我正在尝试使用 GraalVM 构建 Spring Boot 应用程序的本机映像，但我遇到了与
InaccessibleObjectExceptionjava.util.Collections$SetFromMap当我将

这表明应用程序正在尝试通过反射访问内部类，而该反射被 Java 模块系统阻止。
在构建时添加
--add-opens在我的
pom.xml<buildArgs>
<buildArg>--add-opens=java.base/java.util=ALL-UNNAMED</buildArg>
</buildArgs>
在运行时添加
--add-opens更新了构建参数以将
--add-opens<buildArgs>
<buildArg>-H:AdditionalRuntimeOptions=--add-opens=java.base/java.util=ALL-UNNAMED</buildArg>
</buildArgs>
注册反射提示：
在我的
RuntimeHints.javahints.reflection().registerType(
TypeReference.of("java.util.Collections$SetFromMap"),
builder -> builder.withMembers(MemberCategory.values())
);
使用反射配置文件：
创建了具有必要配置的
reflect-config.json尽管进行了这些尝试，错误仍然存在。
附加信息：
java.util.Collections$SetFromMap任何指导或建议将不胜感激，特别是那些具有 GraalVM 经验或在本机映像中使用 Java 模块系统的人。
重大更改是添加 EclipseStore。如果我从 Spring Initializer 下载一个新项目并添加我的控制器，它可以编译为本机映像并运行。当我添加EclipseStore后，运行本机映像时就会出现错误。我上面尝试过的似乎都没有改变结果。
public class EclipseAccountAdapter {
private final EmbeddedStorageManager storageManager;
private static final Logger log = LoggerFactory.getLogger(EclipseAccountAdapter.class);
private final ApplicationContext context;
public EclipseAccountAdapter(EmbeddedStorageManager storageManager, ApplicationContext context) {
this.storageManager = storageManager;
this.context = context;
initializeRoot();
}
private void initializeRoot() {
if (storageManager.root() == null) {
log.info("Initializing root.");
storageManager.setRoot(new DataRoot());
storageManager.storeRoot();
}
}
@Write
public int save(Account account, StorerType storerType) {
getRoot().accounts().add(account);
store(getRoot().accounts().usernameToAccount(), storerType);
return getRoot().accounts().all().size();
}
@Read
public List<Account> findAll() {
return new ArrayList<>(getRoot().accounts().all());
}
private DataRoot getRoot() {
return (DataRoot) storageManager.root();
}
private void store(final Object object, StorerType storerType) {
try {
switch (storerType) {
case LAZY: {
Storer lazyStorer = storageManager.createLazyStorer();
lazyStorer.store(object);
lazyStorer.commit();
break;
}
case EAGER: {
Storer eagerStorer = storageManager.createEagerStorer();
eagerStorer.store(object);
eagerStorer.commit();
}
default:
storageManager.store(object);
}
} catch (final Throwable t) {
onStorageFailure(t);
}
}
private void onStorageFailure(final Throwable t) {
if (storageManager != null && storageManager.isRunning()) {
try {
log.error("Storage error! Shutting down storage...", t);
SpringApplication.exit(context, () -> 0);
} catch (final Throwable throwable) {
log.error(throwable.getMessage(), throwable);
}
}
DataRoot root = getRoot();
if (root != null) {
root.clear();
}
}
}

注意：我已经查看了类似的问题和文档，但尚未找到有效的解决方案。如果有人遇到类似的问题或知道如何解决此问题，您的帮助将是非常宝贵的。
您面临的问题并非来自 EclipseStore，而是实际上来自 Eclipse 序列化器。
您面临两种类型的问题：允许深度反思性访问
Collections.SetFromMap#m您的尝试 1 应该已经解决了反射访问的问题：
<buildArgs>
<buildArg>--add-opens=java.base/java.util=ALL-UNNAMED</buildArg>
</buildArgs>
对于反射提示，您可以使用代理（您已经尝试过）。由于您已经有了测试，因此您可以使用
-agentlib:native-image-agent=config-output-dir=/path/to/your/suggested/agent/outputmaven-surefire-pluginmvn test<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>3.5.0</version>
<configuration>
<!-- TODO replace the path with the actual path you want -->
<argLine>--add-opens java.base/java.util=ALL-UNNAMED -agentlib:native-image-agent=config-output-dir=/path/to/your/suggested/agent/output</argLine>
<forkCount>1</forkCount>
</configuration>
</plugin>
这应该创建目录
/path/to/your/suggested/agent/outputreflect-config.jsonpom.xml<profile>假设您将该文件复制到
native-image-config/reflect-config.json-H:ReflectionConfigurationFiles=native-image-config/reflect-config.jsonnative-image<plugin>
<groupId>org.graalvm.buildtools</groupId>
<artifactId>native-maven-plugin</artifactId>

<buildArg>-H:ReflectionConfigurationFiles=native-image-config/reflect-config.json</buildArg>
</buildArgs>
</configuration>
</plugin>
为了使库与本机映像兼容，这些提示应作为库的一部分添加或添加到 GraalVM 可访问性元数据存储库。为此，您可能需要在项目的问题跟踪器（Eclipse 序列化程序）中创建一个问题，并要求他们将其添加到其 JAR 或可达性元数据存储库中。如果您包含通过运行代理获得的
