By default, the following properties will be set for all transports: <ul> <li>"handlerClass"</li> <li>"remoteAddress"</li> <li>"localAddress"</li> </ul> When <code>session.getTransportMetadata().getAddressType() == InetSocketAddress.class</code> the following properties will also be set: <ul> <li>"remoteIp"</li> <li>"remotePort"</li> <li>"localIp"</li> <li>"localPort"</li> </ul> User code can also add properties to the context, via If you only want the MDC to be set for the IoHandler code, it's enough to add one MdcInjectionFilter at the end of the filter chain. If you want the MDC to be set for ALL code, you should add an MdcInjectionFilter to the start of the chain and add one after EVERY ExecutorFilter in the chain<P><P><DL><DT><B>Version:</B></DT> <DD>$Rev: 566952 $, $Date: 2007-08-17 09:25:04 +0200 (vr, 17 aug 2007) $</DD><DT><B>Author:</B></DT> <DD>The Apache MINA Project (dev@mina.apache.org)</DD></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><A NAME="nested_class_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TH ALIGN="left" COLSPAN="2"><FONT SIZE="+2"><B>Nested Class Summary</B></FONT></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static class</CODE></FONT></TD>⌨️ 快捷键说明
