示例1: testInjectionTarget

import javax.enterprise.inject.spi.BeanManager; //导入方法依赖的package包/类
@Test
public void testInjectionTarget() {
	BeanManager beanManager = current().getBeanManager();
	// CDI uses an AnnotatedType object to read the annotations of a class
	AnnotatedType<String> type = beanManager.createAnnotatedType(String.class);
	// The extension uses an InjectionTarget to delegate instantiation,
	// dependency injection
	// and lifecycle callbacks to the CDI container
	InjectionTarget<String> it = beanManager.createInjectionTarget(type);
	// each instance needs its own CDI CreationalContext
	CreationalContext<String> ctx = beanManager.createCreationalContext(null);
	// instantiate the framework component and inject its dependencies
	String instance = it.produce(ctx); // call the constructor
	it.inject(instance, ctx); // call initializer methods and perform field
								// injection
	it.postConstruct(instance); // call the @PostConstruct method
	// destroy the framework component instance and clean up dependent
	// objects
	assertNotNull("the String instance is injected now", instance);
	assertTrue("the String instance is injected now but it's empty", instance.isEmpty());
	it.preDestroy(instance); // call the @PreDestroy method
	it.dispose(instance); // it is now safe to discard the instance
	ctx.release(); // clean up dependent objects
