How to use Plexus :: default Container in the Java library for component management

How to use Plexus :: default Container in the Java library for component management Plexus :: Default Container is a Java class library for component management and dependence.It allows developers to create and manage various components in applications and provide convenient dependency injection functions.The following is the steps of using Plexus :: Default Container for component management: Step 1: Add dependencies First, you need to add the Plexus :: default Container library to the dependency item of the project.In the Maven project, the following dependencies can be added to the POM.XML file: <dependency> <groupId>org.codehaus.plexus</groupId> <artifactId>plexus-container-default</artifactId> <version>1.7.0</version> </dependency> Step 2: Create components Next, you need to create some components, which will be managed by Plexus :: Default Container.A component can be an ordinary Java class that needs to add some specific annotations. @Component(role = MyComponent.class) public class MyComponent { // The attributes and methods of the component } In the above example,@Component annotation marks this class as a component and specify its role. Step 3: Initialization container Before using the component, you need to initialize the Plexus :: default Container.You can initialize in the following way: DefaultContainerConfiguration configuration = new DefaultContainerConfiguration(); configuration.setName("my-container"); Container container = new DefaultContainer(configuration); container.addComponent(MyComponent.class, DefaultMyComponent.class); container.initialize(); In the above example, first create a defaultContainerConfiguration object and set its name.Then create a DefaultContainer object and add a DEFAULTMYCOMPONENT class that implements the Mycomponent interface to the container.Finally, call the initialize () method initialization container. Step 4: Use components Once the container is initialized, you can use Plexus :: Default Container to obtain and use components.The example of the component can be obtained in the following ways: MyComponent myComponent = container.getComponent(MyComponent.class); In the above example, by calling the getComponent () method and specifying the type of the component, the instance of the component can be obtained. Step 5: Destroy the container After the use of Plexus :: default Container, the container should be destroyed.Can be destroyed in the following ways: container.dispose(); The above is the basic steps for component management using Plexus :: default Container.Through this library, you can easily create and manage various components and realize the relying in injection function.
