生活随笔
收集整理的這篇文章主要介紹了
基于Struts2的供求信息网设计(三)
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
六，項目功能模塊分析

用戶在瀏覽器端請求地址http://localhost:8080/HustSchool/index.jsp， 但是在index.jsp中重定向homeaction,經過攔截器攔截在Struts.xml配置文件中找到對應的action，執行代碼返回一個字符串，Struts.xml配置文件中的action標簽的result標簽中找到對應的jsp或action

Bug分析：
由于時間緊，完成了3個模塊，信息快速搜索欄的后臺處理代碼沒來得及寫
6.2兼職信息模塊
顯示兼職信息功能：
點擊上面“兼職信息”，會跳轉到http://localhost:8080/HustSchool/joblistaction,會跳轉到joslistaction，JobListAction中獲取lecture表中的講座信息，并且分頁顯示
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);//查詢當前頁記錄int pages; //計算查詢總頁數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'>首頁</a>");sb.append(" ");//構建分頁條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+"'>尾頁</a>");request.setAttribute("joblist", joblist); request.setAttribute("bar", sb.toString());return SUCCESS;} }
這部分為了美觀學習了很多ＣＳＳ的知識，大多時間都換在了修改樣式外觀上了。
發布兼職信息功能：
點擊“我要發布”，可以進入發布兼職信息頁面releasejob.jsp

6.3講座信息模塊
點擊標題欄“講座信息”進入講座信息模塊，這個模塊主要有“華科大講座”，“武漢講座”，“公益講座”，“講座活動”，“中國講座網”這5個模塊，但是目前只做了“華科大講座”和“武漢講座”
這二者的區分是在lecture表中用“0”，“1”標志區分的
點擊標題欄“講座信息”的鏈接是：http://localhost:8080/HustSchool/lecturelistaction!HustLecture, 先訪問lecturelistaction中的HustLecture方法

查看講座詳細信息：
對每一個講座都可以點擊鏈接進入詳細信息頁面
當點擊鏈接時請求提交到showlectureaction http://localhost:8080/HustSchool/showlectureaction?id=10, 把每個講座的Id傳給showlectureaction,在action中根據Id查詢數據庫
ShowLectureAction.java
package com.hust.Action;import com.hust.Bean.LectureBean; import com.hust.Dao.LectureDao; 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"));//獲得講座的id，查詢整個講座的信息System.out.println(id);LectureDao lecturedao=new LectureDao();LectureBean lecture=lecturedao.getLecture(id);request.setAttribute("lecture", lecture);return SUCCESS;}} 處理完成后返回到lecture.jsp
