Autowired Spring数据存储库w/H2数据库处于测试中，未将实体表或字段转换为预期的Hibernate命名策略 问题

我有一个Spring配置类，用于生成内存中的H2数据库以进行集成测试。我还有一个集成测试，应该使用H2数据库来实现它的方法。其中一个测试，一个原始JDBC查询，成功了，所以我知道数据库至少部分是由脚本生成的。但是，JPA实体（假定其名为SampleThing并具有相应的SampleThingRepository）在生成SQL时似乎没有使用正确的命名策略

在文件IntegrationConfigTest中，我定义了两个测试：

• IntegrationConfigTest.verifyEmbeddedDatabase（通过）
• IntegrationConfigTest.ormMappingShouldWork（失败，出现异常org.h2.jdbc.JdbcSQLException:未找到表“sampleThings；”）

期望值

• 我期望存储库方法findOne（1L）为SQL生成什么：
  • 选择samplethin0\u0.id作为id1\u 6\u 0\u0，samplethin0.is\u active as\u active2\u 6\u 0\u0，samplethin0.name作为name3\u 6\u 0\u0，samplethin0.list\u order作为testDb.samplethin中的list\u4\u 6\u 0\u0\u0，其中samplethin\u0.id=
• 它实际上产生了什么：
  • 从testDb.sampleThings sampleThings中选择samplethin0.id作为id1_6_0_，samplethin0.isActive作为isActive2_6_0_，samplethin0.name作为name3_6_0_，samplethin0_。listOrder作为ListOrder4_6_0_

在IntegrationConfig中，我将hibernate.naming_策略定义为改进的命名策略（这正是我想要的）。您可以假设我的实体样本指定了一个表名和列名，以驼峰形式表示，应该将其转换为snake形式。任何帮助都将不胜感激

文件夹 下面是IntegrationConfig，我的配置设置H2数据库：

@Ignore("Not a test")
@Configuration
@EnableJpaRepositories("com.company.project.repository")
public class IntegrationConfig {
    @Value("classpath:checks_off.sql")
    private Resource checksOffScript;

    @Value("classpath:set_mode.sql")
    private Resource setModeScript;

    @Value("classpath:test_schema.sql")
    private Resource schemaScript;

    @Value("classpath:test_import.sql")
    private Resource importScript;

    @Value("classpath:checks_on.sql")
    private Resource checksOnScript;

    @Bean
    public DataSource dataSource() {
        DataSourceBuilder dataSourceBuilder = DataSourceBuilder.create();
        dataSourceBuilder.url("jdbc:h2:mem:testDb;DB_CLOSE_DELAY=-1;MODE=Mysql;DATABASE_TO_UPPER=false");
        dataSourceBuilder.driverClassName("org.h2.Driver");
        return dataSourceBuilder.build();
    }

    @Bean
    public DataSourceInitializer dataSourceInitializer() {
        final DataSourceInitializer initializer = new DataSourceInitializer();
        initializer.setDataSource(dataSource());
        initializer.setDatabasePopulator(databasePopulator());
        return initializer;
    }

    private DatabasePopulator databasePopulator() {
        final ResourceDatabasePopulator populator = new ResourceDatabasePopulator();
        populator.addScript(checksOffScript);
        populator.addScript(setModeScript);
        populator.addScript(schemaScript);
        populator.addScript(importScript);
        populator.addScript(checksOnScript);
        return populator;
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
        entityManagerFactoryBean.setDataSource(dataSource());
        entityManagerFactoryBean.setPackagesToScan("com.company.project");
        entityManagerFactoryBean.setJpaProperties(getPropeties());
        entityManagerFactoryBean.setJpaVendorAdapter(getJpaVendorAdapter());
        return entityManagerFactoryBean;
    }

    private Properties getPropeties(){
        Properties properties = new Properties();
        properties.put("hibernate.current_session_context_class", SpringSessionContext.class.getName());
        properties.put("hibernate.default_schema", "testDb");
        properties.put("hibernate.naming_strategy", org.hibernate.cfg.ImprovedNamingStrategy.class.getName());
        return properties;
    }


    private JpaVendorAdapter getJpaVendorAdapter(){
        HibernateJpaVendorAdapter adapter = new HibernateJpaVendorAdapter();
        adapter.setDatabase(Database.H2);
        adapter.setGenerateDdl(true);
        adapter.setShowSql(true);
        return adapter;
    }

    @Bean
    public PlatformTransactionManager transactionManager() {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(entityManagerFactory().getObject());
        return transactionManager;
    }
}

下面是IntegrationConfigTest，该类包含两个测试：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = IntegrationConfig.class)
public class IntegrationConfigTest {


    JdbcTemplate jdbcTemplate;

    @Autowired
    SampleThingRepository sampleThingRepository;

    @Autowired
    DataSource dataSource;


    @Before
    public void setUp() {
        jdbcTemplate = new JdbcTemplate(dataSource);
    }


    String getThingByOrder(int order) {
        return jdbcTemplate.queryForObject(
                "SELECT name FROM sample_things WHERE list_order = ?",
            String.class, order);
    }


    @Test
    public void verifyEmbeddedDatabase() {
        String firstThing = getThingByOrder(1);
        assertThat(firstThing, is("This thing"));

        String secondThing = getThingByOrder(2);
        assertThat(secondThing, is("That thing"));
    }


    @Test
    public void ormMappingShouldWork() {
        SampleThing sampleThing = sampleThingRepository.findOne(1L);
        assertThat(sampleThing.getName(), is("This thing"));
        assertThat(sampleThing.getOrder(), is(1));
    }
}

似乎没有应用您的

NamingStrategy

。将

hibernate.naming_策略

更改为

hibernate.ejb.naming_策略

，使您的hibernate属性如下所示：

properties.put("hibernate.ejb.naming_strategy", org.hibernate.cfg.ImprovedNamingStrategy.class.getName());
