hm, slf4j supports MDC. dont know if it emulates it for logging impls
that dont support it or not.
here we use logback and have a thing like this:
public class RequestIdLogFilter implements Filter
{
private static final String MDC_REQUEST_ID = "requestId";
private static AtomicInteger requestIdCounter = new AtomicInteger();
public void init(FilterConfig filterConfig) throws ServletException
{
requestIdCounter.set(1000);
}
public void doFilter(ServletRequest request, ServletResponse
response, FilterChain chain)
throws IOException, ServletException
{
int id = requestIdCounter.getAndIncrement();
MDC.put(MDC_REQUEST_ID, String.valueOf(id));
try
{
chain.doFilter(request, response);
}
finally
{
MDC.remove(MDC_REQUEST_ID);
}
}
}
then in the log simply ${requestId} and it adds it to every logging line
