AbstractRequestLoggingFilter类定义了两个方法beforeRequest和afterRequest分别用于设定过滤前后执行的操作，它有三个子类，分别是CommonsRequestLoggingFilter、ServletContextRequestLoggingFilter和Log4jNestedDiagnosticContextFilter，这三个子类分别实现了各自的beforeRequest和afterRequest。其中，CommonsRequestLoggingFilter在过滤前后分别打印出一段debug的信息；ServletContextRequestLoggingFilter在过滤前后分别向日志文件中写入一段日志信息，日志文件可由log4j.properties等指定；Log4jNestedDiagnosticContextFilter则将日志信息存储到NDC中，NDC采用了一个类似栈的机制来push和pot上下文信息，每一个线程都独立地储存上下文信息，比如说一个servlet就可以针对 每一个request创建对应的NDC，储存客户端地址等信息。
