How to #Autowire generic type to inner generic class' bean without xml configuration? - spring

Question

I have a generic class DefaultBatchReportService.
I want to pass different POJO class, Service & Dao into this generic class.
However, I find difficulties in passing specific classes to generic abstract class with inner autowired generic class.
I got errors as following:

Batch Report Service:
#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 Class:
#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
}
}
In this project, my team is using JSF-Spring integrated framework. Normal standard injection of controls works fine (without Generic Types).
There are more than one Batch Report with same procedures in my project, thats why I want to use DefaultBatchReportService to handle every BatchReport by passing different class to it. (RT001..., RT002..., RT003..) Then, developers can focus on drawing the 'single' report.
Sorry for my poor English :/
