这篇文章主要介绍了正则表达式实现字符的模糊匹配功能,结合具体java实例形式分析了针对字符串的模糊匹配查询相关实现技巧,需要的朋友可以参考下

本文实例讲述了正则表达式实现字符的模糊匹配功能。分享给大家供大家参考,具体如下:

package com.cn.util;
import java.util.regex.Pattern;
/**
 * 正则表达式 工具类
 * 
 * @author lifangyu
 */
public class RegexUtil {
  /*
   * IP地址的匹配标达式 ( // \\d{1,3}) // :\d // 0~9数字,{1,3} // 至少一位,最多三位)
   */
  private static String regex_IP = "^(121.15.215.(\\d{1,3}))$";
  /*
   * 字符串 模糊匹配 :^(.*张三.*name.*)$ ; 等值匹配 ^(张三)$
   */
  private static String regex_containStr = "^(.*张三.*name.*)$";
  /*
   * 字符不包含特定字符串的表达式
   */
  private static String regex_notcontainStr = "^(?!.*(转发)).*$";// 不包含特定字符串的表达式
  public static void main(String[] args) {
    System.out.println(StringMatchRule("这个邮件 是转发的!", regex_notcontainStr));
  }
  public static boolean StringMatchRule(String souce, String regex) {
    boolean result = false;
    if (regex != null && souce != null) {
      result = Pattern.matches(regex, souce);
    }
    return result;
  }
}
