判断类
package config; import java.util.regex.Matcher; import java.util.regex.Pattern; public class CheckMobile { private CheckMobile() { } // \b 是单词边界(连着的两个(字母字符 与 非字母字符) 之间的逻辑上的间隔), // 字符串在编译时会被转码一次,所以是 "\\b" // \B 是单词内部逻辑间隔(连着的两个字母字符之间的逻辑上的间隔) private static String phoneReg = "\\b(ip(hone|od)|android|opera m(ob|in)i" +"|windows (phone|ce)|blackberry" +"|s(ymbian|eries60|amsung)|p(laybook|alm|rofile/midp" +"|laystation portable)|nokia|fennec|htc[-_]" +"|mobile|up.browser|[1-4][0-9]{2}x[1-4][0-9]{2})\\b"; private static String tableReg = "\\b(ipad|tablet|(Nexus 7)|up.browser" +"|[1-4][0-9]{2}x[1-4][0-9]{2})\\b"; //移动设备正则匹配:手机端、平板 private static Pattern phonePat = Pattern.compile(phoneReg, Pattern.CASE_INSENSITIVE); private static Pattern tablePat = Pattern.compile(tableReg, Pattern.CASE_INSENSITIVE); /** * 检测是否是移动设备访问 * @param userAgent 浏览器标识 * @return true:移动设备接入,false:pc端接入 */ public static boolean check(String userAgent){ if(null == userAgent){ userAgent = ""; } userAgent = userAgent.toLowerCase(); // 匹配 Matcher matcherPhone = phonePat.matcher(userAgent); Matcher matcherTable = tablePat.matcher(userAgent); return matcherPhone.find() || matcherTable.find(); } }
调用点
private static boolean isFromMobile(HttpServletRequest request, HttpSession session) { //检查是否已经记录访问方式(移动端或pc端) boolean isFromMobile = false; if (null == session.getAttribute("ua")) { //获取ua,用来判断是否为移动端访问 String userAgent = request.getHeader("USER-AGENT"); isFromMobile = CheckMobile.check(userAgent); //判断是否为移动端访问 if (isFromMobile) { session.setAttribute("ua", "mobile"); } else { session.setAttribute("ua", "pc"); } } else { isFromMobile = "mobile".equals(session.getAttribute("ua")); } return isFromMobile; }
