struts2开发步骤

1.添加struts2的jar文件
commons-fileupload-1.2.2.jar
commons-io-2.0.1.jar
commons-lang-2.5.jar
commons-logging-1.1.1.jar
freemarker-2.3.16.jar
javassist-3.11.0.GA.jar
ognl-3.0.1.jar
struts2-core-2.x.x.jar
xwork-core-2.x.x.jar
2.在web.xml中配置struts2核心过滤器
<!-- 配置struts2核心过滤器 -->
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
3.编写业务逻辑XxxAction和页面
4.在src下新建struts.xml,并配置Action
<struts>
<!-- struts2的常量 -->
<!-- 解决乱码问题:默认UTF-8 -->
<constant name="struts.i18n.encoding" value="UTF-8"></constant>
<!-- struts2的后缀名 -->
<constant name="struts.action.extension" value="do,action"></constant>
<package name="user" extends="struts-default">
<!-- 全局跳转结果 -->
<global-results>
<result name="login">index.jsp</result>
</global-results>
<!-- {1}代表的userAction_*中的*对应的通配符的值 -->
<action name="userAction_*" class="com.xasxt.action.UserAction" method="{1}">
<result>success.jsp</ result>
</action>
</package>
</struts>
