MySQL TestContainers 初始化腳本架構創建失敗

Question

嘗試在 MySQL 測試容器實例中創建架構時遇到以下問題。 似乎測試用戶沒有適當的權限？

配置：

spring.datasource.driver-class-name=org.testcontainers.jdbc.ContainerDatabaseDriver
spring.datasource.url=jdbc:tc:mysql:5.7.22:///test?TC_INITSCRIPT=component/db/init_mysql.sql

Caused by: org.testcontainers.ext.ScriptUtils$UncategorizedScriptException: Failed to execute database script from resource [create schema new_schema CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;]

組件/db/init_mysql.sql

create schema new_schema CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

在 JDBC 集成之外創建 mysql 映像時看到類似問題：

private static final MySQLContainer mysqlContainer = new MySQLContainer<>(DockerImageName.parse("mysql:5.7"))
            .withInitScript("component/db/init_mysql.sql")
            .withUsername("user")
            .withPassword("password")
            .withExposedPorts(3306)
            .withReuse(true);

關於如何在不使用預先創建的架構創建自定義 docker 圖像的情況下實現這一目標的任何想法？

任何幫助將不勝感激我覺得我必須在這里遺漏一些東西。

Answer 1

嘗試創建whatever容器並使用與test用戶相同的root密碼，在本例中為 .

@Container
private static MySQLContainer database = new MySQLContainer(MYSQL_DOCKER_TEST_VERSION)
            .withUsername("test")
            .withPassword("whatever")
...

通過@DynamicPropertySource 動態添加屬性。

    @DynamicPropertySource
    static void databaseProperties(DynamicPropertyRegistry registry) {
        registry.add("spring.datasource.url", database::getJdbcUrl);
        registry.add("spring.datasource.username", database::getUsername);
        registry.add("spring.datasource.password", database::getPassword);
        registry.add("flyway.user", () -> "root");
        registry.add("flyway.password", database::getPassword);
    }

我沒有使用flyway，但我相信它應該可以工作。

通過使用預先創建的模式創建自定義 MySQL 映像來解決此問題。 很想聽聽是否有更好的方法。

Answer 3

正如在 testcontainers 存儲庫上創建的測試中所見，解決方法是指定 root 用戶的密碼並在測試中使用 root 用戶：

MySQLContainer<?> db = new MySQLContainer<>(image)
            .withUsername("test")
            .withPassword("test")
            .withEnv("MYSQL_ROOT_PASSWORD", "test")
            ...

Answer 4

我遇到了同樣的問題，我使用以下方法解決了它：

    @Container
     public static JdbcDatabaseContainer mariaDB = (JdbcDatabaseContainer) new MariaDBContainer("mariadb:10.5.11-focal")
    .withDatabaseName("dbName")
    .withInitScript("db.migration/init.sql")
    .withUsername("your user")
    .withPassword("your password")
    .withUrlParam("param", "1")
    .withUrlParam("param", "2");

基本上，我通過 POJO 創建數據庫。 有點hackish但有效。 但也許使用自定義密碼創建 root 用戶是一個更好的解決方案。
