基于mvc的web文章系统----总体框架、文章显示、日志管理、验证码模块

基于MVC的WEB文章系统总体框架、文章显示、日志管理、验证码模块模块开发卷宗1标题软件系统名称和标识符名称基于MVC的WEB文章系统标识符WEB文章系统模块名称和标识符名称系统总体框架、日志管理、EMAIL在线回复、验证码标识符框架、日志、验证码程序编制员签名李正峰修改完成日期2005528卷宗序号（说明本卷宗在整个卷宗中的序号）编排日期20055282模块开发情况表3功能说明1、总体框架网站的总体架构设计2、文章显示对添加的文章/公告在网页中以标题列表、完全显示等方式分类显示出来，并可以添加用户评论以及分页显示。3、日志管理对后台的操作完全记录，并且以列表的形式显示每条日志。4、EMAIL自动回复用户注册成功，自动在线通过用户的EMAIL地址给予回复，向用户发送欢迎信息，无需任何人工干预。5、验证码管理员登录后台管理时，需要在登录的时候输入验证码，验证正确才能登录后台。以防止暴力破解管理员用户密码。4设计说明1、总体框架模块功能考虑网站的总体架构，由于是网上文章管理系统，要符合一般网站的要求，所以使用了流行的JSPWEB编程语言，显示页面使用STRUTS技术，尽量简化开发，充分利用了其MVC模式的优越性，后台管理部分使用JAVABEANJSP开发，做到逻辑处理与显示的分离。流程分析2、文章显示模块模块功能本模块是整个系统中的显示层，负责文章的显示功能，包括列表显示，内容显示，分页管理，用户评论等。本层使用JAVA中的STRUTS框架进行开发，充分利用了其MVC模式的优越性。流程分析用户界面3、日志管理模块模块功能记录管理员后台管理的所有操作，以便出现管理错误，可以很快的查找出是哪个用户做的什么操作，方便恢复。实现了网站管理的安全性。本模块使用一个用于日志记录的APACHE开源项目LOG4J进行开发，此项目经过长期的实践检验，被认为是JAVA日志管理方面最优秀的解决方案之一。流程分析用户界面4、EMAIL自动回复模块功能读取用户注册信息中的EMAIL信息，按照预先设定好的信件内容，对注册用户自动发送欢迎注册邮件。本功能使用JAVAMAIL编写，使网站具有在线发送EMAIL的功能。流程分析5、验证码模块功能通过随机函数，生成一个字符串，并把字符串生成JPG图片，显示在管理员登录界面上，管理员登录后台管理时，需要在登录的时候输入验证码，验证正确才能登录后台。以防止暴力破解管理员用户密码。用户界面5数据字典用户表（USERS）字段名称描述数据类型字段长度可否为空IDID号INTAUTO_INCREMENT否USERNAME管理员名称VARCHAR20否PASSWORD管理员密码VARCHAR25否SEX性别INT否NICKNAME昵称VARCHAR50否QUESTION密码保护问题VARCHAR100否ANSWER密码保护答案VARCHAR100否BIRTHDAY生日DATETIME否QQQQ号码INT否UCUC号码INT否ADDRESS地址VARCHAR200否EMAILEMAILVARCHAR50否SELFDESC个人描述VARCHAR255否ARTICLES文章数INT否REGISTRYIP注册IPVARCHAR50否REGISTRYDATE注册时间DATETIME否LASTLOGIN最后登陆时间DATETIME否LOGINTIMES登陆次数INT否CHARM魅力值INT否ISACTIVE帐号是否被激活INT否ISADMIN是否是管理员INT否VERIFYCODE激活代码VARCHAR50否文章分类表（CATEGORY）字段名称描述数据类型字段长度可否为空IDID号INTAUTO_INCREMENT否PARENTID父节点INT否NAME名称VARCHAR50否FULLNAMEFULLNAME全称VARCHAR250否文章表（ARTICLE）字段名称描述数据类型字段长度可否为空IDID号INTAUTO_INCREMENT否CATEGORY文章分类INT否TITLE文章标题VARCHAR50否CONTENT文章内容TEXT否HITS点击数INT否AUTHOR文章作者VARCHAR20否ADDTIME添加时间DATETIME否KEYWORD关键字VARCHAR30否ISRECOMMANDATION是否推荐INT否EDITOR编辑VARCHAR20否WRITEFROM来自VARCHAR30否评论表（REMARK）字段名称描述数据类型字段长度可否为空IDID号INTAUTO_INCREMENT否NEWSID所属文章IDINT否REUSER回复人VARCHAR50否RECONTENT回复内容VARCHAR255否MAIL回复人EMAILVARCHAR30否REDATE回复时间DATETIME否REIP回复IPVARCHAR50否日志表（LOGS）字段名称描述数据类型字段长度可否为空IDID号INTAUTO_INCREMENT否USERNAME登陆管理员VARCHAR30否EVENT操作事件VARCHAR100否LOGTIME操作时间DATETIME否IP操作IP地址VARCHAR50否IP地址表（IPADDRESS）字段名称描述数据类型字段长度可否为空IP1开始IPFLOAT否IP2结束IPFLOAT否COUNTRY国家VARCHAR20否CITY城市VARCHAR50否53程序代码531数据库连接DATABASECONNJAVAIMPORTJAVASQLCONNECTIONIMPORTJAVASQLSQLEXCEPTIONIMPORTJAVAXNAMINGCONTEXTIMPORTJAVAXNAMINGNAMINGEXCEPTIONIMPORTJAVAXNAMINGINITIALCONTEXTIMPORTJAVAXSQLDATASOURCEPUBLICCLASSDATABASECONNPUBLICSTATICSYNCHRONIZEDCONNECTIONGETCONNECTIONTHROWSEXCEPTIONTRYCONTEXTCTXNEWINITIALCONTEXTCONTEXTENVCTXCONTEXTCTXLOOKUP“JAVACOMP/ENV“/TOMCAT/JBOSSUSETHISMETHOD/DATASOURCEDSDATASOURCECTXLOOKUP“JAVA/LEE“RETURNDSGETCONNECTIONCATCHSQLEXCEPTIONETHROWECATCHNAMINGEXCEPTIONETHROWE532显示文章NEWSDATAJAVAIMPORTJAVASQLCONNECTIONIMPORTJAVASQLSTATEMENTIMPORTJAVASQLPREPAREDSTATEMENTIMPORTJAVASQLRESULTSETIMPORTJAVAUTILARRAYLISTIMPORTJAVAUTILCOLLECTIONIMPORTJAVAUTILITERATORIMPORTJAVAUTILDATEIMPORTJAVAUTILLOCALEIMPORTJAVATEXTDATEFORMATIMPORTCNEDUCUMTUTILDATABASECONNIMPORTCNEDUCUMTBEANCATEGORYDATAIMPORTCNEDUCUMTBEANCATEGORYPUBLICCLASSNEWSDATAPRIVATESTATICINTTOTALNEWS0PUBLICSTATICINTGETTOTALNEWSRETURNTOTALNEWS/GETNEWSICLEBYNEWSICLEIDPARAMIDINTPARAMDATASOURCEDATASOURCETHROWSEXCEPTIONRETURNNEWSICLE/PUBLICSTATICNEWSGETNEWSINTIDTHROWSEXCEPTIONDATEFORMATDATEFDATEFORMATGETDATEINSTANCEDATEFORMATFULL,LOCALECHINADATEFORMATTIMEFDATEFORMATGETTIMEINSTANCEDATEFORMATFULL,LOCALECHINACONNECTIONCONNNULLPREPAREDSTATEMENTPSTMTNULLRESULTSETRSNULLNEWSNEWSNEWNEWSTRYCONNDATABASECONNGETCONNECTIONPSTMTCONNPREPARESTATEMENT“SELECTFROMNEWSWHEREID“PSTMTSETINT1,IDRSPSTMTEXECUTEQUERYIFRSNEXTNEWSSETIDRSGETINT“ID“NEWSSETCATEGORYRSGETINT“CATEGORY“NEWSSETTITLERSGETSTRING“TITLE“NEWSSETCONTENTRSGETSTRING“CONTENT“NEWSSETHITSRSGETINT“HITS“NEWSSETAUTHORRSGETSTRING“AUTHOR“NEWSSETADDTIMEDATEFFORMATRSGETTIMESTAMP“ADDTIME“TIMEFFORMATRSGETTIMESTAMP“ADDTIME“NEWSSETKEYWORDRSGETSTRING“KEYWORD“NEWSSETISRECOMMANDATIONRSGETBOOLEAN“ISRECOMMANDATION“NEWSSETEDITORRSGETSTRING“EDITOR“NEWSSETWRITEFROMRSGETSTRING“WRITEFROM“ELSETHROWNEWEXCEPTION“SORRYTHENEWSNOTFOUND“FINALLYIFRSNULLRSCLOSEIFPSTMTNULLPSTMTCLOSEIFCONNNULLCONNCLOSERETURNNEWS/GETNEWS1IFCATEGORY0THENGETALLCATEGORYNEWSICLESELSEGETTHENCATEGORYNEWSICLES2IFTOP0THENGETALLNEWSICLESELSEGETTOPNEWSICLEPARAMCATEGORYINTPARAMTOPINTPARAMDATASOURCEDATASOURCETHROWSEXCEPTIONRETURNARRAYLIST/PUBLICSTATICCOLLECTIONGETNEWSINTCATEGORY,INTTOPTHROWSEXCEPTION/DATEFORMATDATEFDATEFORMATGETDATEINSTANCEDATEFORMATFULL,LOCALECHINA/DATEFORMATTIMEFDATEFORMATGETTIMEINSTANCEDATEFORMATFULL,LOCALECHINA/间隔一周的为最新/LONGBETWEENTIME72460601000DATECURRENTDATENEWDATECOLLECTIONALLNEWSNEWARRAYLISTNEWSNEWSNULLCONNECTIONCONNNULLRESULTSETRSNULLSTATEMENTSTMTNULLSTRINGSQLNULLTRYCONNDATABASECONNGETCONNECTIONSTMTCONNCREATESTATEMENTIFCATEGORY0IFTOP0SQL“SELECTFROMNEWSORDERBYIDDESC“ELSESQL“SELECTFROMNEWSORDERBYIDDESCLIMIT0,“TOP“ELSEIFTOP0SQL“SELETCFROMNEWSWHERECATEGORY“CATEGORY“ORDERBYIDDESC“ELSESQL“SELECTFROMNEWSWHERECATEGORY“CATEGORY“ORDERBYIDDESCLIMIT0,“TOP“RSSTMTEXECUTEQUERYSQLWHILERSNEXT
