Description: springlive的例子，从搭建工作环境，然后熟悉业务流程、工作计划、进度控制等等项目相关的东东开始，到今天一个功能完备的管理系统已经出现在我的眼前，感到一种成就感。
想一想，起初对STRUTS只停留在书本的认识上，也就是能够看个明白，不过经过这个月的摸爬滚打也算有些入门了，也了解了STRUTS项目是如何进行开发的。
记得第一天开工作计划是这样的：先是开发数据库值对象（VO）－数据库访问对象（DAO）－DAO的测试用例－业务逻辑对象（BO）－BO的测试用例－JSP页面－ACTIONFORM－ACTION。大概是这样的一个流程吧，现在分别说一下各个阶段是如何进行的。

Description: 现阶段内置模板可以生成的包括: 可以生成java的hibernat model+annotation,hibernate model+xml,dao,manager,struts+struts2 action类 生成jsp的增删改查. (生成的代码与rapid-framework绑定才比较有意义) 通常代码生成器存在的问题. * 二次开发困难 * 过于智能,自动插入我们的项目中,程序员还需考虑旧的代码会不会被覆盖的问题 * 没有将存放模板的目录名称及文件名称利用起来,导致还需配置每个模板文件生成的文件名,目录结构 具体请查看我写的文章:为何代码生成器都要这么智能呢? 本代码生成器的特性 * 基于FreeMarker模板语言 * 基于数据库,并支持多种数据库(mysql,sql server,oracle测试通过) * 半手工方式,生成的代码放在某个目录,再手工拷贝回来工作区 * 易于做二次开发,整个生成器本身就是java源代码,源代码核心十分精简,并且鼓励你做修改代码,也可以作为任何语言的代码生成器 * 配置简单,只有一个配置文件generator.properties * 以application方式运行生成器,生成不同的table直接修改相关java代码即可 * 将文件系统的目录名称及文件名称作为生成器的一部分,模板文件的的名称与目录名称可以直接引用相关变量,如 ${basepackage}/${className}.java (${className}=Blog,则会生成Blog.java) * 以@testExpression结尾的模板文件为有条件忽略,如果testExpression的值在数据模型为true则生成该文件,生成的文件不会包含@testExpression,反之则不生成该文件(应用场景:用于在是否要生成hibernate联合主建的文件中) * 支持文件插入操作,如模板输出生成的地方已经有该同名的文件存在,并且文件中有包含"webapp-generator-insert- location"标记,则模板生成的内容会插入在该标记之后.该特性对如生成的spring配置内容插入spring配置文件十分有用

Description: LyBBS论坛系统主要是为了完成信息的发布与交流，采用基于JSP+Servlet+Action的MVC架构，采用Struts1.2标准，兼容于Java 2 Standard Edition 1.3、1.4和1.5(5.0)，兼容于Windows/Linux等多种操作系统平台，兼容于Tomcat/Resin/WebLogic/WebSphere等多种JSP服务器容器，兼容于MySQL /DB2/Oracle/MSSQL系列数据库。采用Model II 架构，前台JSP主要完成数据显示，Action类负责前台数据的接收和处理，DAO层完成数据库的查询、更新、删除、插入等操作，论坛对于常用数据使用了大量的缓存，我们针对不同的类型数据设计了不同数据缓存类，对数据库我们采用了数据库连接池，用户可以在配置文件中配置不同的连接池或者不使用连接池，对表操作也采用了预处理、批处理、事务处理等多种方式，用户可以在配置文件中配置数据库连接参数，包括连接数，超过连接数的处理方式，是否缓存SQL，缓存多少的SQL等等，目前，论坛可以非常有效的管理内存，提高稳定性、并发性和运行效率。

Description: 公司内部用户、任务与计划管理的系统，B/S结构；该系统使用Struts框架与MySql数据库，Tomcat6.0作Web服务器，使用CVS进行源 代码版本控制，使用MyEclipse6.5作开发工具。
使用该系统的角色有系统管理员、主管和员工；系统管理员可以添加人员并分配其角色(主管和员工)，主管可以制定任务、查看自已布置的任务、跟踪实施中的任 务、查看部下的人员；员工可以查看主管布置的任务、为任务制订计划、自已制订的计划的管理、反馈与提交计划；
