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

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;

为了尽可能少的访问数据，利用数据持久状态

}
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";
}

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“
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>
