java - org.springframework.beans.factory.BeanCreationException : Error creating bean with name 'scriptDataSourceInitializer' defined in class path resources?

Question

我是学习 spring boot web 的新手。我已经开始学习使用 h2 数据库的 spring jpa 数据。我想使用

在其中插入测试数据

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scriptDataSourceInitializer' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceInitializationConfiguration$SharedCredentialsDataSourceInitializationConfiguration.class]: Invocation of init method failed; nested exception is org.springframework.jdbc.datasource.init.ScriptStatementFailedException: Failed to execute SQL script statement #1 of URL [file:/E:/Programing/Java/boot/SpringBootJpa/target/classes/data.sql]: insert into alien values(101,'Rahul','Java'); nested exception is org.h2.jdbc.JdbcSQLSyntaxErrorException: Table "ALIEN" not found; SQL statement:

    }

我还检查了堆栈跟踪，其中显示未找到外星人表。但是当我早些时候检查 h2 控制台时，它显示外星人表存在。

你能帮帮我吗？

Answer 1

您必须设置为告诉 Spring Boot 首先完成 Hibernate DDL 生成，然后执行 SQL 文件。

spring.jpa.defer-datasource-initialization=true

请阅读: https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto.data-initialization.using-basic-sql-scripts
