一、result:chain（从一个Action转发到另一个Action）
chain结果类型有4个属性，分别是：
actionName (default) - the name of the action that will be chained to
namespace - used to determine which namespace the Action is in that we're chaining. If namespace is null, this defaults to the current namespace
method - used to specify another method on target action to be invoked. If null, this defaults to execute method
skipActions - (optional) the list of comma separated action names for the actions that could be chained to
eg：
public String hotGoods() {
try {
QueryRule queryRule=QueryRule.getInstance();
queryRule.addEqual("isNew", "0");
List<ProductInfo> productInfoList = geProductInfoService.queryGeProductInfoByQueryRule(queryRule);
super.getRequest().setAttribute("productInfoList ", productInfoList );
}catch (Exception e) {
e.printStackTrace();
}
return SUCCESS;
}
<action name="hotGoods" class="listAction" method="hotGoods">
<result name="success" type="chain">hotGoods1</result>
</action
public String hotGoods1() {
try {
List<ProductInfo> productInfoList = (List<ProductInfo>)super.getRequest().getAttribute("productInfoList ");
super.getRequest().setAttribute("productInfoList ", productInfoList );
} catch (Exception e) {
e.printStackTrace();
}
return SUCCESS;
}
<action name="hotGoods1" class="listAction" method="hotGoods1">
<result name="success">index.jsp</result>
</action>
index.jsp可以得到productInfoList 的值
二、result:redirect（从一个Action转发到另一个Action）
public String getFamilyCardUrl() {
try {
familyCardWeixinURL = “*****”;
//familyCardWeixinURL内容为*****.getFamilyCardOpenId.do？code=code&****
return "familyCardWeixinURL";
} catch (Exception e) {
e.printStackTrace();
}
return "fail";
}
<action name="getFamilyCardOpenId" class="**Action" method="getFamilyCardOpenId">
<result name="familyCardWeixinURL" type="redirect">${familyCardWeixinURL}</result>
<result name="fail" type="redirect">/common/500Phone.jsp</result>
</action>
getFamilyCardOpenId所在action中需要有全局变量familyCardWeixinURL及其get，set方法
