如何在SpringBoot项目中使用多线程提高处理性能?

import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@EnableAsync
public class MyApplication {
    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }
}

import org.springframework.scheduling.annotation.Async;
import org.springframework.stereotype.Service;

@Service
public class MyService {

    @Async
    public void performTask() {
        // 模拟长时间运行的任务
        try {
            Thread.sleep(5000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println("Task completed in thread: " + Thread.currentThread().getName());
    }
}

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;

@Configuration
public class AsyncConfig {

    @Bean
    public ThreadPoolTaskExecutor taskExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(10);
        executor.setMaxPoolSize(20);
        executor.setQueueCapacity(100);
        executor.setThreadNamePrefix("Async-");
        return executor;
    }
}

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class MyComponent {

    @Autowired
    private MyService myService;

    public void execute() {
        myService.performTask();
        System.out.println("Main thread continues...");
    }
}
