Spring Boot3.x集成Disruptor4.0

Spring Boot 3.x 整合 Disruptor 4.0 的示例代码如下：

1. 添加 Maven 依赖：

<dependencies>
    <!-- Spring Boot Starter -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>
 
    <!-- Disruptor 依赖 -->
    <dependency>
        <groupId>com.lmax</groupId>
        <artifactId>disruptor</artifactId>
        <version>4.0.0</version> <!-- 请确保使用Disruptor 4.0的最新版本 -->
    </dependency>
 
    <!-- 单元测试依赖 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

2. 创建一个事件类：

public class MyEvent {
    private long value;
 
    public long getValue() {
        return value;
    }
 
    public void setValue(long value) {
        this.value = value;
    }
}

3. 创建事件工厂和事件消费者：

public class MyEventFactory implements EventFactory<MyEvent> {
    @Override
    public MyEvent newInstance() {
        return new MyEvent();
    }
}
 
public class MyEventHandler implements EventHandler<MyEvent> {
    @Override
    public void onEvent(MyEvent event, long sequence, boolean endOfBatch) {
        // 处理事件的逻辑
        System.out.println("Event value: " + event.getValue());
    }
}

4. 配置 Disruptor 并启动：

import com.lmax.disruptor.dsl.Disruptor;
import com.lmax.disruptor.RingBuffer;
import com.lmax.disruptor.EventFactory;
 
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
 
@Configuration
public class DisruptorConfig {
 
    @Bean
    public Disruptor<MyEvent> disruptor() {
        int bufferSize = 1024;
        Disruptor<MyEvent> disruptor = new Disruptor<>(MyEvent::new, bufferSize, TaskExecutors.getDaemonThreadFactory());
        disruptor.handleEventsWith(new MyEventHandler());
        return disruptor;
    }
 
    @Bean
    public RingBuffer<MyEvent> ringBuffer(Disruptor<MyEvent> disruptor) {
        return disruptor.start();
    }
}

5. 使用 Disruptor 发布事件：

import com.lmax.disruptor.RingBuffer;
 
@Service
public class MyEventPublisher {
 
    private final RingBuffer<MyEvent> ringBuffer;
 
    @Autowired
    public MyEventPublisher(RingBuffer<MyEvent> ringBuffer) {
        this.ringBuffer = ringBuffer;
    }
 
    public void onData(MyData data) {
        long sequence = r
