Overview

Bring framework is a small project which is self-written dependency injection container with learning purpose.

Building

In order to add our DI container to your project, you need to do these steps:

First, add a jitpack.io resource to your pom.xml file:

<repositories>
    <repository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </repository>
</repositories>

Second, add dependency of our project:

<dependency>
    <groupId>com.github.b-bodnar</groupId>
    <artifactId>bring-framevork</artifactId>
    <version>e3789616df735b52992dcc236b23cad9a744da28</version>
</dependency>

Third, add these lines in your main class to get application context:

    ApplicationContext context = Application.run(nameOfYourPackageToScan);

And that pretty much it. It will scan your package to find all the interfaces and implementation classes, that are marked with @Component annotation. If you want to inject services please use field injection with @Autowired annotation. Constructor injection is not yet supported. For example, this is format of injecting FirstService inside SComponent class:

public class SComponent {

 @Autowired
 private FirstService firstService;

If your interface or service has multiple implementations, after @Autowired annotation do not forget to add @Qualifier annotation with name of the implementation as a value:

@Autowired
@Qualifier("SecondServiceImpl")
private SecondService secondService;

Also do not forget to add an application.properties file to your project to avoid exception related to it. If you want to get some parameters from application.properties files firstly you need to add them there and secondly add @Value annotation with a name of needed property above the field. Or you can leave the value blank if the name of the property is the same as the name of the field. Example:

@Value("")
private String alcohol;
