本文解决了一个关于org.springframework.beans.factory.BeanCreationException的问题，错误出现在尝试创建名为‘car’的bean时，由于postProcessBeforeInitialization方法未返回bean导致初始化失败并抛出空指针异常。

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘car’ defined in class path resource [beans-cycle.xml]: Invocation of init method failed; nested exception is java.lang.NullPointerException

在添加bean后置处理器后报错无法调用初始化方法，原因是空指针，后发现postProcessBeforeInitialization忘了返回bean
解决方法：在初始化之前那个postProcessBeforeInitialization方法返回bean

Spring源码——bean的加载

前言 内容主要参考自《Spring源码深度解析》一书，算是读书笔记或是原书的补充。进入正文后可能会引来各种不适，毕竟阅读源码是件极其痛苦的事情。 本文主要涉及书中第五章的部分，依照书中内容以及个人理解对Spring进行了注释，详见Github仓库：https://github.com/MrSorrow/spring-framework 在前几篇文章中，我们已经完成了将XML配置文件的信息转换为 B...
spring bean的继承和依赖

既然spring提供了继承，那么也就存在了专门用于被继承的bean，而不进行实例化，这种bean被称为抽象bean，使用abstract="true"表明这是一个抽象bean。有时候需要保证bean实例化的先后顺序，在创建一个bean的时候必须保证另外一个bean也被创建，如果另一个bean不存在，则无法正常实例化该bean。spring除了提供了一般的配置bean的方式之外，还实现了java中继承的特性，设置bean的父子关系，这样对于一些重复的配置就可以进行省略。bean的继承和依赖。

文章目录一、问题描述二、解决思路1.保持SpringBoot启动类的@MapperScan2.在*.mapper接口上加上@mapper 一、问题描述 最近在使用MybatisPlus时遇到了一个小问题，这是项目结构： 刚开始在SpringBootApplication中添加了扫描的mapper类位置： @SpringBootApplication @MapperScan("com.example.mybatisplusdemo.mapper") public class MybatisPlusDemo

摘要：使用若依框架时，修改代码后重启项目偶尔出现BeanCreationException错误，原因是equity-admin模块中使用了equity-system模块的功能但未添加依赖。添加依赖后问题解决。AI解释未添加依赖时有时不报错的可能原因是：1)项目可能缓存了部分类信息；2)某些情况下类加载顺序影响；3)热部署机制导致部分类被保留。建议通过添加依赖彻底解决该问题。(150字)
Spring 报错：Error creating bean with name的解决方法

就是Mapper类没有添加@Mapper注解

出现：Error creating bean with name 'XXX' defined in class path resource [applicationContext.xml]: BeanPostProcessor before instantiation of bean failed。AspectJ与Spring框架毫无依赖关系，作为一个完全独立的AOP框架使用。SpringAOP时AOP的一种实现方案，3.0版本后以来AspectJ的部分功能，在使用时需要导入AspectJ依赖。

项目场景： 在SpringBoot项目启动时的报错，切身体验，记录解决报错全过程，希望能给看到的人一些解决方案和思路。在遇到诸如此类的项目启动报错时，不要无从下手，仔细去从报错日志中寻找有效的信息。要坚定信念：事出有妖必有因。 问题描述： 既然是问题，那就直接贴上报错日志：Error creating bean with name 'mapperScannerConfigurer' defined in class path resource [com/gwm/tsp/boot/dao/confi..

实际上在创建新项目的时候，idea会自动加载maven项目包，如果自己之前对maven有过修改或者增删，那么可能会导致，maven数据丢失，但是实际上，idea默认的maven本地仓库是不变的。创建项目的本地仓库会一直是这个，那么如果maven缺失，仓库信息不完整，就有可能出现初始化加载问题，那么我们把仓库改个位置，重新加载maven数据，就好了。
BeanCreationException: Error creating bean with name ‘xxx‘ defined in class path resource ...解决方案

这个报错是因为循环依赖问题，当husband-bean的属性中有wife-bean，而wife-bean的属性中有husband-bean，恰巧在Spring配置文件中 scope的值设置成"prototype"，会创建多个bean,这样创建husband-bean时,在给wife属性赋值时，又会去找wife-bean，给husband属性赋值时，又去创建husband-bean......这样就会陷入循环。
