找不到符号：类 SpringExtension

Question

我正在尝试使用 SpringExtension 类来使用 JUnit5 进行测试类，语法如下：

@SpringBootTest @ExtendWith(SpringExtension.class)

但是，我在运行时遇到以下错误：

java: cannot find symbol   symbol: class SpringExtension

我的 POM 文件如下所示： ``

我缺少任何进口产品吗？

我希望能够将类作为依赖项导入，但这似乎不可能。请帮忙！

Answer 1

您遇到的错误表明在类路径中找不到 SpringExtension 类。此类由 spring-boot-starter-test 依赖项提供，您的 pom.xml 中缺少该依赖项。 添加依赖项后尝试重建项目。

<dependencies>
<!-- Other dependencies -->

<!-- Spring Boot Starter Test -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <version>3.3.0</version>
    <scope>test</scope>
</dependency>
