英文:
How springboot and maven maintain the dependency version?
问题
例如，我想升级jackson-databind版本。使用下面的pom.xml，版本升级到2.15.2，但是我没有定义jackson-databind的版本，只定义了jackson-bom.version。Spring Boot是如何维护它的？即使与Spring相关的jackson版本升级到2.15.2。
想了解原理。
英文:
For example, I want to upgrade the jackson-databind version. With below pom.xml, the version upgrade to 2.15.2, however I do not define the version of jackson-databind. Only define the jackson-bom.version. How springboot maintain it? Even related jackson version of spring upgrade to 2.15.2.
<parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>3.1.0</version></parent><properties><jackson-bom.version>2.15.2</jackson-bom.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId></dependency></dependencies>

BOM是一个特殊的POM文件，它将已知有效且经过测试可以一起使用的依赖版本进行分组 - Maven中的BOM。Jackson BOM包含了一套完整的一致版本的jackson依赖 - Jackson BOM。
英文:
The BOM is a special POM file that groups dependency versions that are known to be valid and tested to work together - BOM in maven. Jackson BOM contains a complete set of consistent versions of jackson dependencies - Jackson BOM
