一、tomcat8源码下载地址

• 下载地址：https://tomcat.apache.org/download-80.cgi

二、tomcat8源码下载步骤

• 下载二进制包和源码包，如下图：

• 将下载的tomcat8源码包和二进制包解压，如下图：

三、idea导入tomcat8源码步骤

• 将解压后的tomcat8源码包和二进制包解压放到tomcat8目录下，如下图：

• idea中导入apache-tomcat-8.5.81-src源码工程

• 在源码目录下新建pom文件，pom文件内容如下：

• 点击pom.xml文件，点击【Add as Maven Project】,如下图：

• 至此，idea导入tomcat8源码包完成。如下图所示：
