我有一个使用kotlin进行开发的spring-boot应用程序 - 总体情况进展顺利。 (春1.5.6.RELEASE,科特林1.1.4-3)Kotlin - lateinit TestRestTemplate无法初始化集成测试
反正我是将我的第一个控制器测试回顾一些示例代码后,和我遇到了这个恼人的错误:
kotlin.UninitializedPropertyAccessException :lateinit财产restTemplate尚未初始化

下面是测试类
import org.junit.runner.RunWith
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.boot.test.context.SpringBootTest
import org.springframework.boot.test.web.client.TestRestTemplate
import org.springframework.test.context.junit4.SpringRunner
import org.testng.Assert
import org.testng.annotations.Test
@RunWith(SpringRunner::class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
class ProductSetControllerTest {
@Autowired
lateinit var restTemplate: TestRestTemplate
@Test
fun testGet() {
val forObject = restTemplate.getForObject("/", String::class.java)
Assert.assertEquals(forObject, "gettest")
}
}
有些事情ADDL我已经试过: - 确保我没有使用过时TestRestTemplate - 使用setter注入,而不是字段注入试过,但浪费时间。 - 禁用kotlin编译器插件
也许我失去了一些东西,但是从javadoc的https://docs.spring.io/autorepo/docs/spring-boot/1.4.x-SNAPSHOT/api/org/springframework/boot/test /web/client/TestRestTemplate.html它说的是相反的“如果您使用的是SpringBootTest批注,TestRestTemplate自动可用,并且可以自动装入您的测试。” –
通过扩展AbstractTestNGSpringContextTests,也就是类ProductSetControllerTests:AbstractTestNGSpringContextTests(){ –
@michaelsalmon有趣,它用于不这样做 - 无论如何,我很高兴它解决了,我将尽快删除我的答案 –
