the producer never sends any messages directly to a queue. Actually, quite often the producer doesn&#8217;t even know if a message will be delivered to any queue at all.<\/span>\n\t<\/p>\n<p style=\"box-sizing:border-box;margin-top:0px;margin-bottom:0px;word-break:break-word;line-height:1.7;\">\n\t\t<span style=\"font-size:14px;\">Instead, the producer can only send messages to an exchange. An exchange is a very simple thing. On one side it receives messages from producers and the other side it pushes them to queues. The exchange must know exactly what to do with a message it receives. Should it be appended to a particular queue? Should it be appended to many queues? Or should it get discarded. The rules for that are defined by the exchange type.<\/span>\n\t<\/p>\n<\/blockquote>\n<p style=\"box-sizing:border-box;margin-top:0px;margin-bottom:25px;word-break:break-word;color:#2F2F2F;font-family:-apple-system, &quot;font-size:16px;white-space:normal;background-color:#FFFFFF;\">\n\t<span style=\"font-size:14px;\">exchange\u662f\u4e00\u4e2a\u6d88\u606f\u7684agent\uff0c\u6bcf\u4e00\u4e2a\u865a\u62df\u7684host\u4e2d\u90fd\u6709\u5b9a\u4e49\u3002\u5b83\u7684\u804c\u8d23\u662f\u628amessage\u8def\u7531\u5230\u4e0d\u540c\u7684queue\u4e2d\u3002<\/span>\n<\/p>\n<h2 style=\"box-sizing:border-box;font-family:-apple-system, &quot;line-height:1.7;color:#2F2F2F;margin:0px 0px 15px;font-size:24px;text-rendering:optimizeLegibility;white-space:normal;background-color:#FFFFFF;\"><span class=\"ez-toc-section\" id=\"i-4\"><\/span>\n\t<span style=\"font-size:14px;\">binding\uff1f<\/span><br \/>\n<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"box-sizing:border-box;margin-top:0px;margin-bottom:25px;word-break:break-word;color:#2F2F2F;font-family:-apple-system, &quot;font-size:16px;white-space:normal;background-color:#FFFFFF;\">\n\t<span style=\"font-size:14px;\">exchange\u548cqueue\u901a\u8fc7routing-key\u5173\u8054\uff0c\u8fd9\u4e24\u8005\u4e4b\u95f4\u7684\u5173\u7cfb\u662f\u5c31\u662fbinding\u3002\u5982\u4e0b\u56fe\u6240\u793a,X\u8868\u793a\u4ea4\u6362\u673a\uff0c\u7ea2\u8272\u8868\u793a\u961f\u5217\uff0c\u4ea4\u6362\u673a\u901a\u8fc7\u4e00\u4e2arouting-key\u53bbbinding\u4e00\u4e2aqueue\uff0crouting-key\u6709\u4ec0\u4e48\u4f5c\u7528\u5462\uff1f\u770bDirect exchange\u7c7b\u578b\u4ea4\u6362\u673a\u3002<\/span>\n<\/p>\n<div class=\"image-package\" style=\"box-sizing:border-box;padding-bottom:25px;width:700px;margin-left:-40px;text-align:center;color:#2F2F2F;font-family:-apple-system, &quot;font-size:16px;white-space:normal;background-color:#FFFFFF;\">\n\t<img decoding=\"async\" src=\"http:\/\/upload-images.jianshu.io\/upload_images\/1055570-c0e2a2fed8380b12.png?imageMogr2\/auto-orient\/strip%7CimageView2\/2\" data-original-src=\"http:\/\/upload-images.jianshu.io\/upload_images\/1055570-c0e2a2fed8380b12.png?imageMogr2\/auto-orient\/strip%7CimageView2\/2\" style=\"box-sizing:border-box;vertical-align:middle;max-width:100%;height:auto;cursor:zoom-in;transition:all 0.25s ease-in-out;\" \/><br style=\"box-sizing:border-box;\" \/>\n<\/div>\n<h3 style=\"box-sizing:border-box;font-family:-apple-system, &quot;line-height:1.7;color:#2F2F2F;margin:0px 0px 15px;font-size:22px;text-rendering:optimizeLegibility;white-space:normal;background-color:#FFFFFF;\"><span class=\"ez-toc-section\" id=\"i-5\"><\/span>\n\t<span style=\"font-size:14px;\">Directed Exchange<\/span><br \/>\n<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"box-sizing:border-box;margin-top:0px;margin-bottom:25px;word-break:break-word;color:#2F2F2F;font-family:-apple-system, &quot;font-size:16px;white-space:normal;background-color:#FFFFFF;\">\n\t<span style=\"font-size:14px;\">\u8def\u7531\u952eexchange\uff0c\u8be5\u4ea4\u6362\u673a\u6536\u5230\u6d88\u606f\u540e\u4f1a\u628a\u6d88\u606f\u53d1\u9001\u5230\u6307\u5b9arouting-key\u7684queue\u4e2d\u3002\u90a3\u6d88\u606f\u4ea4\u6362\u673a\u662f\u600e\u4e48\u77e5\u9053\u7684\u5462\uff1f\u5176\u5b9e\uff0cproducer deliver\u6d88\u606f\u7684\u65f6\u5019\u4f1a\u628arouting-key add\u5230 message header\u4e2d\u3002routing-key\u53ea\u662f\u4e00\u4e2amessgae\u7684attribute\u3002<\/span>\n<\/p>\n<pre class=\"hljs vbnet\" style=\"box-sizing:border-box;overflow:auto;font-family:Menlo, Monaco, Consolas, &quot;font-size:13px;padding:15px;margin-top:0px;margin-bottom:20px;line-height:1.42857;word-break:break-word;word-wrap:normal;color:#657B83;background:#F6F6F6;border:1px solid #CCCCCC;border-radius:0px;text-size-adjust:none;\"><code class=\"vbnet\" style=\"box-sizing:border-box;font-family:Menlo, Monaco, Consolas, &quot;font-size:12px;background-color:transparent;border-radius:0px;padding:0px;border:none;\">A direct exchange delivers messages <span class=\"hljs-keyword\" style=\"box-sizing:border-box;color:#859900;\">to<\/span> queues based <span class=\"hljs-keyword\" style=\"box-sizing:border-box;color:#859900;\">on<\/span> a message routing <span class=\"hljs-keyword\" style=\"box-sizing:border-box;color:#859900;\">key<\/span>.
