spring-boot - Spring Boot 2.0.4 - H2 数据库 - @SpringBootTest - 因 : org. h2.jdbc.JdbcSQLException 导致失败:未找到架构 "classpath:db/schema.sql"

Question

我使用 Spring Boot 2.0.4 构建了一个应用程序并与 JPA 集成。

现在我想使用 h2 数据库运行一些测试，但无法使用 h2 执行 Spring Boot 测试。

异常(exception)情况如下所示:

我的 application-test.properties 是:

spring.datasource.driver-class-name=org.h2.Driver
spring.datasource.jdbc-url=jdbc:h2:mem:test
spring.datasource.schema=classpath:db/schema.sql
spring.datasource.data=classpath:db/data.sql
spring.datasource.initialization-mode=always


spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=none
logging.level.org.hibernate.SQL=debug
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect

这些异常发生在我执行 schema.sql 时，但 h2 希望在 spring.datasource.schema 中指定的名为“classpath:schema.sql”的模式中执行此脚本。

Answer 1

通过 Not Found 异常可以清楚地看出 Spring boot 无法找到 schema.sql 文件。

只需将src/main/resources/db/schema.sql复制到src/test/resources/db/schema.sql即可。
