以及JSP内置对象(如request、response、session等)的使用。 2. **Servlet**:作为JSP的基础,理解Servlet的工作原理和生命周期至关重要。在项目中,Servlet可能被用来处理HTTP请求,与数据库交互,或者进行业务逻辑处理。 3. **MVC模式**:都市供求信息网可能采用了Model-View-Controller架构,JSP作为View层,处理视图展示;Servlet或JavaBeans作为Controller,控制业务逻辑;而数据模型通常由Java类或DAO(Data Access Object)实现,负责与数据库交互。 4. **数据库操作**:项目可能涉及到MySQL、Oracle等数据库的使用,包括SQL查询、连接池管理、事务处理等。JDBC(Java Database Connectivity)是Java连接数据库的标准接口,学习者需要熟悉其基本操作。 5. **HTML/CSS/JavaScript**:前端基础,用于构建用户界面。HTML定义页面结构,CSS进行样式布局,JavaScript则提供动态交互功能,三者结合实现用户体验的优化。 6. **AJAX**:异步JavaScript和XML,可以实现局部刷新,提高用户体验,可能在搜索、添加、删除等功能中应用。 7. **JSTL(JavaServer Pages Standard Tag Library)**:JSP标准标签库,提供了一组标准的标签,简化了JSP页面的编写,提高了代码的可读性和可维护性。 8. **Filter和Listener**:在项目中可能用到过滤器(Filter)来拦截和处理请求,监听器(Listener)则用于监听应用的特定事件,如会话创建、销毁等。 9. **安全性**:了解如何防止SQL注入、XSS攻击等常见安全问题,确保网站信息的安全。 通过这个项目,学习者不仅可以深入理解JSP及其相关技术,还能了解到实际项目开发中的流程和规范,包括需求分析、设计、编码、测试和部署等环节。同时,对于团队协作和版本控制工具如Git的使用也会有所涉猎。 压缩包中的文件01可能是项目的初始化文件或第一部分源代码,包括JSP页面、Servlet类、配置文件等。进一步研究这些文件,可以更具体地了解项目的实现细节,并从中学习和借鉴。
