我正在尝试构建一个用于云解决方案的应用程序。当尝试在本地运行应用程序时，出现错误:
java.lang.NoClassDefFoundError:
com/sap/cloud/sdk/odatav2/connectivity/ODataException.
它在 Java EE 7 Web Profile Tomee 7 服务器上运行。

服务器的本地目标已配置为 ErpQueryEndpoint。 Pom.xml 还包括用于 Odata 连接的 groupID 和 artifactId。包已导入。
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

最佳答案
正如我在您的代码中看到的，您正在查询 SAP S/4HANA 的自定义 OData 服务。对于对自定义 OData 服务的 OData 查询，您还可以考虑使用 Virtual Data Model (VDM) of the S/4HANA Cloud SDK而不是 ODataQueryBuilder。要将 VDM 与自定义 OData 服务结合使用，可以使用 VDM 生成器，如 following blog post 中所述。 。顺便说一句，它也适用于 S/4HANA On-Premise。您可以找到有关定制的更多详细信息here .
关于java - 尝试通过 Odata 服务连接时 ErpConfigContext 和 ODataQueryBuilder 抛出错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/55819331/
