Spring Boot 3：容器启动后才能获取映射端口

Question

我最近将基于 Kotlin 的 Spring Boot 应用程序从版本 2.x 升级到版本 3.3.4，现在可以成功运行。

这是我的 Kotlin 测试用例：

package me.xxxxx.businessservice.controller

import org.junit.jupiter.api.BeforeAll
import org.junit.jupiter.api.Test
import org.junit.jupiter.api.extension.ExtendWith
import org.mockito.Mockito
import org.springframework.boot.test.autoconfigure.web.reactive.AutoConfigureWebTestClient
import org.springframework.boot.test.mock.mockito.MockBean
import org.springframework.http.MediaType
import org.springframework.test.context.DynamicPropertyRegistry
import org.springframework.test.context.DynamicPropertySource
import org.springframework.test.context.junit.jupiter.SpringExtension
import org.testcontainers.containers.PostgreSQLContainer
import org.testcontainers.junit.jupiter.Container
import org.testcontainers.junit.jupiter.Testcontainers
import reactor.core.publisher.Mono
import java.math.BigDecimal

@Testcontainers
@ExtendWith(SpringExtension::class)
@AutoConfigureWebTestClient
class ControllerTests : BaseIntegrationTest() {

    @MockBean
    protected lateinit var privilegeService: PrivilegeService


    companion object {

        @Container
        val container = PostgreSQLContainer<Nothing>("postgres:14").apply {
            withDatabaseName("servito")
            withUsername("admin")
            withPassword("test")
        }

        @JvmStatic
        @DynamicPropertySource
        fun properties(registry: DynamicPropertyRegistry) {
            registry.add("spring.datasource.url", container::getJdbcUrl)
            registry.add("spring.datasource.password", container::getPassword)
            registry.add("spring.datasource.username", container::getUsername)
        }

    }

    @Test
    fun createOrder() {
        //testcode
    }

}


@ActiveProfiles("test")
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
class BaseIntegrationTest(){

}

该错误意味着在 Spring 尝试访问 JdbcUrl 之前 Testcontainer 可能尚未完全启动。这可能是由于 Spring 应用程序上下文过早启动造成的，还是 Spring Boot 3.x 中 @DynamicPropertySource 的计时存在问题？

Spring Boot 3.x 中测试容器的设置是否发生了变化？

在 Testcontainers 完全初始化之前，应用程序上下文是否启动得太早？

Answer 1

正如您可以在这篇 spring-boot 文章以及测试容器文档中阅读的那样，Spring Boot3 与测试容器中使用的注释进行了一些更新。

你必须替换这段代码

companion object {

    @Container
    val container = PostgreSQLContainer<Nothing>("postgres:14").apply {
        withDatabaseName("servito")
        withUsername("admin")
        withPassword("test")
    }

    @JvmStatic
    @DynamicPropertySource
    fun properties(registry: DynamicPropertyRegistry) {
        registry.add("spring.datasource.url", container::getJdbcUrl)
        registry.add("spring.datasource.password", container::getPassword)
        registry.add("spring.datasource.username", container::getUsername)
    }

}

与

companion object {

    @Container
    @JvmStatic
    @ServiceConnection
    val container = PostgreSQLContainer<Nothing>("postgres:14").apply {
        withDatabaseName("servito")
        withUsername("admin")
        withPassword("test")
    }

}
