前言：我们在使用A依赖的时候，这个依赖有引入了第三方B依赖，这时候我想指定B依赖的版本号

1. 解决示例

我想将 mysql、logback、tomcat 的版本升级到指定版本

只需在 pom.xml 文件的 properties 里面添加如下配置

<properties><java.version>1.8</java.version><maven-jar-plugin.version>3.1.1</maven-jar-plugin.version><!--指定springboot依赖的版本号--><!--将 mysql-connector-java-8.0.22 升级到 mysql-connector-java-8.0.27--><!--将 logback-classic-1.2.3.jar 升级到 logback-classic-1.2.9.jar--><mysql.version>8.0.27</mysql.version><mysql.version.databind>${mysql.version}</mysql.version.databind><logback.version>1.2.9</logback.version><logback.version.databind>${logback.version}</logback.version.databind><!--将 tomcat-embed-core-9.0.39.jar、tomcat-embed-websocket-9.0.39.jar 升级到 9.0.69--><tomcat.version>9.0.69</tomcat.version><tomcat.version.databind>${logback.version}</tomcat.version.databind></properties>

2. 完整pom示例
