在从前端获取手机号后，首先需要校验手机号是否有效

如下：

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12

public static boolean isChinaMobile(String mobile) {
if (mobile == null)
return false;
String PATTERN = "^((13[0-9])|(14[0,1,4-9])|(15[0-3,5-9])|(16[2,5,6,7])|(17[0-8])|(18[0-9])|(19[0-3,5-9]))\\\\d{8}$";
// Set the email pattern string
Pattern p = Pattern.compile(PATTERN);

    // Match the given string with the pattern
    Matcher m = p.matcher(mobile);

    // check whether match is found
    return m.matches();
