schedule request
时间: 2023-11-05 14:04:58 浏览: 217
在定时任务中获取request对象有两种方法。第一种方法是使用@Autowired注解来注入HttpServletRequest对象。但是需要注意的是,如果在非web请求的线程中使用该对象可能会抛出异常,因为没有与之关联的请求。第二种方法是通过在定时任务的执行方法中传递request对象作为参数来获取。这样可以确保在定时任务中能够正常访问request对象。

使用java编写Schedule超时重新请求
当使用Java编写一个能够处理超时并重新发送请求的调度程序时,可以使用`ScheduledExecutorService`和`Future`来实现。下面是一个简单的示例代码:
```java
import java.util.concurrent.*;
public class RequestScheduler {
private ScheduledExecutorService executor;
private int maxRetries;
private long timeout;
public RequestScheduler(int maxRetries, long timeout) {
this.maxRetries = maxRetries;
this.timeout = timeout;
this.executor = Executors.newSingleThreadScheduledExecutor();
}
public void scheduleRequest(Runnable requestTask) {
RetryTask retryTask = new RetryTask(requestTask);
executor.schedule(retryTask, 0, TimeUnit.MILLISECONDS);
}
private class RetryTask implements Runnable {
private Runnable requestTask;
private int retryCount;
public RetryTask(Runnable requestTask) {
this.requestTask = requestTask;
this.retryCount = 0;
}
@Override
public void run() {
Future<?> future = executor.submit(requestTask);
try {
future.get(timeout, TimeUnit.MILLISECONDS);
} catch (InterruptedException | ExecutionException | TimeoutException e) {
if (retryCount < maxRetries) {
System.out.println("Request timed out, retrying...");
retryCount++;
scheduleRequest(requestTask);
} else {
System.out.println("Max retries exceeded, request failed.");
}
}
}
}
public void shutdown() {
executor.shutdown();
}
public static void main(String[] args) {
RequestScheduler scheduler = new RequestScheduler(3, 5000); // 最多重试3次,超时时间为5秒
Runnable requestTask = new Runnable() {
@Override
public void run() {
// 执行您的请求任务
// 例如:发送HTTP请求等
}
};
scheduler.scheduleRequest(requestTask);
// 等待所有任务完成后关闭调度程序
scheduler.shutdown();
}
}
```
在上面的示例中,`RequestScheduler`类使用`ScheduledExecutorService`创建一个单线程的调度程序,并提供了`scheduleRequest`方法用于调度请求任务。`RetryTask`类是一个内部类,它实现了`Runnable`接口来执行请求任务。在`run`方法中,它使用`Future`来执行请求任务,并设置超时时间。如果超时或发生异常,它会根据重试次数和最大重试次数来判断是否重新调度请求任务。
您可以根据自己的需求调整`maxRetries`(最大重试次数)和`timeout`(超时时间)。在`main`方法中,创建一个`RequestScheduler`实例并调用`scheduleRequest`方法来示范使用。
希望这个示例能满足您的需求!如果您有任何问题,请随时提问。

考虑以下几点优化:
1. 将一些重复的代码抽象成函数,如创建MA任务、车端请求云端等,可以提高代码的复用性和可维护性。
2. 对于同步请求和移除异常MA任务的验证,可以使用pytest中的assert语句,使代码更加简洁易读。
3. 对于异步推送的验证,可以使用pytest中的fixture和mock,模拟推送结果,避免依赖实际的推送结果。
修改后的代码如下:
