これは、私のウェブアプリを実行しようとしたときにスローされるエラーです。

の組み合わせが正しいと思っています。 datanucleus-appengine と datanucleus jarを使用します。

2.1: DataNucleus 3.1.x (core, api-jdo, api-jpa, enhancer)が必要です。SDK 1.6.4+が必要です。 このリリースのDatanucleusはもうリリースされていません。 DataNucleusプロジェクトでサポートされています。

JPAアプリの設定。 

@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();
    }
}

アプリケーション.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";
    }

}

私のアプリには何が欠けているのだろう？私はここからの指示に従いました Google AppengineでSpring Data JPAを使用する場合

どのように解決するのですか？

を自動構成するのに十分な情報をSpring Bootに与えていない。 DataSource . これを行うには、いくつかのプロパティを application.properties と共に spring.datasource の接頭辞があります。を見てみましょう。 データソースプロパティ をクリックすると、設定可能なすべてのプロパティを見ることができます。

適切なurlとドライバクラス名を指定する必要があります。 

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