Java @DirtiesContext不适用于Spring Boot和Kotlin

我试图在SpringBoot中运行一些集成测试。为此，我认为我们应该在每个测试运行后使用

@DirtiesContext

清理数据库

我现在试过几种方法，但都有同样的效果

这是我的设置：

• 弹簧护套1.5.10.1释放
• SQL Server 2016
• Kotlin 1.2.21

这是完整的POM：

LogMessageContent实体 存储库 存储库都非常标准

@Transactional
internal interface LogRepository : CrudRepository<LogEntity, Long>

@Transactional
internal interface LogReferenceRepository : CrudRepository<LogReferenceEntity, Long>

@Transactional
internal interface LogMessageContentRepository : CrudRepository<LogMessageContentEntity, Long>

不带任何参数的类上的

@DirtiesContext

使用

classMode

将实例保存到数据库的测试方法的

@DirtiesContext

使用

methodMode

我也尝试了一些其他的东西，但我有一种感觉，我离得不远了

---

有人能给我一个正确的方向吗？

您不需要使用

@DirtiesContext

来清除测试之间的数据库更改，尽管有时可能需要在测试类之间错误地共享应用程序上下文

相反；您应该将测试标记为

@Transactional

。这将确保每个测试方法都由Spring事务包装，不管结果如何，该事务都将回滚

    @Test
    @Transactional
    fun `'addLog' should return the created entity`() {
        val result = service.addLog(logCreateDTO = LogCreateDTO())
        assertThat(result).isNotNull()
        assertThat(result.id).isNotNull()
    }
