面对'NoClassDefFoundError：org / springframework / data / repository / config / BootstrapMode'问题，运行测试时

Question

这些是在我的pom.xml文件中添加的与春季相关的jars

<dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-jpa</artifactId>
        <version>2.2.0.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-commons</artifactId>
        <version>2.0.5.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
        <version>2.2.0.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <version>2.2.0.RELEASE</version>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-logging</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

我看到的错误是：

我尝试通过在pom.xml中更改不同版本的spring / jpa等来尝试，但是问题仍然存在。

Answer 1

您的spring-data-commons版本太旧，并且该版本没有BootstrapMode类。对于其他spring依赖项，请尝试将其升级到2.2.0.RELEASE。
