Question

创建名称为'companyRepositoryImpl'的bean时出错：持久性依赖项注入失败；嵌套的异常是org.springframework.beans.factory.NoSuchBeanDefinitionException：没有类型为'javax.persistence.EntityManagerFactory'的合格Bean

我正在通过Spring Security和OAuth2学习Spring REST，以下是链接： https://dzone.com/articles/secure-spring-rest-with-spring-security-and-oauth2

使用DB作为Postgres。

companyRepositoryImpl.class

@Repository
public class CompanyRepositoryImpl implements CompanyRepository {


    //@Autowired
    //@Qualifier(value = "transactionManager")
    @PersistenceContext
    private EntityManager entityManager;

    @Override
    public Company find(Long id) {
        CriteriaBuilder builder = entityManager.getCriteriaBuilder();
        CriteriaQuery<Company> query = builder.createQuery(Company.class);

        Root<Company> root = query.from(Company.class);
        root.fetch(Company_.cars, JoinType.LEFT);
        Fetch<Company, Department> departmentFetch = root.fetch(Company_.departments, JoinType.LEFT);
        Fetch<Department, Employee> employeeFetch = departmentFetch.fetch(Department_.employees, JoinType.LEFT);
        employeeFetch.fetch(Employee_.address, JoinType.LEFT);
        departmentFetch.fetch(Department_.offices, JoinType.LEFT);

        query.select(root).distinct(true);
        Predicate idPredicate = builder.equal(root.get(Company_.id), id);
        query.where(builder.and(idPredicate));

        return DataAccessUtils.singleResult(entityManager.createQuery(query).getResultList());
    }

HibernateConfiguration.class

package com.adamzareba.spring.security.oauth2.config;
import com.fasterxml.jackson.databind.Module;
import com.fasterxml.jackson.datatype.hibernate5.Hibernate5Module;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor;
import org.springframework.orm.jpa.JpaTransactionManager;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import javax.persistence.EntityManagerFactory;

@Configuration
@EnableTransactionManagement
public class HibernateConfiguration {

    @Bean
    public Module hibernate5Module() {
        return new Hibernate5Module();
    }

    /**
     * Creates the transaction manager bean that integrates the used JPA provider with the
     * Spring transaction mechanism.
     * @param entityManagerFactory  The used JPA entity manager factory.
     * @return
     */
    @Bean
    //@Qualifier(value = "transactionManager")
    public PlatformTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(entityManagerFactory);

        return transactionManager;
    }

    @Bean
    public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
        return new PersistenceExceptionTranslationPostProcessor();
    }
}

我也尝试了以下更改，但是没有运气，而不是@PersistenceContext

@Autowired
@Qualifier(value = "transactionManager")
private EntityManager entityManager;

和

@Bean
@Qualifier(value = "transactionManager")
public PlatformTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
}

持久性依赖项的注入失败：没有可用的'javax.persistence.EntityManagerFactory'类型的合格Bean
