// @元器件公共类MyAppender扩展了AppenderSkeleton {

@Override
protected void append(LoggingEvent event) {
System.out.println("Peform Sending sns task here ........");

try {
    //Send to Sns or any other source
} catch (Exception e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
System.out.println("done sleeping");    
}

static{
    System.out.println("Loading MyAppender Class");
}

@Override
public void close() {
    // TODO Auto-generated method stub

}

@Override
public boolean requiresLayout() {
    // TODO Auto-generated method stub
    return false;
}

} // EOF MyAppender

公共类LoggingFilter扩展了OncePerRequestFilter {

@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response,
        final FilterChain filterChain) throws ServletException, IOException {


        filterChain.doFilter(request, response);


        System.out.println("Logging is Started From Filters >>>>>>>>>>>");

            logger.debug("This is my test Log Msg 1");
            logger.debug("This is my test Log Msg 2");
            logger.debug("This is my test Log Msg 3");
            logger.debug("This is my test Log Msg 4");
            logger.debug("This is my test Log Msg 5");

        System.out.println("Logging is Completed in Filters >>>>>>>>>>>");

} }

期望输出：记录从过滤器开始记录从过滤器

完成
