發(fā)布時(shí)間：2024/4/17 编程问答 42 豆豆
生活随笔 收集整理的這篇文章主要介紹了 Struts2整合SiteMesh 小編覺(jué)得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

http://takeme.iteye.com/blog/1716488

1.導(dǎo)入Struts2的jar 和 sitemesh.jar 和 Struts2-sitemesh-plugin.jar?
commons-fileupload-1.2.2.jar?
commons-io-2.0.1.jar?
commons-lang3-3.1.jar?
commons-logging-1.1.1.jar?
freemarker-2.3.19.jar?
javassist-3.11.0.GA.jar?
ognl-3.0.5.jar?
sitemesh-2.4.2.jar?
struts2-core-2.3.4.jar?
struts2-sitemesh-plugin-2.3.4.1.jar?
xwork-core-2.3.4.jar?

2.在web.xml中配置 Struts sitemesh攔截器 注意有一定的順序?

Xml代碼??
