本文整理了Java中org.springframework.beans.factory.BeanFactory.getBean()方法的一些代码示例，展示了BeanFactory.getBean()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。BeanFactory.getBean()方法的具体详情如下：
包路径：org.springframework.beans.factory.BeanFactory
类名称：BeanFactory
方法名：getBean

BeanFactory.getBean介绍

[英]Return the bean instance that uniquely matches the given object type, if any.

This method goes into ListableBeanFactory by-type lookup territory but may also be translated into a conventional by-name lookup based on the name of the given type. For more extensive retrieval operations across sets of beans, use ListableBeanFactory and/or BeanFactoryUtils.
[中]返回唯一匹配给定对象类型的bean实例（如果有）。
此方法进入ListableBeanFactory的按类型查找区域，但也可以根据给定类型的名称转换为传统的按名称查找。要跨多组bean执行更广泛的检索操作，请使用ListableBeanFactory和/或BeanFactoryUtils。
