Introduction to openfire, spark, and smack

Openfire is an open-source Real-time Collaborative (RTC) server developed in Java based on the XMPP (jabber) protocol.

Smack is an XMPP client compiled in Java.CodeLibrary is the core of spark

There are always a lot of interesting things in the open-source world. These three are combined into a complete XMPP im implementation.

Openfire-server side

Spark -- Client

Smack-Implementation of XMPP transmission protocol

The three are implemented based on the Java language. XMPP is a protocol and the Protocol needs to be implemented. Smack plays such a role.

Openfire is an im-based server implementation based on XMPP protocol. Although two users can send messages in point-to-point mode after connection, however, you still need to connect to the server to obtain some connection information and communication information. Therefore, the server must be implemented.

Spark provides a basic implementation of the client and provides a good plug-in architecture. This is a good news for developers. I strongly recommend that you implement your new functions based on plug-ins instead of modifying them.Source codeThis helps your project architecture and minimize the impact of the original project.

Smack is a Java implementation of XMPP protocol and provides a set of scalable APIs. However, sometimes you still have to use your own custom XML file content to implement your own functions.

 

Relationship between the three:

It can be seen that both the client and server can be extended through plug-ins, and smack is the medium for both to transmit data.
