问题描述
我正在遵循 official documentation 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。
以下是代码片段。
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。应用启动成功后，我测试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，目标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，目标名称应与您在本地目录中创建的代码和 jco 目标中使用的名称相同。
[{name: "s4x011rfc"}]
解决方法
我们扩展了有关从本地计算机运行 BAPI 调用的文档。
我们添加了一个关于如何维护环境变量 destinations 的 section，它让 SAP Cloud SDK 找到目标名称。
