Maven H2数据库异常“；原因：org.h2.jdbc.jdbcsql异常：序列“；系统“U序列”；未找到&引用；在运行Junit测试用例时

maven junit

Maven H2数据库异常“；原因：org.h2.jdbc.jdbcsql异常：序列“；系统“U序列”；未找到&引用；在运行Junit测试用例时,maven,junit,h2,spring-tool-suite,Maven,Junit,H2,Spring Tool Suite,我在执行junit测试用例时遇到一个错误，原因是：org.h2.jdbc.JdbcSQLException:Sequence“SYSTEM_Sequence_BBAED672_9E78_4AC7_9306_10A675C3C8D2”未找到；SQL语句 我正在处理一个项目project\u Animal，其中我使用实体类“EntityAnimals”。 在同一个工作区中，我有另一个项目project\u Fruit，我正在使用实体类“EntityFruits” 运行Project\u Animal

我在执行junit测试用例时遇到一个错误，原因是：org.h2.jdbc.JdbcSQLException:Sequence“SYSTEM_Sequence_BBAED672_9E78_4AC7_9306_10A675C3C8D2”未找到；SQL语句

我正在处理一个项目
project\u Animal
，其中我使用实体类“
EntityAnimals
”。 在同一个工作区中，我有另一个项目
project\u Fruit
，我正在使用实体类“
EntityFruits
”

运行
Project\u Animal
测试用例时，我发现
EntityFruits
的以下（日志）错误

我尝试创建一个新的工作区，并重新安装STS。但它不起作用

我的疑问
1.h2 db->
创建缓存表CAP.EntityFruits

2.为什么只有在我的机器上才会发生这种情况，相同的测试用例在其他机器上成功通过

以下是stacktrace-

最后我找到了解决办法

在我的YML文件中，我的数据源url为
url:jdbc:h2:~/account

因此，它将H2数据库的缓存数据存储在
account.db、account.mv
等（扩展名为
.db
的文件）我的用户目录（
~
）中

这些文件在执行
Fruit\u项目
测试用例时损坏

由于这两个项目的数据源url相同，因此会影响我的另一个项目。因此，更改工作区并没有帮助

解决方案-

1.I删除了这些文件，所有junit测试用例开始执行

或


2.更改数据源url->
url:jdbc:h2:~/some\u other\u name
您在构建时使用的工具是什么？可以添加构建文件（pom.xml或build.gradle）吗？我正在使用maven进行构建，原因是：java.sql.SQLException:无法创建PoolableConnectionFactory（序列“SYSTEM_Sequence_BBAED672_9E78_4AC7_9306_10A675C3C8D2”找不到；您在数据库中定义了这个序列吗？请检查更新的帖子。@AnilBachola如何在H2数据库中找到序列？谢谢，我有类似的问题，删除
.db
文件很有帮助！
