A <CODE>MessageConsumer</CODE> object is created by passing a <CODE>Destination</CODE> object to a message-consumer creation method supplied by a session. <P><CODE>MessageConsumer</CODE> is the parent interface for all message consumers. <P>A message consumer can be created with a message selector. A message selector allows the client to restrict the messages delivered to the message consumer to those that match the selector. <P>A client may either synchronously receive a message consumer's messages or have the consumer asynchronously deliver them as they arrive. <P>For synchronous receipt, a client can request the next message from a message consumer using one of its <CODE>receive</CODE> methods. There are several variations of <CODE>receive</CODE> that allow a client to poll or wait for the next message. <P>For asynchronous delivery, a client can register a <CODE>MessageListener</CODE> object with a message consumer. As messages arrive at the message consumer, it delivers them by calling the <CODE>MessageListener</CODE>'s <CODE>onMessage</CODE> method. <P>It is a client programming error for a <CODE>MessageListener</CODE> to throw an exception.<P><P><DL><DT><B>Version:</B></DT> <DD>1.0 - 13 March 1998</DD><DT><B>Author:</B></DT> <DD>Mark Hapner, Rich Burridge</DD><DT><B>See Also:</B><DD><A HREF="../../javax/jms/QueueReceiver.html" title="interface in javax.jms"><CODE>QueueReceiver</CODE></A>, <A HREF="../../javax/jms/TopicSubscriber.html" title="interface in javax.jms"><CODE>TopicSubscriber</CODE></A>, <A HREF="../../javax/jms/Session.html" title="interface in javax.jms"><CODE>Session</CODE></A></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/jms/MessageConsumer.html#close()">close</A></B>()</CODE><BR> Closes the message consumer. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../javax/jms/MessageListener.html" title="interface in javax.jms">MessageListener</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/jms/MessageConsumer.html#getMessageListener()">getMessageListener</A></B>()</CODE><BR> Gets the message consumer's <CODE>MessageListener</CODE>.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/jms/MessageConsumer.html#getMessageSelector()">getMessageSelector</A></B>()</CODE><BR> Gets this message consumer's message selector expression.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../javax/jms/Message.html" title="interface in javax.jms">Message</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/jms/MessageConsumer.html#receive()">receive</A></B>()</CODE><BR> Receives the next message produced for this message consumer. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../javax/jms/Message.html" title="interface in javax.jms">Message</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/jms/MessageConsumer.html#receive(long)">receive</A></B>(long timeout)</CODE><BR> Receives the next message that arrives within the specified timeout interval. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../javax/jms/Message.html" title="interface in javax.jms">Message</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/jms/MessageConsumer.html#receiveNoWait()">receiveNoWait</A></B>()</CODE><BR> Receives the next message if one is immediately available.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/jms/MessageConsumer.html#setMessageListener(javax.jms.MessageListener)">setMessageListener</A></B>(<A HREF="../../javax/jms/MessageListener.html" title="interface in javax.jms">MessageListener</A> listener)</CODE><BR> Sets the message consumer's <CODE>MessageListener</CODE>. </TD></TR></TABLE> <P><!-- ============ FIELD DETAIL =========== --><!-- ========= CONSTRUCTOR DETAIL ======== --><!-- ============ METHOD DETAIL ========== --><A NAME="method_detail"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY="">⌨️ 快捷键说明
