＆＃34;没有配置CurrentSessionContext＆＃34;当应用程序尝试在数据库中执行查询时

Question

在我目前的spring-boot项目中，当我尝试在数据库中进行查询时，通过我的dao类中的这个方法（它是我在开发的这个步骤中使用的唯一方法）：

public class Dao<E extends Model> {

    @Autowired
    private SessionFactory sessionFactory;

    ...

    @Transactional
    public E findByField(String field, String value) {
        return (E) sessionFactory.getCurrentSession().createQuery("from "+clazz.getSimpleName()+" where "+field+" = :data").setParameter("data", value).uniqueResult();
    }
}

我收到此错误：

从此服务类调用此方法：

@Component
public class AcessoService implements UserDetailsService {

    @Autowired
    private UsuarioDao usuario;

    @Override
    @Transactional
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        Usuario account = (Usuario) usuario.findByField("login", username);

    if(account==null)
        throw new UsernameNotFoundException("No such user: " + username);
    else if (account.getRole().isEmpty())
        throw new UsernameNotFoundException("User " + username + " has no authorities");

    List<Permission> lista = new ArrayList<Permission>();
    int max = account.getRole().size();
    for(int i=0; i<max; i++) {
        int max2 = account.getRole().get(i).getPermission().size();
        for(int j=0; j<max2; j++)
            lista.add(account.getRole().get(i).getPermission().get(j));
    }

    boolean accountIsEnabled = true;
    boolean accountNonExpired = true;
    boolean credentialsNonExpired = true;
    boolean accountNonLocked = true;

    return new User(account.getLogin(), account.getSenha(), accountIsEnabled, accountNonExpired, credentialsNonExpired, accountNonLocked, getAuthorities(lista));
    }
}

这是我的application.properties文件：

# jdbc.X
spring.datasource.driverClassName=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/mystore?charSet=LATIN1
spring.datasource.username=klebermo
spring.datasource.password=123

# hibernate.X
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.dialect=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.show-sql=false
spring.jpa.hibernate.ddl-auto=create-drop

我有这个配置类来设置sessionFactory bean：

@Configuration
public class HibernateConfig {
    @Bean
    public HibernateJpaSessionFactoryBean sessionFactory(EntityManagerFactory emf) {
         HibernateJpaSessionFactoryBean factory = new HibernateJpaSessionFactoryBean();
         factory.setEntityManagerFactory(emf);
         return factory;
    }
}

任何人都可以看到我在这里缺少的东西吗？

Answer 1

好的，经过更多搜索，我终于找到了解决这个问题的方法。我解决了这个问题，将这个方法添加到我的Dao课程中：

public Session getSessionFactory() {
    try {
        return sessionFactory.getCurrentSession();
    } catch (Exception e) {
        return sessionFactory.openSession();
    }
}

并更改通话：

sessionFactory.getCurrentSession()

的方法：

getSessionFactory()

<强>更新

我发现它的另一种解决方案

@Autowired
private EntityManagerFactory factory;

和

public EntityManager getEntityManager() {
    return factory.createEntityManager();
}

在我的dao类中，在每个方法中，使用以下内容：

@Transactional
public void insert(E object) {
    getEntityManager().persist(object);
}
