如何讓 Eclipselink 在 Spring Boot 應用程序中工作

Question

將我的啟動日志復制到要點，因為它對 SE 來說太長了。

我懷疑這是消息的重要部分。

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.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:280)

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

這也是我的pom.xml

我正在使用內置“make”的 IDEA 來編譯和啟動應用程序。

我嘗試添加這個 class，但它似乎沒有幫助

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();
}
}

Answer 1

我遇到了一個類似的問題，我收到了相同的 No bean named 'entityManagerFactory' is defined 異常。 我的修復是在我的配置 class 中定義 bean。

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