这篇文章记录了下载spring源码和在IDEA中打开运行的全过程，并且记录了过程中遇到的问题和解决方案，适合需要学习spring源码的同学阅读。

1.spring源码下载地址

通过Git下载spring-framework项目源码：

git clone https://github.com/spring-projects/spring-framework.git

2.使用IDEA构建spring-framework源码

笔者用的IDEA版本是社区版IDEA：IntelliJ IDEA 2020.34(Community Edition)，用IDEA打开源码后，IDEA会自动加载Gradle项目依赖。

然后这里就遇到了第一个问题：

2.1 SSL证书验证不通过（无该问题可跳过）

2.1.2 编译InstallCert .java

javac InstallCert.java

2.1.3 运行InstallCert，生成jssecacerts文件

--输入命令（域名换成自己idea访问报错的域名或者ip）
java InstallCert ge.spring.io:443

命令执行后，会要求输入数字1，生成证书文件

出现如下信息就代表安装成功

2.1.4 将同目录下生成的jssecacerts文件添加到$JAVA_HOME/jre/lib/security

2.1.5 重启IDEA（注意重启，不然可能不会生效）

这个问题这样就解决啦！

不过又出现了新的问题😂

2.2 KotlinConventions类编译失败

2.2.1 问题原因

https://www.cnblogs.com/haoxianrui/p/16975079.html

笔者本地使用了jdk8，而spring源码现在已经使用了jdk 17，所以我本地的jdk不适用于spring-framework，需要重新下载jdk17

2.2.2 下载使用jdk 17

Java JDK下载与安装教程

安装之后，在Gradle设置里，使用我们下载的jdk17

问题解决

Connection resetPossible solution:- Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

这个要排除下是网络问题还是代理问题

先使用ping命令看下网络是不是通的
