创建 ErpConfigContext 抛出异常

Question

我正在尝试使用 S/4HANA SDK 调用 CompanyCode OData VDM 服务，但如果我在 Cloud Foundry 环境中执行此操作，则会收到附加错误。我之前一直在使用 SDK，但这并没有发生。你能帮我一下吗？

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：

 [Request processing failed; nested exception is com.sap.cloud.sdk.cloudplatform.tenant.exception.TenantAccessException: Failed to get current tenant: no RequestContext available. 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

您能否尝试确保 RequestContextServletFilter 在您的应用程序中被选中？ RequestContextServletFilter 默认使用 @WebFilter 注解。

Spring 引导示例：

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

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

编辑：请注意，当运行你的代码在后台作业（不是由请求触发）时，你必须用 RequestContextExecutor::execute.
