在YouTube上跟随了Spring + Kotlin = Modern + Reactive + Productive个演示文稿！通过使用https://start.spring.io/..创建一个基于Kotlin的Spring Web Fluxreact 性应用程序.
使用这些依赖项生成了项目(请注意Spring Boot和Java版本):
这将生成build.gradle.kts个文件:
plugins {
java
id("org.springframework.boot") version "3.0.6"
id("io.spring.dependency-management") version "1.1.0"
id("org.graalvm.buildtools.native") version "0.9.20"
}
group = "bootiful"
version = "0.0.1-SNAPSHOT"
java.sourceCompatibility = JavaVersion.VERSION_17
repositories {
mavenCentral()
}
extra["testcontainersVersion"] = "1.18.1"
dependencies {
implementation("org.springframework.boot:spring-boot-starter-data-r2dbc")
implementation("org.springframework.boot:spring-boot-starter-webflux")
runtimeOnly("org.postgresql:postgresql")
runtimeOnly("org.postgresql:r2dbc-postgresql")
testImplementation("org.springframework.boot:spring-boot-starter-test")
testImplementation("io.projectreactor:reactor-test")
testImplementation("org.testcontainers:junit-jupiter")
testImplementation("org.testcontainers:postgresql")
testImplementation("org.testcontainers:r2dbc")
}
dependencyManagement {
imports {
mavenBom("org.testcontainers:testcontainers-bom:${property("testcontainersVersion")}")
}
}
tasks.withType<Test> {
useJUnitPlatform()
}
当我最初try 在MacOS上使用gradle build&；./gradlew build(两者都使用IntelliJ&；命令行)构建它时(在下载和解压压缩文件之后)，遇到错误.
当我克隆本演示文稿所基于的GitHub project时，我收到了同样的错误:
使用gradle build(使用包装器时也失败，例如./gradlew build):

为什么当我从存储库中创建一个新的git clone%时，我不能构建这个？
这是我正在try 构建的项目:
https://github.com/jamesward/nks/tree/main/bootiful个
Docker守护进程正在运行，我运行了以下命令(在try 使用gradle build和/或./gradlew build构建之前)
docker ps:
输出:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
就像，我说过，当我从http://start.spring.io以内创建一个新项目时，也发生了这种情况.这是由于TestContainers造成的吗？设置TestContainers或任何其他配置是否需要任何步骤/前提条件？
运行位于以下位置的Unixshell 脚本后:
https://github.com/jamesward/nks/blob/main/postgres.sh个
然后判断停靠器守护进程:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
d12e7449a853 postgres:13.3 "docker-entrypoint.s…" 36 seconds ago Up 33 seconds 0.0.0.0:5432->5432/tcp my-postgres
Unixshell 脚本的尾部:

当我向内看时:../build/reports/tests/test/index.html:
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'r2dbcScriptDatabaseInitializer' defined in class path resource [org/springframework/boot/autoconfigure/sql/init/R2dbcInitializationConfiguration.class]: Failed to execute database script

如果其他人能try 复制这一问题，我将不胜感激.
记住，当我通过http://start.spring.io创建一个项目时，使用YouTube演示视频中的演示者使用的相同依赖关系(见上面的屏幕截图)，这不起作用；当我通过新的git clone创建项目时，作者的code也不起作用.
