SpringBoot @Async如何自定义线程池及使用教程

@EnableAsync
@Configuration
public class AsyncConfiguration {
    //定义线程池
    @Bean("threadPool1") // bean的名称，线程池的bean的名字，不是创建线程的名字
    public Executor ThreadPool1(){
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(10); /** 核心线程数（默认线程数） */
        executor.setMaxPoolSize(20);/** 最大线程数 */
        executor.setQueueCapacity(500);/** 缓冲队列大小 */
        executor.setKeepAliveSeconds(60);/** 允许线程空闲时间（单位：默认为秒） */
        executor.setWaitForTasksToCompleteOnShutdown(true); 
        executor.setThreadNamePrefix("task-thread-"); /** 线程池名前缀 */
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.DiscardPolicy()); //拒绝策略：缓存队列满了之后由调用线程处理，一般是主线程
        executor.initialize();
        return executor;
    }
}

@RestController("/test")
public class Test2Controller {
    @Async("threadPool1")
    public void test1() throws InterruptedException {
        Thread.sleep(5000);
        System.out.println("test1");
    }
}

@Api("测试")
@RestController
@RequestMapping("/test/user")
public class TestController extends BaseController
{
    @Autowired
    private Test2Controller test2Controller;
    @ApiOperation("异步")
    @GetMapping("/testAsync")
    public String testAsync() throws InterruptedException {
        test2Controller.test1();
        return "async";
    }
}
