我正在尝试使用 @Scheduled 注释运行一个函数。反过来，调用存储库保存。但是保存失败并出现 InvalidDataAccessApiUsageException。发布我的堆栈跟踪。

org.springframework.dao.InvalidDataAccessApiUsageException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.; nested exception is java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread?

我在 web.xml 中添加了“RequestContextListener”。并使用java（以编程方式）进行所有配置。

// 调用调度程序的类。 

@Scheduled(cron = "0 0/5 * 1/1 * *")
public void processTask() {
    saveEntity();
}

//服务

public saveEntity(){
Media media = new Media();
//setting values to media
media = fieldMediaRepository.save(media);
}

//实体类

class Media{

    private String property1;
    private String property1;
    private String property1;

    @PostPersist
    public void postPersist() {
        (AuditService)AuditService.getContext().getBean("AuditService");
    }
}

//审计服务类

class AuditService{
    public static WebApplicationContext getContext() {
        if (context == null) {
            ServletRequestAttributes sessAttributes =
                    (ServletRequestAttributes)RequestContextHolder.currentRequestAttributes();
            context =
                    WebApplicationContextUtils                            .getWebApplicationContext(sessAttributes.getRequest().getServletContext());
        }
        return context;
    }
}

看起来您是在 Springs 上下文之外运行代码。您的 @Scheduled 方法无权访问 Spring 上下文中的 Repository。

创建具有 @Scheduled 方法的类，即 Spring 组件。您可以在配置中创建 bean 条目，也可以@Component为您的类使用注释。这应该这样做。

无需在 web.xml 中使用“RequestContextListener”。

该代码可能很有用，但堆栈跟踪告诉我您正在尝试使用 RequestContextHolder 访问请求。

这里的问题可能是 RequestContextListener 将请求绑定到 CURRENT 线程。而您正试图在其他线程中访问它（因为调度程序创建了其他线程）。
