Bring

What is Bring?

Bring is a dependency injection framework. It uses IoC (Inversion of Control) container, which is represented by ApplicationContext where beans are managed. The framework can create beans for you and inject them as dependencies to other beans

Quick Start

To install Bring locally you should:

• clone repo https://github.com/overpathz/bring-hoverla
• go to the root of Bring project cd <path_to_bring>/Bring
• build jar with mvn clean install -DskipTests
• add jar to your maven project

<dependency>
    <groupId>com.bobocode.hoverla</groupId>
    <artifactId>bring</artifactId>
    <version>1.0-SNAPSHOT</version> 
</dependency>

To easily start an application with Bring, use the BringApplication.loadContext("package.to.scan") method

import com.bobocode.hoverla.bring.BringApplication;
import com.bobocode.hoverla.bring.context.ApplicationContext;

public class DemoApp {
    public static void main(String[] args) {
        ApplicationContext applicationContext = BringApplication.loadContext("packages.to.scan"); // provide packages to be scanned for beans 
    }
}

If you need to customize loading of ApplicationContext, you can do it with ApplicationContextBuilder. Here's an example of its usage:

import ch.qos.logback.classic.Level;
import com.bobocode.hoverla.bring.BringApplication;
import com.bobocode.hoverla.bring.context.ApplicationContext;

public class DemoApp {
    public static void main(String[] args) {
        ApplicationContext applicationContext = BringApplication.getContextBuilder()
                .logLevel(Level.DEBUG)                  // provide logging level
                .packagesToScan("packages.to.scan")     // provide packages to be scanned for beans
                .build();
    }
}

Creation components of ApplicationContext:

• BeanDefinitionMapper. Using to create BeanDefinition.
• BeanAnnotationScanner. Using for scan packages to find classes annotated with Bean and create it at ApplicationContext.
• BeanDependencyNameResolver. Its util class using to resolve BeanDependency names.
• BeanInitializer. Using for initialize beans.

Main API (annotations):

• Autowired
• Bean
• Configuration
• Primary
• Value
