创建Action类tutorial.Login将role放到session中，并转到Action类tutorial.AuthorizatedAccess，代码如下：
package tutorial;
import java.util.Map;
import org.apache.struts2.interceptor.SessionAware;
import com.opensymphony.xwork2.ActionSupport;
public class Login extends ActionSupport implements SessionAware {
private String role;
private Map session;
public String getRole() {
return role;
}
public void setRole(String role) {
this .role = role;
}
public void setSession(Map session) {
this .session = session;
}
@Override
public String execute() {
session.put( " ROLE " , role);
return SUCCESS;
}
}
最后，配置struts.xml文件，内容如下：
<! DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd" >
< struts >
< include file ="struts-default.xml" />
< package name ="InterceptorDemo" extends ="struts-default" >
< interceptors >
< interceptor name ="auth" class ="tutorial.AuthorizationInterceptor" />
</ interceptors >
< action name ="Timer" class ="tutorial.TimerInterceptorAction" >
< interceptor-ref name ="timer" />
< result > /Timer.jsp </ result >
</ action >
< action name ="Login" class ="tutorial.Login" >
< result type ="chain" > AuthorizatedAccess </ result >
</ action >
< action name ="AuthorizatedAccess" class ="tutorial.AuthorizatedAccess" >
< interceptor-ref name ="auth" />
< result name ="login" > /Login.jsp </ result >
< result name ="success" > /ShowRole.jsp </ result >
</ action >
</ package >
</ struts >
