1、BeanFactory接口

package org.springframework.beans.factory;

import org.springframework.beans.BeansException;
import org.springframework.core.ResolvableType;

public interface BeanFactory {
    String FACTORY_BEAN_PREFIX = "&";
    // getBean()方法从容器中返回Bean
    Object getBean(String var1) throws BeansException;

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

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

    <T> T getBean(Class<T> var1) throws BeansException;

    <T> T getBean(Class<T> var1, Object... var2) throws BeansException;
    // 容器里有没有一个Bean
    boolean containsBean(String var1);
    // 一个Bean是不是单例的
    boolean isSingleton(String var1) throws NoSuchBeanDefinitionException;
    // 一个Bean是不是复例的
    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);
}
