其他-使用 Cloud SDK Spring 原型在本地调用 BAPI 时找不到目的地

(其他 - The destination could not be found when calling BAPI locally with Cloud SDK Spring archetype)

发布于 2021-01-20 09:02:25

我正在按照官方文档在 SAP Cloud Platform 上和本地使用 Cloud SDK Spring 原型调用 BAPI。Cloud SDK 版本为 3.35.0。

它在提供 RFC 目标的 SAP Cloud Platform 上运行良好，但在本地找不到目标。我完成了文档中的所有步骤。

下面是代码片段。

public List<CostCenter> getCostCenters() {
        
        System.setProperty("jco.destinations.dir", "C:\\tools\\SAP\\destinationrfc");
        log.info(System.getProperty("jco.destinations.dir"));
        
        Destination destination = null;
        BapiRequestResult resultGetCostCenters = null;
        try {
            destination = DestinationAccessor.getDestination("s4x011rfc");
            log.info("Get destination successfully.");
            resultGetCostCenters = new BapiRequest("BAPI_COSTCENTER_GETLIST1")
                                       .withExporting("CONTROLLINGAREA", "BAPI0012_GEN-CO_AREA", "0010")
                                       .withTable("COSTCENTERLIST", "BAPI0012_CCLIST").end()
                                       .withTableAsReturn("BAPIRET2")
                                       .execute(destination);
            log.info("Get costcenters successfully.");
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
        
        log.info("Start to get results.");
        //ResultElement re = resultGetCostCenters.get(0);
    
        return resultGetCostCenters.get("COSTCENTERLIST").getAsCollection().asList(CostCenter.class);
    }

我在文件夹“C:\tools\SAP\destinationrfc”中创建了一个 rfc 目标文件，并在我的代码中设置了系统属性。

然后，我在 Eclipse 中使用 war 部署（集成了 Tomcat）启动了我的应用程序。应用程序启动成功后，我测试了REST API触发BAPI调用，得到如下异常。

更新

我对在环境变量中创建的目标进行了一些测试。它工作正常。除了文档中的配置外，目的地也应该在环境变量中创建。

目标定义在环境变量中非常简单。只需要目的地名称。请注意，目标名称应与你在本地目录中创建的代码和 jco 目标中使用的名称相同。

我们扩展了有关从本地计算机运行 BAPI 调用的文档。我们增加了一个章节就如何维护环境变量destinations它可以让SAP云SDK找到目的地名称。
