Cannot resolve symbol 'SpringBootTest

该错误通常是由于缺少Spring Boot测试依赖项或测试类的不正确导入引起的。您可以尝试以下解决方法：

1. 确保您的项目中已经添加了Spring Boot测试依赖项，可以在pom.xml文件中添加以下依赖项：

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

2. 确保您的测试类已正确导入@SpringBootTest注释，可以在测试类的顶部添加以下导入语句：

        import org.springframework.boot.test.context.SpringBootTest;

通过以上两种方法可以解决Cannot resolve symbol 'SpringBootTest'，类引入不了的问题。

相关问题

Cannot resolve symbol SpringBootTest

主要原因是因为无法解析符号 "SpringBootTest"，可能的原因是没有正确导入相关的依赖包或者没有正确配置项目的环境。可以尝试以下方法解决该问题：

1. 检查项目的依赖配置，确保已经正确引入了Spring Boot Test相关的依赖包。可以确认是否在项目的pom.xml或者build.gradle文件中添加了正确的依赖项。

2. 确保项目的配置文件中已经正确配置了Spring Boot Test的相关注解。可以检查是否在测试类中正确导入了@SpringBootTest注解，并且确保该注解所在的包已经正确导入。

3. 如果使用的是IDE开发工具，可以尝试刷新项目或者重新构建项目，以确保所有依赖包正确加载。

4. 如果以上方法都无法解决问题，可以尝试重启开发工具或者清理并重新构建项目。

cannot resolve symbol SpringBootApplication

The "cannot resolve symbol SpringBootApplication" error typically occurs when the necessary dependencies for Spring Boot are not properly configured or missing in your project. To resolve this issue, you can follow these steps:

1. Make sure you have the correct dependencies in your project's pom.xml (for Maven) or build.gradle (for Gradle). Add the following dependency:

For Maven:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter</artifactId>
</dependency>

For Gradle:

implementation 'org.springframework.boot:spring-boot-starter'

2. Refresh your project dependencies by either rebuilding your project or using your IDE's refresh/reload dependencies feature.

3. If you are using an IDE like IntelliJ IDEA, try invalidating caches and restarting the IDE. This can help in resolving any caching issues.

4. Check if your IDE or build tool is correctly picking up the dependencies from the repository and that your internet connection is stable.

If you have followed these steps and still encounter the error, please provide more details about your project setup, such as the IDE, build tool, and any relevant code snippets.
