配置加解密Bean

@Configuration
public class EncryptionPropertyConfig {
    @Bean(name = "encryptablePropertyResolver")
    public EncryptablePropertyResolver encryptablePropertyResolver() {
        return new EncryptionPropertyResolver();
    }
    class EncryptionPropertyResolver implements EncryptablePropertyResolver {
        @Override
        public String resolvePropertyValue(String value) {
            if (StringUtils.isBlank(value)) {
                return value;
            }
            // 值以DES@開頭的均為DES加密,需要解密
            if (value.startsWith("DES@")) {
                return resolveDESValue(value.substring(4));
            }
            // 不需要解密的值直接返回
            return value;
        }
        private String resolveDESValue(String value) {
            // 自定義DES密文解密
            return DesUtil.decrypt(value, DesUtil.KEY);
        }
    }
}

編寫加解密工具類

之前在github上找到的工具類,，抱歉之前沒留下原地址,。

@NoArgsConstructor(access = AccessLevel.PRIVATE)
public class DesUtil {
    /** 默認(rèn)key */
    public final static String KEY = "ScAKC0XhadTHT3Al0QIDAQAB";
    /**
     * DES加密
     *
     *
     * @param data
     * 				待加密字符串
     * @param key
     * 				校驗(yàn)位
     * @return
     */
    public static String encrypt(String data,String key) {
        String encryptedData = null;
        try {
            // DES算法要求有一個(gè)可信任的隨機(jī)數(shù)源
            SecureRandom sr = new SecureRandom();
            DESKeySpec deskey = new DESKeySpec(key.getBytes());
            // 創(chuàng)建一個(gè)密匙工廠,，然后用它把DESKeySpec轉(zhuǎn)換成一個(gè)SecretKey對象
            SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES");
            SecretKey secretKey = keyFactory.generateSecret(deskey);
            // 加密對象
            Cipher cipher = Cipher.getInstance("DES");
            cipher.init(Cipher.ENCRYPT_MODE, secretKey, sr);

    public static String decrypt(String cryptData,String key) {
        String decryptedData = null;
        try {

            SecureRandom sr = new SecureRandom();
            DESKeySpec deskey = new DESKeySpec(key.getBytes());
            // 創(chuàng)建一個(gè)密匙工廠,，然后用它把DESKeySpec轉(zhuǎn)換成一個(gè)SecretKey對象
            SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES");
            SecretKey secretKey = keyFactory.generateSecret(deskey);
            // 解密對象
            Cipher cipher = Cipher.getInstance("DES");
            cipher.init(Cipher.DECRYPT_MODE, secretKey, sr);
            // 把字符串解碼為字節(jié)數(shù)組，并解密
            decryptedData = new String(cipher.doFinal(new sun.misc.BASE64Decoder().decodeBuffer(cryptData)));
        } catch (Exception e) {
            throw new RuntimeException("解密錯(cuò)誤,，錯(cuò)誤信息：", e);
        }
        return decryptedData;
    }
    public static void main(String[] args) {
        System.out.println("url::"+encrypt("jdbc:oracle:thin:@127.0.0.1:1521:xe",KEY));
        System.out.println("username::"+encrypt("admin",KEY));
        System.out.println("password::"+encrypt("admin",KEY));
    }
}

工具類中的main方法執(zhí)行結(jié)果為：

修改properties文件
