CryptoJS前端加密和后台Java解密

后端加密和解密：

import org.springframework.util.StringUtils;
import java.nio.charset.StandardCharsets;
import java.util.Base64;

public class EncryptUtil {
          
   

//这个密钥需要是16位
public static final String KEY_DES = "aaaaaaaabbbbbbbb";

public static void main(String[] args) throws Exception {
          
   
		String old = "12345678";
		String target ="UxoeqTwLRGW9HtZEtJOcug==";

//解密
		System.out.println(EncryptUtil.aesDecryptForFront(target,EncryptUtil.KEY_DES));
	
	//加密
		System.out.println(EncryptUtil.aesEncryptForFront(old,EncryptUtil.KEY_DES));

	}
