Issue with dependency injection in custom plugins in Jira 10

[Ravi Saurav]

Hi I am currently working on a custom plugin after upgrading from Jira 9 to Jira 10.3.2.

There are lot of changes which is exactly breaking the plugin flow.
I cannot do @ComponentImport on lots of objects(TemplateRenderer, ActiveObjects etc) from the osgi bundle into a classes such as 

@Component
public class CustomPluginServlet extends HttpServlet {

            

@Inject
public CustomPluginServlet(@ComponentImport UserManager userManager) {
  this.userManager = ComponentAccessor.getUserManager();
}

or in classes such as

@Path("/samplePath")
@Component
public class CustomConfigRestResource {


private final TransactionTemplate transactionTemplate;

@Inject
public CustomConfigRestResource(@ComponentImport TransactionTemplate transactionTemplate) {

this.transactionTemplate = transactionTemplate;



}

Is there a way to overcome this? Secondly I have a custom class in my plugin very similar to shown below.

Named
@ExportAsService({TransactionTemplate.class})
public class MyTransactionTemplate implements TransactionTemplate {

    private ActiveObjects ao;

    @Inject
    public MyTransactionTemplate(@ComponentImport ActiveObjects ao) {
        this.ao = ao;
    }

    @Override
    public <T> T execute(TransactionCallback<T> action) {
        return ao.executeInTransaction(() -> {
            try {
                return action.doInTransaction();
            } catch (Exception e) {
                throw new RuntimeException(e);
            }
        });
    }
}

How do I inject this in the class CustomPluginServlet shown above?
