maven - 运行 Junit 测试用例时 H2 数据库异常 "Caused by: org.h2.jdbc.JdbcSQLException: Sequence "SYSTEM_SEQUENCE_ *"not found;"

标签 maven junit h2 spring-tool-suite

我在执行 junit 测试用例时遇到错误，提示 Caused by: org.h2.jdbc.JdbcSQLException: Sequence "SYSTEM_SEQUENCE_BBAED672_9E78_4AC7_9306_10A675C3C8D2"not found; SQL语句

我正在处理一个项目 Project_Animal，我在其中使用实体类“EntityAnimals”。 我在同一工作区中有另一个项目 Project_Fruit，我在其中使用实体类“EntityFruits”。

在运行 Project_Animal 测试用例时，EntityFruits 出现以下(日志)错误。

我尝试创建一个新工作区并重新安装 STS。但它没有用。

我的查询
1. h2-db中的CACHED是什么意思 -> CREATE CACHED TABLE CAP.EntityFruits
2.为什么只在我的机器上发生，同样的测试用例在其他机器上成功通过

以下是堆栈跟踪 -

这是我的yaml文件

spring:
  application:
    name: ws_animals
  jpa:
    hibernate:
      ddl-auto: create
      naming:
       physical-strategy: org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
    database: SQL_SERVER
    show-sql: true
    properties:
      hibernate:
        dialect: org.hibernate.dialect.SQLServer2012Dialect
        id:
          new_generator_mappings: false
datasource:
    maxTotal: 10
    maxActive: 10
    initial-size: 1
    test-on-borrow: false
    test-while-idle: true
    time-between-eviction-runs-millis: 60000
    driver-class-name: org.h2.Driver
    validation-query: SELECT 1
    url: jdbc:h2:~/account;DB_CLOSE_ON_EXIT=TRUE;INIT=RUNSCRIPT FROM 'classpath:init.sql'

最佳答案

终于找到了解决办法。

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

因此它将 h2Database 的缓存数据 存储在account.db、account.mv 等中.(扩展名为 .db 的文件)我的用户目录中的文件(~)。

这些文件在执行 Fruit_Project 测试用例时损坏。

由于两个项目的数据源 url 相同，它影响了我的其他项目。因此，改变工作空间没有帮助。

解决方案——
1. 我删除这些文件，砰的一声，所有的 junit 测试用例都开始执行了。
或者
2.更改数据源url -> url: jdbc:h2:~/some_other_name;

关于maven - 运行 Junit 测试用例时 H2 数据库异常 "Caused by: org.h2.jdbc.JdbcSQLException: Sequence "SYSTEM_SEQUENCE_ *"not found;"，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/51492125/
