spring-boot - 启动后立即关闭意外的 Web 应用程序

Question

这些是我的 Web 应用程序中包含的当前依赖项。

dependencies {
    implementation("org.springframework.boot:spring-boot-starter-data-jpa")
    implementation("org.springframework.boot:spring-boot-starter-data-rest")
    implementation("org.springframework.boot:spring-boot-starter-web")
    implementation("org.springframework.boot:spring-boot-starter-web-services")
    implementation("com.fasterxml.jackson.module:jackson-module-kotlin")
    implementation("org.jetbrains.kotlin:kotlin-reflect")
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
    implementation("com.google.firebase:firebase-admin:6.10.0")
}

每次运行应用程序时，都会出现以下错误：

如何避免应用程序关闭？

编辑：以下是我的 SpringBoot 注释类

package unito.taas.project

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

@SpringBootApplication
class ProjectApplication

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