• 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"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0"

      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_Studyapache-tomcat-8.5.38-srccatalina-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
