<!-- 此属性可用来解决乱码问题，每个版本的utf-8属性是不一样的 -->
<!-- constant主要用来设置常量配置比如加载，乱码，自定义后缀名等 -->
<!-- <constant name="struts.action.extension" value="action,,user"></constant>也可以用来设置自定义后缀名例如此句，他的配置的值可以在struts-scorejar中的org.apache.struts2.default文件中-->
<!-- 联习package和include

chain 这个结果类型代表action链,执行完actionA后执行actionB,地址栏是不变的
dispatcher 想当于servlet将后台的数据携带到需要显示的地方,默认的
<result name="success">/hi.jsp</result>

redirect 重定向action时地址栏会变,一直未懂
redirectAction 重定向到另一个action
<result name="success" type="chain">index</result>
<result name="success" type="redirectAction">index</result>
-->
<!--<global-results>定义全局结果集
<result name="success">/success.jsp</result>
</global-results>-->
<!--<default-class-ref class="com.struts2.action.Execution"></default-class-ref>
<default-action-ref name="hi"></default-action-ref>
<default-interceptor-ref ></default-interceptor-ref> 配置全局默认值 -->
