fasterxml jackson databind 升级至 2.15.2

Question

我正在尝试将 fastxml jackson databind 从版本 2.9.3 升级到 2.15.2。

但是我收到以下运行时错误，构建成功。

Springboot 版本 - 2.2.6

我用作参考的文章：https://dzone.com/articles/jackson-dependency-issue-in-spring-boot-with-maven

有人能告诉我到底为什么会发生这种情况以及解决方案吗？

Spring Boot 管理 Jackson 依赖项，并且在某些情况下依赖于它们（这就是您收到该错误的原因）

您可以在此处检查哪个启动带来哪个版本，例如 2.7.X、3.0.X 和 3.1.X（pivotal 仍然支持的所有版本）

https://docs.spring.io/spring-boot/docs/2.7.16/reference/html/dependency-versions.html

https://docs.spring.io/spring-boot/docs/3.0.4/reference/html/dependency-versions.html

https://docs.spring.io/spring-boot/docs/3.1.4/reference/html/dependency-versions.html

在那里你可以看到3.1.X默认带来了jackson 2.15.X。

您至少应该升级到最新的 2.X 版本（2.7.16），然后看看是否可以手动升级到 jackson 2.15.2

2.2.X 自 2020 年 10 月 16 日起停产 (https://spring.io/projects/spring-boot#support)
