Tom_No_01 IDEA tomcat 源码环境搭建

1.下载源码

  apache-tomcat-8.5.50-src

2.下载源码

  放D盘,解压后根目录新建pom.xml和catalina-home

pom.xml文件中内容为

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

  catalina-home中赋值根目录中的conf和webapps 还要新建空目录,如图

3.

编辑Configration

  1. 将apache-tomcat-8.0.53-src项目导入进IDEA中
  2. 配置启动参数

新建Application

Main class设置为org.apache.catalina.startup.Bootstrap

添加VM options 

-Dcatalina.home=D:\Tomcat_Study\apache-tomcat-8.5.38-src\catalina-home

说明:如果编译build的时候出现Test测试代码报错,注释该代码即可。本文中的Tomcat源码util.TestCookieFilter类会报错,将其注释即可。

4.启动报错

项目启动完毕我们可以测试了,在浏览器访问http://localhost:8080/  发现打不开我们看到的经典欢迎页面了,页面报了一个错

Unable to compile class for JSP

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);

修改完后,项目再启动,我们再在浏览器访问http://localhost:8080/ ,就可以看到我们所熟悉的经典欢迎页面了
