Java使用 使用AES加解密算法，加密模式：ECB，填充：Zeropadding

public class diaoduService {

        //Java中不支持Zeropadding填充，使用NoPadding处理，结果都是一样的
    private static final String DEFAULT_CIPHER_ALGORITHM = "AES/ECB/NoPadding";// 默认的加密算法

    /**
     * AES 加密操作
     *
     * @param content 待加密内容
     * @param password 加密密码
     * @return
     */
    public  String encrypt(String content, String password) {
        try {
            Cipher cipher = Cipher.getInstance(DEFAULT_CIPHER_ALGORITHM);// 创建密码器
            int blockSize = cipher.getBlockSize();
            byte[] byteContent = content.getBytes();
            int plaintextLength = byteContent.length;
            if (plaintextLength % blockSize != 0) {
                plaintextLength = plaintextLength + (blockSize - (plaintextLength % blockSize));
            }
            byte[] plaintext = new byte[plaintextLength];
            System.arraycopy(byteContent, 0, plaintext, 0, byteContent.length);
            cipher.init
