springMVC有三个映射器，如果不定义映射Mapping，那么就会使默认： l <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean> 也就是说：上面这个定义和不定义都是一样的。 不定义： <bean id="testController" name="/hello.do" class="cn.itcast.controller.TestController"></bean> 直接使用：hello.do来访问。 <!-- 简单的url映射处理器 --> l <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <props> 那么上面的这个映射配置：表示多个*.do文件可以访问多个Controller或者一个Controller。 前提是：都必须依赖： <bean id="testController" name="/hello.do" class="cn.itcast.controller.TestController"></bean> <!-- /WEB-INF/jsp/index.jsp --> <bean class="org.springframework.web.servl <prop key="/hello1.do">testController</prop> <prop key="/a.do">testController</prop> </props> </property> </bean> et.view.InternalResourceviewResolver"> <property name="prefix" value="/WEB-INF/jsp/"></property> <property name="suffix" value=".jsp"></property> </bean>

获取名字判断 然后判断他是不是三次没成功，在用户数据的数据库表中，加个字段 以记录今天的失败登陆次数目！ 再加个记录临时时间的字段~~~~~~~~！ 当一个用户当天登陆第一次的时候，自动更新时间字段里的时间数据，用语句实现只更新一次，如果时间字段里的数据与服务器系统时间相同就不更新了~~~~~~！《还有就是如果不是当天时间，还要在数据库中的记录数目的字段把数据刷成0，是当天时间就不刷````````！（因为这个时间不是今天的，就等于记录的昨天的失败登陆次数目）》 然后用户没登陆失败一次，找到自己对应的记录数目的字段，如果不为3，就增加+1！ 然后页面判断用户登陆页面的时候，找到他的记录数目的字段，判断是不是为3！如果为3便拒绝，不为3通过验证！（进行密码验证） “接到前面《》那里````````！” https://wenku.baidu.com/view/910e4614da38376bae1fae42.html?rec_flag=default 当会员登录后记录其登录时间（年、月、日、时、分、秒，按你需要的精确度来定）。下次会员登录的时候就将这个时间和他当前时间对比，如果小于24小时就提示用户说一天只能登录一次，然后退出，如果大于24小时，则将当前时间记录替换原来的时间，并让用户登录。 步骤如下： 1、在用户表里增加一个记录用户上次登录时间的字段。 2、用户登录后则对当前时间与数据库里用户上次登录时间进行比较。 3、对比较结果进行逻辑判断（是否大于24小时）从而决定接下来的操作。 比较结果>24小时，则让其登录。比较结果<24小时，则不让其登录。如果是等于的话就根据你自己的需要来编写代码了。

The contemporary view of the Smart City is very much static and infrastructure- centric, focusing on installation and subsequent management of Edge devices and analytics of data provided by these devices. While this still allows a more efficient management of the city’s infrastructure, optimizations and savings in different do- mains, the existing architectures are currently designed as single-purpose, vertically siloed solutions. This hinders active involvement of a variety of stakeholders (e.g., citizens and businesses) who naturally form part of the city’s ecosystem and have an inherent interest in jointly coordinating and influencing city-level activities.

One traditional view of how wireless networks evolve is of a continuous, inevitable progres- sion to higher link speeds, combined with greater mobility over wider areas. This standpoint certainly captures the development from first and second generation cellular systems focused on voice support, and the early short-range wireless data networks, through to today’s 3G cellular and mobile broadband systems; there is every confidence that the trend will continue some way into the future.

During the past decade, many wireless communication techniques have been developedto achievevariousgoals suchas higherdata rate,morerobustlink quality, and higher number of users in a given bandwidth. For wireless communication systems, depending on the availability of a feedback link, two approaches can be considered: namely open and closed loop. Open loop communication system that does not exploit the channel knowledge at the transmitter is now well understood from both a theoretical and practical point of view.

When digital media is perceived only as a tool to deliver content the potential for using its affordances to explore meaning is lost. Rather than seeing media only as an access point, we can view it as a way to enhance the expressiveness of content. Today blogs, wikis, messaging, mash-ups, and social media (Facebook, Twitter, YouTube and others) offer authors ways to create narrative meaning that refl ects our new media culture. We can look to the past for similarities and parallels to better understand how to use social media as a creative tool with which to dialogue, collaborate, and create interactive narratives.
