Question

我用Spring和JDBC开发了一个项目，现在我正在尝试使用JPA配置我的Spring应用程序，我正在学习本教程。我在getObject()方法geJpaTransactionManager下收到错误。我已经提到了所有提到的JAR。我在这里错过任何东西吗？

@Configuration
@EnableWebMvc
@EnableTransactionManagement
@ComponentScan(basePackages = "net.jpa.spring")
public class AppConfig{

 @Bean
   public LocalEntityManagerFactoryBean getEntityManagerFactoryBean() {
      LocalEntityManagerFactoryBean factoryBean = new LocalEntityManagerFactoryBean();
      factoryBean.setPersistenceUnitName("LOCAL_PERSISTENCE");
      return factoryBean;
   }

   @Bean
   public JpaTransactionManager geJpaTransactionManager() {
      JpaTransactionManager transactionManager = new JpaTransactionManager();
      transactionManager.setEntityManagerFactory(getEntityManagerFactoryBean().getObject()); --> Getting error here
      return transactionManager;
   }

}

错误是

The method getObject() from the type AbstractEntityManagerFactoryBean refers to the missing type EntityManagerFactory

Answer 1

我认为您可能没有导入hibernate-jpa。 Miber依赖项对于hibernate-jpa如下。这就是为什么编译器无法检测到EntityManagerFactory的原因。

<!-- https://mvnrepository.com/artifact/org.hibernate.javax.persistence/hibernate-jpa-2.0-api -->
<dependency>
    <groupId>org.hibernate.javax.persistence</groupId>
    <artifactId>hibernate-jpa-2.0-api</artifactId>
    <version>1.0.1.Final</version>
</dependency>

无法使用Spring配置JPA
