RMI (Remote Method Invocation) model is a kind of distributed object application. Using RMI technology, an object in one JVM can call an object method in another JVM and get the result of the call. The other JVM here can be on the same computer or on a remote computer. Therefore, RMI means that you need a Server side and a Client side.

Introduction to RMI Port

The Server side usually creates an object and makes it remotely accessible.

This object is called a remote object.

The Server side needs to register that this object can be accessed remotely by Client.

The Client side calls the methods on the objects that can be accessed remotely, and the Client side can communicate with the Server side and transmit information to each other.

At this point, it is found that it is very convenient to use RMI to build a distributed application. Like RPC, it can communicate with each other between distributed applications, and even is very similar to the current micro-service idea.

Advantages and disadvantages of RMI

Advantages: the ability to avoid repeating wheels

Disadvantages: the call process is slow, and the process is unreliable, prone to unexpected errors, such as network errors.
