Tomcat8.5源码环境搭建

1.下载apache-tomcat-8.5.50-windows-x64.zip和apache-tomcat-8.5.50-src.zip，解压。
2.在apache-tomcat-8.5.50-src根目录下放入pom.xml，内容：

            </plugin>
        </plugins>
    </build>
 
</project>

3.在idea中导入apache-tomcat-8.5.50-src，在Run/Debug Configurations配置Application（JRE选Default）：

4.将test/util/TestCookieFilter.java中的内容全部注释。

5.运行org.apache.catalina.startup.Bootstrap的main方法启动。

6.浏览器访问http://localhost:8080

注，之前调试代码在apache-tomcat-8.5.50-src根目录下有一个文件Tomcat8.5.iml，作用未知，记录在此，内容：
