struts配置里:
<package name="default" namespace="/" extends="struts-default">
<action name="HelloWorld" class="HelloWorldAction">
<result name="success">/HelloWorld.jsp</result>
</action>
</package>
Action函数里:
public String execute() {
message="HelloWorld,Now is"
+ DateFormat.getDateInstance().format(new Date());
return SUCCESS;(此处没有引号)
}
页面调用时 <s:form action="HelloWorld" method="post">
<package name="default" namespace="/" extends="struts-default">
<action name="HelloWorld" class="HelloWorldAction">
<result name="success">/HelloWorld.jsp</result>
</action>
</package>
Action函数里:
public String execute() {
message="HelloWorld,Now is"
+ DateFormat.getDateInstance().format(new Date());
return SUCCESS;(此处没有引号)
}
页面调用时 <s:form action="HelloWorld" method="post">
