Spring boot 在SpringStarter项目中，值不会被提取到h2数据库中

spring-boot

Spring boot 在SpringStarter项目中，值不会被提取到h2数据库中,spring-boot,h2,Spring Boot,H2,我不熟悉Spring框架。在创建SpringStarter项目时，我选择了Web、JPA和H2数据库，然后创建了带有2个变量的Alien.Class，并创建了data.sql文件，通过使用该文件，我尝试将值提取到H2数据库中。但在添加data.sql文件后，我得到一个错误，显示无法执行sql脚本语句嵌套异常为未找到表“ALIEN”；SQL语句：插入外来值（101，'Vikram'）。请给出解决方案 1.外星人 package com.telusko.demo.model; import jav

H2试图将表名改为大写，并进行区分大小写的搜索，因此无法找到该表

尝试使用

；DATABASE_TO_UPPER=FALSE

属性并查看它是否工作

spring.datasource.url=jdbc:h2:mem:navin;DATABASE_TO_UPPER=FALSE

您可能想检查一下您使用的是哪个Spring启动版本？这是我的问题的解决方案--->默认情况下，data.sql脚本现在在初始化Hibernate之前运行。这使基于基本脚本的初始化行为与Flyway和Liquibase的行为保持一致。如果要使用data.sql填充Hibernate创建的架构，请将spring.jpa.defer-datasource-initialization设置为true。虽然不建议混合使用数据库初始化技术，但这也允许您在通过data.sql填充Hibernate创建的模式之前，使用schema.sql脚本来构建该模式。我已经按照您所说的做了，但出现了相同的控制台错误
