Using Components
$3
All JEC JDI components have to be imported with the ES6 syntax:
`javascript
import { Inject } from "jec-jdi";
import { GreetingService } from "./sevices/GreetingService";
export class HelloWorld {
@Inject({
type: GreetingService,
qualifier: "en_EN"
})
private _service:GreetingService;
public sayHelloWorld():string {
return this._service.sayHello();
}
}
`
Because of TypeScript restrictions, you must use the Interface construct to directly use interfaces as type reference for an injection point:
`javascript
import {Interface} from "jec-commons";
export interface GreetingService {
sayHelloWorld():string;
}
export const GreetingService = Interface("services.GreetingService");
`
$3
JDI provides the ability to use shorten declarations, instead of initializers, to perform dependency injection. You can use either the type, or the name reference of the bean, to specify dependency injection:
`javascript
import { Inject } from "jec-jdi";
import { MyService } from "./sevices/MyService";
import { MyOtherService } from "./sevices/MyOtherService";
export class HelloWorld {
@Inject(MyService)
private _service:MyService;
@Inject("MyBeanName")
private _otherService:MyOtherService;
}
`
