    JVM Sandbox

    JVM Sandbox

    Real-time non-invasive AOP framework container based on JVM

    JVM sandbox container, a JVM non-invasive runtime AOP solution. Real-time non-invasive AOP framework container based on JVM. Dynamically enhance the class you specify, get the parameters and line information you want, and even change the method execution. JVM-SANDBOX (sandbox) implements an AOP solution that does not restart or invade the target JVM application. Static knitting occurs when the bytecode is generated, and the AOP bytecode is inserted into the target class and method in advance according to the rules of a certain framework to realize AOP. Dynamic knitting allows the AOP bytecode enhancement of the specified method to be completed during the JVM operation. Most common dynamic knitting schemes use renaming the original method, and then create a new method with the same signature to do the proxy work mode to complete The function of AOP (common implementation scheme such as CgLib), but there are some application boundaries in this way.
