struts2配置session超时,权限访问，异常日志等拦截器

1.Struts配置文件

2.SessionInterceptor超时拦截类

/**
 * <p>Description:session超时拦截</p>
 */
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import org.apache.struts2.StrutsStatics;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.interceptor.AbstractInterceptor;

public class SessionInterceptorextends AbstractInterceptor {

 private static final long serialVersionUID = 1L;

 @Override
 public String intercept(ActionInvocation ai) throws Exception {
  ActionContext actionContext = ai.getInvocationContext();
  //HttpServletResponse response = (HttpServletResponse) actionContext.get(StrutsStatics.HTTP_RESPONSE);
  HttpServletRequest request = (HttpServletRequest) actionContext.get(StrutsStatics.HTTP_REQUEST);
  HttpSession session = request.getSession();
  
  String path = request.getContextPath();
  String uri = request.getRequestURI();
  
  //如果是登录或注销，则不进行判断
  String loginAction = path+"/login_action";
  String loginoutAction = path+"/loginout.action";
  if(uri.startsWith(loginAction) || uri.startsWith(loginoutAction)){
   ai.invoke();
  }
  //session为空 或 登陆用户信息为空
  boolean empty = (session==null || session.getAttribute("LOGIN_USER_INFO")==null);
  if(empty){
   return "sessionTimeout";
  }
  return ai.invoke();
 }

}

注： 权限拦截类和session超时拦截类类似。
