Question

某些背景信息：

我正在使用spring批处理POC来替换数据提取和报告框架。我们从Oracle数据库中读取数据并从那里生成CSV报告。现在我有这个工作和单元测试连接到oracle db。但是，我更愿意删除Oracle db的外部依赖关系来测试。

问题：

当需要向db添加数据时，dbunit抱怨表'Account'不存在。

日志记录：

我可以看到要删除的sql并创建被触发的表：

06:54:58,940 DEBUG org.springframework.jdbc.core.JdbcTemplate:417 - Executing SQL statement [DROP TABLE ACCOUNT CASCADE CONSTRAINTS]
06:54:58,988 DEBUG org.springframework.jdbc.core.JdbcTemplate:417 - Executing SQL statement [CREATE TABLE ACCOUNT ( ID NUMBER(22) NOT NULL, CURRENT_BALANCE NUMBER(22) NOT NULL, RESERVED_AMOUNT NUMBER(22), ACCOUNT_TYPE VARCHAR2(50) NOT NULL, CURRENCY_CODE CHAR(3) NOT NULL, ACCOUNT_STATUS VARCHAR2(50) NOT NULL, PRODUCT_ID NUMBER(22) DEFAULT 0, CLIENT_CODE VARCHAR2(50) NOT NULL, LEDGER_ACCOUNT_TYPE VARCHAR2(50), CHANGED_BY VARCHAR2(50) NOT NULL, CHANGED_ON TIMESTAMP(6) NOT NULL, VERSION INTEGER DEFAULT 0, ACTIVATION_DATE TIMESTAMP(6), NEXT_BILLING_DATE TIMESTAMP(6), MSISDN VARCHAR2(50), IS_DEFAULT CHAR(1) DEFAULT '0', CONSTRAINT PK_ACCOUNT PRIMARY KEY (ID) )]

我有一个SQL脚本来为dbunit创建db模式和flat xml数据以进行填充。从日志记录中我可以看到以下情况：

Dbunit加载xml数据：

drop / create代码使用与db unit部分相同的数据源，因此我认为它不会在mem h2实例中创建一个新的。

有什么想法吗？

Answer 1

我也遇到过这个。当dbunit尝试删除表时，它找不到它，因此也就是问题。我通过在删除DDL中添加“IF EXISTS”来修复它。

希望有所帮助。

通过dbunit使用设置数据重新创建h2 db
