tomcat源码运行

tomcat各版本下载地址:

https://archive.apache.org/dist/tomcat/

下载8.0.11的tomcat src包并解压，一开始的我参照的tomcat源码里BUILDING.txt进行编译运行，

安装了ant,在编译的时候遇到ssl的如下报错

尝试了去修改tomcat的server.xml里的Connector,然而ant编译一直不成功。

最后发现其实下载的源码做个小改动就可以直接在IDE里进行运行调试了，完全不需要使用ant来编译

上面的问题如果有高手看到能帮忙解答下最好啦

1.在源码的解压目录里添加pom.xml

2.通过File-->Open将源码导入到idea中 

3.在源码目录下创建catalina-home目录，复制webapps和conf到该目录下

4.创建Application

5.启动tomcat

访问发现提示如下错误:

原因是我们直接启动org.apache.catalina.startup.Bootstrap的时候没有加载org.apache.jasper.servlet.JasperInitializer，从而无法编译JSP。解决办法是在tomcat的源码org.apache.catalina.startup.ContextConfig中手动将JSP解析器初始化：

context.addServletContainerInitializer(new JasperInitializer(), null);

这样就可以正常访问了
