java - 运行测试时无法使用 spring-boot-starter-web 依赖项

Question

我有使用 gradle(web,common,batch) 的多模块项目

项目运行良好

但是，当我尝试从批处理模块的测试文件夹中运行 junit 时，当 Spring 出现时，我得到了这个:

Caused by: java.lang.NoClassDefFoundError: org/springframework/http/converter/xml/MappingJackson2XmlHttpMessageConverter

我从批处理模块检查了依赖关系树:

<batch>gradle -q dependencies --configuration testRuntime

我在尝试导入 spring-boot-start-web 时看到按钮失败

这是我在批处理模块上的 build.gradle:

buildscript {
    repositories {
        maven { url "http://repo.spring.io/libs-release" }
        mavenLocal()
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:$project.ext.springBootVersion")

    }
}

description = 'batch'

dependencies {
    compile("org.springframework.boot:spring-boot-starter-batch:$project.ext.springBootVersion")
    testRuntime("org.springframework.batch:spring-batch-test:$project.ext.springBatchVersion") {
        exclude(module: 'spring-test')
        exclude(module: 'spring-jdbc')
        exclude(module: 'commons-io')
        exclude(module: 'commons-collections')
    }

    /* compile ('org.springframework.integration:spring-integration-core:4.1.2.RELEASE')*/
    compile project(":common")
    testRuntime("org.springframework.boot:spring-boot-starter-web")

}

知道出了什么问题吗？

谢谢。

您要么需要在声明依赖项时提供版本号，要么需要应用 Spring Boot 插件(您已将该插件声明为构建脚本依赖项，但似乎并未应用它) .

当应用 Spring Boot 插件时，它会自动将 spring-boot-starter-web 的版本设置为与插件相同的版本。你可以看到一个list of all the versions该插件可以在文档中为您设置。
