Kotlin-LateInit TestRestTemplate未初始化集成测试

Question

我有一个使用kotlin开发的spring-boot应用程序--总体来说一切都很顺利。（spring 1.5.6.发行版，kotlin 1.1.4-3)

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")
    }
}

我尝试过的一些addl方法：-确保我没有使用不推荐的TestRestTemplate-尝试使用setter注入而不是field注入，但这是浪费时间。-禁用kotlin编译器插件

Spring Boot不会自动实例化TestRestTemplatebean（杜！）。

您需要自己定义它，然后您将能够使用它。

@Bean
open fun restTemplate(): TestRestTemplate {
    return TestRestTemplate()
}
