Java.lang.Instrument Proxy Agent uses
The Java.lang.Instrument package was introduced in JDK5, and the programmer dynamically modifies the class code by modifying the bytecode of the method. This is typically done before the class's Main method invocation, which is implemented by specifying a proxy class for the class in Java. Invoking the Classfiletransformer transform method before the bytecode of the class is loaded into the JVM, enabling the abil

Briefly:Today, consider the active registration function of Zabbix.When you have 10 machines to monitor, it is no problem to add them manually. But what do you do when you have 50, hundreds, or more servers to monitor?Active agent Auto-registration is primarily used by agents to actively and automatically register with the Server. It is very good to solve the Agent IP, System, configuration is not uniform a
This blog will describe a usage scenario for dynamic proxies in Android applications.Proxy modeThe role of proxy mode is to provide a proxy for other objects to control access to this object.
