springboot 如何使用RequestConntextListener在子线程中获取request

Hello! 欢迎使用 ChitGPT 进行对话。对于您的问题，可以在子线程中获取 HttpServletRequest 对象的方法是使用 RequestContextHolder.getRequestAttributes() 方法。具体实现方式可以参考下面的代码：

@Component
public class CustomAsyncConfigurer implements AsyncConfigurer {

    @Override
    public Executor getAsyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(10);
        executor.setMaxPoolSize(20);
        executor.setQueueCapacity(30);
        executor.setThreadNamePrefix("ChitGPT-Executor-");
        executor.initialize();
        return executor;
    }

    @Override
    public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() {
        return new CustomAsyncExceptionHandler();
    }

    public static class CustomAsyncExceptionHandler implements AsyncUncaughtExceptionHandler {

        @Override
        public void handleUncaughtException(Throwable ex, Method method, Object... params) {
            // 异常处理逻辑
        }

    }

}

@Component
public class CustomTask implements Runnable {

    @Autowired
    private SomeService someService;

    @Override
    public void run() {
        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
        // 执行子线程逻辑
    }

}

@Controller
public class SomeController {

    @Autowired
    private CustomAsyncConfigurer customAsyncConfigurer;

    @RequestMapping("/some/request")
    @ResponseBody
    public String someRequest() {
        // 在 controller 中获取 HttpServletRequest 对象
        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();

        // 异步执行子线程逻辑
        Runnable task = new CustomTask();
        AsyncTaskExecutor executor = customAsyncConfigurer.getAsyncExecutor();
        executor.execute(task);

        return "success";
    }

}

以上代码演示了如何在子线程中获取 HttpServletRequest 对象，并通过 AsyncConfigurer 和 AsyncTaskExecutor 实现异步执行子线程逻辑的流程。希望对您有所帮助。
