Annotation Type ConstructorArg
-
@Retention(RUNTIME) @Target(PARAMETER) public @interface ConstructorArg
Annotation for the auto injection of immutable beans. As with Java up to version 8 is not possible to retrieve the constructor's parameter name through reflection, this annotation needs to be specified next to each one of them. e.g.public class Square { private final int x; private final int y; public Square(@ConstructorArg("x") final int x, @ConstructorArg("y") final int y) { this.x = x; this.y = y; } }
