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
