创建ErpConfigContext抛出异常

Question

我试图使用S/4HANASDK调用CompanyCode OData VDM服务，但是如果在Cloud环境中这样做，则会得到附加错误。我以前一直在使用SDK，但这并没有发生。你能帮帮我吗？

代码：

public List<CompanyCode> findAll() {
    try {
        return compCodeService.getAllCompanyCode().execute(erp())
                .stream()
                .map(this::toCompCode)
                .collect(Collectors.toList());
    } catch (ODataException e) {
        throw SapException.create(e.getMessage());
    }
}

private ErpConfigContext erp(){
    return new ErpConfigContext(REPLICATE_WORKFORCE);
}

 public static final String REPLICATE_WORKFORCE = "REPLICATE_WORKFORCE";

错误：

Have you correctly configured a RequestContextServletFilter or have you wrapped your logic in a RequestContextExecutor when executing background tasks that are not triggered by a request?] with root cause

Answer 1

您能否确保在您的应用程序中获取RequestContextServletFilter？默认情况下，RequestContextServletFilter使用@WebFilter注释。

Spring示例：

@SpringBootApplication
@ServletComponentScan( "com.sap.cloud.sdk" )
public class Application extends SpringBootServletInitializer
{
    ...
}

另见：https://docs.spring.io/spring-boot/docs/current/api/org/springframework/boot/web/servlet/ServletComponentScan.html

编辑:注意，在后台作业中运行代码(不是由请求触发)时，必须使用RequestContextExecutor::execute包装代码。
