缺少依賴關係

Question

簡單基本獲取api並獲取字符串數據工作正常。後來我增強了該類的自動裝載依賴項，我收到一個錯誤。

我springbean.xml

<context:exclude-filter expression="org.springframework.stereotype.Controller" 
     type="annotation" /> 

    <context:exclude-filter 
     expression="org.springframework.context.annotation.Configuration" 
     type="annotation" /> 
</context:component-scan> 

public interface ToApiJsonSerializer<T> { 
} 

@Component 
    public class DefaultSerialization<T> implements ToApiJsonSerializer<T>{ 

    private final GoogleGsonSerializerHelper helper; 

    @Autowired 
    public DefaultToApiJsonSerializer(
     final GoogleGsonSerializerHelper helper) { 
     this.helper = helper; 
    } 
    } 
@Service 
public final class GoogleGsonSerializerHelper { 

    }

長期試驗後問題得到了解決。 在根包初始配置類中，我添加了@componentScan這個問題。服務器已啓動並正在運行。
