## Ⅰ. Introduction of zfoo🚩

- **Extremely fast, asynchronous, actor design, lock free, universal RPC framework, native GraalVM support**
- High scalability, Single server deployment, microservice deployment, cluster deployment, gateway deployment
- Can be used as a game server framework or website server framework
- **[zfoo protocol](protocol/README.md) supports C++ Rust Java/Kotlin/Scala JavaScript/TypeScript/ES C# Go Php Ruby Lua GDScript Python Dart Swift**

Perfect work development process, complete online solution

- Spring projects, distributed projects, container projects, **hot update code without
  downtime** [hotswap](hotswap/src/test/java/com/zfoo/hotswap/ApplicationTest.java)
- Excel json csv configuration is automatically mapped and parsed, **Online hotswap
  configuration** [storage](storage/src/test/java/com/zfoo/storage/ApplicationTest.java)
- Automapping framework for MongoDB [orm](orm/README.md)
- Event bus [event](event/src/test/java/com/zfoo/event/ApplicationTest.java)
- Time task scheduling [scheduler](scheduler/README.md)
- **Cpu, memory, hard disk, network monitoring built into the program** no code and extra tools
  required [monitor](monitor/src/test/java/com/zfoo/monitor/ApplicationTest.java)

## Ⅱ. Who uses 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](https://baike.baidu.com/item/KISS原则/3242383), 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>4.1.4</version>
</dependency>
```

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

```
<dependency>
    <groupId>com.zfoo</groupId>
    <artifactId>protocol</artifactId>
    <version>4.1.4</version>
</dependency>
```

- [godot-bird](https://github.com/zfoo-project/godot-bird) bird and bird，powered by godot
- [FAQ](./doc/FAQ.md)，There are standard demo display and instructions in the test folder of each project directory,
  which can be run directly

## Ⅴ. Usage⭐

#### 1. [protocol](protocol/README.md) ultimate performance serialization and deserialization

```
// protocol registration
ProtocolManager.initProtocol(Set.of(ComplexObject.class, ObjectA.class, ObjectB.class));

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

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

#### 2. [net](net/README.md) 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 ask = UserInfoAsk.valueOf(userId);
var answer = NetContext.getCosumer().syncAsk(ask, UserInfoAnswer.class, userId).packet();

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

#### 3. [hotswap](hotswap/src/test/java/com/zfoo/hotswap/ApplicationTest.java) 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](orm/README.md) automatic mapping framework based on mongodb

```
// 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](event/src/test/java/com/zfoo/event/ApplicationTest.java) 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](scheduler/README.md) scheduling Framework Based on Cron Expression

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

#### 7. [storage](storage/src/test/java/com/zfoo/storage/ApplicationTest.java) 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;
}
```
