聊透spring @Configuration配置类
m0_71777195的博客

本章节我们来探索Spring中一个常用的注解。。那啥是配置类啊，有啥用啊。这个我们得结合实际使用场景来说，通常情况下。加了的配置类内部，都会。为了简化定义，在后续我们称@Bean注解的方法为工厂方法。配置类的奥秘就在这里，Spring会保证多次调用@Bean标注的工厂方法，，这也贯彻了Spring的单例哲学。多次调用创建方法，产生的竟然是同一个对象，这貌似违背了编程的基础原理。怎么可能😱，一定是Spring做了什么，那就跟随着贰师兄的脚步一起解开的神秘面纱吧。

概述 Spring中存在这样一个工具类ConfigurationClassEnhancer,它会对应用中每个配置类，也就是一般通过@Configuration注解定义的类进行一个增强。通过增强以后，配置类中使用@Bean注解的bean定义方法就不再是普通的方法了，它们具有了如下跟bean作用域有关的能力，以单例bean为例 ： 1. 它们首次被调用时，相应方法逻辑会被执行用于创建bean实例； 2...

刨析Spring的@Configuration注解属性proxyBeanMethods原理
flyfhj的博客
02-02 3726
Spring框架中有一个出现频次很高的注解@Configuration，特别是在SpringBoot的spring-boot-autoconfigure包中，可以发现每个配置类基本都会加上@Configuration(proxyBeanMethods=false)注解(注：Spring 5.2+)，其中proxyBeanMethods属性起到什么作用呢？今天我们就通过源码探究它的底层原理。

无论是哪家公司，都很重视高并发高可用的技术，重视基础，重视JVM。面试是一个双向选择的过程，不要抱着畏惧的心态去面试，不利于自己的发挥。同时看中的应该不止薪资，还要看你是不是真的喜欢这家公司，是不是能真的得到锻炼。其实我写了这么多，只是我自己的总结，并不一定适用于所有人，相信经过一些面试，大家都会有这些感触。最后我整理了一些面试真题资料，技术知识点剖析教程，还有和广大同仁一起交流学习共同进步，还有一些职业经验的分享。

【Spring注解必知必会】深度解析@Configuration注解
m0_71777195的博客

最近在看源码的时候，发现很多源码中写着，引起了我的好奇，为啥这么写， 这个proxyBeanMethods属性是干嘛的？和@Component注解有什么区别呢？注解可以加在类上，让这个类的功能等同于一个bean xml配置文件，可以在这个类中管理创建Bean。@Component}复制代码value: 自定义当前组件或者说bean的名称，实际就是@Component的value属性。proxyBeanMethods： 判断是否bean的方法应该被代理，默认是true，后面原理解析中重点分析。
