struts2配置Interceptor过滤器后在action中不能得到表单中的数据

表单
<form action="login" method="post">
用 户<input type="text" name="adminName">
密 码<input type="password" name="passwd">

<package name="myadmin" extends="struts-default">
<interceptors>
<interceptor name="checkAdmin"
class="daiyi.util.AdminInterceptor">
<param name="excludeMethods">login</param>
</interceptor>

<interceptor-stack name="myInterceptor">
<interceptor-ref name="defaultStack"/>
<interceptor-ref name="checkAdmin"/>
</interceptor-stack>
</interceptors>

<default-interceptor-ref name="myInterceptor"/>

<global-results>
<result name="login">adminLogin.jsp</result>
</global-results>

<global-exception-mappings>
<exception-mapping result="error"
exception="java.lang.NullPointerException"/>
</global-exception-mappings>

<action name="login" class="daiyi.action.AdminAction">
<interceptor-ref name="myInterceptor"/>
<result name="input">adminLogin.jsp</result>
<result name="success">admin/admin_index.jsp</result>
</action>

public class AdminAction extends ActionSupport{
private String adminName;
private String passwd;
省略set get

}

过滤器

public class AdminInterceptor extends MethodFilterInterceptor{
public void init(){

}

public String doIntercept(ActionInvocation aiv) throws Exception {

Map session=aiv.getInvocationContext().getSession();
AdminBean adminBean=(AdminBean)session.get("admin");

if (adminBean!=null) {
return aiv.invoke();

} else {
HttpServletRequest request=ServletActionContext.getRequest();
request.setAttribute("msg", "请重新登录");
return Action.LOGIN;
}
}

public void destroy(){

}
}

Answer 1

和我自己的相关文件比对了，没有问题，如果不能正常运行，建议加入一些打印语句，看一看运行情况，比如哪些方法执行没有啊什么的，见效比较快

Answer 2

确定数据放在session里了？
