設計思路：

1、評論數和點擊數都是文章的屬性之一，在文章pojo類添加這兩個屬性。

	PRivate Integer hasread;	private Integer comment;		public Integer getComment() {		return comment;	}	public void setComment(Integer comment) {		this.comment = comment;	}	public Integer getHasread() {		return hasread;	}	public void setHasread(Integer hasread) {		this.hasread = hasread;	}
2、新建一個評論pojo類，包含評論內容，評論用戶名，評論文章id屬性。
public class Criticism {	private Integer id;	private Integer Aid;	private String content;	private String username;		public Integer getId() {		return id;	}	public void setId(Integer id) {		this.id = id;	}	public Integer getAid() {		return Aid;	}	public void setAid(Integer aid) {		Aid = aid;	}	public String getContent() {		return content;	}	public void setContent(String content) {		this.content = content;	}	public String getUsername() {		return username;	}	public void setUsername(String username) {		this.username = username;	}	}
3、新建點擊pojo類，包含點擊文章id、ip、日期屬性。
public class Click {	private Integer id;	private Integer Aid;	private String ip;	private Date clickDate;	public Integer getId() {		return id;	}	public void setId(Integer id) {		this.id = id;	}	public Integer getAid() {		return Aid;	}	public void setAid(Integer aid) {		Aid = aid;	}	public String getIp() {		return ip;	}	public void setIp(String ip) {		this.ip = ip;	}	public Date getClickDate() {		return clickDate;	}	public void setClickDate(Date clickDate) {		this.clickDate = clickDate;	}}
4、一個ip同一日期只能點擊一次，多余點擊點擊數不增加。
評論數和點擊數在博客首頁與博客首頁均有顯示
action中代碼：
public String showArticleCon() throws Exception	{		HttpServletRequest request = ServletActionContext.getRequest();		Article article = articleService.showArticleCon(id);		String ip = request.getRemoteAddr();		SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");		String stime = sdf.format(new Date());		Date clickDate = sdf.parse(stime);		if(!clickService.queryClick(id, ip, clickDate))		{			//點擊量增加			article.setHasread(article.getHasread() + 1);					}		//將更新的Article保存到數據表中		articleService.updateArticle(article);						//顯示評論		Page page = new Page();		page.setCurrentPage(this.getCurrentPage());		page.setEveryPage(2);		Result result = criticismService.pageQueryCriticism(id, page);		request.setAttribute("allCriticism", result.getList());		request.setAttribute("page", result.getPage());		request.setAttribute("article", article);		return SUCCESS;	}將評論記錄到數據庫：
public String addCriticism()	{		Map session = ActionContext.getContext().getSession();		String username = (String) session.get("username");		criticism.setUsername(username);		criticism.setAid(id);		criticism.setContent(content);		this.criticismService.addCriticism(criticism);		return SUCCESS;	}文章內容和評論顯示：
還有很多不足待改進，歡迎各位提出修改意見！！
