LifeRay Portal 6学习笔记6:使用Struts2开发Portlet

准备

Liferay版本：6.0.4

开发模式：普通插件模式（非Ext）

Struts版本：2.1.8.1

?

环境

使用到的Struts2相关jar包如下：

antlr-2.7.2.jar

commons-fileupload-1.2.1.jar

freemarker-2.3.15.jar

ognl-2.7.3.jar

struts2-core-2.1.8.1.jar

struts2-portlet-plugin-2.1.8.1.jar

xwork-core-2.1.6.jar

?

工程目录如下：

?

参考内容

参考Struts2自带的portlet示例struts2-portlet-2.1.8.1.war，在Struts解压包下面的apps目录里面，这个示例是基于Pluto（http://portals.apache.org/pluto/）Apache的Portal实现，但开发的都是portlet，所以可以参考这个。

开发示例代码

portlet.xml
