JDBC Testing Support

JdbcTestUtils

org.springframework.test.jdbc 包包含 JdbcTestUtils，它是一系列JDBC 相关实用功能，旨在简化标准数据库测试场景。具体来说，JdbcTestUtils 提供以下静态实用方法。

The org.springframework.test.jdbc package contains JdbcTestUtils, which is a collection of JDBC-related utility functions intended to simplify standard database testing scenarios. Specifically, JdbcTestUtils provides the following static utility methods.

  • countRowsInTable(..): Counts the number of rows in the given table.

  • countRowsInTableWhere(..): Counts the number of rows in the given table by using the provided WHERE clause.

  • deleteFromTables(..): Deletes all rows from the specified tables.

  • deleteFromTableWhere(..): Deletes rows from the given table by using the provided WHERE clause.

  • dropTables(..): Drops the specified tables.

AbstractTransactionalJUnit4SpringContextTests和AbstractTransactionalTestNGSpringContextTests提供一些便利方法，这些方法委托给`JdbcTestUtils`中的上述方法。

AbstractTransactionalJUnit4SpringContextTests and AbstractTransactionalTestNGSpringContextTests provide convenience methods that delegate to the aforementioned methods in JdbcTestUtils.

Embedded Databases

`spring-jdbc`模块为配置和启动嵌入式数据库提供支持，你可以在与数据库交互的集成测试中使用它。有关详情，请参阅Embedded Database Support和Testing Data Access Logic with an Embedded Database。

The spring-jdbc module provides support for configuring and launching an embedded database, which you can use in integration tests that interact with a database. For details, see Embedded Database Support and Testing Data Access Logic with an Embedded Database.
