UnknownUnwrapTypeException：无法解包到请求的类型[javax.sql.DataSource]

Question

我知道此问题之前已经得到解答，但是没有一个回复似乎对我有帮助，因为我没有在我的项目中使用数据源。

我有一个与Spring和Hibernate集成的Maven项目，连接到SQL Server 2014数据库。

这是我的pom.xml，您可以在其中看到版本：

这是hibernate.cfg.xml：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

        <property name="current_session_context_class">thread</property>
    </session-factory>
</hibernate-configuration>

我创建会话工厂的类：

@Configuration
@EnableTransactionManagement
@EnableWebSecurity
@EnableGlobalMethodSecurity
@Import({ SecurityConfig.class })
public class HibernateUtils { 

    @Autowired
    @Qualifier("sessionFactory")
    private static SessionFactory sessionFactory = buildSessionFactory();   

    @Bean
    private static SessionFactory buildSessionFactory() {
        try {
            if (sessionFactory == null) {
                org.hibernate.cfg.Configuration configuration = new org.hibernate.cfg.Configuration().configure("/hibernate.cfg.xml");
                addAnnotatedClasses(configuration);             
                ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().applySettings(
                        configuration.getProperties()).build();

                sessionFactory = new org.hibernate.cfg.Configuration().configure().buildSessionFactory(serviceRegistry);
            }
            return sessionFactory;
        } catch (Throwable ex) {
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    @Bean
    @Autowired
    public HibernateTransactionManager transactionManager(SessionFactory sessionFactory) {
        System.out.println("enter transactionManager");
        HibernateTransactionManager txManager = new org.springframework.orm.hibernate5.HibernateTransactionManager();
        txManager.setSessionFactory(sessionFactory);

        return txManager;
    }

我使用Tomcat 8.每当我运行它时，我得到UnknownUnwrapTypeException：无法解包到请求的类型[javax.sql.DataSource]

我已经尝试添加c3p0连接池的详细信息，正如我在之前的帖子中看到的那样，我不再收到错误，但服务器也没有启动，只是在创建池后挂起。

请有人帮忙吗？

Answer 1

好吧，我已经弄明白了。似乎，而不是我当前的sessionFactory创建，我应该有类似的东西：

StandardServiceRegistryBuilder  serviceRegistryBuilder = new StandardServiceRegistryBuilder();  
                DataSource datasource = getDataSource();
                serviceRegistryBuilder.applySetting(Environment.DATASOURCE, datasource);
                serviceRegistryBuilder.applySettings(configuration.getProperties());
                Properties hibernateProperties = setHibernateProperties();
                serviceRegistryBuilder.applySettings(hibernateProperties);
                StandardServiceRegistry serviceRegistry = serviceRegistryBuilder.build();

                sessionFactory = configuration.buildSessionFactory(serviceRegistry); 

这意味着我将hibernate.cfg.xml中的属性外化为：

@Bean
public static DataSource getDataSource() {
    BasicDataSource dataSource = new BasicDataSource();
    dataSource.setDriverClassName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
    dataSource.setUrl("jdbc:sqlserver://localhost:1433;databaseName=Licenta");
    dataSource.setUsername("sa");
    dataSource.setPassword("admin9");
    return dataSource;
}

 private static Properties setHibernateProperties() {
     Properties properties = new Properties();
     properties.put("hibernate.dialect", "org.hibernate.dialect.SQLServer2008Dialect");
     properties.put("hibernate.hbm2ddl.auto", "create");
     properties.put("hibernate.show_sql", "true");
     return properties;        
}
