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

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); } }

我不知道现在回答是否太晚。 我可以通过从spring引导中排除DataSourceAutoConfiguration来解决这个问题。

您还没有为Spring Boot提供足够的信息来自动配置数据源。为此，需要向应用程序添加一些属性。属性与弹簧。数据源前缀。查看DataSourceProperties以查看您可以设置的所有属性。

你需要提供适当的url和驱动程序类名:

spring.datasource.url = …
spring.datasource.driver-class-name = …

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。

我解决了我的问题，只需添加@AutoConfigureTestDatabase(replace= replace . none)

@RunWith(SpringRunner.class)
@DataJpaTest
@AutoConfigureTestDatabase(replace=Replace.NONE)
public class TestClienteRepository {

}

如果你真的需要“spring-boot-start -data-jpa”作为你的项目依赖项，同时你又不想让你的应用访问任何数据库，你可以简单地排除自动配置类

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
