java - 无法在spring boot中使用内存数据库

转载作者：行者123 更新时间：2023-11-29 08:40:19

我正在关注一本书Spring REST，它被引用为

Spring Boot provides excellent support for HSQLDB-, H2-, and Derby-embedded databases. The only requirement is to include a build dependency in the pom.xml file. Spring Boot takes care of starting the database during deployment and stopping it during application shutdown. There is no need to provide any database connection URLs or username and password.

<dependency>
<groupId>org.hsqldb</groupId>
<artifactId>hsqldb</artifactId>
<scope>runtime</scope>
</dependency>

mvc clean-verify

现在，当我在没有这个内存的情况下运行我的应用程序时，一切正常，但是当我涉及这个时，出现异常

我在使用 JPA 注释 时是否遗漏了一些东西，例如 @entity 和所有基础知识。

请帮忙

测试类 我没有自定义测试，只有一个默认

@RunWith(SpringRunner.class)
@SpringBootTest
public class QuickPollApplicationTests {

    @Test
    public void contextLoads() {
    }

}

最佳答案

确保您的 JPA 配置正确。然后尝试使用 @DataJpaTest 注释而不是 @SpringBootTest。它配置一个内存数据库。

如果你想使用@SpringBootTest，你需要使用@ContextConfiguration提供你自己的配置。
