使用S/4 HANA SDK生成OData VDM导致错误

Question

我尝试为S/4 HANA Cloud提供的OData服务生成VDM (它不在API集线器中)。生成的VDM类显示错误，特别是它具有UUID set和get方法以及TRUE属性的错误。我在这里附加了元数据edmx.xml。

英

此XML文件似乎没有任何与其关联的样式信息。文档树如下所示。

Answer 1

原来问题是缺少Lombok配置。

由于这个问题被问了很多次，我将给出一个比“配置它”更全面的答案，回答最常见的问题。

Lombok是什么？

根据他们的website

Project Lombok是一个java库，它可以自动插入到您的编辑器和构建工具中，为您的java增色不少。永远不要再编写另一个getter或equals方法，只需使用一个注释，您的类就拥有了一个功能齐全的构建器，自动化了您的日志变量，等等。

更具体地说，Lombok允许您向代码添加注释，这将在编译时生成样板。

因此，以@EqualsAndHashCode为例:顾名思义，这将为带注释的类生成有效的equals(Object)和hashCode()方法。

有关注释的完整列表，请参阅overview page。

你用Lombok做什么？

我们在OData VDM生成器中使用以下注释(不是完整列表，将来也可能会更改)：

• @Builder
• @ToString
• @EqualsAndHashCode
• @Data

最后一个注释引入了@Getter注释，该注释在编译时生成所有必要的getter。

如何使用Lombok编译代码/在IDE中显示代码？

正如Lombok和我们的blog post直接描述的那样，您只需要在类路径上使用Lombok依赖项(org.projectlombok:lombok)和provided作用域。

要在您的集成开发环境中查看代码而没有任何构建问题，您需要相应地设置您的集成开发环境，请参阅Lombok guides。
