今天修改了之前写的代码，其中有一个Java的正则类，模拟了PHP的几个函数，熟悉PHP的一看就清楚用法。支持常见的正则匹配，用法简单易懂。有需要的可以拿去，免得到处找来找去的麻烦。
正则枚举类：
public enum FILTER {
EMAIL("(?i)^[_a-z0-9\-]+([._a-z0-9\-]+)*@[a-z0-9\-]+([.a-z0-9\-]+)*(\.[a-z]{2,4})$"),
NUMBER("[+-]?\d+[.0-9]*"),
MOBILEPHONE("^(13|15|18)\d{9}$"),
MOBILE_CM("^1(34[0-8]|(3[5-9]|5[017-9]|8[278])\d)\d{7}$"),
MOBILE_CU("^1(3[0-2]|5[256]|8[56])\d{8}$"),
MOBILE_CT("^1((33|53|8[09])[0-9]|349)\d{7}$"),
PHONES("^0(10|2[0-9]|\d{3})\d{7,8}$"),
URL("(?i)^(http|https|www|ftp|)?(://)?([_a-z0-9\-].)+[_a-z0-9\-]+(\/[_a-z0-9\-])*(\/)*([_a-z0-9\-].)*([_a-z0-9\-&#?=])*$"),
CASE("^[a-zA-Z]+$"),
IPV4("(?<=(\b|\D))(((\d{1,2})|(1\d{2})|(2[0-4]\d)|(25[0-5]))\.){3}((\d{1,2})|(1\d{2})|(2[0-4]\d)|(25[0-5]))(?=(\b|\D))"),
IPV6(".*/([0-9a-f]+:[0-9a-f]+:[0-9a-f]+:[0-9a-f]+:[0-9a-f]+:[0-9a-f]+:[0-9a-f]+:[0-9a-f]+(%[a-zA-Z0-9]+)?):([0-9]+)"),
CHINESE("[\u4e00-\u9fa5]*"),
TWOBYTES("[^\x00-\xff]"),
IDCARD("IDCARD"),
CJK("\p{InCJK Unified Ideographs}"),
ISBN10("^(?:(\d{9}[0-9X])|(?:(\d{1,5})(?:\-|\s)(\d{1,7})(?:\-|\s)(\d{1,6})(?:\-|\s)([0-9X])))$"),
ISBN13("^(978|979)(?:(\d{10})|(?:(?:\-|\s)(\d{1,5})(?:\-|\s)(\d{1,7})(?:\-|\s)(\d{1,6})(?:\-|\s)([0-9])))$"),
ISEMPTY("ISEMPTY");
private String regexp;
private FILTER(String regexp) {
this.regexp = regexp;
}
public String getRegexp() {
return regexp;
}
public static boolean getIDCARD(String idcard){
return IdcardValidator.isValidatedAllIdcard(idcard);
}
public static boolean getISEMPTY(String str){
return (str == null) || (str.trim().length() < 1);
}
}里面列举了常见的正则，对于无法或不适用正则判断的情况，就调用其它类里方法进行判断.实现类如下：
import java.util.ArrayList;
import java.util.List;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
/**
* 常用验证助手
* @author 白的菜
* @date @verson
*/
public final class ValidatorHelper {
public static Boolean filter_var(final String valids,final FILTER type,String... addon){
boolean retval = false;
switch(type.name()){
case "IDCARD":
retval=FILTER.getIDCARD(valids);
break;
case "ISEMPTY":
retval=FILTER.getISEMPTY(valids);
break;
default:
retval = valids.matches(type.getRegexp());
}
return retval;
}
public static Boolean filter_var_free(final String valids,final String reg){
boolean retval = false;
retval = valids.matches(reg);
return retval;
}
public static List<String> preg_match_all(final String source, final String regex) {
List<String> result = new ArrayList<String>();
final Pattern p = Pattern.compile(regex);
Matcher matcher = p.matcher(source);
while (matcher.find()) {
result.add(matcher.group());
}
return result;
}
public static String preg_match(final String source, final String regex) {
Pattern p = Pattern.compile(regex);
Matcher matcher = p.matcher(source);
return matcher.find() ? matcher.group() : "";
}
public static String preg_replace(final String source, final String regex, final String replacement) {
Pattern p = Pattern.compile(regex);
Matcher matcher = p.matcher(source);
return matcher.find() ? source.replace(matcher.group(), replacement) : source;
}
/**
* 判断type是否基本类型,如String,Boolean,Number,Date
*/
public static Boolean basicType(Class type) {
if (type.isArray()) {// 如是数组
return basicType(type.getComponentType());// 判断元素类型
} else {
return type.isPrimitive() || type.equals(String.class) || type.equals(Boolean.class) || Number.class.isAssignableFrom(type) || java.util.Date.class.isAssignableFrom(type);
}
}
}测试如下：
out.println(ValidatorHelper.filter_var("ppmm@qq.com", FILTER.EMAIL));
out.println(ValidatorHelper.filter_var("202.255.15.238", FILTER.IPV4));
out.println(ValidatorHelper.filter_var("978-7-115-29031-6",
FILTER.ISBN13));
out.println(ValidatorHelper.filter_var("360722198808290528",
FILTER.IDCARD));
out.println(ValidatorHelper.filter_var("360722198808290527",
FILTER.IDCARD));
String emailS = "admin@qq.com,ma_hua_teng2012@163.com,mayun@alibaba.com.cn";
String emailReg = "(?i)[_a-z0-9\-]+([._a-z0-9\-]+)*@[a-z0-9\-]+([.a-z0-9\-]+)*(\.[a-z]{2,4})";
List<String> list = new ArrayList<String>();
list = ValidatorHelper.preg_match_all(emailS, emailReg);
for (String string : list) {
out.println(string);
}
