我使用Spring Boot和Postgres用Java编写了一些后端应用程序。
如果我从Intelliji本地运行，应用程序可以完美地工作，但是当我编译到jar并运行docker build --no-cache -t application.jar .和docker-compose up时，后端崩溃了。postgres容器似乎工作正常，但是spring引导容器失败，出现以下问题:

如果有聪明的人能解释一下为什么会发生这种情况，那就太好了，因为我已经被这个问题困了多久了。
我的JAR所依赖的注释处理器之一，即
annotationProcessor group: 'org.springframework.boot', name: 'spring-boot-configuration-processor', version: '2.5.3'
由于缺少实现语句，没有到达JAR。
我通过添加
修复了它implementation 'org.springframework.boot:spring-boot-configuration-processor:2.5.3';
作为bootJargradle任务的依赖项。
