我们正在尝试使用 Spring data Jpa 将 Java 8 Spring boot 应用程序部署到 IBM WebSphere 8.5.5.21 服务器中。该应用程序在本地运行良好，但我们无法使其在 WebSphere 中运行。
这就是我在部署时遇到的错误。

我正在导出为 war 文件。
我做错了什么？
Spring Boot 2.7.7 依赖于 Java EE 8 技术。 WebSphere Application Server 8.5.5 支持 Java EE 6 技术。版本 9.0.5 支持 Java EE 7 技术。 Open 和 WebSphere Liberty 支持 Java EE 6 Web Profile、7、8 以及 Jakarta 8 和 9。因此 WebSphere Liberty（随 WebSphere Application Server 一起提供）是您应该部署 Spring Boot 2.7.7 应用程序的环境。
Spring Boot 2.7.9 或 2.7.7 至少需要 Servlet 5.0 规范和 Java 17。它与支持 Servlet 3.0 和 Java 7/8 的 WebSphere Liberty 8.5.5.21 不兼容。
要在 WebSphere Liberty 8.5.5.21 上部署 Spring Boot 应用程序，您需要使用与 Servlet 3.0 和 Java 7/8 兼容的早期版本的 Spring Boot。例如，您可以使用 Spring Boot 2.3.x 或 2.4.x.
需要注意的是，即使某个版本的 Spring Boot 与特定版本的 WebSphere Liberty 兼容，您的应用程序中使用的其他库或依赖项仍可能存在其他兼容性问题。在将应用程序部署到生产环境之前彻底测试它总是一个好主意。
确保 Javax-servlet-api 依赖看起来像这样
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>{Compatible Version}</version>
</dependency>
这里我没有使用 Scope provided ，因为如果你用“provided” scope 标记它，这意味着它将由服务器提供，而不是在应用程序打包时包含在 WAR 文件中。
您可以从 pom.xml 文件中的 javax.servlet-api 依赖项中删除“提供的”范围。这将确保在应用程序打包并部署到服务器时，依赖项包含在 WAR 文件中。
Spring Boot 2.6.x兼容Java 8，至少需要Servlet 4.0规范，WebSphere Liberty 8.5.5.21支持。
因此，您可以将 Spring Boot 2.6.3 与 Java 8 一起使用，并将您的应用程序部署到 WebSphere Liberty 8.5.5.21。
注意：这适用于 WebSphere Liberty - 8.5.5.21 不适用于 WebSphere 传统版本。
希望这对某些人有帮助。
