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
这是尝试运行我的Web应用程序时引发的错误:

我相信我有正确的组合datanucleus-appengine和datanucleus罐子:
2.1:需要DataNucleus 3.1.x(core,api-jdo,api-jpa,enhancer).需要SDK 1.6.4+请注意,DataNucleus项目不再支持此版本的Datanucleus
JPA App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";
}
}

我想知道我的应用程序中可能缺少什么？我按照这里的说明在Google Appengine上使用Spring Data JPA

如果您想使用Spring Boot的嵌入式H2数据库,请将以下依赖项添加到您的pom文件中.
<dependency> <groupId>com.h2database</groupId> <artifactId>h2</artifactId> <version>1.3.156</version> </dependency>但正如评论中所提到的,嵌入式H2数据库将数据保存在内存中,并且不会永久存储它.

您没有为Spring Boot提供足够的信息来自动配置a
DataSource.为此,您需要application.properties使用spring.datasource前缀添加一些属性.查看DataSourceProperties以查看可以设置的所有属性.您需要提供相应的URL和驱动程序类名称:
spring.datasource.url = … spring.datasource.driver-class-name = …

我有同样的问题,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); } }2023-01-11 13:22 回答

现在我仔细观察,我认为DataSource问题是一个红色的鲱鱼.正在触发Boot的Hibernate自动配置,这就是导致需要DataSource的原因.Hibernate位于类路径上,因为你依赖于
spring-boot-starter-data-jpa它所引入的依赖hibernate-entitymanager.更新您的
spring-boot-starter-data-jpa依赖项以排除Hibernate:<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> <exclusions> <exclusion> <groupId>org.hibernate</groupId> <artifactId>hibernate-entitymanager</artifactId> </exclusion> </exclusions> </dependency>2023-01-11 13:24 回答

Spring启动将在application.properties文件中查找datasoure属性.
请在application.properties或yml文件中定义它
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,可以设置自己的配置文件,并在创建bean时使用数据源值.

你可以加
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
到你的
application.properties文件.2023-01-11 13:24 回答

如果回答为时已晚,我不会这样做.我可以通过从Spring引导中排除DataSourceAutoConfiguration来解决这个问题.

我在使用Spring Data为ElasticSearch编写API时遇到了此异常。我做了以下工作。

这对我有用(1.3.0.M5):
import org.springframework.boot.autoconfigure.jdbc.*; import org.springframework.boot.autoconfigure.orm.jpa.*; @Configuration @EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class}) public class Application {排除这两个类.
它没有用
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})2023-01-11 13:24 回答

从Spring手册.
Spring Boot可以自动配置嵌入式H2,HSQL和Derby数据库.您不需要提供任何连接URL,只需包含对要使用的嵌入式数据库的构建依赖关系.
例如,典型的POM依赖关系是:
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> <dependency> <groupId>org.hsqldb</groupId> <artifactId>hsqldb</artifactId> <scope>runtime</scope> </dependency>对于我来说,抛弃spring-boot-starter-data-jpa依赖关系,只使用spring-boot-starter-jdbc依赖就像魅力一样,只要我将h2(或hsqldb)作为依赖项包含在内.
