通过上述表格的对应关系，springboot2.6.6版本默认依赖的spring framework版本为5.3.18，所以可以通过升级springboot版本来升级spring framework的版本。
如果项目的parent中使用的是
spring-boot-starter-parent
，那么可以直接修改该版本号为2.6.6
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.6.6</version> <relativePath/> <!-- lookup parent from repository --> </parent>
如果parent中使用的是其他父依赖，那么可以通过在pom文件中添加spring-boot.version解决
<properties> <spring-boot.version>2.6.6</spring-boot.version> </properties>

pagehelper循环依赖：
com.github.pagehelper.autoconfigure.PageHelperAutoConfiguration
解决方式：由于springboot2.6禁止循环依赖导致，升级到1.4.1解决
对于maven项目，我通过dependencyManagement标签直接升级了spring framework：
<dependencyManagement> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>5.3.18</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>5.3.18</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>5.3.18</version> </dependency> </dependencyManagement>

springboot项目可通过升级springboot版本来升级默认依赖的spring framework版本
-
maven项目可直接在标签中直接指定spring framework相关依赖的版本
Spring
Framework
存在身份认证绕过漏洞，当
Spring
Security使用mvcRequestMatcher配置并将“**“作为匹配模式时，在
Spring
Security 和
Spring
MVC 间会发生模式不匹配，最终可能导致身 份认证绕过。解决办法：将
Spring
Framework
升级到5.3.26、6.0.7 及以上版。
目前（截至我知识更新的时间点），
Spring
Framework
的最新稳定
版本
是 5.x 系列，而且社区正在积极地开发下一个主
版本
，即
Spring
6，预计会带来更多的创新和改进，包括对新特性的支持，如 Jakarta EE 9+ 的兼容性，以及可能的性能提升和 API 改进。6. **
Spring
Boot
**：虽然不是一个单独的
版本
，但它是与
Spring
框架紧密相关的项目，提供了快速启动和运行
Spring
应用程序的能力，简化了项目的初始设置过程。
方法一，往往很多程序员不敢贸然升级
spring
boot
版本
，怕造成其他影响，那么可以直接升级
spring
版本
。直接升级
spring
boot
的
版本
，然后查看依赖树，会发现
spring
版本
也会跟着升级。可以发现
spring
boot
其实也是引用的
版本
，那么直接在项目顶层的。
（1）为所有
Spring
开发提供一个更快更广泛的入门体验。
（2）零配置。无冗余代码生成和XML 强制配置，遵循“约定大于配置” 。
（3）集成了大量常用的第三方库的配置，
Spring
Boot
应用为这些第三方库提供了几乎可以零配置的开箱即用的能力。
（4）提供一系列大型项目常用的非功能性特征，如嵌入服务器等。

小编也是很有感触，如果一直都是在中小公司，没有接触过大型的互联网架构设计的话，只靠自己看书去提升可能一辈子都很难达到高级架构师的技术和认知高度。向厉害的人去学习是最有效减少时间摸索、精力浪费的方式。我们选择的这个行业就一直要持续的学习，又很吃青春饭。虽然大家可能经常见到说程序员年薪几十万，但这样的人毕竟不是大部份，要么是有名校光环，要么是在阿里华为这样的大企业。年龄一大，更有可能被裁。送给每一位想学习
Java
小伙伴，用来提升自己。
