DBUnit如何设置属性以测试在Docker容器中运行的数据库

Question

我正在构建一个使用MySQL数据库的Spring Boot应用程序。我可以使用DBUnit运行集成测试来测试数据库，但如果我在Docker容器中运行相同的数据库，则DBUnit会因错误而失败：

org.dbunit.dataset.NoSuchTableException: Did not find table 'spring_session_attributes' in schema 'null'

我的架构中的每个表都会抛出此错误。请注意，当我运行没有Docker的数据库时，不会出现此问题。

同时我可以通过MySQL Workbench访问Docker容器中的数据库，我看到数据库存在且所有表都存在。我在测试中的设置是：

@Before
    public void setup() {
       System.setProperty(PropertiesBasedJdbcDatabaseTester.DBUNIT_DRIVER_CLASS,
                "com.mysql.jdbc.Driver");
     System.setProperty(PropertiesBasedJdbcDatabaseTester.DBUNIT_CONNECTION_URL,
                "jdbc:mysql://localhost:3306/portal");
        System.setProperty(PropertiesBasedJdbcDatabaseTester.DBUNIT_USERNAME,
                "root");
        System.setProperty(PropertiesBasedJdbcDatabaseTester.DBUNIT_PASSWORD,
                "pass");
        System.setProperty(PropertiesBasedJdbcDatabaseTester.DBUNIT_SCHEMA,
                "portal");

        ...
    }

似乎问题应该在连接jdbc:mysql://localhost:3306/portal的某个地方，但我不确定，因为它似乎建立了连接，但“对话”被打破了。我必须提一下，项目本身可以正常工作，数据库位于Docker容器中。如果有人可以帮助我或指导一下，我将不胜感激。

DBUnit不支持包装盒中版本高于5.1的mysql-connector-java！

我们使用自定义DBUnit的org.dbunit.ext.mysql.IMetadataHandler（DefaultMetaDataHandler和MysqlMetaDataHandler之间的东西，混合的方法）运行Spring Boot 2.1.3，mysql-connector-java 8.0.15，database-rider 1.5.2。 MySQL数据库在docker中。工作良好。
