BeanFactory

  • BeanFactory 是 Spring IoC 的一种容器
  • Spring IoC 容器是一个管理 Bean 的工厂，在 Spring 的定义中，它要求所有的 IoC 容器都需要实现接口 BeanFactory
  • BeanFactory 是所有 IoC 容器的顶级接口

/**
 * The root interface for accessing a Spring bean container.
 * This is the basic client view of a bean container;
 * further interfaces such as {@link ListableBeanFactory} and
 * {@link org.springframework.beans.factory.config.ConfigurableBeanFactory}
 * are available for specific purposes.
 *
 * <p>This interface is implemented by objects that hold a number of bean definitions,
 * each uniquely identified by a String name. Depending on the bean definition,
 * the factory will return either an independent instance of a contained object
 * (the Prototype design pattern), or a single shared instance (a superior
 * alternative to the Singleton design pattern, in which the instance is a
 * singleton in the scope of the factory). Which type of instance will be returned
 * depends on the bean factory configuration: the API is the same. Since Spring
 * 2.0, further scopes are available depending on the concrete application
 * context (e.g. "request" and "session" scopes in a web environment).
 *
 * <p>The point of this approach is that the BeanFactory is a central registry
 * of application components, and centralizes configuration of application
 * components (no more do individual objects need to read properties files,
 * for example). See chapters 4 and 11 of "Expert One-on-One J2EE Design and
 * Development" for a discussion of the benefits of this approach.
 *
 * <p>Note that it is generally better to rely on Dependency Injection
 * ("push" configuration) to configure application objects through setters
 * or constructors, rather than use any form of "pull" configuration like a
 * BeanFactory lookup. Spring's Dependency Injection functionality is
 * implemented using this BeanFactory interface and its subinterfaces.
 *
 * <p>Normally a BeanFactory will load bean definitions stored in a configuration
 * source (such as an XML document), and use the {@code org.springframework.beans}
 * package to configure the beans. However, an implementation could simply return
 * Java objects it creates as necessary directly in Java code. There are no
 * constraints on how the definitions could be stored: LDAP, RDBMS, XML,
 * properties file, etc. Implementations are encouraged to support references
 * amongst beans (Dependency Injection).
 *
 * <p>In contrast to the methods in {@link ListableBeanFactory}, all of the
 * operations in this interface will also check parent factories if this is a
 * {@link HierarchicalBeanFactory}. If a bean is not found in this factory instance,
 * the immediate parent factory will be asked. Beans in this factory instance
 * are supposed to override beans of the same name in any parent factory.
 *
 * <p>Bean factory implementations should support the standard bean lifecycle interfaces
 * as far as possible. The full set of initialization methods and their standard order is:
 * <ol>
 * <li>BeanNameAware's {@code setBeanName}
 * <li>BeanClassLoaderAware's {@code setBeanClassLoader}
 * <li>BeanFactoryAware's {@code setBeanFactory}
 * <li>EnvironmentAware's {@code setEnvironment}
 * <li>EmbeddedValueResolverAware's {@code setEmbeddedValueResolver}
 * <li>ResourceLoaderAware's {@code setResourceLoader}
 * (only applicable when running in an application context)
 * <li>ApplicationEventPublisherAware's {@code setApplicationEventPublisher}
 * (only applicable when running in an application context)
 * <li>MessageSourceAware's {@code setMessageSource}
 * (only applicable when running in an application context)
 * <li>ApplicationContextAware's {@code setApplicationContext}
 * (only applicable when running in an application context)
 * <li>ServletContextAware's {@code setServletContext}
 * (only applicable when running in a web application context)
 * <li>{@code postProcessBeforeInitialization} methods of BeanPostProcessors
 * <li>InitializingBean's {@code afterPropertiesSet}
 * <li>a custom init-method definition
 * <li>{@code postProcessAfterInitialization} methods of BeanPostProcessors
 * </ol>
 *
 * <p>On shutdown of a bean factory, the following lifecycle methods apply:
 * <ol>
 * <li>{@code postProcessBeforeDestruction} methods of DestructionAwareBeanPostProcessors
 * <li>DisposableBean's {@code destroy}
 * <li>a custom destroy-method definition
 * </ol>

BeanFactory 解读

重要方法：

// 获取一个 Bean 对象方法（name 为需要判断的 Bean 名称，以下同上）
Object getBean(String name) throws BeansException;

// 是否包含某个 Bean 对象方法
boolean containsBean(String name);

// 判断 Bean 对象是否是单例（默认情况下，在 Spring BeanFactory 中创建的 Bean 是单例，但可以在创建时指定创建的 Bean 的建造类型）
boolean isSingleton(String name) throws NoSuchBeanDefinitionException;

// 判断 Bean 对象是否是原型
boolean isPrototype(String name) throws NoSuchBeanDefinitionException;

// 获取 Bean 对象的类型
Class<?> getType(String name) throws NoSuchBeanDefinitionException;

// 获取 Bean 对象的别名
String[] getAliases(String name);

  • 首先我们看到了多个 getBean 方法，这也是 IoC 容器最重要的方法之一，它的意义是从 IoC 容器中获取 Bean 。而从多个getBean 方法中可以看到有按类型（by type）获取 Bean 的，也有按名称（by name）获取 Bean 的，这就意味着在 Spring IoC 容器中，允许我们按类型或者名称获取 Bean ，这对理解 Spring 的依赖注入（Dependency Injection，DI）是十分重要的。

  • isSingleton 方法则判断 Bean 是否在 Spring IoC 中为单例。这里需要记住的是在 Spring IoC 容器中，默认的情况下，Bean 都是以单例存在的，也就是使用 getBean 方法返回的都是同一个对象。与 isSingleton 方法相反的是 isPrototype 方法，如果它返回的是 true，那么当我们使用 getBean 方法获取 Bean 的时候，Spring IoC 容器就会创建一个新的 Bean 返回给调用者，这些与后面将讨论的 Bean 的作用域相关。

ApplicationContext

  • 由于 BeanFactory 的功能还不够强大，因此 Spring 在 BeanFactory 的基础上，还设计了一个更为高级的接口 ApplicationContext 。它是 BeanFactory 的子接口之一，在 Spring 的体系中 BeanFactory 和 ApplicationContext 是最为重要的接口设计，在现实中我们使用的大部分 Spring IoC 容器是 ApplicationContext 接口的实现类

  • ApplicationContext 接口通过继承上级接口，进而继承 BeanFactory 接口，但是在 BeanFactory 的基础上，扩展了消息国际化接口（MessageSource）、环境可配置接口（EnvironmentCapable）、应用事件发布接口（ApplicationEventPublisher）和资源模式解析接口（ResourcePatternResolver），所以它的功能会更为强大。
