> -----------------------------------------------------------------------------------------------------
>
> Key: TAP5-529
> URL: https://issues.apache.org/jira/browse/TAP5-529
> Project: Tapestry 5
> Issue Type: Improvement
> Components: tapestry-core
> Affects Versions: 5.1.0.0, 5.0.18
> Reporter: Yunhua Sang
> Priority: Minor
>
> Sometimes a component doesn't know which instance of a common interface is
> going to be used at design time; the appropriate instance of a common
> interface will be injected at runtime. For example, a JDBCTable component is
> using a DataSource:
> public class JDBCTable {
> @Inject
> private DataSource dataSource;
> @Parameter(required = true, defaultPrefix = "literal")
> private String table;
> ....
> }
> When there are multiple DataSource existing, it seems hard to inject a
> DataSource I wanted into this component, a possible way is to make dataSource
> a parameter.
> It would be nice that Tapestry 5 can remove this kind of ambiguities of
> injection by attaching an annotation marker(s) with @Component, as
> @Oracle
> @Component
> private JDBCTable jdbcTable;
> The @Oracle should has higher priority than the one(s) already defined in the
> component.
