下载源码

下载地址 ：https://tomcat.apache.org/download-80.cgi#8.5.35

• 下载之后解压缩

导入Idea

添加pom.xml文件

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

直接启动main方法控制台会报错，且显示中文乱码

修改配置

需要我们配置启动类

-Dcatalina.home=D:/original/apache-tomcat-8.5.70-src
-Dcatalina.base=D:/original/apache-tomcat-8.5.70-src
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=D:/original/apache-tomcat-8.5.70-src/conf/logging.properties
-Duser.language=en
-Duser.region=US
-Dfile.encoding=UTF-8

改完设置后成功启动

打开浏览器输入： http://localhost:8080/

我们需要配置

• 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);

成功配置！！！
