2.1 导入架包

Tomcat源码下下来后会少了几个架包，代码是会报错的：ant-1.6.5.jar、easymock-3.4.jar、jaxrpc-api-1.1.jar、ecj-4.6.1.jar、wsdl4j-1.6.2.jar、objenesis-2.2.jar、hamcrest-core-1.3.jar，可以手动下载这些架包，也可以通过maven的pom.xml导入，如下：

2.2 引入tomcat其他模块的架包：

从其他安装版本的tomcat里拷贝lib文件夹放到tomcat的根目录。

2.3 删除webapps里没有用的应用

3. 运行启动

源码启动Tomcat，是启动Bootstrap的main方法，其实startup.bat或者startup.sh也是启动Bootstrap的main方法。

3.1 配置Bootstrap

-Dcatalina.home=D:\workspace\apache-tomcat-9.0.20-src
-Dcatalina.base=D:\workspace\apache-tomcat-9.0.20-src
-Djava.io.tmpdir=D:\workspace\apache-tomcat-9.0.20-src\temp
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=D:\workspace\apache-tomcat-9.0.20-src\conf\logging.properties

3.2 启动Bootstrap

3.3 浏览器访问tomcat

http://localhost:8080/
