对表单的Email地址进行验证

使用Java正则表达式来进行EMail地址的合法性判断

 

主要代码部分：

 

Pattern pattern = Pattern.compile(RegExpression.REG_email);
        Matcher m = pattern.matcher(email);
        if (!m.find()) {
            errors.rejectValue("email", "register.error.email", null, "地址不合法!");
        }

 

将Email的匹配表达式作为一个常量放在类RegException中

package com.demo.spring.util;

public class RegExpression {
    public final static String REG_int = "^\\d*$";
    public final static String REG_float = "^\\d+(\\.\\d+)?$";
    public final static String REG_date = "^[\\d]{4}([-][\\d]{2}){2}$";
    public final static String REG_time = "^[\\d]{4}([-][\\d]{2}){2}([ ][12]{1}[\\d]{1}([:][123456]{1}[\\d]{1}){2}){1}$";
    public final static String REG_datetime = "^[\\d]{4}([-][\\d]{2}){2}([ ][12]{1}[\\d]{1}([:][123456]{1}[\\d]{1}){2}){1}$";
    public final static String REG_email = "^[\\w\\d]+@[\\w\\d]+(\\.[\\w\\d]+)+$";
    public final static String REG_phone = "^(\\d+[-]){0,2}\\d+$";
    public final static String REG_mobile = "^[1]\\d{10}$";
    public final static String REG_postcode = "^\\d{6}$";
//    public final static String REG_url = "/^[\\w]+[:][/]{2}([\\w]+\\.)+([\\w]+[/])+[\\w]+[.][\\w]+$/";

    public final static String REG_url = "^[\\w]+[:][/]{2}([\\w]+\\.)+([\\w]+[/])+[\\w\\.]*$";

};
