多思不若养志，多言不若守静，多才不若蓄德。——曾国藩

我在 ob-samples 添加的 demo 合并了

https://github.com/oceanbase/ob-samples/pull/37

通过 mybatisplus-java 启动和测试 OceanBase Docker
容器，更多详细信息可以参见 https://github.com/baomidou/mybatis-plus
以及 https://java.testcontainers.org/modules/databases/oceanbase 。

快速开始

将 OceanBase 驱动、TestContainers OceanBase、MybatisPlusStarter、SpringBootStarter Test 模块添加到 POM。

以 MybatisPlusJavaApplicationTests.java
代码为例。

以下代码不仅实现了OceanBaseCEContainer的生命周期管理。 它将在执行任何测试用例之前启动容器实例，并在执行所有测试用例后停止容器，而且还在期间使用
ScriptUtils.executeSqlScript 执行数据库初始化 SQL。

@SpringBootTest
@Testcontainers
class MybatisPlusJavaApplicationTests {

  @Container
  public static OceanBaseCEContainer oceanBaseContainer = new OceanBaseCEContainer(DockerImageName.parse("oceanbase/oceanbase-ce:latest"))
    .withEnv("MODE", "slim")
    .withEnv("FASTBOOT", "true");
  @Autowired
  private PersonMapper personMapper;

  @DynamicPropertySource
  static void oceanBaseProperties(DynamicPropertyRegistry registry) {
    registry.add("spring.datasource.url", oceanBaseContainer::getJdbcUrl);
    registry.add("spring.datasource.username", oceanBaseContainer::getUsername);
    registry.add("spring.datasource.password", oceanBaseContainer::getPassword);
    registry.add("spring.datasource.driver-class-name", oceanBaseContainer::getDriverClassName);
  }

  @BeforeAll
  static void setup(@Autowired DataSource dataSource) throws Exception {
    JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);
    assertNotNull(jdbcTemplate.getDataSource());
    ScriptUtils.executeSqlScript(jdbcTemplate.getDataSource().getConnection(), new ClassPathResource("init.sql"));
  }
}

您可以在测试用例中使用 MybatisPlus 操作 OceanBase 实例，如下所示：

@Test
void testSelectList() {
  List<Person> persons = personMapper.selectList(null);
  assertFalse(persons.isEmpty());
}
