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

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">

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

System.out.println(id);
LectureDao lecturedao=new LectureDao();
LectureBean lecture=lecturedao.getLecture(id);
request.setAttribute("lecture", lecture);
return SUCCESS;
}
}
处理完成后返回到lecture.jsp
