未解决的参考：使用@ExtendWith注释的SpringExtension
我正在使用SpringBoot中的Junit 5来利用它提供的一些新function。 基本的设置工作，我可以使用新的注释，如@BeforeAll和@AfterAll但是，我相信，因为我不能解决@ExtendWith(SpringExtension::class)我不能初始化我的测试类，以使用注入资源。 我已经尝试将所需的依赖项添加到我的build.gradle文件，但我假设我缺少一个键依赖项：
buildscript { ext.dokka_version = '0.9.15' ext.dockerVersion = '1.2' ext.junit4Version = '4.12' ext.junitVintageVersion = '4.12.2' ext.junitPlatformVersion = '1.0.2' ext.junitJupiterVersion = '5.0.2' ext.kotlin_version = '1.1.60' ext.log4jVersion = '2.9.0' ext.springVersion = '1.5.8.RELEASE' repositories { mavenCentral() jcenter() } dependencies { // Needed for the 'kotlin' plugin classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:${kotlin_version}") // Needed for the 'org.springframework.boot' plugin classpath("org.springframework.boot:spring-boot-gradle-plugin:${springVersion}") // Needed for the 'kotlin-spring' plugin classpath("org.jetbrains.kotlin:kotlin-allopen:${kotlin_version}") //Needed for 'docker' plugin classpath("se.transmode.gradle:gradle-docker:${dockerVersion}") //Needed for 'dokka' plugin classpath("org.jetbrains.dokka:dokka-gradle-plugin:${dokka_version}") // Needed for Junit 5 classpath("org.junit.platform:junit-platform-gradle-plugin:${junitPlatformVersion}") } } // Allows us to compile Kotlin files apply plugin: 'kotlin' // Does some extra work to set up Spring Boot. // Specifically this gives us the "bootRun" task we will be using apply plugin: 'org.springframework.boot' // Allows for improved interoperability between Kotlin and Spring apply plugin: 'kotlin-spring' // Allows us to create docker image apply plugin: 'docker' //Allows us to create API documentation apply plugin: 'org.jetbrains.dokka' apply plugin: 'idea' apply plugin: 'java' apply plugin: 'org.junit.platform.gradle.plugin' junitPlatform { // platformVersion '1.0.2' filters { engines { // include 'junit-jupiter', 'junit-vintage' // exclude 'custom-engine' } tags { // include 'fast' exclude 'slow' } // includeClassNamePattern '.*Test' } // enableStandardTestTask true // reportsDir file('build/test-results/junit-platform') // this is the default //logManager 'org.apache.logging.log4j.jul.LogManager' } task buildDocker(type: Docker, dependsOn: [build, dokka]) { applicationName = jar.baseName dockerfile = file('Dockerfile') doFirst { copy { from jar into stageDir } } } dokka { outputFormat = 'html' outputDirectory = $buildDir / doc } repositories { mavenCentral() } compileJava { sourceCompatibility = 1.8 targetCompatibility = 1.8 } compileTestJava { sourceCompatibility = 1.8 targetCompatibility = 1.8 options.compilerArgs += '-parameters' } dependencies { // JPA and H2 compile("org.springframework.boot:spring-boot-starter-data-jpa") compile("com.h2database:h2") compile "org.hibernate:hibernate-entitymanager:5.2.10.Final" compile "org.hibernate:hibernate-core:5.2.10.Final" compile "org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlin_version" compile "org.slf4j:slf4j-api:1.7.25" // Kotlin Dependencies compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version" compile "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version" testCompile "org.jetbrains.kotlin:kotlin-test-junit:$kotlin_version" testCompile "org.springframework.boot:spring-boot-starter-test" //testCompile "org.springframework.boot:spring-boot-starter-test" { // exclude(module = "junit") //} // Mockito //testCompile "org.mockito:mockito-core:2.11.0" //testCompile "com.nhaarman:mockito-kotlin-kt1.1:1.5.0" //AssertJ testCompile 'org.assertj:assertj-core:3.8.0' // JUnit Jupiter API and TestEngine implementation