Ⅰ. Introduction of zfoo🚩

• Extremely fast, asynchronous, actor design pattern, lock free, universal RPC framework, native GraalVM support
• Decentralized serialization zfoo protocol，supports C++ C# Go Java Javascript TypeScript Lua GDScript Python
• High scalability，Single server deployment, microservice deployment, cluster deployment, gateway deployment
• Can be used as a game server framework or website server framework.

Perfect work development process, complete online solution

• Spring projects, distributed projects, container projects， hot update code without downtime hotswap
• Excel json csv configuration is automatically mapped and parsed，Online hotswap configuration storage
• Automapping framework for MongoDB orm
• Event bus event
• Time task scheduling scheduler
• cpu, memory, hard disk, network monitoring built into the program no code and extra tools required monitor

Ⅱ. Who use this project

• Projects with extremely high performance requirements, such as website and game server frameworks, single server, global server, live chat, IM system, real-time push
• Projects such as saving, development, deployment, operation and maintenance costs
• As a backend infrastructure for Godot，Unity，Cocos，Webgl，H5，Network protocol supports tcp udp websocket http
• Keep it Simple and Stupid ，simple configuration, lightweight code

Ⅲ. Maven dependency✨

• Environment requirement JDK 17+, support OpenJDK, Oracle JDK and native GraalVM

<dependency>
    <groupId>com.zfoo</groupId>
    <artifactId>boot</artifactId>
    <version>3.2.0</version>
</dependency>

• If you don't want to depend all zfoo modules, you only need to choose to depend on one of them

<dependency>
    <groupId>com.zfoo</groupId>
    <artifactId>protocol</artifactId>
    <version>3.2.0</version>
</dependency>

Ⅴ. Usage⭐

1. protocol ultimate performance serialization and deserialization

// zfoo protocol registration, can only be initialized once
ProtocolManager.initProtocol(Set.of(ComplexObject.class, ObjectA.class, ObjectB.class));

// serialization
ProtocolManager.write(byteBuf, complexObject);

// deserialization
var packet = ProtocolManager.read(byteBuf);

2. net ultimate performance RPC framework, supports tcp udp websocket http

// Service provider, only need to add an annotation to the method, the interface will be automatically registered
@PacketReceiver
public void atUserInfoAsk(Session session, UserInfoAsk ask) {
}

// Consumers, synchronously requesting remote service, will block the current thread
var userInfoAsk = UserInfoAsk.valueOf(userId);
var answer = NetContext.getCosumer().syncAsk(userInfoAsk, UserInfoAnswer.class, userId).packet();

// Consumers, asynchronously requesting remote service, and will still execute logic in the current thread after the asynchronous
NetContext.getCosumer()
                    .asyncAsk(userInfoAsk, UserInfoAnswer.class, userId)
                    .whenComplete(sm -> {
                        // do something
                    );

3. hotswap hot update code, no need to stop the server, no additional configuration, just one line of code to start hot update

// Pass in the class file that needs to be updated
HotSwapUtils.hotswapClass(bytes);

4. orm automatic mapping framework based on mongodb，The secondary cache is designed using caffeine to fully release the database pressure

// You don't need to write sql and any configuration yourself, define a table in the database directly through annotation definitions
@EntityCache
public class UserEntity implements IEntity<Long> {
    @Id
    private long id;
    private String name;
}

// update database data
entityCaches.update(userEntity);

5. event use the observer design pattern, decouples different modules and improves the quality of the code

// To receive an event, you only need to add an annotation to the method and the method will be automatically listen for the event
@EventReceiver
public void onMyNoticeEvent(MyNoticeEvent event) {
    // do something
}

// fire an event
EventBus.post(MyNoticeEvent.valueOf("My event"));

6. scheduler scheduling Framework Based on Cron Expression

@Scheduler(cron = "0/1 * * * * ?")
public void cronSchedulerPerSecond() {
    // do something
}

7. storage Excel to class automatic mapping framework, you only need to define a class corresponding to Excel, and directly parse Excel

@Storage
public class StudentResource {
    @Id
    private int id;
    @Index
    private String name;
    private int age;
}
