spring bean加载模式

1.mbd.isSingleton()单例
2.mbd.isPrototype()原型，即多例
3.ohter，Request、Session等

我们可以通过打断点查看你的bean是如何加载的：

beanName.indexOf("factoryBeanService") > 0 ? true : false

类:org.springframework.beans.factory.support.AbstractBeanFactory;

// 单例模式创建
if (mbd.isSingleton()) {
    sharedInstance = getSingleton(beanName, () -> {
        try {
            return createBean(beanName, mbd, args);
        }
        catch (BeansException ex) {
            //从单例缓存中显式删除实例：它可能已经放在那里迫切需要创建过程，以允许循环引用解析。还要删除所有收到对该bean的临时引用的bean。
            destroySingleton(beanName);
            throw ex;
        }
    });
    bean = getObjectForBeanInstance(sharedInstance, name, beanName, mbd);
}
//原型模式创建
else if (mbd.isPrototype()) {
    //这是一个原型->创建一个新实例。
    Object prototypeInstance = null;
    try {
        beforePrototypeCreation(beanName);
        prototypeInstance = createBean(beanName, mbd, args);
    }
    finally {
        afterPrototypeCreation(beanName);
    }
    bean = getObjectForBeanInstance(prototypeInstance, name, beanName, mbd);
}
//其他Request等
else {
    String scopeName = mbd.getScope();
    final Scope scope = this.scopes.get(scopeName);
    if (scope == null) {
        throw new IllegalStateException("No Scope registered for scope name '" + scopeName + "'");
    }
    try {
        Object scopedInstance = scope.get(beanName, () -> {
            beforePrototypeCreation(beanName);
            try {
                return createBean(beanName, mbd, args);
            }
            finally {
                afterPrototypeCreation(beanName);
            }
        });
        bean = getObjectForBeanInstance(scopedInstance, name, beanName, mbd);
    }
    catch (IllegalStateException ex) {
        throw new BeanCreationException(beanName,
                "Scope '" + scopeName + "' is not active for the current thread; consider " +
                        "defining a scoped proxy for this bean if you intend to refer to it from a singleton",
                ex);
    }
}
