1.源码下载
下载链接:https://tomcat.apache.org/download-80.cgi#8.5.35
2.源码构建
2.1配置
-
解压缩: 首先idea编译器创建空项目tomcat_original,然后将源代码压缩包解答到该项目当前目录中;
- 配置:
- 进入解压缩文件目录下即D:\JetBrains\worksapce\tomcat_original,创建文件夹home,并将conf,wappers目录移到该文件夹中;
- 在tomcat源码目录下即D:\JetBrains\worksapce\tomcat_original\apache-tomcat-8.5.55-src,创建 pom.xml文件,引入tomcat依赖;
- pom文件中具体内容如下:注意改变artifactId标签的值

2.2源码导入
2.3启动源码
-
主启动类即main方法,路径:tomcat_original\apache-tomcat-8.5.55-src\java\org\apache\catalina\startup\Bootstrap.java
-
配置启动类:
- Vm options参数配置
-Dcatalina.home=D:/JetBrains/worksapce/tomcat_original/apache-tomcat-8.5.55-src/home
-Dcatalina.base=D:/JetBrains/worksapce/tomcat_original/apache-tomcat-8.5.55-src/home
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=D:/JetBrains/worksapce/tomcat_original/apache-tomcat-8.5.55-src/home/conf/logging.properties
- 启动过程中如果控制台日志存在乱码现象,则VM options中加入以下配置:
-Duser.language=en -Duser.region=US -Dfile.encoding=UTF-8
- 配置org.apache.jasper.servlet.JasperInitializer:
在tomcat的源码org.apache.catalina.startup.ContextConfig中的configureStart函数中手动将JSP解析器初始化:
context.addServletContainerInitializer(new JasperInitializer(), null);
protected synchronized void configureStart() {
// Called from StandardContext.start()
if (log.isDebugEnabled()) {
log.debug(sm.getString("contextConfig.start"));
}
if (log.isDebugEnabled()) {
log.debug(sm.getString("contextConfig.xmlSettings",
context.getName(),
Boolean.valueOf(context.getXmlValidation()),
Boolean.valueOf(context.getXmlNamespaceAware())));
}
webConfig();
//初始化,引入下面一行代码
context.addServletContainerInitializer(new JasperInitializer(), null);
if (!context.getIgnoreAnnotations()) {
applicationAnnotationsConfig();
}
if (ok) {
validateSecurityRoles();
}
。。。。
}

运行
将源码构建运行后,在浏览器输入http://localhost:8080,则成功进入tomcat的欢迎页面。
