正则常用后台验证

验证用户为中文：

     String passUserNO = serialLog.getBillKey().trim();
		Pattern chinaP = Pattern.compile("^[\u4e00-\u9fa5]+");
		Matcher chinaM = chinaP.matcher(passUserNO);
		boolean chinaKey = chinaM.matches();
		if(chinaKey==true){
			addActionError("用户总户号不能为中文！");
			return businessDetails();
		}

//正则匹配 (里的)

public static void test(){
		 Pattern pattern1 = Pattern.compile("\\(\\w+\\)");
         Matcher matcher = pattern1.matcher("aaaa(bbb)aaaaaaaaa(bb)aaaaaa");
         while(matcher.find()){
            String str = matcher.group();
            System.out.println("str:"+str);
     }
