该方法javax.servlet.ServletContext.getVirtualServerName()是在 servlet 版本中添加的3.1。因此，从您的堆栈跟踪我们可以推断出，出于某种原因，在您的情况下，gradle 正在为这个 jar 解析旧版本。这可能是因为您的 servlet 版本早于 3.1，或者其他一些 jar 的 servlet 版本早于 3.1，或者您的 tomcat 版本早于 8。因此，尝试将所有依赖项升级到可能的最新版本。就像'spring-jdbc'在您的项目中是版本“2.0.6”。也尝试将其升级到最新版本。

采取的步骤：

  • 重新检查所有依赖项以确保没有 jar 引用较旧的 servlet jar ，如果是，则将依赖项升级到最新版本。
  • 检查 gradle 依赖树。
  • 尝试添加到 gradle providedCompile 'javax.servlet:javax.servlet-api:3.1.0'，以便您的应用程序中使用的 servlet 版本与 tomcat 提供的版本相同。当您设置 gradle 提供的编译器目标时，它将使用提供的 jar 版本编译代码，但不会将其包含在 war/jar 中，因此最终部署时将使用 tomcat 提供的 servlet。但请确保您的 tomcat已更新并使用您在此处指定的相同版本的 servlet。

我能想到的最好方法是将所有相关依赖项更新到最新版本，以便 gradle 在编译时默认解析最新的 servlet 版本。
