java后端实现对含有特殊字符校验

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Demo {
    public static void main(String[] args) {
        String str="aaaa";
        boolean rs=isSpecialChar(str);
        System.out.println(rs);
    }


    public static boolean isSpecialChar(String str) {
        String regEx = "[ _`~!@#$%^&*()+=|{}':;',\\[\\].<>/?~！@#￥%……&*（）——+|{}【】‘；：”“’。，、？]|\n|\r|\t";
        Pattern p = Pattern.compile(regEx);
        Matcher m = p.matcher(str);
        return m.find();
    }
