//jsp页面获取ActionMapping

request.setAttribute(Globals.MAPPING_KEY, mapping);//MAPPING_KEY = "org.apache.struts.action.mapping.instance";

//jsp页面获取ActionForm：一

request.setAttribute(mapping.getAttribute(), instance);/*public String getAttribute() {if (this.attribute == null) {  return (this.name);} else {  return (this.attribute);}}*/

//jsp页面获取ActionForm：二

request.getAttribute(org.apache.struts.taglib.html.Constants.BEAN_KEY)

//该方法只能用在struts标签中，例如:

<html:form>request.getAttribute(org.apache.struts.taglib.html.Constants.BEAN_KEY);</html:form>

org.apache.struts.taglib.html.FormTag源代码

doStartTag()：pageContext.setAttribute(Constants.BEAN_KEY, bean, PageContext.REQUEST_SCOPE);doEndTag():pageContext.removeAttribute(Constants.BEAN_KEY, PageContext.REQUEST_SCOPE);

//struts填充参数用到的方法

BeanUtils.populate(bean, properties);
