第一步，配置 web.xml

[html] view plain copy print?

第二步，配置spring-mvc.xml

[html] view plain copy print?

<span style="font-size:18px;">
<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/**" />
<mvc:exclude-mapping path="/login.do" />
<bean class="com.cm.contract.controller.annotation.GEISSSessionTimeoutInterceptor"></bean>
</mvc:interceptor>
</mvc:interceptors>
</span>

第三步，写拦截器SystemSessionInterceptor 方法

[java] view plain copy print?

public class SystemSessionInterceptor implements HandlerInterceptor {
private static final String LOGIN_URL="/jsp/sessionrun.jsp";
@Override
public void postHandle(HttpServletRequest request,
HttpServletResponse response, Object handler,
ModelAndView modelAndView) throws Exception {
}
@Override
public void afterCompletion(HttpServletRequest request,
HttpServletResponse response, Object handler, Exception ex)
throws Exception {
}
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response,
Object handler) throws Exception {
HttpSession session=request.getSession(true);
//session中获取用户名信息
Object obj = session.getAttribute(CMConstant.LOGINUSER);
if (obj==null||"".equals(obj.toString())) {
response.sendRedirect(request.getSession().getServletContext().getContextPath()+LOGIN_URL;
return false;
}
return true;
}

第五步，配置友情提示页面sessionrun.jsp
