tomcat源码环境搭建

1.源码下载

进入tomcat 官网如下图

下载响应源码，如下图

2.环境搭建

在idea中新建空项目

解压刚刚下载的zip包至新建的项目中

在源码包中新建pom.xml文件，并配置相关插件及依赖

pom.xml配置如下

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

  </dependencies>
</project>

接着将tomcat源码模块引入至空项目中

然后配置启动class(其中main class的类路径为org/apache/catalina/startup/Bootstrap.java)

tomcat源码环境搭建

在虚拟机参数中设置相关配置路径,如果没有移动相关目录则配置如下

-Dcatalina.home=E:/IDEA-workspace/tomcat_project/apache-tomcat-8.5.42-src
-Dcatalina.base=E:/IDEA-workspace/tomcat_project/apache-tomcat-8.5.42-src
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=E:/IDEA-workspace/tomcat_project/apache-tomcat-8.5.42-src/conf/logging.properties

3.启动测试

启动application,并访问localhost:8080

访问报错

这是因为jsp解析器未被初始化，在org/apache/catalina/startup/ContextConfig#configureStart()中的webConfig();(770行)下面添加

context.addServletContainerInitializer(new JasperInitializer(),null);这时候重新启动main方法，并访问localhost:8080，展示正常页面
