代码如上 该怎么访问它？路径怎么写？ 展开
struts.xml应该这么写：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd";>//这块必须写，要不然程序不知道是struts配置文件。不明白楼主为什么还要include一个struts-default.xml，你下面的package已经extends一个了。
<struts>
<package name="struts2_login" extends="struts-default" namespace="/">
<action name="checkLogin" class="act.LoginAction" method="checkLogin">
<result name="success">/index.jsp</result>
<result name="login">/login.jsp</result>
</action>
</package>
</struts>
action方法：
package act;
import com.opensymphony.xwork2.ActionSupport;
public class LoginAction extends ActionSupport{
@SuppressWarnings("unused")
public String checkLogin(){//方法必须为public的
System.out.println("asdad");
return SUCCESS;
}
}
刚才我运行了，成功，没有任何问题
