从错误日志来看,问题出在加载derby-schema.sql文件时出现了错误。这可能是由于以下原因导致的:
数据库连接配置不正确。请检查您的数据库连接配置,确保数据库地址、端口、用户名和密码等信息正确无误。
derby-schema.sql文件不存在或路径不正确。请确保该文件存在于正确的路径下,并且Spring Boot应用程序可以访问到它。
数据库驱动缺失或版本不兼容。请确保您的项目中包含了正确的数据库驱动,并且版本与数据库兼容。
数据库服务未启动或无法访问。请检查数据库服务是否已启动,以及您的应用程序是否可以访问到数据库服务。
您可以尝试以下解决方案:
检查并更新数据库连接配置。
确保derby-schema.sql文件存在于正确的路径下,并且Spring Boot应用程序可以访问到它。
添加正确的数据库驱动依赖到您的项目中。例如,如果您使用的是MySQL数据库,可以在pom.xml文件中添加以下依赖:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.26</version>
</dependency>
