Springboot项目的测试类报错了，怎么解决？

Answer 1

【以下回答由 GPT 生成】

这个问题是由于在进行单元测试时，Spring没有找到默认的配置类引起的。解决这个问题的方法是在单元测试类上添加@SpringBootTest(classes = YourSpringBootApp.class)注解，并将YourSpringBootApp.class替换为你的应用程序主类。

假设你的应用程序主类是SpringbootMybatisApplication，你可以按照以下步骤进行修改：

1. 在单元测试类上添加@SpringBootTest(classes = SpringbootMybatisApplication.class)注解。这将告诉Spring在执行单元测试时使用主类作为配置类。

@SpringBootTest(classes = SpringbootMybatisApplication.class)
public class SpringbootMybatisApplicationTest {
    // your test cases
}

1. 运行你的单元测试。现在，你应该可以成功运行测试而不再遇到错误信息。

这样做的原因是@SpringBootTest(classes = YourSpringBootApp.class)注解告诉Spring在加载单元测试时使用指定的启动类作为配置类。这样，Spring就可以找到正确的配置并正确加载应用程序上下文，从而解决错误。

希望这个解决方案能帮到你。如果你还有其他问题，请随时提问。
