无法加载 servlet 过滤器类：com.sap.cloud.sdk.cloudplatform.security.servlet.HttpSecurityHeadersFilter (SCP Neo)

Question

我来寻求帮助解决我在 SCP 中部署应用程序时遇到的问题。

SAP 云平台：

• SCP 环境为 Neo
• 运行时名称 = Java EE7 Web Profile TomEE 7
• 版本 = 1.74

Java 应用程序：

• 原型 Neo
• SAP Cloud SDK v3

应用程序日志如下：

另外，依赖树：

该应用在使用运行时版本 1.0 时（更新前）没有显示任何问题。 我使用的是 sdk-bom 版本 3.11.0 。我更新了 3.16.1 版本的 sdk-bom，但没有效果。

使用完全相同原型的其他两个应用程序（SAP Cloud SDK v2 除外）在 SCP 中部署时不会出现错误。

另外，如果在本地服务器（本地 Neo）中运行，也不会出现这样的错误。

您能否就如何解决这个问题给出提示？

BR，

Answer 1

我猜你的应用程序使用了后端保护，对吧？

com.sap.cloud.sdk.cloudplatform.security.servlet.HttpSecurityHeadersFilter 类包含在 Maven 工件中

<dependency>
  <groupId>com.sap.cloud.sdk.cloudplatform</groupId>
  <artifactId>security-servlet</artifactId>
</dependency>

因此，请将此依赖项添加到您的项目并重试。
