Tomcat源码Idea maven启动

一、下载tomcat源码

https://github.com/apache/tomcat/tree/8.5.x

二、建立pom

编译可能有个测试类过不了。删除即可。

三、新建catalina-home目录

• 把webapp文件夹和conf文件夹copy到Catalina-home目录
• 新建空文件夹temp、log、lib

四，设置启动参数

-Dcatalina.home=catalina-home -Dcatalina.base=catalina-home -Djava.endorsed.dirs=catalina-home/endorsed -Djava.io.tmpdir=catalina-home/temp -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.util.logging.config.file=catalina-home/conf/logging.properties

 

  

• main class设置为 org.apache.catalina.startup.Bootstrap
• vm option复制上面的参数主要是设置Catalina的启动目录

 五、启动

 至此，tomcat已经成功启动。

六、访问tomcat

 

 

发现有NPE

解决：在Bootstrap中启动jasper，修改代码，在ContextConfig中加入如下代码

context.addServletContainerInitializer(new JasperInitializer(), null);

启动成功。
