Tomcat源码调试环境搭建

我们一般都是为了解决某个问题，才去看源码的。Java体系就是这点好处，源码唾手可得。遇到问题，最后的解决方法总是可以从源码中找到。

参考了网上的文章，过程整理如下：

1. 下载和导入

官网下载编译好的： apache-tomcat-8.5.12.zip 和对应的源码包：apache-tomcat-8.5.12-src.zip。

解压到当前文件夹，然后将 apache-tomcat-8.5.12 文件夹改名为：catalina-home

如下图：

然后在 apache-tomcat-8.5.12-src 目录下加入一个pom.xml文件，内容如下：

然后从 Ideal 导入 maven 项目apache-tomcat-8.5.12-src
