email 校验：
javascript: /^([a-zA-Z0-9_-])[email protected]([a-zA-Z0-9_-])+((.[a-zA-Z0-9_-]{2,3}){1,2})$/java: ^([a-zA-Z0-9_-])[email protected]([a-zA-Z0-9_-])+((\\.[a-zA-Z0-9_-]{2,3}){1,2})$一段小代码：
public class Demo {
public static void main(String[] args) {
System.out.println("满足逻辑的:");
System.out.println("[email protected]: " + emailFormat("[email protected]"));
System.out.println("[email protected]: " + emailFormat("[email protected]"));
System.out.println("不满足校验逻辑:");
System.out.println("[email protected]: " + emailFormat("[email protected]"));
System.out.println("[email protected]： " + emailFormat("[email protected]"));
System.out.println("[email protected],com： " + emailFormat("[email protected],com"));
System.out.println("[email protected]： " + emailFormat("[email protected]"));
System.out.println("[email protected]?q?.com： " + emailFormat("[email protected]?q?.com"));
System.out.println("[email protected]@qq.com： " + emailFormat("[email protected]@qq.com"));
System.out.println("[email protected]@139.com： " + emailFormat("[email protected]@139.com"));
System.out.println("[email protected]。com.cn： " + emailFormat("[email protected]。com.cn"));
System.out.println("[email protected])m： " + emailFormat("[email protected])m"));
System.out.println("[email protected]?￡QQ.COM： " + emailFormat("[email protected]?￡QQ.COM"));
System.out.println("[email protected]_.com.cn： " + emailFormat("[email protected]_.com.cn (严格版校验不通过)"));
System.out.println("[email protected]_163sadasdf.com.cn： " + emailFormat("[email protected]_163sadasdf.com.cn (严格版校验不通过)"));
}
public static boolean emailFormat(String email) {
String regStr = "^([a-zA-Z0-9_-])[email protected]([a-zA-Z0-9_-])+((\\.[a-zA-Z0-9_-]{2,3}){1,2})$";
boolean tag = true;
if (!email.matches(regStr)) {
tag = false;
}
return tag;
}
}
