正则表达式

目前项目中用到的正则表达式

import java.util.regex.Pattern;

public class RegexUtil {

    //默认数字
    public static String NUM = "([0-9]*)|([0-9]*\\.[0-9]*)|-([0-9]*)|-([0-9]*\\.[0-9]*)";

    //正数
    public static String PLUS_NUM = "([0-9]*)|([0-9]*\\.[0-9]*)";

    //数字总长度为15位，最多2位小数
    public static String NUM_15_2 = "([1-9]\\d{0,12})|([1-9]\\d{0,12}\\.\\d{1,2})";

    public static boolean match(String regex, Object input){
        if (input == null) {
            return false;
        }
        return Pattern.matches(regex, input.toString());
    }

    public static boolean isNumeric(Object str) {
        if (str == null) {
            return false;
        }

        Boolean isMatch = Pattern.matches(NUM, str.toString());
        if (!isMatch) {
            return false;
        }
        if (str.toString().contains(",")) {
            return false;
        }
        return true;
    }

}
