SpringBoot源码搭建

---

源码下载

需要环境 ：

• JDK 1.8+
• Maven 3.5+
• Spring Boot 1.x.x: Gradle 版本建议为2.9或更高版本。
• Spring Boot 2.x.x: Gradle 版本建议为4.x.x或更高版本。

GitHub

从v2.3.x开始，SpringBoot开始强制用Gradle构建项目，如需使用maven搭建，可下载v2.2.13.RELEASE版本

这里下载并搭建windows版本

搭建

下载完成后解压,在解压目录下执行Maven项目构建命令：

mvn clean install -DskipTests -Pfast

会下载相关依赖的下载，稍等一会儿。
