这是对spring@datajpatest和junit5的扩展，主要区别在于添加了测试容器。
我试着在git回购样本中把事情保持在最低限度。
测试很直接
@DataJpaTest
@Testcontainers
@ContextConfiguration(classes = {
DemoApplicationTests.Config.class
})
@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
class DemoApplicationTests {
@Autowired
private Artifacts artifacts;
@Test
void contextLoads() {
assertThat(artifacts).isNotNull();
}
@Container
private static final MySQLContainer<?> MYSQL = new MySQLContainer<>("mysql:5.7");
@Configuration
static class Config {
@Bean
public DataSource dataSource() {
final DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setUrl(MYSQL.getJdbcUrl());
dataSource.setUsername(MYSQL.getUsername());
dataSource.setPassword(MYSQL.getPassword());
await().pollInterval(Duration.ofSeconds(2L))
.atMost(Duration.ofMinutes(2L))
.until(() -> {
try (final Connection c = dataSource.getConnection()) {
c.prepareStatement("select 1 from dual");
return true;
} catch (SQLException e) {
return false;
}
});
return dataSource;
}
}
}主要的应用程序我也保持在最低限度
@SpringBootApplication
@EnableTransactionManagement
@EnableJpaRepositories
@EntityScan
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}但运行测试时，我得到以下堆栈跟踪段：
Caused by: java.lang.IllegalStateException: Unable to retrieve @EnableAutoConfiguration base packages
at org.springframework.boot.autoconfigure.AutoConfigurationPackages.get(AutoConfigurationPackages.java:78)
at org.springframework.boot.autoconfigure.data.AbstractRepositoryConfigurationSourceSupport.getBasePackages(AbstractRepositoryConfigurationSourceSupport.java:79)

我找到了两种方法让它工作。一种方法是
从中加载配置
DemoApplication. 虽然它通常比较干净，但是如果您有其他服务，比如enableredisrepositories和enablekafka，测试仍然可能失败，因为这些资源可能没有在您的脚本中配置。或者
Config类可以启用，因此只执行jpa测试。这是我最终选择的，因为我在从中提取样本的代码上启用了redisrepositories。
