我需要停止然后以编程方式启动https连接器。 在tomcat 6中,以下代码段可以正常工作:
final ObjectName objectNameQuery = new ObjectName("*:type=Connector,port=443,*");
MBeanServer mbeanServer = null;
ObjectName objectName = null;
for (final MBeanServer server : (List<MBeanServer>) MBeanServerFactory.findMBeanServer(null))
{
if (server.queryNames(objectNameQuery, null).size() > 0)
{
mbeanServer = server;
objectName = (ObjectName) server.queryNames(objectNameQuery, null).toArray()[0];
break;
}
}
// now we restart the connector that we just found. We sleep a little, but I am
// not actually sure 1) how long we should sleep for or 2) if sleeping is
// necessary at all.
if (mbeanServer != null)
{
mbeanServer.invoke(objectName, "stop", null, null);
Thread.sleep(waitForStopInSec * 1000);
mbeanServer.invoke(objectName, "start", null, null);
log.warn("https Connector was restarted");
}
但是在tomcat 7(7.0.23)中,连接器没有停止!所以我使用这行代码调用了destroy()方法(在调用stop()方法之后): mbeanServer.invoke(objectName,“destroy”,null,null);
在这种情况下,连接器确实已停止。但是当我尝试启动它时,连接器没有启动,我得到了这个例外:

关于如何在tomcat 7中停止然后启动连接器的任何想法?优雅地以优雅的方式。 提前致谢, 盖

这取决于你如何定义“停止”。默认情况下,Tomcat在init()期间绑定到端口并在destroy()期间解除绑定。在默认情况下,stop()只是停止处理新连接,但它可能无法停止正在进行的连接(取决于 - 除其他外 - 底层操作系统)。
如果为server.xml中的连接器设置bindOnInit =“false”,则可能会获得更好的结果。使用此设置,当调用stop()时调用start()为未绑定时,将绑定端口。
