问题：

使用Cloud Firestore时出现Micronaut本机映像gRPC错误

张浩阔
2023-03-14

我有一个基本的Micronaut应用程序，我正在构建一个本机映像。我正在用这些参数构建它：

  native-image \
  --no-server \
  -H:+TraceClassInitialization \
  -H:+ReportExceptionStackTraces \
  --enable-url-protocols=http,https \
  --enable-all-security-services \
  --report-unsupported-elements-at-runtime \
  --no-fallback \
  -H:ConfigurationFileDirectories=/home/app/sample-app/agent-config-dir \
  --report-unsupported-elements-at-runtime \
  --initialize-at-build-time=org.conscrypt,com.fasterxml.jackson,javax,org.slf4j \
  -jar myapp.jar

映像构建得很好,我能够启动它,但是当尝试访问Firestore时,我得到了以下异常：

Message: Unsupported method of Unsafe

在这一点上，我对Micronaut和GraalVM都很陌生，所以我肯定我忽略了一些简单的东西，但是我没有找到关于这个特定错误的很多东西，而且我找到的东西也没有解决我的问题。

我正在使用Micronaut2.0.1并使用maven-shade-plugin构建一个fatJar，我随后正在运行本机映像生成。

我的Firestore配置非常简单，看起来是这样的：

@Factory
public class FirestoreConfig {

    private static final byte[] SVC_KEY = {123, 10, 32, .......};

    @Bean
    public Firestore db() throws Exception {
        InputStream serviceAccount = new ByteArrayInputStream(SVC_KEY);
        GoogleCredentials credentials = GoogleCredentials.fromStream(serviceAccount);
        FirebaseOptions options = new FirebaseOptions.Builder()
                .setCredentials(credentials)
                .build();
        FirebaseApp.initializeApp(options);
        return FirestoreClient.getFirestore();
    }

}

然后是插入此配置的相关位：

@Slf4j
@Singleton
public class MailingListsApiServiceImpl extends MailingListsApiService {
    private final TokenGenerator tokenGenerator;
    private final Firestore db;
    private final ObjectMapper objectMapper;

    @Inject
    public MailingListsApiServiceImpl(
                                      TokenGenerator tokenGenerator,
                                      Firestore db,
                                      ObjectMapper objectMapper) {
        this.tokenGenerator = tokenGenerator;
        this.db = db;
        this.objectMapper = objectMapper;
    }

<dependency>
  <groupId>com.google.firebase</groupId>
  <artifactId>firebase-admin</artifactId>
  <version>6.15.0</version>
</dependency>

如果我删除了firebase-admin依赖项并注释掉了Firestore的用法，那么我的请求确实得到了正确的处理，所以它似乎肯定与它和GRPC有关。

如有任何帮助，我们将不胜感激！

它似乎与这个有关https://github.com/oracle/graal/issues/2694

他们已经为netty解决了类似的问题，但可能需要为您的库提供额外的PR https://github.com/netty/netty/pull/10428/commits/b18122834e3688cda6edc64af694cfb06ac6b0d
