Spring Boot – 无法确定数据库types为NONE的embedded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datanucleus-appengine和datanucleusjar组合：

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Datanucleus的这个版本

JPA应用程序configuration：

 @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"; } }

我不知道我的应用程序可能会丢失什么？ 我遵循在这里使用Google Appengine上的Spring Data JPA的指令

Answer 1

您没有提供足够的信息来自动configurationDataSource Spring Boot。 为此，您需要使用spring.datasource前缀将一些属性添加到application.properties 。 看看DataSourceProperties看看你可以设置的所有属性。

您需要提供适当的url和驱动程序类名称：

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

Answer 2

我通过添加以下内容到我的pom文件来解决这个问题。

  <dependency> <groupId>com.h2database</groupId> <artifactId>h2</artifactId> <version>1.3.156</version> </dependency> 

Answer 3

我想同样的问题，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 4

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}) 

Answer 5

现在我仔细观察，我认为DataSource问题是一个红鲱鱼。 Boot的Hibernate自动configuration正在被触发，这就是导致需要DataSource的原因。 Hibernate的类path，因为你有依赖spring-boot-starter-data-jpa拉入hibernate-entitymanager 。

更新你的spring-boot-starter-data-jpa依赖来排除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> 

Answer 6

从春季手册 。

Spring Boot可以自动configurationembedded式H2，HSQL和Derby数据库。 您不需要提供任何连接URL，只需将构build依赖项包含到要使用的embedded式数据库中即可。

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> 

对于我而言，只要将h2（或hsqldb）作为依赖关系包含在spring-boot-starter-data-jpa依赖项中，并使用spring-boot-starter-jdbc依赖项就像一个魅力一样工作。

Answer 7

如果回答太晚，我不会。 我可以通过从弹簧引导中排除DataSourceAutoConfiguration来解决这个问题。

Answer 8

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 

如果你需要自己的configuration，你可以设置你自己的configuration文件，并在创buildbean时使用数据源值。

Answer 9

你可以添加spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration到你的属性文件

Answer 10

我有org.springframework.data groupId有两个依赖，然后我删除jpa，只保留mongodb，它的工作！

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

Answer 11

做下面的工作。

 @EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class}) 

但是，如果我想有dataSource，我不应该做上面的configuration。 下面的链接说我们需要在application.properties文件中的所有属性。 所有的属性应该从spring.datasource.*开始spring.datasource.*

http://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html

Answer 12

我在使用Spring Data为ElasticSearch执行API时遇到了这个exception。 我做了以下，它的工作。

 @SpringDataApplication(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class}) 

Answer 13

我从osbdLoggingFailureAnalysisReporter的标题中收到了错误消息，并显示“应用程序失败开始”消息。 事实certificate，我没有添加-Dspring.profiles.active=dev到我的Eclipsedebuggingconfiguration，所以我没有活动configuration文件。

Answer 14

我也面临同样的问题。

 Cannot determine embedded database driver class for database type NONE. 

在我的情况下删除从数据库相应的数据库中的jar文件修复了问题。 存在导致问题的存储库中存在损坏的jar。

Answer 15

在我的情况下，我把它放在我的pom中的org.jasig.cas的maven依赖项，它触发了一个hibernate的依赖，并导致Spring Boot寻找一个数据源来自动configurationhibernate的持久性。 我通过添加user672009build议的com.h2database maven dependency来解决这个问题。 多谢你们！

Answer 16

由于这是在谷歌返回这个错误的第一个主题之一，我会发布我所做的情况下，有人面临同样的问题..我不想排除DataSourceAutoConfiguration既不使用内存数据库..

在我的情况下，我设置的参数为其他repliers说，但application.properties文件是在错误的文件夹内..大声笑

所以如果没有这样的工作，检查文件是否在src/main/resources ！ 在我的情况是在src/main/resources/static

Answer 17

答案很简单，SpringBoot将查找Embeddable数据库驱动程序，如果您没有以XML或注解formsconfiguration您的任何configuration，则会抛出此exception。 像这样在注释中进行更改

 @EnableAutoConfiguration(exclude=DataSourceAutoConfiguration.class) 

这将排除DataSourceAutoConfiguration。 完美的简单编码完成将是工作，如果你有适当的configuration你的课堂。

 @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); } } 

Answer 18

我解决我的问题只是添加@AutoConfigureTestDatabase（replace= Replace.NONE）

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

Answer 19

您可以从Maven Repository下载derby-10.10.1.1.jar，并将其放在您的WEB-INF / lib文件夹中，就像这个Application / WEB-INF / lib / derby-10.10.1.1.jar一样。 您的embedded式AnnotationConfigEmbeddedWebApplicationContext将获取数据库驱动程序，您的Web服务器将开始运行，而不会有任何问题:-)

Answer 20

如果您使用的是Gradle，请包含如下的驱动程序jar：

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

或者，如果使用Maven，那么使用Maven风格，它应该可以解决你的问题。

Answer 21

几个小时后，你的头靠在墙上，对任何人来到这个线程。 我通过更改解决了这个错误

 create table `group`( id char(19) primary key ); 

至

 create table if not exists `group`( id char(19) primary key ); 

在资源目录中的我的schema.sql文件中。

Answer 22

如果您确实需要“spring-boot-starter-data-jpa”作为您的项目依赖项，并且同时您不希望允许您的应用程序访问任何数据库，则可以简单地排除自动configuration类

 @SpringBootApplication(exclude = DataSourceAutoConfiguration.class) 

Answer 23

即使在application.properties中提供了所有必需的数据源属性之后，我仍面临着这个问题。 然后我意识到，属性configuration类没有得到由Spring启动扫描，因为它是在不同的包层次结构相比，我的Spring引导Application.java，因此没有属性被应用到数据源对象。 我改变了我的属性configuration类的包名称，并开始工作。 https://stackoverflow.com/a/42368525/7598936
