如何使用Gradle Kotlin DSL导入Amazon S3进行春季启动

Question

我试图按照官方文档的说明在我的春季启动项目中导入S3，但依赖关系尚未解决。https://docs.aws.amazon.com/sdk-for-java/v2/developer-guide/setup-project-gradle.html

我将software.amazon.awssdk:bom从文档更新为最新的2.7.16，希望它可以解决。

这是我的build.gradle.kts文件

import org.jetbrains.kotlin.gradle.tasks.KotlinCompile
plugins {
    kotlin("plugin.jpa") version "1.3.31"
    id("org.springframework.boot") version "2.1.5.RELEASE"
    id("io.spring.dependency-management") version "1.0.7.RELEASE"
    kotlin("jvm") version "1.3.31"
    kotlin("plugin.spring") version "1.3.31"
    kotlin("plugin.noarg") version "1.3.31"
}
allOpen {
    annotation("javax.persistence.Entity")
    annotation("javax.persistence.MappedSuperclass")
    annotation("javax.persistence.Embeddable")
}
noArg {
    annotation("javax.persistence.Entity")
}
group = "com.leaveentry"
version = "0.0.1-SNAPSHOT"
java.sourceCompatibility = JavaVersion.VERSION_1_8
repositories {
    mavenCentral()
}
dependencies {
    implementation("org.springframework.boot:spring-boot-starter-data-jpa")
    implementation("org.springframework.boot:spring-boot-starter-security")
    implementation("org.springframework.boot:spring-boot-starter-web")
    implementation("com.fasterxml.jackson.module:jackson-module-kotlin")
    implementation("org.jetbrains.kotlin:kotlin-reflect")
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
    implementation("com.google.api-client:google-api-client:1.25.0")
    implementation("io.jsonwebtoken:jjwt-api:0.10.5")
    implementation(platform("software.amazon.awssdk:bom:2.7.16"))
    implementation("software.amazon.awssdk:s3")
    runtimeOnly("com.h2database:h2")
    runtimeOnly("mysql:mysql-connector-java")
    runtimeOnly("io.jsonwebtoken:jjwt-impl:0.10.5")
    runtimeOnly("io.jsonwebtoken:jjwt-jackson:0.10.5")
    annotationProcessor("org.springframework.boot:spring-boot-configuration-processor")
    testImplementation("org.springframework.boot:spring-boot-starter-test")
    testImplementation("org.springframework.security:spring-security-test")
}
tasks.withType<KotlinCompile> {
    kotlinOptions {
        freeCompilerArgs = listOf("-Xjsr305=strict")
        jvmTarget = "1.8"
    }
}

当我尝试导入S3相关类时，它们无法解决。

import com.amazonaws.auth.AWSStaticCredentialsProvider
import com.amazonaws.auth.BasicAWSCredentials
import com.amazonaws.regions.Regions
import com.amazonaws.services.s3.AmazonS3ClientBuilder
import com.amazonaws.services.s3.model.CannedAccessControlList
import com.amazonaws.services.s3.model.PutObjectRequest

我也有类似的问题，尽管我没有设法使亚马逊的特定版本工作，但我找到了解决方法。

添加到您的build.gradle.kts以下行：

dependencyManagement {
    imports {
        mavenBom("com.amazonaws:aws-java-sdk-bom:1.11.228")
    }
}

以及dependencies块中的以下实现：

implementation("software.amazon.awssdk:s3:2.10.1")

注意：另外，如果要一次包含所有服务，则可以添加以下内容：

implementation("software.amazon.awssdk:aws-sdk-java:2.10.1")
