使用Spring JPA / Hibernate中的配置文件创建EmbeddedDataSource以进行测试时出错

Question

我正在尝试使用JUnit和embeddedDataSource测试我的简单应用程序（Spring JPA / Hibernate）（是的，我知道这应该通过整体测试来完成）。当我将spring配置文件引入我的项目并尝试在测试中创建嵌入式dataSource时，我得到了这个例外：

我的配置：

@Configuration
@PropertySource("classpath:db.properties")
@EnableTransactionManagement
public class JdbcConfig
{

    @Resource
    public Environment env;


    @Bean
    @Profile("prod")
    public DataSource dataSource()
    {
        System.out.println(env);
        DriverManagerDataSource ds = new DriverManagerDataSource();
        ds.setDriverClassName(env.getProperty("dataSource.driverClassName"));
        ds.setUrl(env.getProperty("dataSource.Url"));
        ds.setUsername(env.getProperty("dataSource.username"));
        ds.setPassword(env.getProperty("dataSource.password"));
        return ds;

    }

    @Bean
    @Profile("test")
    public DataSource embeddedDataSource()
    {
        return new EmbeddedDatabaseBuilder()
                .setType(EmbeddedDatabaseType.H2)
                .build();
    }



    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean(DataSource ds, JpaVendorAdapter jpaVendorAdapter)
    {
        LocalContainerEntityManagerFactoryBean emfb = new LocalContainerEntityManagerFactoryBean();
        emfb.setDataSource(ds);
        emfb.setJpaVendorAdapter(jpaVendorAdapter);
        emfb.setPackagesToScan("app.model");
        return emfb;
    }

    @Bean
    public JpaVendorAdapter jpaVendorAdapter()
    {
        HibernateJpaVendorAdapter adapter = new HibernateJpaVendorAdapter();
        adapter.setDatabase(Database.POSTGRESQL);
        adapter.setShowSql(true);
        adapter.setGenerateDdl(true);
        adapter.setDatabasePlatform(env.getProperty("dataSource.dialect"));

        return adapter;
    }



    @Bean
    public BeanPostProcessor beanPostProcessor()
    {
        return new PersistenceExceptionTranslationPostProcessor();
    }


    @Bean
    public JpaTransactionManager jpaTransactionManager(EntityManagerFactory em)
    {
        return new JpaTransactionManager(em);
    }


}

缺少bean @PropertyContext在其他配置文件中。我的测试看起来像这样：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = RootConfig.class)
@ActiveProfiles("test")
public class UserRepositoryTest
{
    @Inject
    UserDAO dao;


    @Test
    public void injectionDAOTest()
    {
        assertThat(dao,not(nullValue()));
    }

}

正如你所看到的那样，在hibernate中设置了属性 - generateDdl，但它仍然无法正常工作。这个错误的根源是什么？

问题解决了。我没有在jpaVendorAdapter

中配置正确的数据库类型
