反射给传参加密

通过反射给参数进行AES算法加密  这里是部分参数加密  

最后效果

 

 AES工具类

public class AESUtil {

    private static final String KEY_ALGORITHM = "AES";
    private static final String DEFAULT_CIPHER_ALGORITHM = "AES/ECB/PKCS5Padding";//默认的加密算

    /**
     * AES 加密操作
     *
     * @param content
     * @param password
     * @return
     */
    public static String encrypt(String content, String password) {
        try {
            Cipher cipher = Cipher.getInstance(DEFAULT_CIPHER_ALGORITHM);

            byte[] byteContent = content.getBytes("utf-8");

            cipher.init(Cipher.ENCRYPT_MODE, getSecretKey(password));// 初始化为加密模式的密码器

            byte[] result = cipher.doFinal(byteContent);// 加密

            return Base64.getEncoder().encodeToString(result);//通过Base64转码返回
        } catch (Exception ex) {
            Logger.getLogger(AESUtil.class.getName()).log(Level.SEVERE, null, ex);
        }

        return null;
    }

    /**
     * AES 解密操作
     *
     * @param content
     * @param password
     * @return
     */
    public static String decrypt(String content, String password) {

        try {
            Cipher cipher = Cipher.getInstance(DEFAULT_CIPHER_ALGORITHM);

            cipher.init(Cipher.DECRYPT_MODE, getSecretKey(password));

            //执行操作
            byte[] result = cipher.doFinal(Base64.getDecoder().decode(content));

            return new String(result, "utf-8");
        } catch (Exception ex) {
//            log.error(ex.getMessage(),ex);
        }

        return null;
    }
}

实体类

@TableName(value ="vip_card",autoResultMap = true)
@Data
public class VipCard implements Serializable {
    /**
     * id
     */
    @TableId(type = IdType.AUTO)
    private Integer id;

    /**
     * 卡号
     */
    @TableField(typeHandler = AESHandler.class)
    private String cardNo;

    /**
     * 用户名
     */
    @TableField(typeHandler = AESHandler.class)
    private String name;

    /**
     * 性别
     */
    private Integer gender;

    /**
     * 年龄
     */
    private Integer age;

    /**
     * 邮箱
     */
    @TableField(typeHandler = AESHandler.class)
    private String email;

    /**
     * 身份证号
     */
    @TableField(typeHandler = AESHandler.class)
    private String idNumber;

    /**
     * 地址
     */
    @TableField(typeHandler = AESHandler.class)
    private String address;

    /**
     * 手机号
     */
    @TableField(typeHandler = AESHandler.class)
    private String phoneNumber;
}

测试类

public class Test {
    public static void main(String[] args) {

        String password = "VtW************==";

        VipCard vipCard2 = new VipCard();
        //所有属性 遍历加密

                        field.set(vipCard2, value);
                    } catch (IllegalAccessException e) {
                        System.out.println("非加密字段反射异常");
