我尝试使用其他执行侦听器（我在 DbUnit documentation 中找到），但我遇到了同样的异常...
@TestExecutionListeners({
DependencyInjectionTestExecutionListener.class,
DirtiesContextTestExecutionListener.class,
TransactionDbUnitTestExecutionListener.class
})
更新：我试图添加一个明确的拆解：在 testCase() 方法的末尾删除了 Book。但是异常仍然存在。
它在你的堆栈跟踪中说：
org.h2.jdbc.JdbcSQLException: Referential integrity constraint violation: "FK_JNCMPQJWFCJEXX62EA1P06VLP: ITEST.BOOK FOREIGN KEY(LIBRARY_ID) REFERENCES ITEST.ORGANIZATION(ID) (2)"; SQL statement:delete from ORGANIZATION [23503-195]
因此当 BOOK table 中仍有记录引用 ORGANIZATION [=22] 时，您要从 table ORGANIZATION 中删除=] 通过 FK_JNCMPQJWFCJEXX62EA1P06VLP 外键。
你们有破解数据库的特殊代码吗？如果没有，您可能需要明确地编写它，或者如果您的业务要求允许，则将您的外键定义为 ON DELETE CASCADE。
我通过指定 type = DatabaseOperation.REFRESH 更改了 DbUnit 的行为。现在它不会在测试后清理数据库并且没有 JDBC 异常。
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { TestH2Config.class })
@TestExecutionListeners({
DependencyInjectionTestExecutionListener.class,
DirtiesContextTestExecutionListener.class,
TransactionDbUnitTestExecutionListener.class
})
@Transactional
public class BookServiceIT {
// ... dependencies injection goes here (omitted for brevity)
@Test
@DatabaseSetup(value = "/datasets/import.xml", type = DatabaseOperation.REFRESH)
public void testCase1() throws Exception {
// .. create Book in Organization(id=2)
// ... read and create data in database (omitted for brevity)
// .. delete the Book
}
}
请参阅 @DatabaseSetup 文档。
dbUnit 按照数据集文件中列出的数据的相反顺序删除行。确保文件的外键行位于关系的主要 keys/one 侧之后。
更新：
测试中存在一本书 table 行，所以告诉 dbUnit 也将其删除。一种方法是将外键 table 的空 table 添加到数据集文件 after 主 table:
<book/>
所以 dbUnit 拆卸操作看到 table 并且也将其清理。
