Tomcat 7中的org.apache.catalina.ServerFactory.getServer()等价物

Question

org.apache.catalina.ServerFactory.getServer()Tomcat 7中的等价物或者检索org.apache.catalina.Session实例的最佳方法是什么？

以下是用于处理Tomcat 6.0的示例代码:

public List<org.apache.catalina.Session> findActiveSessions() throws ServiceException {
    StandardEngine engine = (StandardEngine) ServerFactory.getServer().findService("Catalina").getContainer();
    StandardContext  context = (StandardContext) engine.findChild(engine.getDefaultHost())
        .findChild(ServletActionContext.getServletContext().getContextPath()); 
    List<org.apache.catalina.Session> list = new ArrayList<org.apache.catalina.Session>();
    for (org.apache.catalina.Session session : context.getManager().findSessions()) {
        list.add(session);
    }
    return list;
}

Answer 1

您可以通过其管理注册查找..

import javax.management.*;
import org.apache.catalina.Server;

MBeanServer mBeanServer = MBeanServerFactory.findMBeanServer(null).get(0);
ObjectName name = new ObjectName("Catalina", "type", "Server");
Server server = (Server) mBeanServer.getAttribute(name, "managedResource");

显然,代码没有错误检查但功能正常.