testCompile("org.junit.jupiter:junit-jupiter-api:${junitJupiterVersion}") testCompile("org.junit.platform:juint-platform-runner:${junitPlatformVersion}") testRuntime("org.junit.jupiter:junit-jupiter-engine:${junitJupiterVersion}") // Only needed to run tests in an (IntelliJ) IDE(A) that bundles an older version testRuntime("org.junit.platform:junit-platform-launcher:${junitPlatformVersion}") // If you also want to support JUnit 3 and JUnit 4 tests //testCompile ("junit:junit:${junit4Version}") //testRuntime ("org.junit.vintage:junit-vintage-engine:${junitVintageVersion}") // To avoid compiler warnings about @API annotations in JUnit code testCompileOnly("org.apiguardian:apiguardian-api:1.0.0") // Spring Dependencies compile("org.springframework.boot:spring-boot-starter-web") { exclude module: "spring-boot-starter-tomcat" } compile "org.springframework.boot:spring-boot-starter-jetty" compile "org.springframework.boot:spring-boot-starter-actuator" // Jackson Dependencies compile "com.fasterxml.jackson.core:jackson-annotations" compile "com.fasterxml.jackson.core:jackson-core" compile "com.fasterxml.jackson.core:jackson-databind" runtime "com.fasterxml.jackson.datatype:jackson-datatype-jdk8" runtime "com.fasterxml.jackson.datatype:jackson-datatype-jsr310" runtime "com.fasterxml.jackson.module:jackson-module-kotlin" } configurations.all { exclude group: "org.slf4j", module: "slf4j-log4j12" exclude group: "log4j", module: "log4j" } task wrapper(type: Wrapper) { gradleVersion = "4.3" }
我没有看到在spring-test-junit5任何地方声明的spring-test-junit5依赖。 根据JUnit 5 Spring扩展的文档 ：
如果您想为spring-test-junit5构建发布标签，那么您可能对使用JitPack感兴趣。 例如，要针对1.0.2标记构建，以下Maven坐标将起作用。
Group ID: com.github.sbrannen Artifact ID: spring-test-junit5 Version: 1.0.2
与Gradle的JitPack
repositories { mavenCentral() maven { url 'https://jitpack.io' } } // ... dependencies { // ... testCompile('com.github.sbrannen:spring-test-junit5:1.0.2') // ... }
更新：
从以下注释中提取（由JUnit5 Spring Extension的作者提供）：
如果您使用Spring Framework 5.x中的spring-test，则不需要spring-test-junit5构件（仅适用于Spring Framework 4.3.x）
我错过了以下依赖项：
dependencies { compile 'org.springframework:spring-context:5.0.1.RELEASE' }
最终，由于我的build.gradle，有很多依赖项不匹配。 确保所有的spring模块都是从5.0.1.RELEASE中派生出来的，我从之前的版本中发现了一些导致不同错误的东西。 我最终定义了我的版本：
ext { antJunitVersion = '1.9.7' assertjcoreVersion = '3.8.0' apiguardianVersion = '1.0.0' dokkaVersion = '0.9.15' dockerVersion = '1.2' h2Version = '1.4.196' hibernateVersion = '5.2.12.Final' jacksonVersion = '2.9.1' junit4Version = '4.12' junitVintageVersion = '4.12.2' junitPlatformVersion = '1.0.2' junitJupiterVersion = '5.0.2' kotlinVersion = '1.1.60' log4jVersion = '2.9.1' springVersion = '5.0.1.RELEASE' springBootVersion = '1.5.8.RELEASE' slf4jVersion = '1.7.25' }
然后将它们声明为明确的依赖关系
// Spring Dependencies compile("org.springframework:spring-webmvc:${springVersion}") compile("org.springframework:spring-web:${springVersion}") compile("org.springframework:spring-aspects:${springVersion}") compile("org.springframework:spring-aop:${springVersion}") compile("org.springframework:spring-orm:${springVersion}") compile("org.springframework:spring-jdbc:${springVersion}") compile("org.springframework:spring-tx:${springVersion}") compile("org.springframework:spring-beans:${springVersion}") compile("org.springframework:spring-expression:${springVersion}") compile("org.springframework:spring-core:${springVersion}") compile("org.springframework:spring-context:${springVersion}") compile("org.springframework:spring-test:${springVersion}") compile("org.springframework.boot:spring-boot-starter-web:${springBootVersion}") { exclude module: "spring-boot-starter-tomcat" } compile "org.springframework.boot:spring-boot-starter-jetty:${springBootVersion}" compile "org.springframework.boot:spring-boot-starter-actuator:${springBootVersion}"
