java.lang.IllegalArgumentException : Cannot instantiate interface org. springframework.context.ApplicationContextInitializer

Question

我尝试在安装 Spring CLI 后运行快速启动 cli 示例。

https://docs.spring.io/spring-boot/docs/current/reference/html/getting-started-installing-spring-boot.html#getting-started-cli-example

开启:$ spring run app.groovy

错误:

请大家指导一下。

我不确定你是否可以尝试一下:

--add-modules=java.sql

我假设 spring.boot 是一个自动模块。自动模块不会声明它的依赖项，因此您必须使用 --add-modules 来确保解析所需的任何显式模块。如果 spring.boot 是一个显式模块，那么我假设它需要 java.sql 并且您不会遇到此问题。
