1.下载源码

环境：jdk版本1.8
官网源码下载tomcat8地址：http://tomcat.apache.org/download-80.cgi

2.解压下载的两个压缩包

1、apache-tomcat-8.5.45-src.zip（源码）解压为apache-tomcat。
2、apache-tomcat-8.5.45-windows-x64.zip（安装包）解压为apache-tomcat-8.5.45-windows-x64。
3、将tomcat安装压缩包解压文件apache-tomcat-8.5.45-windows-x64下的lib文件夹复制到tomcat源码压缩包解压文件apache-tomcat下的apache-tomcat\webapps\ROOT\WEB-INF路径下

3.新建pom.xml文件

在apache-tomcat目录下右击新建文件pom.xml

pom.xml文件内容：

4.eclipse导入tomcat源码

1、打开eclispe点击file ->import ->Existing Maven Projects 选择apache-tomcat文件夹。
注意：eclipse显示test文件夹会报错（有把小红叉），不用管，不影响启动。

apache-tomcat

5.启动tomcat

找到Bootstrap.java文件，右击Run As ->JavaApplication等待tomcat启动完成

6.验证tomcat是否启动成功

在浏览器中打开http://localhost:8080/（tomcat默认端口是8080）

7.手动发布项目到tomcat

zjhy.war是打包好的java-web项目（私人项目暂不提供），将zjhy.war复制粘贴到apache-tomcat\webapps文件夹下，等待tomcat自动将zjhy.war解压

8.验证启动的tomcat项目是否成功发布zihy这个java-web项目

在浏览器中输入http://localhost:8080/zjhy/echarts6.html然后回车，能正常打开刚才发布的项目说明项目发布成功。
