springboot @async 线程自定义线程池
import java.util.Random;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.scheduling.annotation.Async;
import org.springframework.stereotype.Component;
import org.springframework.test.annotation.Commit;
/**

*/
@Component
public class Threads {
public static Random random = new Random();
Logger log = LoggerFactory.getLogger(Threads.class);
@Async("taskExecutor")
public void doTaskOne() throws Exception {
log.info("开始做任务一");
long start = System.currentTimeMillis();
Thread.sleep(random.nextInt(10000));
long end = System.currentTimeMillis();
log.info("完成任务一，耗时：" + (end - start) + "毫秒");
}
@Async("taskExecutor")
public void doTaskTwo() throws Exception {
log.info("开始做任务二");
long start = System.currentTimeMillis();
Thread.sleep(random.nextInt(10000));
long end = System.currentTimeMillis();
log.info("完成任务二，耗时：" + (end - start) + "毫秒");
}
@Async("taskExecutor")
public void doTaskThree() throws Exception {
log.info("开始做任务三");
long start = System.currentTimeMillis();
Thread.sleep(random.nextInt(10000));
long end = System.currentTimeMillis();
log.info("完成任务三，耗时：" + (end - start) + "毫秒");
}
}
2.直接调用就好
@RestController
public class ThreadController {
@Autowired
private Threads task;
@GetMapping("/aa")
public void test() throws Exception {
task.doTaskOne();
task.doTaskTwo();
task.doTaskThree();
Thread.currentThread().join();
}
}
springboot @async 使用Futrue以及定义超时加ThreadPoolTaskScheduler线程池的调用

@EnableAsync
@Configuration
class TaskPoolConfig {
@Bean("taskExecutor")
public Executor taskExecutor() {
ThreadPoolTaskScheduler executor = new ThreadPoolTaskScheduler();
executor.setPoolSize(20);
executor.setThreadNamePrefix("taskExecutor-");
return executor;
}
}

executor.setPoolSize(20);
executor.setThreadNamePrefix("taskExecutor-");
executor.setWaitForTasksToCompleteOnShutdown(true);
executor.setAwaitTerminationSeconds(60);
return executor;
}
