1.js实现关闭浏览器当前窗口
function closeWindow(){ var userAgent = navigator.userAgent; if (userAgent.indexOf("Firefox") != -1 || userAgent.indexOf("Presto") != -1) { window.location.replace("about:blank"); } else { window.opener = null; window.open("", "_self"); window.close(); } }
2.nginx 的测试,启动,停止与重启
测试:nginx -t (可检验配置文件等内容是否正确)
启动:直接点击Nginx目录下的nginx.exe 或者 cmd运行start nginx
关闭:nginx -s stop 或者 nginx -s quit (stop表示立即停止nginx,不保存相关信息 quit表示正常退出nginx,并保存相关信息)
重启:nginx -s reload
3.Restrictions.ilke与Restrictions.like的区别
前者可以忽略大小写查询 而后者类似于sql中的 like
如果是使用HQL,可以使用lower或者upper函数来实现 from User u where lower(u.username)=lower(’Mp3′)
如果使用Criteria,首先使用Restrictions创建Criterion 如果是字符串相等匹配Restrictions.eq(’username’,‘mp3′).ignoreCase() 如果是字符串模糊匹配Restrictions.ilike(’username’,‘mp3′)或者Restrictions.like(’username’,‘mp3′).ignoreCase()(摘自百度知道)
4.hibernate实现模糊查询的方法:(来源:http://newleague.iteye.com/blog/953499)
(1)第一种方式:QBC查询(Expression.like)
String name = "", info = ""; if (sub != null && sub.getSubname() != null) { name = sub.getSubname(); } if (sub != null && sub.getSubinfo() != null) { info = sub.getSubinfo(); } Criteria cr = session.createCriteria(Subject.class); cr.add(Expression.like("subname","%"+name+"%")); cr.add(Expression.like("subinfo","%"+info+"%"));
(2)第二种方式:QBC查询(Restrictions.ilike)
cr.add(Restrictions.or(Restrictions.ilike("postTitle", getKeyword(), MatchMode.ANYWHERE), Restrictions.ilike("postContent", getKeyword(), MatchMode.ANYWHERE)));
(3)第三种方式:HQL查询语句
String sql=""; sql = "from Pfapp where name like :subname "; Query query = session.createQuery(sql); query.setString("subname","%"+subnamevalue+"%");
5.使用Jsoup获取手机归属地信息
package test.data; import org.jsoup.Jsoup; import org.jsoup.nodes.Document; import org.jsoup.select.Elements; public class GetData { public static void main(String[] args) throws Exception{ String result = getLocation("18385552222"); //根据返回的文本内容,获取手机归属地信息 System.out.println(result.replace("<!-- <td></td> -->", "").replace(" ", " ")); } public static String getLocation(String phoneNum) throws Exception{ //从ip138网站请求并且获取信息 String url = "http://www.ip138.com:8080/search.asp"; //匹配返回的字符串标签 String titleCssQuery = "td.tdc2"; //传参数,action=mobile&moblie=手机号 Document document = Jsoup.connect(url).data("action", "mobile").data("mobile", phoneNum).get(); if(null == document){ return ""; } //对返回的页面内容进行指定标签的获取 Elements totalElement = document.select(titleCssQuery); String ele = totalElement.eq(1).html(); return ele; } }
