Spring专题一：源码编译

下载源码

因为公司使用的是Spring5.2.x所以就下载了这个版本，github源码地址如下：

GitHub - spring-projects/spring-framework at v5.2.6.RELEASE：

如果网络不稳定可以使用下载压缩版即可，网络稳定的话还是建议使用git clone 这样可以看到随时切换其他版本，查看不同版本提交记录：

配置Gradle

因为Spring源码编译下选择的是Gradle，所以需要配置本地环境，目前自己电脑用的mac版本，这里先使用Mac演示配置。后面有window电脑环境的时候再补充。

官网地址：

Gradle | ReleasesFind binaries and reference documentation for current and past versions of Gradle.https://gradle.org/releases/

下载完以后是一个压缩包

解压到本地目录：

去bin目录下执行下 gradle -v 检查下下载的文件是否有问题，如果如下所示则下载正确。

配置环境变量

# 配置gradle path
export GRADLE_HOME=/自己的全路径
export PATH=$GRADLE_HOME/bin:$PATH
# 配置生效
source ~/.bash_profile

类似java，我再上面直接贴命令了，执行上述命令以后随便进入一个目录再次执行gradle -v 看下配置的环境变量是否生效。

配置setting文件

配置阿里元仓库地址

仓库服务

配置Spring源码

配置文件调整

以下是对Spring源码导入IDEA前的Gradle配置调整的总结：

修改gradle.properties文件：
- 设置Spring版本号：version=5.2.6.RELEASE
- 增加Gradle编译时的内存分配：org.gradle.jvmargs=-Xmx2048M，这有助于处理较大的构建任务，减少内存不足的问题。
- 开启Gradle的缓存功能：org.gradle.caching=true，这可以提高构建速度，通过缓存避免重复编译。
- 开启Gradle并行编译：org.gradle.parallel=true，允许Gradle在多核处理器上并行执行任务，加快构建速度。
- 开启Gradle守护进程模式：org.gradle.daemon=true，这可以保持Gradle进程持续运行，减少启动时间。
调整settings.gradle文件：
- 通常这个文件用于指定项目根目录下的所有子项目，可能需要根据Spring源码的结构进行适当的修改，以确保所有模块都能正确识别和构建。
调整build.gradle文件：
- 这个文件定义了项目的构建逻辑，包括依赖项、插件和其他构建配置。根据Spring源码的具体需求，可能需要添加或修改依赖项和插件配置。

问题解决

如果下载的版本和我一样，都是5.2.6可能有个小问题，这个包可能下载，要不自己去仓库找到放到自己本地仓库中，或者直接注释掉

//  id 'io.spring.gradle-enterprise-conventions' version '0.0.2'

完整配置

嫌弃麻烦，可以直接我的配置应该就可以了。完成这些配置调整后，就可以将Spring源码导入IDEA，等待下载就完事。
