When using an existing method, you need to improve or modify the original method. At this time, there are two ways to improve: modify the original method to adapt to the current use method, or use a "third party" method to call the original method, and control the results of the method. The first method obviously violates the principle of "open to extension and disable to modify", and modifications to the original method may blur and diversify the functions of the original class, the second meth

clients of the cluster (the other way is LoadBalancer), so TargetportThe port on the pod, the service should proxy traffic to.Targetport well understood that Targetport is the port on the pod, and the data coming from port and Nodeport eventually go through the kube-proxy into the container on the targetport of the back-end pod.Port, Nodeport SummaryIn general, both port and Nodeport are service ports that

First, the server commonly used ports Each host (hosts) on the Internet has a unique address (IP), but the same host may provide more than one service, such as the FTP service, the WWW service, and so on, so that each service occupies one port of that host. The common ports used by proxy servers are: HTTP Proxy: 80/8080/3128/8081/9080 Socks Agent: 1080 FTP Agent: 21 Telnet Agent: 23 Second, how to sea

Java proxies include jdk dynamic proxies and cglib proxies. Here we only talk about jdk dynamic proxies. jdk dynamic proxies mainly use java reflection mechanisms (both java. lang. reflect packages) The principle is (examples of singers and agents ): Create a public interface, such as the Singer public interface Singer; Use a specific class to implement the interface. For example: Jay Chou, he is a Singer, so he implements the Singer class. class MySinger implements Singer Create a

why you use proxies. If we were a team developer, a class of the team might not want to be exposed to other callers. At this point, some of the functionality of the class is needed, and the best way is to provide it to the caller in a proxy way. For a drop-off user, It just needs to know that the classes that are provided to it can execute a business logic. It is completely unnecessary to know exactly who the real executor is. In addition, we can us
