Spring with Hibernate - 找到预绑定的 JDBC 连接

[英]Spring with Hibernate - Pre-bound JDBC Connection found

问题描述

Faced weird problem with "Pre-bound JDBC Connection found" in Spring (5.1.7.RELEASE) and Hibernate (5.4.10.Final).在 Spring (5.1.7.RELEASE) 和 Hibernate (5.4.10.Final) 中遇到了“Pre-bound JDBC Connection found”的奇怪问题。 I've read related questions and need to say that I have only 1 datasource and only 1 transaction manager in my code.我已阅读相关问题，需要说明的是，我的代码中只有 1 个数据源和 1 个事务管理器。 App is running on Wildfly 18.0.1.应用程序在 Wildfly 18.0.1 上运行。

So here's my hibernate config:所以这是我的休眠配置：

@Bean
public LocalSessionFactoryBean sessionFactory() throws NamingException {
    LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
    sessionFactory.setDataSource(dataSource());
    sessionFactory.setPackagesToScan(new String[] { "com.mycompany"});
    sessionFactory.setHibernateProperties(hibernateProperties());
    return sessionFactory;
}

@Bean
public DataSource dataSource() throws NamingException {
    return (DataSource) new JndiTemplate().lookup(env.getProperty("jndi.jdbc.AGSQL"));
}

@Bean(name = "transactionManager")
public HibernateTransactionManager transactionManager(SessionFactory sessionFactory) {
    HibernateTransactionManager txManager = new HibernateTransactionManager();
    txManager.setSessionFactory(sessionFactory);
    return txManager;
}

private Properties hibernateProperties() {
    return new Properties() {
        {
            setProperty("hibernate.dialect", env.getProperty("hibernate.dialect"));
            setProperty("show_sql", env.getProperty("show_sql"));
            setProperty("hibernate.connection.isolation", String.valueOf(Connection.TRANSACTION_READ_UNCOMMITTED));
        }
    };
}

Datasource is configured via jndi.数据源是通过 jndi 配置的。 And when I try to open any page it throws error:当我尝试打开任何页面时，它会引发错误：

18:39:28,457 ERROR [io.undertow.request] (default task-30) UT005023: Exception handling request to /AGService/map: org.springframework.transaction.IllegalTransactionStateException: Pre-bound JDBC Connection found! HibernateTransactionManager does not support running within DataSourceTransactionManager if told to manage the DataSource itself. It is recommended to use a single HibernateTransactionManager for all transactions on a single DataSource, no matter whether Hibernate or JDBC access.

It's UserDao class:这是 UserDao 类：

@Repository
public class UserDao extends AbstractDao<Long, UserEntity> {

    public UserDao() {
        super(UserEntity.class);
    }

    /**
     * Get user by login
     * @param login String
     * @return User object
     */
    @Transactional("transactionManager")
    public User getByLogin(String login) {
        Session session = getSession();
        User user = null;
        try {
            UserEntity userEntity = (UserEntity)session
                    .createQuery("FROM UserEntity WHERE login = :login")
                    .setParameter("login", login).uniqueResult();
            user = new User(userEntity);

            RoleEntity roleEntity = (RoleEntity)session
                                        .createQuery("FROM RoleEntity WHERE id = :id")
                                        .setParameter("id", user.getRoleId())
                                        .uniqueResult();
            user.setRole(roleEntity);

        } catch (HibernateException e) {
            e.printStackTrace();
        }
        return user;
    }
}

So...I have only one datasource, but have this exception... And that's not all.所以......我只有一个数据源，但有这个例外......这还不是全部。 If I change data source to this, my app works properly without any exceptions:如果我将数据源更改为此，我的应用程序可以正常工作，没有任何异常：

@Bean
public DataSource dataSource() throws NamingException {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName(env.getProperty("hibernate.connection.driver_class"));
    dataSource.setUrl(env.getProperty("hibernate.connection.url"));
    dataSource.setUsername(env.getProperty("hibernate.connection.username"));
    dataSource.setPassword(env.getProperty("hibernate.connection.password"));
    return dataSource;
}

I think that Wildfly can manage it's own transactions with it's own datasources, but I didn't find any settings for transactions on Wildfly config.我认为 Wildfly 可以使用自己的数据源管理自己的事务，但我没有在 Wildfly 配置上找到任何事务设置。 And anyway I need to have a transactionmanager bean to link from @Transactional.无论如何，我需要有一个事务管理器 bean 来从@Transactional 进行链接。

I'm stuck on it, any help appreciated.我坚持下去，任何帮助表示赞赏。

Changed transaction manager to this and now it works as expected:将事务管理器更改为此，现在它按预期工作：

@Bean(name = "transactionManager")
public PlatformTransactionManager transactionManager(SessionFactory sessionFactory) {
    JpaTransactionManager transactionManager = new JpaTransactionManager();
    transactionManager.setEntityManagerFactory(sessionFactory);
    return transactionManager;
}

But what's the inner differences between these two implementations?但是这两种实现之间的内部差异是什么？
