我有一个泛型类DefaultBatchReportService . 我想将不同的POJO类，Service＆Dao传递给这个泛型类 .

但是，我发现使用内部自动装配泛型类将特定类传递给泛型抽象类时遇到了困难 .

我得到的错误如下：

@Component
@Scope("prototype")
public class DefaultBatchReportService <T extends SingleReportService, I extends ReportInputParam, M extends ReportMeta, MD extends ReportMetaDetail, C extends ReportContent, P extends ReportDao<I , M, MD, C>> {
    @Setter
    private I inputParam;
    @Setter
    private M meta;

    @Autowired
    @Setter
    private T singleReportService;
    @Autowired
    @Setter
    private P reportDao; 
}

Managed Bean类：

@Component
@SpringScopeView
@Getter
@Setter
public class RT001Bean extends BaseBean {
    @Autowired
    private DefaultBatchReportService<RT001Service, RT001_InputParam, RT001_Meta, RT001_Meta.Detail, RT001_Content, RT001Dao> bReportController;

    private RT001_InputParam inputParam;

    public void generateBatchReport() {

        //Start Report Generation
        try {
            bReportController.doSomething(inputParam);
            ....
        } catch (CustomException e) {
            // Print Error Message

    }
}

在这个项目中，我的团队正在使用JSF-Spring集成框架 . 正常标准的控件注入工作正常（没有通用类型） .

在我的项目中有多个具有相同过程的批处理报告，这就是为什么我想通过将不同的类传递给它来使用DefaultBatchReportService来处理每个BatchReport . （RT001 ...，RT002 ...，RT003 ..）然后，开发人员可以专注于绘制“单一”报告 .

抱歉我的英语不好：/

如何@Autowire泛型类型到内部泛型类'bean没有xml配置？
