用Cloud为S4HANA BAPI调用定义SCP目标

Question

我正在寻找一种方法来调用S4HANA的前提BAPI本地和SAP平台上的Cloud。问题是如何像HTTP目的地一样定义RFC目的地。

我还遇到了JCo类，没有找到异常，也找不到合适的解决方法。

局部

在HTTP目的地中，我可以提供环境变量，如下所示：

set destinations=[{name: "destName", url: "URL", username: "username", password: "password"}]

但尚不清楚如何定义RFC目的地，这些属性与jco属性一样是强制性的。

SCP云铸造

我在SAP平台上创建了一个RFC目的地。

但是，我无法找到一种方法来装饰这个目的地，以便在Cloud中包含其他属性，就像HTTP目的地一样。

Destination destination = DestinationAccessor.getDestination(destName);
destination.asHttp().decorate(DefaultErpHttpDestination::new);  

请注意，当我进行洗礼调用，RfcDestination是不可接受的，只有类型目的地是必需的。RfcDestination不是接口目标的实现类。

​

JCO类未找到异常

java.lang.NoClassDefFoundError: com/sap/com/JCo/JCo

在使用带有Spring引导的时，存在一个已知的问题。我手动添加了jar文件subjco3.jar到项目类路径中。但还是没起作用。

更新

JCO类在运行时未找到异常

1. 你是正确的。我在SCP上部署了应用程序，然后调用我提供的rest来调用S4HANA的BAPI。然后我在运行时得到了这个异常。
2. 我正在使用Spring应用程序。
3. Spring项目由SAP原型生成。
4. 请参阅下面的错误堆栈跟踪。
5. 右键单击我的项目->构建路径->配置生成路径->选择库选项卡->添加外部jars
6. 我把我的应用程序部署为Jar文件。

我想强调的一件事是，SAP提供的官方文档说：“不可能在Spring 中使用Spring”。

带有非弹簧引导应用程序的SAP连接器

我创建了一个基于SAP原型的新项目，scp-cf，并试图调用洗礼。JCo问题已经解决了--我想，但在调用Bapi时，我得到了一个新的附加项“用户信息没有设置”。有人有类似的问题，但似乎还没有解决办法。

装饰目的地

我同意你的解释。也许它不需要作为Http目的地来做。但是，由于SAP Java连接器的问题，我陷入了困境。

本地RFC目标定义

实际上，我不知道RFC目的地需要哪些属性。如果我只使用HTTP，我将得到http状态404和服务未找到异常。

Answer 1

更新:查看最新的SAP关于BAPI调用的文档。

感谢你的更新。根据原始问题中的最新信息进行回答。再次检查每一个单独的标题。

JCO类在运行时未找到异常

只有在使用Spring的“传统部署”时才能使用Java连接器，它涉及构建和部署war文件，而不是jar文件。

带有非弹簧引导应用程序的SAP Java连接器

Java连接器的使用需要一个受保护的后端和一个应用程序路由器。我假设您没有使用它，这是由错误消息User Information is not set指示的。

装饰目的地

已应答

本地RFC目标定义

据我所知，从本地部署中使用Java连接器是不可预见的。为此，您必须将应用程序部署到SAP云平台上。关于在RFC目标上设置哪些属性的问题，您可以参考Java类DestinationDataProvider的Javadoc，您可以在从https://support.sap.com/jco下载后从JCo归档中提取它。

Answer 2

谢谢你在这里提出这个问题。我可以在你的问题中找出不同的方面，因此分别在以下几个方面进行讨论。

JCO类未找到异常

请提供有关下列问题的更多资料：

• 据我所知，在应用部署到SCP之后，您在运行时会收到一个java.lang.NoClassDefFoundError: com/sap/conn/jco/JCo。我的理解正确吗？
• 我知道您使用了Spring应用程序，对吗？
• 您使用过SDK原型吗？
• 请在此附上申请日志，以供进一步参考。
• 您还可以详细说明如何向项目类路径中添加subjco3.jar吗？
• 您是将应用程序部署为jar还是war？

通过环境变量创建RFC目的地

我知道您很难理解如何在您的环境变量中指定RFC目的地。请问您已经分别尝试了哪些具体问题(错误信息等)？你要面对吗？

不能对RFC目标进行修饰以涉及其他属性。

您正确地指出，考虑到HTTP目标上的附加属性，SDK能够丰富请求头。因此，您需要将您的HttpDestination实例装饰如下：

Destination destination = DestinationAccessor.getDestination(destName);
destination.asHttp().decorate(DefaultErpHttpDestination::new);  

我理解你的问题，RFC目的地如何同样的工作。据我判断，SAP提供的Java (JCO)库无论如何都会查看目标属性。因此，在RFC目的地范围内，我不认为有必要这样做。要求你更精确地描述你的需求，以防你不同意。

BapiRequest接受目的地，而不是RfcDestination

我理解您的问题，您感到惊讶的是，BapiRequest::execute确实期望一个Destination，而不是RfcDestination。然而，乍一看，这确实令人惊讶，因为supports也支持将BAPI包装为SOAP。这是通过HttpDestination实现的。对于具体的用例，只需使用DestinationAccessor.getDestination("xyz")并将返回值传递给execute方法即可。你不需要担心其他的事情。
