我正在尝试在 docker 容器中运行我的项目测试。在本地运行时,所有测试都工作得很好。当我尝试将测试移动到 docker 容器时,错误开始出现。 这是错误消息:
java.lang.IllegalStateException: Failed to load ApplicationContext

从日志中我们可以看到容器镜像已经创建,但是迁移sql schema失败:

这是sql脚本的一部分(app/src/main/resources/db/migration):

这里是“application.properties”(app/test/java/resources):

在同一目录中,我还有 container-license-acceptance.txt 文件。
在“build.gradle”中,我添加了以下几行 (app/build.gradle):
dependencies {
[...]
testImplementation "org.testcontainers:junit-jupiter:1.11.3"
testImplementation "org.testcontainers:postgresql:1.11.3"
}
在 BaseInitTest 文件中,我有以下几行 (app/test/java/com):
@Testcontainers
@SpringBootTest
public class BaseIntTest {
@Container
private static final PostgreSQLContainer<?> container = new PostgreSQLContainer<>();
[...]
我不明白,为什么同样的测试一开始可以通过,但是当我将它们移动到 docker 容器时却失败了?
最佳答案
看起来带有数据库的测试容器已成功启动,所以没有问题,您得到的是一个空数据库。
然后您尝试运行飞行路线,但失败了。 spring boot 中的 Flyway 在 spring application context 的初始化过程中工作, 因此实际迁移在应用程序上下文初始化时运行,因此迁移失败看起来像 Spring 故障。
但是,记录了原因:迁移文件的内容无效:
Migration V1__initial_user.sql failed

(
rev INTEGER GENERATED BY DEFAULT AS IDENTITY ( START WITH 1 ),

此 GENERATED BY
不受支持。
为什么?可能您的 docker 镜像包含不支持此语法的 RDBMS 版本。所以它不同于您在没有 docker 的本地环境中使用的数据库。
无论如何,这与 docker、spring 或 flyway 无关,而是与数据库和迁移代码有关。
在分辨率方面,我建议直接运行数据库的 docker 镜像(不使用 java、testcontainers 和 flyway)。 当它运行时,只需在 pgadmin 或其他东西中“手动”运行此迁移。您应该会看到相同的错误。
