1、将时间戳转换成日期

function add0(m){return m<10?'0'+m:m }
function format(shijianchuo)
{
//shijianchuo是整数，否则要parseInt转换
var time = new Date(shijianchuo);
var y = time.getFullYear();
var m = time.getMonth()+1;
var d = time.getDate();
var h = time.getHours();
var mm = time.getMinutes();
var s = time.getSeconds();
return y+'-'+add0(m)+'-'+add0(d)+' '+add0(h)+':'+add0(mm)+':'+add0(s);
}

这里要注意time.getMonth()系统默认一月为从0开始，故要将其加一才为实际月份

2、过滤html标签

package com.zz.xd.util;

import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class MyUtil {
	
	 public static String delHTMLTag(String htmlStr){ 
	        String regEx_script="<script[^>]*?>[\\s\\S]*?<\\/script>"; //定义script的正则表达式 
	        String regEx_style="<style[^>]*?>[\\s\\S]*?<\\/style>"; //定义style的正则表达式 
	        String regEx_html="<[^>]+>"; //定义HTML标签的正则表达式 
	         
	        Pattern p_script=Pattern.compile(regEx_script,Pattern.CASE_INSENSITIVE); 
	        Matcher m_script=p_script.matcher(htmlStr); 
	        htmlStr=m_script.replaceAll(""); //过滤script标签 
	         
	        Pattern p_style=Pattern.compile(regEx_style,Pattern.CASE_INSENSITIVE); 
	        Matcher m_style=p_style.matcher(htmlStr); 
	        htmlStr=m_style.replaceAll(""); //过滤style标签 
	         
	        Pattern p_html=Pattern.compile(regEx_html,Pattern.CASE_INSENSITIVE); 
	        Matcher m_html=p_html.matcher(htmlStr); 
	        htmlStr=m_html.replaceAll(""); //过滤html标签 

	        return htmlStr.trim(); //返回文本字符串 
	    } 

}

注意要先过滤在剪切拼接，不然会导致剪切到html代码使得过滤方法无法正常使用！

controller代码：

@RequestMapping("find/{id}")
	public Map getDetail(@PathVariable("id") Long id){
		Detail d=detailRepository.findOne(id);
		Map m=new HashMap();
		List<Comment> ls=commentRepository.findByDetailid(id);
		m.put("detail", d);
		m.put("comments", ls);
		
		return m;

js代码：

$(document).ready(
				function() {
					var url = decodeURI(location.href);
					var result = url.split("?")[1];
					$.get(
									"/springbootdemo/detail/find/" + result,
									function(data) {
										console.log(data);
										$("#titlecontent").text(data.detail.title);
										$("#bodycontent").html(
												data.detail.content);
										var ccontext = "";
										for (i = 0; i < data.comments.length; i++) {
											var date=new Date(data.comments[i].createtime);
											ccontext = ccontext
													+ '<li class="comment even thread-even depth-1" id="li-comment-">									<div id="comment-969" class="comment_body contents">										<div class="profile">											<a href=""><img src="/springbootdemo/demo/index/statics/images/9cc50a9e422fb1c89aebafeb959cef7a.jpg" class="gravatar" alt="小布丁"></a>										</div>										<div class="main shadow">											<div class="commentinfo">												<section class="commeta">													<div class="shang">														<h4 class="author"><a href="" target="_blank"><img src="/springbootdemo/demo/index/statics/images/9cc50a9e422fb1c89aebafeb959cef7a.jpg" class="gravatarsmall" alt="小布丁">'
													+ data.comments[i].authorid;
											ccontext = ccontext
													+ '</a></h4>													</div>												</section>											</div>											<div class="body">												<p>'
													+ data.comments[i].content;
											ccontext = ccontext
													+ '</p>											</div>											<div class="xia info">												<span><time >'
													+ date.getFullYear()+'年'+(date.getMonth()+1)+'月'+date.getDate()+'日';
											ccontext = ccontext
													+ '</time></span>												<span><a rel=“nofollow” class=“comment-reply-link” href="" onclick=“return addComment.moveForm( "comment-969", "969", "respond", "1202" )” aria-label=“回复给小布丁”>回复</a></span>											</div>										</div>									</div>								</li>';

										}
										$("#commentwrap").html(ccontext);
									});
				});

效果图如下：
