java AES加密

public static byte[] encrypt(String content, String password) {
        try {
            byte[] enCodeFormat = password.getBytes();
            SecretKeySpec key = new SecretKeySpec(enCodeFormat, "AES");
            Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
            byte[] byteContent = content.getBytes("utf-8");
            cipher.init(Cipher.ENCRYPT_MODE, key);
            byte[] result = cipher.doFinal(byteContent);
            return result; 
        } catch (Exception e) {
            // LOG.error(" aes encrypt error: [{}]", password,e);
            e.printStackTrace();
            return null;
        }
    }

// aes 二进制转成base64
import org.apache.commons.codec.binary.Base64;
String s = new String(Base64.encodeBase64(encryptBytes));
// s 为加密后的base64编码
