Hello Ranchers,

I am facing some a problem for injecting my service instance of controller using IoC... I want to import the csv file and parse it according to the type. here type provides me which parse method i can use for parsing the csv file. Following is the classes i am using:

And i have the specific implementation of this ParseService according to the CSV file i.e if i am importing the Student record then i have StudentParseServiceImpl likewise if i am importing the Employee then i have EmployeeParseServiceImpl class.

now in my ImportController i have

parseService instance which i want to inject using the specific implementation of PraseService as mentioned earlier.

So, the question is How can i inject parseService at run-time using the type of file i am importing ?

Thanks

Rahul
