手机号的正则校验，前台校验或者后台校验

<div class="col-sm-8">
		<#form:input path="contactTelephone" maxlength="11" class="form-control" onChange="checkPhoneNumber()"/>
		<span class="help-inline" id="phone_error" style="display:none;" ><font color="red">*</font> <span id="error_msg"> </span></span>
	</div>

	//方式一：html页面校验
	function checkPhoneNumber() {
		var phoneInput = $("#contactTelephone").val();
		if(phoneInput.trim().length>0){
			var phoneReg = /^(13[0-9]{9})|(18[0-9]{9})|(14[0-9]{9})|(17[0-9]{9})|(15[0-9]{9})$/;
			if (phoneReg.test(phoneInput)) {
				$("#phone_error").attr("style","display:none;");
				return true;
			} else {
				$("#phone_error").attr("style","display:block;");
				$("#error_msg").text( '手机号码输入有误！');
				return false;
			}
		}else{
			$("#phone_error").attr("style","display:none;");
		}
	}

//方式二：controller中校验
	String phoneReg = "^((13[0-9])|(14[5|7])|(15([0-3]|[5-9]))|(17[013678])|(18[0,5-9]))\\d{8}$";
	Pattern pattern = Pattern.compile(phoneReg);
	Matcher matcher = pattern.matcher("your number");
	boolean isMatch = matcher.matches();
	if(!isMatch){
		return renderResult(Global.FALSE, text("手机号输入不正确!"));
	}
	
	//或者
	String phoneNumber = salesArea.getContactTelephone().trim();
	if(!StringUtils.isBlank(phoneNumber)){
		boolean isMatch = phoneNumber.matches(Constants.PHONE_REG);
		if(!isMatch){
			return renderResult(Global.FALSE, text("手机号输入不正确!"));
		}
	}
