springboot 使用多线程

在Spring Boot中使用多线程可以有多种方式。

1. 继承Thread类

public class MyThread extends Thread {
    @Override
    public void run() {
        // 线程执行代码
    }
}

然后在Spring Boot中调用该线程：

MyThread thread = new MyThread();
thread.start();

2. 实现Runnable接口

public class MyRunnable implements Runnable {
    @Override
    public void run() {
        // 线程执行代码
    }
}

然后在Spring Boot中调用该线程：

MyRunnable runnable = new MyRunnable();
Thread thread = new Thread(runnable);
thread.start();

3. 使用线程池

@Configuration
@EnableAsync
public class AsyncConfig implements AsyncConfigurer {
 
    @Override
    public Executor getAsyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(10);
        executor.setMaxPoolSize(20);
        executor.setQueueCapacity(200);
        executor.setKeepAliveSeconds(60);
        executor.setThreadNamePrefix("MyExecutor-");
        executor.initialize();
        return executor;
    }
}

然后在Spring Boot中调用该线程池：

@Autowired
private Executor executor;

public void runTask() {
    executor.execute(new Runnable() {
        @Override
        public void run() {
            // 线程执行代码
        }
    });
}

以上是几种在Spring Boot中使用多线程的方式，具体选择哪种方式取决于实际业务需求和个人偏好。
