麻烦大神把这段改写成java，两者能互通，在线等~

Question

<?php
/**

• 利用mcrypt做AES加密解密 */

abstract class AES{
/**
* 算法,另外还有192和256两种长度
/
const CIPHER = MCRYPT_RIJNDAEL_128;
/*
* 模式
*/
const MODE = MCRYPT_MODE_ECB;

/**
 * 加密
 * @param string $key    密钥
 * @param string $str    需加密的字符串
 * @return type
 */
static public function encode( $key, $str ){
    $iv = mcrypt_create_iv(mcrypt_get_iv_size(self::CIPHER,self::MODE),MCRYPT_RAND);

    return mcrypt_encrypt(self::CIPHER, $key, $str, self::MODE, $iv);
}

/**
 * 解密
 * @param type $key
 * @param type $str
 * @return type
 */
static public function decode( $key, $str ){
    $iv = mcrypt_create_iv(mcrypt_get_iv_size(self::CIPHER,self::MODE),MCRYPT_RAND);
    return mcrypt_decrypt(self::CIPHER, $key, $str, self::MODE, $iv);
}

}
?>

自己写了个java的，但是加密出来，前面一段相同，后面一段不同
public static String encrypt(String input, String key) throws Exception {
byte[] crypted = null;
try {
SecretKeySpec skey = new SecretKeySpec(key.getBytes(), "AES");

        Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
        cipher.init(Cipher.ENCRYPT_MODE, skey);
        crypted = cipher.doFinal(input.getBytes());
    } catch (Exception e) {
        System.out.println(e.toString());
    }
    return new String(byte2hex(crypted));
}
