我在我的 spigot 插件中使用 Guice 的辅助注入时遇到问题，并且似乎无法缩小问题范围。这是我得到的错误：

    ... 39 more

这是我的活页夹类：

public class MainBinder extends AbstractModule {

@Override
protected void configure() {
    bind(DestinyMC.class).toInstance(this.plugin);

    install(new FactoryModuleBuilder().build(InventoryFromFileFactory.class));
}

当我注释掉安装行时，错误消失了。那条线使用这个工厂类

public interface InventoryFromFileFactory {
    InventoryFromFile create(String targetRootKey, String targetFile);
}

其中声明了在创建此类对象时需要手动提供的参数：

public class InventoryFromFile {
    @Inject
    public InventoryFromFile
    (
        @Assisted String targetRootKey,
        @Assisted String targetFile,
        ConfigAccessorFactory configAccessorFactory
    )
    {
        ConfigurationSection targetCS = configAccessorFactory.create(targetFile).getCustomConfig().getConfigurationSection(targetRootKey);
    ...
    }
}

这ConfigAccessFactory是另一个辅助注入的工厂类

public interface ConfigAccessorFactory {
    ConfigAccessor create(String filename);
}

在这里使用：

public class ConfigAccessor {
    private Plugin plugin;
    private final String customFileName;

    @Inject
    public ConfigAccessor
    (
        @Assisted String fileName,
        DestinyMC plugin
    )
    {
        this.customFileName = fileName;
        this.plugin = plugin;
    }
    ...
}

最后，DestinyMC依赖是 spigot 插件的主类：

public class DestinyMC extends JavaPlugin {
//Inject dependencies
@Inject private ConfigAccessorFactory configAccessorFactory;

//Code only run once when the plugin is enabled
public void onEnable() {
    MainBinder mainBinder = new MainBinder(this);
    Injector injector = Guice.createInjector(mainBinder);
    injector.injectMembers(this);

    //Saves config files to disk if they don't exist
    saveDefaultConfig();
    Arrays.asList(
        "inventory-gui.yml",
        "player-tree-template.yml",
        "player-tree-data.yml"
    ).forEach((file) -> {
        configAccessorFactory.create(file).saveDefaultConfig();
    });
    ...
}

我不太确定我做错了什么，但我对 Guice 还很陌生，所以我很可能误解了一些东西。另外，如果有更好的方法可以做到这一点，请告诉我。谢谢您的帮助。
