web学习之博客小项目（实现点击数和评论数的显示）

设计思路：

1、评论数和点击数都是文章的属性之一，在文章pojo类添加这两个属性。

	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、新建一个评论pojo类，包含评论内容，评论用户名，评论文章id属性。
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、新建点击pojo类，包含点击文章id、ip、日期属性。
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、一个ip同一日期只能点击一次，多余点击点击数不增加。
评论数和点击数在博客首页与博客首页均有显示
action中代码：
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))		{			//点击量增加			article.setHasread(article.getHasread() + 1);					}		//将更新的Article保存到数据表中		articleService.updateArticle(article);						//显示评论		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;	}将评论记录到数据库：
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;	}文章内容和评论显示：
还有很多不足待改进，欢迎各位提出修改意见！！
