添加依赖

With Gradle, the dependency should be declared in the annotationProcessor configuration, as shown in the following example:

dependencies {
   //  kapt("org.springframework.boot:spring-boot-configuration-processor")   
    annotationProcessor ("org.springframework.boot:spring-boot-configuration-processor")
}

问题：因为我用的Kotlin，为什么kapt不行，一定要annotationProcessor
