Java获取字符串Md5值

package org.example;
import java.io.UnsupportedEncodingException;
import java.nio.charset.StandardCharsets;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
public class MD5Test {
    public static String getMd5(String text) throws NoSuchAlgorithmException, UnsupportedEncodingException {
        MessageDigest md5 = MessageDigest.getInstance("MD5");
        byte[] bytes = md5.digest(text.getBytes(StandardCharsets.UTF_8));
        StringBuilder builder = new StringBuilder();
        for (byte aByte : bytes) {
            builder.append(Integer.toHexString((0x000000FF & aByte) | 0xFFFFFF00).substring(6));
        }
        return builder.toString();
    }
    public static void main(String[] args) throws NoSuchAlgorithmException, UnsupportedEncodingException {
        String str = "hello md5 你好";
        System.out.println(getMd5(str));
        //    fca0127f57c8528791332645b8105bd8
