拿到paste.title标签
<a href="${pageContext.request.contextPath }/PasteAction_getDetail?pasteid=<s:property value="#paste.id"/>"> <s:property value="#paste.title" /> </a>
编写查看帖子模型驱动
帖子模型驱动Web层
//查看帖子详细信息 public String getDetail() throws Exception{ Paste paste = pasteService.findAllPasteByIdReturnPaste(pasteid); ActionContext.getContext().put("paste", paste); return "detail"; }
帖子模型驱动Service层
public Paste findAllPasteByIdReturnPaste(String pasteid) { return pasteDao.findPasteByIdReturnPaste(pasteid); }
帖子模板Dao层
public Paste findPasteByIdReturnPaste(String pasteid) { Session session = getHibernateTemplate().getSessionFactory().getCurrentSession(); String sql = "select * from paste where id = ?"; NativeQuery query = session.createSQLQuery(sql); query.addEntity(Paste.class); query.setParameter(1, pasteid); Paste result = (Paste) query.uniqueResult(); return result; }

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

为了尽可能少的访问数据，利用数据持久状态
public Paste findPasteByIdReturnPaste(String pasteid) { //pasteDao.addPasteGlanceover(pasteid); //数据库SQL语句：update paste set glanceover = glanceover+1 where id = ?; Paste paste = pasteDao.findPasteByIdReturnPaste(pasteid); paste.setGlanceover(paste.getGlanceover()+1); return paste; }
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
//查看帖子详细信息 public String getDetail() throws Exception{ //得到最近热帖 PageBean glanceoverPageBean = pasteService.getGlanceoverPageBean(null); ActionContext.getContext().put("glanceoverPageBean", glanceoverPageBean); //得到最近热议 PageBean ansnumPageBean = pasteService.getAnsnumPageBean(null); ActionContext.getContext().put("ansnumPageBean", ansnumPageBean); Paste paste = pasteService.findPasteByIdReturnPaste(pasteid); ActionContext.getContext().put("paste", paste); return "detail"; }
修改detail.jsp
<div class="edge"> <dl class="fly-panel fly-list-one"> <dt class="fly-panel-title">最近热帖</dt> <s:iterator value="#glanceoverPageBean.list" var="paste"> <dd> <a href="${pageContext.request.contextPath }/PasteAction_getDetail?pasteid=<s:property value="#paste.id"/>"> <s:property value="#paste.title" /> </a> <span> <i class="iconfont"></i> <s:property value="#paste.glanceover" /> </span> </dd> </s:iterator> </dl> <dl class="fly-panel fly-list-one"> <dt class="fly-panel-title">近期热议</dt> <s:iterator value="#ansnumPageBean.list" var="paste"> <dd> <a href="${pageContext.request.contextPath }/PasteAction_getDetail?pasteid=<s:property value="#paste.id"/>"> <s:property value="#paste.title" /> </a> <span> <i class="iconfont"></i> <s:property value="#paste.ansnum" /> </span> </dd> </s:iterator> </dl>

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“
public String addAnswer() throws Exception { User user = (User) ActionContext.getContext().getSession().get("user"); if(user == null) { ActionContext.getContext().put("error", "未登录不能回复！！"); return "error"; } // //回复时间 // private String anstime; Date date = new Date(System.currentTimeMillis()); SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss"); String anstime = format.format(date); answer.setAnstime(anstime); // //同意数 // private Integer agree; answer.setAgree(0); // //是否解决 // private Integer solve; answer.setSolve(0); // // private User user; answer.setUser(user); // // private Paste paste; Paste paste = pasteService.findPasteByIdReturnPaste(pasteid); answer.setPaste(paste); answerService.addAnswer(answer,paste); answerService.addAnswer(answer); return "toDetail"; }
在struts.xml中配置toDetail结果集成重定向到action中
<action name="AnswerAction_*" class="com.Gary.web.AnswerAction" method="{1}"> <result name="error">/login.jsp</result> <!-- 重定向到Action --> <result name="toDetail" type="redirectAction"> <param name="actionName">PasteAction_getDetail</param> <!-- struts不认识pasteid则会封装到重定向的action中 --> <param name="pasteid">${pasteid}</param> </result> </action> </package>
