回复帖子

　　分析回复帖子

　　拿到paste.title标签

  1.                                         <a href="${pageContext.request.contextPath }/PasteAction_getDetail?pasteid=<s:property value="#paste.id"/>">
  2.                                             <s:property value="#paste.title" />
  3.                                         </a>

　　编写查看帖子模型驱动

　　帖子模型驱动Web层

  1.     //查看帖子详细信息
  2.     public String getDetail() throws Exception{
  3.  
  4.         Paste paste = pasteService.findAllPasteByIdReturnPaste(pasteid);
  5.  
  6.         ActionContext.getContext().put("paste", paste);
  7.  
  8.         return "detail";
  9.     }
  10.

　　帖子模型驱动Service层

  1.     public Paste findAllPasteByIdReturnPaste(String pasteid) {
  2.  
  3.         return pasteDao.findPasteByIdReturnPaste(pasteid);
  4.     }

　　帖子模板Dao层

  1.     public Paste findPasteByIdReturnPaste(String pasteid) {
  2.         Session session = getHibernateTemplate().getSessionFactory().getCurrentSession();
  3.         String sql = "select * from paste where id = ?";
  4.         NativeQuery query = session.createSQLQuery(sql);
  5.         query.addEntity(Paste.class);
  6.         query.setParameter(1, pasteid);
  7.         Paste result = (Paste) query.uniqueResult();
  8.         return result;
  9.     }

　　帖子前端页面

　　

  1. <!DOCTYPE html>
  2. <html>

　　当浏览一个帖子时，帖子的浏览数目需要+1　　（数据库中glanceover+1）

　　Service层中findAllPasteByIdReturnPaste()编写传送数据到Dao层修改数据库中glanceover语句

  1.     public Paste findAllPasteByIdReturnPaste(String pasteid) {
  2.  
  3.         pasteDao.addPasteGlanceover(pasteid);
  4.         //SQL语句写法：update paste set glanceover = glanceover+1 where id = ?;
  5.  
  6.         return pasteDao.findPasteByIdReturnPaste(pasteid);
  7.     }

　　帖子回复glanceover+1

  1. public void addPasteGlanceover(String pasteid) {
  2.         Session session = getHibernateTemplate().getSessionFactory().getCurrentSession();
  3.         String sql = "update paste set glanceover = glanceover+1 where id = ?";
  4.         NativeQuery query = session.createSQLQuery(sql);

PasteDao.java

　　为了尽可能少的访问数据，利用数据持久状态

  1.     public Paste findPasteByIdReturnPaste(String pasteid) {
  2.  
  3.         //pasteDao.addPasteGlanceover(pasteid);
  4.         //数据库SQL语句：update paste set glanceover = glanceover+1 where id = ?;
  5.         Paste paste = pasteDao.findPasteByIdReturnPaste(pasteid);
  6.         paste.setGlanceover(paste.getGlanceover()+1);
  7.         return paste;
  8.     }

　　编写帖子模块最近热帖和最近热议

　　帖子模块的最近热帖和最近热议应该动态从数据库中获取

　　PasteAction.java

  1.  //查看帖子详细信息
  2.     public String getDetail() throws Exception{
  3.  
  4.         //得到最近热帖
  5.         PageBean glanceoverPageBean = pasteService.getGlanceoverPageBean(null);
  6.         ActionContext.getContext().put("glanceoverPageBean", glanceoverPageBean);
  7.  
  8.         //得到最近热议
  9.         PageBean ansnumPageBean = pasteService.getAnsnumPageBean(null);
  10.         ActionContext.getContext().put("ansnumPageBean", ansnumPageBean);
  11.  
  12.         Paste paste = pasteService.findPasteByIdReturnPaste(pasteid);
  13.         ActionContext.getContext().put("paste", paste);
  14.  
  15.         return "detail";
  16.     }

　　修改detail.jsp

  7.     public void setAnswerPasteSet(Set<Paste> answerPasteSet) {
  8.         this.answerPasteSet = answerPasteSet;
  9.     }

　　在User.hbm.xml中添加一对多的关系

  1.         <set name="answerPasteSet">
  2.             <key  column="pasteid"></key>
  3.             <one-to-many class="Answer"/>
  4.         </set>

