以编程方式设置Tomcat的jvmRoute可以通过修改Tomcat的配置文件来实现。具体步骤如下:
<Engine name="Catalina" defaultHost="localhost">
...
<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster">
<Manager className="org.apache.catalina.ha.session.DeltaManager" expireSessionsOnShutdown="false" notifyListenersOnReplication="true"/>
<Channel className="org.apache.catalina.tribes.group.GroupChannel">
<Membership className="org.apache.catalina.tribes.membership.McastService" address="228.0.0.4" port="45564" frequency="500" dropTime="3000"/>
<Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver" address="auto" port="4000" autoBind="100" selectorTimeout="5000" maxThreads="6"/>
<Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter">
<Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>
</Sender>
<Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>
<Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/>
</Channel>
<Valve className="org.apache.catalina.ha.tcp.ReplicationValve" filter=""/>
<Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>
<ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>
</Cluster>
...
</Engine>
<Engine name="Catalina" defaultHost="localhost">
...
<Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true">
...
<Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>
...
</Host>
...
</Engine>
通过以上步骤,我们成功地以编程方式设置了Tomcat的jvmRoute。这样可以实现Tomcat集群中的会话复制和负载均衡,提高系统的可用性和性能。
