目前我有一个 spring boot 应用程序，它使用 wiremock 来模拟集成测试中的外部服务依赖项。然而，我经历过这些测试非常脆弱且不可预测，并且需要花费大量时间来执行。
我想知道在 Spring Boot 应用程序中是否有更好的方法来模拟外部服务依赖以进行集成测试？
我通过为web,安全性,验证和spring-boot cassandra选择了一些依赖项来下载spring initializer项目.当我尝试运行./gradlew bootrun时,我在启动期间遇到以下异常

我是 Intellij 的新手，正在从 Eclipse 迁移过来。我有一个关于显示 java 源文件大纲的键盘快捷键的问题。在 Eclipse 中，我们使用 Ctrl+O 来基本上显示类的轮廓。但是我无法找出在 Intellij 中执行相同操作的快捷方式。
根据 Intellij 文档，它说我们需要按 Cmd+F12（我也转移到 Mac），但这永远不会调用代码大纲。请帮忙。
