Reactive Spring Boot - java.lang.NoSuchFieldError: DEFAULT_SHUTDOWN_QUIET_PERIOD
Reactive Spring Boot - java.lang.NoSuchFieldError: DEFAULT_SHUTDOWN_QUIET_PERIOD
我正在尝试将旧的 spring 应用程序迁移到 springboot 2.3.1 和 spring 5.2.7。目标是制作一个反应式应用程序。但是我被困在下面。我不完全确定我还需要升级什么。
这是我的 pom 的一部分，其他库是内部库，不过我认为不会有任何冲突。

看起来您缺少 reactor-netty-0.9.8.RELEASE.jar，它具有常量 DEFAULT_SHUTDOWN_QUIET_PERIOD 在它的 LoopResources 接口中定义。
我在您的 POM 中注意到的最重要的事情是您同时拥有 spring-webmvc 和 spring- boot-starter-webflux 作为依赖。
如 Spring 引导参考文档中所述，如果 MVC 和 WebFlux 都可用，Spring 引导将自动配置 Spring MVC 应用程序，因为 Spring MVC 无法在 Netty 服务器上 运行。
这就是为什么 不要将 Web 依赖项与 webflux 混在一起。如果您正在尝试构建反应式微服务，只需使用 spring-boot-starter-webflux 并删除 web、webmvc 和所有。
另外正如@thomas 提到的，没有必要单独包含 spring-core，因为它带有所有 spring 引导启动器依赖项。要查看发生的情况，请使用 mvn dependency:tree 或 ./gradlew :dependencies 并检查依赖关系树。
