Struts2一个很好例子.doc

HYPERLINK /blog/254099 第一个Struts2例子 关键字: struts2 今天开始学习一下struts2，做了第一个的struts2的程序。在官方网站下载了struts--all.zip。 然后在myeclips6中建立项目，导入包。整个目录如下： 导入几个基本的包: commons-logging-1.0.4.jar. freemarker-2.3.8.jar ognl-2.6.11.jar struts2-core-.jar xwork-2.0.2.jar 这些包在struts--all.zip中都有。注意的关键点是需要将这些包拷贝到WEB-INF的lib目录中。 配置web.xml web.xml Xml代码 ?xml?version=1.0?encoding=UTF-8??? web-app?version=2.4??? ????xmlns=/xml/ns/j2ee??? ????xmlns:xsi=/2001/XMLSchema-instance??? ????xsi:schemaLocation=/xml/ns/j2ee??? ????/xml/ns/j2ee/web-app_2_4.xsd?? filter?? filter-namestruts2/filter-name?? filter-classorg.apache.struts2.dispatcher.FilterDispatcher/filter-class?? /filter?? filter-mapping?? filter-namestruts2/filter-name?? url-pattern/*/url-pattern?? /filter-mapping?? /web-app?? 写LoginAction.java Java 代码 package?cn.redalx.struts2.study;?? ?? public?class?LoginAction?{?? ??private?String?username;?? ??private?String?password;?? public?String?getPassword()?{?? ????return?password;?? }?? public?void?setPassword(String?password)?{?? ????this.password?=?password;?? }?? public?String?getUsername()?{?? ????return?username;?? }?? public?void?setUsername(String?username)?{?? ????this.username?=?username;?? }?? public?String?execute()?throws?Exception??? {?? ????return?success;?? }?? }?????  配置struts.xml，注意一个问题，和struts1x不同，这个文件需要放到classes目录，即在myeclips中，应该放到src目录中。 Xml代码 ?xml?version=1.0?encoding=UTF-8???? !DOCTYPE?struts?PUBLIC?? ????-//Apache?Software?Foundation//DTD?Struts?Configuration?2.0//EN?? ????/dtds/struts-2.0.dtd?? struts?? package?name=struts2?extends=struts-default?? action?name=login?class=cn.redalx.struts2.study.LoginAction?? result/result.jsp/result?? /action?? /package?? /struts??? login.jsp页面 Html 代码 form?action=login.action?method=post?? ?username:input?type=text?name=username?br?? ?password:input?type=password?name=passwordbr?? ????input?type=submit?value=提交?? ????/formbr?? lt;!--?需 要注意，action的目标是login.ac
