IDEA搭建tomcat源码过程

1. 访问tomcat官网

https://tomcat.apache.org/download-80.cgi 根据自己的系统选择源码下载

2 解压

3.解压后，在根目录新建 catalina-home 文件夹和一个pom文件。

pom.xml的文件内容：

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

4 .将外部的 webapps 和 conf 两个文件夹挪到这个文件夹下面，再新建 lib logs temp work 几个空文件夹

5.打开idea 导入项目，等待编译

6. JmxRemoteLifecycleListener 可能会报错，导入包

7.编译完成后，再编辑启动类

-Dcatalina.home=E:\spring\apache-tomcat-8.5.61-src\catalina-home

-Dcatalina.base=E:\spring\apache-tomcat-8.5.61-src\catalina-home

-Djava.endorsed.dirsE:\spring\apache-tomcat-8.5.61-src\catalina-home\endorsed

-Djava.io.tmpdirE:\spring\apache-tomcat-8.5.61-src\catalina-home\temp

-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager

-Djava.util.logging.config.fileE:\spring\apache-tomcat-8.5.61-src\catalina-home\conf\logging.properties

路径对应换成自己的
