struts2事例程序 访问action失败 404错说是请求资源无效 后台也不报错

 <package name="main"  namespace="/" extends="struts-default">
 <action name="time_reference" class="com.jin.gzzd.Time_reference" method="execute">
 <result name="SUCCESS">index.jsp</result>
 </action>
 </package>

public class Time_reference {

return name;

public void setName(String name) {
this.name = name;

话说，你的action类没有居然没继承ActionSupport.将public class Time_reference {改成public class Time_reference extends ActionSupport {

为什么你导包了 居然没继承

一般使用struts2
返回视图名称都是SUCCESS常量(可以看Action接口的定义)，不是字符串
index.jsp

/index.jsp

<action name="time_reference.action"
