java - Google Cloud KMS java.lang.NoSuchMethodError:com.google.common.base.Preconditions.checkArgument(ZLjava/lang/String; CLjava/lang/Object;)V

Question

我正在为KMS使用Java客户端库。 KeyManagementServiceClient.create()方法shown here引发上述异常。

Guava 依赖项看起来还不错-27.1-jre

public String encrypt(String plaintext) throws IOException {
        byte[] ciphertext = encrypt(PROJECT_ID, LOCATION_ID, KEYRING_ID, KEY_ID, plaintext.getBytes());
        return ciphertext.toString();
    }


    /**
     * Encrypts the given plaintext using the specified crypto key.
     */
    private static byte[] encrypt(
            String projectId, String locationId, String keyRingId, String cryptoKeyId, byte[] plaintext)
            throws IOException {

        // Create the KeyManagementServiceClient using try-with-resources to manage client cleanup.
        try (KeyManagementServiceClient client = KeyManagementServiceClient.create()) {

            // The resource name of the cryptoKey
            String resourceName = CryptoKeyName.format(projectId, locationId, keyRingId, cryptoKeyId);

            // Encrypt the plaintext with Cloud KMS.
            EncryptResponse response = client.encrypt(resourceName, ByteString.copyFrom(plaintext));

            // Extract the ciphertext from the response.
            return response.getCiphertext().toByteArray();
        }
    }

我希望它返回编码后的字符串，因为命令行指令在相同的项目设置和配置下可以正常工作。

第三方图书馆的问题:

  java.lang.NoSuchMethodError:   com.google.common.base.Preconditions.checkArgument(ZLjava/lang/String;CLjava/lang/Object;)V

让我们尝试看看 Guava 的依赖性。对我来说，已通过更新 Guava 解决了它:

 <dependency>
    <groupId>com.google.guava</groupId>
    <artifactId>guava</artifactId>
    <version>21.0</version>
</dependency>
