写一套springboot接口加解密代码

好的，这里是示例代码。请注意，为了更好地保护您的数据，此代码使用了AES对称加密和Base64编码，同时保证了接口的高可用性和易用性。

import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;
import org.apache.tomcat.util.codec.binary.Base64;

@Service
public class EncryptionService {
    private static final String AES_ALGORITHM = "AES";
    private static final String SECRET_KEY = "0123456789123456";

    private static SecretKeySpec getKey() {
        byte[] key = SECRET_KEY.getBytes();
        return new SecretKeySpec(key, AES_ALGORITHM);
    }

    public static String encrypt(String data) throws Exception {
        Cipher cipher = Cipher.getInstance(AES_ALGORITHM);
        cipher.init(Cipher.ENCRYPT_MODE, getKey());
        byte[] encryptedBytes = cipher.doFinal(data.getBytes());
        return Base64.encodeBase64String(encryptedBytes);
    }

    public static String decrypt(String encryptedData) throws Exception {
        Cipher cipher = Cipher.getInstance(AES_ALGORITHM);
        cipher.init(Cipher.DECRYPT_MODE, getKey());
        byte[] decodedBytes = Base64.decodeBase64(encryptedData);
        byte[] decryptedBytes = cipher.doFinal(decodedBytes);
        return new String(decryptedBytes);
    }
}

@RestController
public class MyController {
    @GetMapping("/encrypt")
    public String encrypt(@RequestParam String data) throws Exception {
        return EncryptionService.encrypt(data);
    }

    @GetMapping("/decrypt")
    public String decrypt(@RequestParam String encryptedData) throws Exception {
        return EncryptionService.decrypt(encryptedData);
    }
}

以上代码分别提供了两个GET接口，简单地实现了加解密功能。通过SpringBoot的@RestController注解使其易于使用。

请注意：为了确保数据安全，请将SECRET_KEY替换为真正的密钥，并在生产环境中使用HTTPS来保护数据传输过程。
