Java EE is an abstract API. It exist of just contracts (as you see in javadocs), not concrete code. The application servers are the concrete implementations. So, if you're looking for the source, you should look at the application server vendor's homepage for a source code download link. However, you're unlucky with Weblogic. It is not open source. I've never used Weblogic (I am an open source fan), so I'm not sure if the source is provided along the Weblogic license, you might want to contact Weblogic support team. Other servers, like Tomcat, Glassfish, JBoss AS, etc are open source. WebSphere AS has also a "Community Edition" which is open source. You could grab the javax. API source code from any of them, but there is no guarantee that they are exactly the same as Weblogic uses. And still then, they do not provide the concrete Weblogic implementation code (like as the code in org.apache., com.sun. and org.jboss. packages in aforementioned open source servers).

所以想看J2EE源码，我只能假设你是想看Tomcat的具体实现（Glassfish、JBoss有各种的实现），
http://tomcat.apache.org/down... 搜索 Source Code，下载apache-tomcat-9.0.0.M17-src.zip，解压。
打开Intellij Idea => import project => 选择目录 => Create project from existing sources => next => next .... => finish
以上。
使用file-》open，接着一步一步下去，就可以了