　　分析用户帖子一对多的关系

　　在Paste.java中添加HashSet<User>用户回复

  1.     private Set<User> userAnswerSet = new HashSet<User>();
  2.  
  3.     public Set<User> getUserAnswerSet() {
  4.         return userAnswerSet;
  5.     }
  6.     public void setUserAnswerSet(Set<User> userAnswerSet) {
  7.         this.userAnswerSet = userAnswerSet;
  8.     }

　　Paste.hbm.xml中绑定用户与表一对多的关系

  1.      <set name="userAnswerSet">
  2.          <!-- 外键的类名 -->
  3.          <key column="userid"></key>
  4.          <!-- 外键的类名的类 -->
  5.          <one-to-many class="Answer"/>
  6.      </set>

detail.jsp

　　此时发现跳转过来的页面全部问题、最近热帖、最近热议、专家排行榜都是空的白的，接下来需要实现重定向到Action

　　添加addAnswer()请求，如果用户成功回复，则返回"toDetail“

  1.     public String addAnswer() throws Exception {    
  2.  
  3.         User user =    (User) ActionContext.getContext().getSession().get("user");
  4.         if(user == null)
  5.         {
  6.             ActionContext.getContext().put("error", "未登录不能回复！！");
  7.             return "error";
  8.         }
  9.  
  10. //        //回复时间
  11. //        private String anstime;
  12.         Date date = new Date(System.currentTimeMillis());
  13.         SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
  14.         String anstime = format.format(date);
  15.         answer.setAnstime(anstime);
  16. //        //同意数
  17. //        private Integer agree;
  18.         answer.setAgree(0);
  19. //        //是否解决
  20. //        private Integer solve;
  21.         answer.setSolve(0);
  22. //
  23. //        private User user;
  24.         answer.setUser(user);
  25. //
  26. //        private Paste paste;
  27.         Paste paste = pasteService.findPasteByIdReturnPaste(pasteid);
  28.         answer.setPaste(paste);
  29.  
  30.         answerService.addAnswer(answer,paste);
  31.         answerService.addAnswer(answer);
  32.  
  33.         return "toDetail";
  34.     }

　　在struts.xml中配置toDetail结果集成重定向到action中

  1.     <action name="AnswerAction_*" class="com.Gary.web.AnswerAction" method="{1}">
  2.             <result name="error">/login.jsp</result>

  5.                 <param name="actionName">PasteAction_getDetail</param>
  6.                 <!-- struts不认识pasteid则会封装到重定向的action中 -->
  7.                 <param name="pasteid">${pasteid}</param>
  8.             </result>

AnswerDao.java

　　可以看到，进入帖子后，帖子浏览数目+1，当增加回帖时，帖子数+1，当删除回帖时，帖子数-1

　　添加属性与元数据字段

  1.     private String answerid;
  1.         <property name="answerid" column="answerid"></property>

　　

　　分析采纳帖子

　　detail.jsp

  1.                                         <s:if test="#session.user.username==#paste.user.username && #paste.solve==0">
  2.                                             <span class="jieda-accept" type="accept">
  3.                                                 <a href="${pageContext.request.contextPath }/PasteAction_solvePaste?answerid=<s:property value="#answer.id"/>&pasteid=<s:property value="#paste.id"/>" class="layui-btn  layui-btn-small">采纳</a>
  4.                                             </span>
  5.                                         </s:if>

　　Web层：采纳用户回帖

  1.     public String solvePaste() throws Exception{
  2.  
  3.         pasteService.solvePasteByIdAndAnswerid(pasteid,paste.getAnswerid());
  4.         ActionContext.getContext().put("pasteid", pasteid);
  5.  
  6.         return "toDetail";
  7.     }

　　Service层：获得Web层数据传递到Dao层

  1.     public void solvePasteByIdAndAnswerid(String pasteid, String answerid) {
  2.         pasteDao.solvePasteByIdAndAnswerid(pasteid,answerid);
  3.     }

　　Dao层：进行数据的处理

  1.     public void solvePasteByIdAndAnswerid(String pasteid, String answerid) {
  2.         Session session = getHibernateTemplate().getSessionFactory().getCurrentSession();
  3.         String sql ="update paste set solve = 1, answerid = ? where id = ?";
  4.         NativeQuery query = session.createSQLQuery(sql);
  5.         query.setParameter(1, answerid);
  6.         query.setParameter(2, pasteid);
  7.         query.executeUpdate();
  8.     }
