Spring Boot Koltin 项目中初始化 Hilla 时默认包错误

Question

我通过 Spring Initializer 创建了一个新的 Spring Boot + Hilla（Java 17、Kotlin、Gradle Kotlin）。打开项目并尝试运行 hillaAppInit 后，我得到：

Having the class annotated with @SpringBootApplication at the default package is not allowed by the Spring Boot as the component scan will fail during startup.

生成的主类看起来正确（例如，它确实有一个包）

package com.example.sample

import org.springframework.boot.autoconfigure.SpringBootApplication
import org.springframework.boot.runApplication

@SpringBootApplication
class SampleApplication

fun main(args: Array<String>) {
    runApplication<SampleApplication>(*args)
}
