Maven / Gradle的Spring Boot？ (Spring Boot With Maven/Gradle?)

Spring Boot Framework uses one of the greatest features of Maven/Gradle build tools: “Transitively Dependency Resolution Management”.

Spring Boot Framework使用Maven / Gradle构建工具的最大功能之一： “传递依赖项解析管理” 。

什么是“传递依赖性解决方案管理”？ (What is “Transitively Dependency Resolution Management”?)

“Transitively Dependency Resolution Management” means: If we define an “A” dependency in build scripts, “A” is dependent on “B” and “B” is dependent on “C”, That means “A” is also dependent on “C”.
Then Build Tools will download and add all Three Jar files “A”, “B” and “C” to our application classpath.

“传递依赖项解决方案管理”的意思是：如果我们在构建脚本中定义“ A”依赖项，则“ A”依赖于“ B”，而“ B”依赖于“ C”，这意味着“ A”也依赖于“ C”。
然后，构建工具将下载所有三个Jar文件“ A”，“ B”和“ C”并将其添加到我们的应用程序类路径中。
