SeaSar2之struts2+ seasar2 + s2dao框架整合-yellowcong
来源：互联网 发布：linux 内存查询 编辑：程序博客网 时间：2024/04/28 20:45
说起来，整合这个玩意还挺费事的，由于jar的不对，导致许多莫名奇妙的问题，其中Maven的jetty插件不支持jsp,需要自己配置，当时我就想骂人了，整体来说，整合的步骤基本是先Seasar2，然后s2dao，最后是struts，没啥难度，就是资料少，不好弄，淡腾，整合框架源码地址：https://git.oschina.net/yellowcong/seasar

我的数据库是mysql的，大家需要注意了，需要替换成自己的数据库版本

需要添加对Action的自动注入

基本没啥改动，就是数据库注意点

struts文件，需要注意的地方是，s2componentStack这个拦截器配置的时候，下面默认的拦截器，有些不好使，有可能是struts的版本问题，解决办法是看struts包下面的 struts-defualt.xml配置中的默认拦截器
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"><struts> <!-- 修改后缀名称 ，填写空，就表示去掉默认后缀操作--> <constant name="struts.action.extension" value=""/> <package name="default" extends="seasar-default"> <interceptors> <interceptor-stack name="s2componentStack"> <interceptor-ref name="alias" /> <interceptor-ref name="prepare" /> <interceptor-ref name="i18n" /> <interceptor-ref name="chain" /> <interceptor-ref name="s2component" /> <interceptor-ref name="modelDriven" /> <interceptor-ref name="fileUpload" /> <interceptor-ref name="staticParams" /> <interceptor-ref name="params" /> <interceptor-ref name="conversionError" /> <interceptor-ref name="validation"> <param name="excludeMethods"> input,back,cancel,browse </param> </interceptor-ref> <interceptor-ref name="workflow"> <param name="excludeMethods"> input,back,cancel,browse </param> </interceptor-ref> </interceptor-stack> </interceptors> <default-interceptor-ref name="s2componentStack" /> <action name="list" method ="list" class="com.yellowcong.action.UserAction"> <result type="velocity" name="success"> page/user/list.jsp </result> </action> </package></struts>struts-xx.jar包下面，有一个struts-defualt.xml配置文件，里面写了一堆默认的拦截器配置
