一句话介绍

BeanFactory接口用来生产Bean，它处理生产bean的接口体系的最顶层，getBean方法可以获取bean。FactoryBean接口用来定制Bean的生产过程，getObject方法中可以实现自定义过程。

源码

BeanFactory源码 

public interface BeanFactory {
    String FACTORY_BEAN_PREFIX = "&";

    Object getBean(String var1) throws BeansException;

     T getBean(String var1, Class var2) throws BeansException;

     T getBean(Class var1) throws BeansException;

    Object getBean(String var1, Object... var2) throws BeansException;

     T getBean(Class var1, Object... var2) throws BeansException;

    boolean containsBean(String var1);

    boolean isSingleton(String var1) throws NoSuchBeanDefinitionException;

    boolean isPrototype(String var1) throws NoSuchBeanDefinitionException;

    boolean isTypeMatch(String var1, ResolvableType var2) throws NoSuchBeanDefinitionException;

    boolean isTypeMatch(String var1, Class var2) throws NoSuchBeanDefinitionException;

    Class getType(String var1) throws NoSuchBeanDefinitionException;

    String[] getAliases(String var1);
}

FactoryBean源码

public interface FactoryBean {
    T getObject() throws Exception;

    Class getObjectType();

    boolean isSingleton();
}

public interface FactoryBean {
    T getObject() throws Exception;

    Class getObjectType();

    boolean isSingleton();
}
