Let's start with the simplest zoom tool to implement the common tools for map manipulation. Less nonsense, first on the code 1: using System;

The Java servlet, as the preferred server-side data processing technology, is rapidly replacing CGI scripts. One of the advantages of servlet beyond CGI is that not only can multiple requests share common resources, but it can also preserve persistent data between different user requests. This paper introduces a practical technique to give full play to this feature, that is, the database connection pool. The significance of realizing connection pool Dynamic Web sites often generate Web pages

That is to say, network-vif-plugged event to trigger, must be notified by Ovs-agent Neutron-server.Under normal circumstances, how does this process happen, we observe through the following experiment.Experiment 2 Under normal circumstances, the occurrence and processing of network-vif-plugged when the virtual machine is created.(1) The Nova-compute of the compute node waits for commands suc
