我有一个基本的 Micronaut 应用程序，我正在将其构建为本机映像。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
图像构建良好，我可以启动它，但是在尝试访问 Firestore 时，我得到了这个异常：

在这一点上，我对 Micronaut 和 GraalVM 都很陌生，所以我确信我忽略了一些简单的东西，但是我无法找到关于这个特定错误的太多信息，而且我确实找到的东西并没有解决我的问题。
我正在使用 Micronaut 2.0.1 并使用 maven-shade-plugin 构建一个 fatJar，然后我正在针对它运行本机图像生成。
我的 Firestore 配置非常简单，如下所示：
@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();
}
}
然后是我注入此配置的相关位：
@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;
}
pom.xml 中的 Firebase 依赖项
<dependency>
<groupId>com.google.firebase</groupId>
<artifactId>firebase-admin</artifactId>
<version>6.15.0</version>
</dependency>
如果我删除 firebase-admin 依赖项并注释掉 Firestore 的用法，那么我的请求确实会得到正确处理，所以它肯定似乎与那个和 gRPC 有关。
任何帮助将不胜感激！
