Service 内的 Spring @Async 方法

使用Spring的@Async方法实现异步服务

java
@Service
public class EmailService {
    @Async
    public void sendEmail(String to, String subject, String content) {
        // 模拟发送邮件的耗时操作
        try {
            Thread.sleep(5000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println("发送邮件给：" + to);
        System.out.println("主题：" + subject);
        System.out.println("内容：" + content);
    }
}

java
@Configuration
@EnableAsync
public class AppConfig {
    
    // 配置线程池
    @Bean
    public Executor asyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(5);
        executor.setMaxPoolSize(10);
        executor.setQueueCapacity(25);
        executor.initialize();
        return executor;
    }
}
