我相信我有正确的 datanucleus组合-appengine 和 datanucleus jar：


<2.1>需要DataNucleus 3.1.x（核心，api-jdo，api-jpa，增强器）。需要SDK 1.6.4+请注意，DataNucleus项目不再支持Datanucleus的这个版本
。 JPA App Config： 

  @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）; 
退货工厂; 
 
 @Bean 
 Public PlatformTransactionManager transactionManager（）{
 logger.info（Loading Transaction Manager ...）; 
 JpaTransactionManager txManager = new JpaTransactionManager（）; 
 txManager.setEntityManagerFactory（entityManagerFactory（）。getObject（））; 
返回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（）{
 returnHello World; 
} 
 
}

我想知道在我的应用程序中可能会丢失什么？我遵循这里的在Google Appengine上使用Spring Data JPA < 你没有提供足够的信息来自动配置 DataSource 。为此，您需要使用 spring.datasource 前缀将一些属性添加到 application.properties 中。看看 DataSourceProperties 查看您可以设置的所有属性。



您需要提供适当的网址和驱动程序类名称： 

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

I believe I have the right combination of datanucleus-appengine and datanucleus jars:

2.1: Requires DataNucleus 3.1.x (core, api-jdo, api-jpa, enhancer). Requires SDK 1.6.4+ Note that this release of Datanucleus is no longer supported by the DataNucleus project

JPA App Config:

@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";
    }

}

I wonder what could be missing in my app? I followed the instruction from here Using Spring Data JPA on Google Appengine

解决方案

You haven't provided Spring Boot with enough information to auto-configure a DataSource. To do so, you'll need to add some properties to application.properties with the spring.datasource prefix. Take a look at DataSourceProperties to see all of the properties that you can set.

You'll need to provide the appropriate url and driver class name:

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

这篇关于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的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
