如何让Eclipselink在Spring Boot应用程序中运行

Question

将我的启动日志复制到一个要点,因为它对于SE来说太长了.

这是我怀疑的信息的重要部分.

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'entityManagerFactory' is defined
at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:641)
at org.springframework.beans.factory.support.AbstractBeanFactory.getMergedLocalBeanDefinition(AbstractBeanFactory.java:1157)

at org.springframework.beans.factory.support.BeanDefinitionValueResolver.resolveReference(BeanDefinitionValueResolver.java:328)
... 145 more

这也是我的 pom.xml

我正在使用IDEA,内置"make"来编译和启动应用程序.

我尝试添加这个类,但似乎没有帮助

class EntityManagerFactoryProducer {

@Produces
@ApplicationScoped
public EntityManagerFactory createEntityManagerFactory() {
  return Persistence.createEntityManagerFactory("my-presistence-unit");
}

public void close(@Disposes EntityManagerFactory entityManagerFactory) {
  entityManagerFactory.close();
}

@Produces
@RequestScoped
public EntityManager createEntityManager(EntityManagerFactory entityManagerFactory) {
  return entityManagerFactory.createEntityManager();
}

public void close(@Disposes EntityManager entityManager) {
  entityManager.close();
}
}

我遇到了类似的问题，收到了相同的 No bean named 'entityManagerFactory' is Defined 异常。我的解决办法是在我的配置类中定义 bean。

@Configuration
public class JpaConfiguration extends JpaBaseConfiguration {
...
    @Bean
    public EntityManagerFactory entityManagerFactory() {
        return Persistence.createEntityManagerFactory("my-persistence-unit");
    }
}
