本文介绍了一个Spring MVC应用中的拦截器实现案例，该拦截器用于统计客户端的访问记录，包括IP地址、访问路径及Cookie信息等，并将这些信息存储到数据库中。此外，还实现了针对特定URL模式的访问计数功能。

在spring配置文件中配置拦截器

<mvc:interceptors>
<bean class="aaaHandlerInterceptor"/>
</mvc:interceptors>

public class aaaHandlerInterceptor implements HandlerInterceptor {

@Autowired
private LogsService logsService;
private static List<List<LogsOuter>> logsList = null;
private static int logsPoint = 0;
private static final int listSize = 1;
private static final int everyListSize = 1;
private static final int accessRecordSize = 1;

/**
* 主要用于统计访问次数和点击率
*
* @param request
* @param response
* @param object
* @return
* @throws Exception

@Override
