天乙社区8.5.0Beta2
一、简介：
天乙社区是一套基于JAVA技术的网络虚拟社区，采用了Hibernate+Spring+Struts的轻量级J2EE框架.
1、全文检索：天乙社区6.0采用Lucene全文检索，并支持完全国际化多语言的全文检索。
2、MVC框架：天乙社区6.0继续了5.x的Struts框架，但经过优化，WEB端更加简洁高效。
3、集群支持：系统可以运行在集群上。
4、功能方面：大大加强了管理功能，用户可以多样化的定制系统的各项信息，包括用户级别、封锁IP、过滤字等等，论坛功能上主要增加了投票帖、上传附件类型多样、帖子中显示用户信息等等功能等。

二、功能分析：
1.web.xml：
在web.xml文件中，定义的filter和listener是有顺序的，涉及到对象的初始化顺序以及引用。特别注意的有如下几个配置：
Spring配置文件：
<context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext.xml,/WEB-INF/action-servlet.xml</param-value> </context-param>
<servlet> <servlet-name>authimg</servlet-name> <servlet-class>com.laoer.bbscs.web.servlet.AuthImg</servlet-class> </servlet> <servlet-mapping> <servlet-name>authimg</servlet-name> <url-pattern>/authimg</url-pattern> </servlet-mapping>
