1.下载Spring
spring3.x以后托管到github上，所以下载源码直接到github上去下载。
github地址：spring-framework
由于我编译的是最新的的版本 spring-framework-5.0.4.RELEASE
下载地址：
https://codeload.github.com/spring-projects/spring-framework/zip/v5.0.4.RELEAS
下载如下图：
2.下载Gradle编译
由于spring是采用Gradle编译，所以必须下载Gradle
下载地址 https://gradle.org/releases/
我下载的最新版本：https://gradle.org/next-steps/?version=4.6&format=bin
- 配置环境变量
添加：GRADLE_HOME
添加环境变量：Path：%GRADLE_HOME%in - 检测环境
gradle -v
