Spring Boot -无法确定数据库类型为NONE的嵌入式数据库驱动程序类

这是在试图运行我的web应用程序时抛出的错误:

我相信我有datannuclear -appengine和datanucleus jars的正确组合:

2.1:需要DataNucleus 3.1。X(核心，api-jdo, api-jpa，增强器)。需要SDK 1.6.4+注意，这个版本的Datanucleus不再 由DataNucleus项目支持

JPA应用程序配置:

@Configuration
@EnableJpaRepositories("demo.core.entity")
@EnableTransactionManagement
class JpaApplicationConfig {
    private static final Logger logger = Logger
            .getLogger(JpaApplicationConfig.class.getName());
    @Bean
    public AbstractEntityManagerFactoryBean entityManagerFactory() {
        logger.info("Loading Entity Manager...");
        LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
        factory.setPersistenceUnitName("transactions-optional");
        return factory;
    }
    @Bean
    public PlatformTransactionManager transactionManager() {
        logger.info("Loading Transaction Manager...");
        JpaTransactionManager txManager = new JpaTransactionManager();
        txManager.setEntityManagerFactory(entityManagerFactory().getObject());
        return txManager;
    }
    @Bean
    public PersistenceExceptionTranslator persistenceExceptionTranslator() {
        return new OpenJpaDialect();
    }
}

Application.java

@Configuration
@ComponentScan
@EnableAutoConfiguration
@RestController
public class Application {

    private static final EntityManagerFactory INSTANCE =
            Persistence.createEntityManagerFactory("transactions-optional");

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @RequestMapping("/")
    public String home() {
        return "Hello World";
    }

}

我想知道在我的应用程序中会缺少什么?我遵循从这里使用Spring Data JPA在谷歌Appengine的说明

当前回答

如果这些都不起作用，尝试创建一个Repository类以及RepositoryInterface， 虽然spring boot应该自动生成一个实现类， 这对我来说很管用。

其他回答

在我的例子中，使用IDEA，删除out目录后，一切恢复正常。我也不知道为什么，但还是成功了。

献给那些在几小时后把头撞到墙上后来到这个帖子的人。我通过改变解决了这个错误

create table `group`(
    id char(19) primary key
);

to 

create table if not exists `group`(
    id char(19) primary key
);

在我的图式中。资源目录下的SQL文件。

使用下面的依赖项。

<dependency>
   <groupId>com.h2database</groupId>
   <artifactId>h2</artifactId>
   <scope>runtime</scope>
</dependency>

Answer is very simple, SpringBoot will look for Embeddable database driver, If you didn't configure in any of your configuration in form of XML or Annotations, it will throws this exception. Make the changes in your annotation like this @EnableAutoConfiguration(exclude=DataSourceAutoConfiguration.class) this will exclude the DataSourceAutoConfiguration. And the Perfect Simple Coding completion would be work if you have properly configured your class. @Controller @EnableAutoConfiguration(exclude=DataSourceAutoConfiguration.class) public class SimpleController { @RequestMapping("/") @ResponseBody String home() { return "Hello World!"; }public static void main(String[] args) throws Exception { SpringApplication.run(SimpleController.class, args); } }

Spring引导将在应用程序中查找数据源属性。属性文件。

请在应用中定义它。属性或yml文件

application.properties

spring.datasource.url=xxx
spring.datasource.username=xxx
spring.datasource.password=xxx
spring.datasource.driver-class-name=xxx

如果您需要自己的配置，您可以在创建bean时设置自己的概要文件并使用数据源值。
