Springboot之@EnableAsync

1.@EnableAsync可以让Spring启用异步方法执行,跟配置注解@Configuration结合
2.使用的时候@Async加上方法的Bean名称
下面的例子是访问test/thread的URL时候可以看到先在网页上打印，然后过了5000个单位的时间后控制台才输出，实现了简单的线程池例子

Controller

@Controller
@RestController
@RequestMapping("test")
public class ThreadController {

    @Autowired
    private ThreadService threadService;

    @RequestMapping("thread")
    @ResponseBody
    public String RunTH()
    {
        threadService.Threadss();
        return "the page is showing but the console is not";
    }
}

线程配置类

@Configuration
@EnableAsync
public class ThreadConfig {
    @Bean("taskExecutor")
    public Executor myThreadExetor()
    {
        ThreadPoolTaskExecutor threadPoolTaskExecutor=new ThreadPoolTaskExecutor();
        threadPoolTaskExecutor.setCorePoolSize(5);//核心线程数量
        threadPoolTaskExecutor.setMaxPoolSize(20);//最大线程数量
        threadPoolTaskExecutor.setKeepAliveSeconds(60);//线程闲置的时候存活的时间
        threadPoolTaskExecutor.setThreadNamePrefix("baoliang_test");
        threadPoolTaskExecutor.initialize();
        return  threadPoolTaskExecutor;
    }
}

Service

@Service
public class ThreadServiceImpl implements ThreadService {
    @Override
    @Async("taskExecutor")
    public void Threadss() {
        try {
            Thread.sleep(5000);
            System.out.println("runinggggg~~~~~~~~~~~~~~~~");
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

    }
}

interface

public interface ThreadService {
    public void Threadss();
}
