| 项目使用的jackson版本为`2.12.5`，同时引入该项目和版本低于`2.5.x`的SpringBoot会有jackson兼容性问题。推荐升级SpringBoot到版本`2.5.x`及以上。如无法升级，可按照下述方式指定jackson版本。 | |||

- 具体原因应该讲得更清楚。首先是我们升级了jackson并使用了
2.11中的API。但是，其他组件依赖了低版本，自动引入产生了冲突。 - 建议升级Springboot版本时，建议补充原因，别人才愿意升级嘛

Gradle 的 G 也要大写，包括下面的 Maven

建议使用 < <= > >=来精确表达区间开闭，在点进去「官方已不再维护版本低于2.3.x的SpringBoot」这个链接之前，我是不太确定「低于2.3.x」是否包含2.3.x的。

这里是单独的dependencyManagement依赖管理块，这个块里只需声明一个依赖，所以不用说明顺序。依赖管理块与单独的dependencies是不相关的。

这段话感觉很生硬，应该使用对话式的语态，就像跟开发者说话那样。

因为项目升级了Jackson依赖，在代码中使用了版本>=2.11的API，当其他组件引用低版本的Jackson时会导致依赖冲突。例如版本<2.3.x的SpringBoot。由于官方已不再维护版本<2.3.x的SpringBoot，继续使用有风险，推荐开发者及时升级。如果由于特殊原因无法升级，可以按照下面的方式指定Jackson版本。
这样是否可以？
