tomcat8关键性源码分析

tomcat8的连接配置如下：

    <Executor name="tomcatThreadPool" namePrefix="catalina-exec-"               maxThreads="1000"         minSpareThreads="100"         prestartminSpareThreads =  "true"         maxQueueSize = "100"       />

<Connector port="8080" protocol="org.apache.coyote.http11.Http11Nio2Protocol"          connectionTimeout="30000"        redirectPort="8443"         maxConnections="2000"        executor="tomcatThreadPool"        enableLookups="false"        acceptCount="100"        maxPostSize="-1"           compression="on"                 disableUploadTimeout="true"           compressionMinSize="2048"           noCompressionUserAgents="gozilla, traviata"           acceptorThreadCount="2"           compressableMimeType="text/html,text/xml,text/plain,text/css,text/javascript,application/javascript"           URIEncoding="utf-8"      />

protocol用的是：org.apache.coyote.http11.Http11Nio2Protocol，如果配置protocol="HTTP/1.1"就是用的

org.apache.coyote.http11.Http11NioProtocol

，源代码如下，在Connector类中的Connector的构造方法：

    public Connector(String protocol) {        boolean aprConnector = AprLifecycleListener.isAprAvailable() &&                AprLifecycleListener.getUseAprConnector();        if ("HTTP/1.1".equals(protocol) || protocol == null) {            if (aprConnector) {                protocolHandlerClassName = "org.apache.coyote.http11.Http11AprProtocol";            } else {                protocolHandlerClassName = "org.apache.coyote.http11.Http11NioProtocol";            }        } else if ("AJP/1.3".equals(protocol)) {            if (aprConnector) {                protocolHandlerClassName = "org.apache.coyote.ajp.AjpAprProtocol";            } else {                protocolHandlerClassName = "org.apache.coyote.ajp.AjpNioProtocol";            }        } else {            protocolHandlerClassName = protocol;        }

Executor中的maxThreads和maxConnections是在AbstractProcotol中，如下：

    public int getMaxThreads() { return endpoint.getMaxThreads(); }    public void setMaxThreads(int maxThreads) {        endpoint.setMaxThreads(maxThreads);    }    public int getMaxConnections() { return endpoint.getMaxConnections(); }    public void setMaxConnections(int maxConnections) {        endpoint.setMaxConnections(maxConnections);    }

到此为止，server.xml中相关的配置就通过源码解释完毕了。
