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

如果你正在使用Gradle，包括正确的驱动程序，如下所示:

compile("org.mongodb:mongo-java-driver:3.3.0")

或者如果使用Maven，那么按照Maven风格来做，它应该可以解决您的问题。

其他回答

我也有同样的问题，排除DataSourceAutoConfiguration解决了这个问题。

@SpringBootApplication
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
public class RecommendationEngineWithCassandraApplication {

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

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); } }

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。

我的应用程序文件没有被读取，Spring试图连接到一个嵌入式H2数据库(没有添加到pom中)。这将抛出以下错误消息:

如果要从特定配置文件加载数据库设置 您可能需要激活它(当前没有配置文件激活)。

通过下面的问题，确保您的应用程序文件正在被读取。

我对org.springframework的groupId有两个依赖。数据，然后我删除了jpa，只保留mongodb，它工作!

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-mongodb</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
</dependency>
