基于Struts2的供求信息网设计(三)

六，项目功能模块分析

Struts.xml配置文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">

6.1首页模块

用户在浏览器端请求地址http://localhost:8080/HustSchool/index.jsp，但是在index.jsp中重定向homeaction,经过拦截器拦截在Struts.xml配置文件中找到对应的action，执行代码返回一个字符串，Struts.xml配置文件中的action标签的result标签中找到对应的jsp或action
Index.jsp

Bug分析：

由于时间紧，完成了3个模块，信息快速搜索栏的后台处理代码没来得及写

6.2兼职信息模块

显示兼职信息功能：

点击上面“兼职信息”，会跳转到http://localhost:8080/HustSchool/joblistaction,会跳转到joslistaction，JobListAction中获取lecture表中的讲座信息，并且分页显示

JobListAction.java

package com.hust.Action;import java.util.List;import com.hust.tools.PageQueryDao;
import com.hust.Bean.JobBean;
import com.hust.Bean.JobBean;
import com.hust.Dao.JobDao;
import com.hust.tools.MySuperAction;public class JobListAction extends MySuperAction {/*** */private static final long serialVersionUID = 1L;public String execute(){//JobDao jobdao=new JobDao();//List<JobBean> joblist=jobdao.GetJobList(); int currpage=1;if(request.getParameter("page")!=null){currpage=Integer.parseInt(request.getParameter("page"));}PageQueryDao pagedao=new PageQueryDao();List<JobBean> joblist=pagedao.getJobPageList(currpage);//查询当前页记录int pages;   //计算查询总页数String sql="select count(*) from job";int count=pagedao.FindCounts(sql);if(count%JobBean.PAGE_SIZE==0){pages=count/JobBean.PAGE_SIZE;}else{pages=count/JobBean.PAGE_SIZE+1;}StringBuffer sb=new StringBuffer();sb.append("<a href='joblistaction?page=1'>首页</a>");sb.append(" ");//构建分页条for(int i=1;i<=pages;i++){if(i==currpage){sb.append("『" + i + "』");}else{sb.append("<a href='joblistaction?page="+i+"'>"+i+"</a>");}sb.append(" ");}sb.append("<a href='joblistaction?page="+pages+"'>尾页</a>");request.setAttribute("joblist", joblist);       request.setAttribute("bar", sb.toString());return SUCCESS;}
}

这部分为了美观学习了很多ＣＳＳ的知识，大多时间都换在了修改样式外观上了。
发布兼职信息功能：
点击“我要发布”，可以进入发布兼职信息页面releasejob.jsp

6.3讲座信息模块
点击标题栏“讲座信息”进入讲座信息模块，这个模块主要有“华科大讲座”，“武汉讲座”，“公益讲座”，“讲座活动”，“中国讲座网”这5个模块，但是目前只做了“华科大讲座”和“武汉讲座”
这二者的区分是在lecture表中用“0”，“1”标志区分的

点击标题栏“讲座信息”的链接是：http://localhost:8080/HustSchool/lecturelistaction!HustLecture, 先访问lecturelistaction中的HustLecture方法

<!-- lecture列表 --><action name="lecturelistaction" class="com.hust.Action.LectureListAction"><result name="success">lecturelist.jsp</result></action>

LectureListAction.java中只有两个方法HustLecture，WuhanLecture,这两个方法

查看讲座详细信息：
对每一个讲座都可以点击链接进入详细信息页面
当点击链接时请求提交到showlectureaction http://localhost:8080/HustSchool/showlectureaction?id=10, 把每个讲座的Id传给showlectureaction,在action中根据Id查询数据库
ShowLectureAction.java

package com.hust.Action;import com.hust.Bean.LectureBean;

import com.hust.tools.MySuperAction;public class ShowLectureAction extends MySuperAction{/*** */private static final long serialVersionUID = 1L;public String execute(){int id=Integer.valueOf(request.getParameter("id"));//获得讲座的id，查询整个讲座的信息System.out.println(id);LectureDao lecturedao=new LectureDao();LectureBean lecture=lecturedao.getLecture(id);request.setAttribute("lecture", lecture);return SUCCESS;}}
