java - 在单元测试中为 Hibernate 创建 JNDI 上下文

标签 java hibernate jdbc junit jndi

我有一个配置了 Hibernate 的项目:

<hibernate-configuration>
    <session-factory>
        <property name="hibernate.show_sql">true</property>
        <property name="hibernate.format_sql">true</property>
        <property name="jndi.url">jdbc/sqliteDB</property>
        <property name="hibernate.dialect">org.hibernate.dialect.SQLiteDialect</property>
        <property name="hibernate.connection.driver_class">org.sqlite.JDBC</property>
        <property name="hibernate.connection.release_mode">auto</property>
        <property name="current_session_context_class">thread</property>
        <property name="hibernate.connection.autoReconnect">true</property>
        <property name="hibernate.hbm2ddl.auto">update</property>
        <mapping class="com.web.models.SystemUsers"/>
    </session-factory>
</hibernate-configuration>

我想运行一些 JUnit 文件来测试数据库配置。我创建这个 Junit 文件:

@BeforeClass
    public static void setUp() throws Exception
    {
        try
        {
            // Create initial context
            System.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.apache.naming.java.javaURLContextFactory");
            System.setProperty(Context.URL_PKG_PREFIXES, "org.apache.naming");
            InitialContext ic = new InitialContext();

            ic.createSubcontext("java:");
            ic.createSubcontext("java:/comp");
            ic.createSubcontext("java:/comp/env");
            ic.createSubcontext("java:/comp/env/jdbc");

            SQLiteDataSource ds = new SQLiteDataSource();
            ds.setUrl("jdbc:sqlite:/C:/sqlite/test.sqlite");

            ic.bind("jdbc/sqliteDB", ds);
        }
        catch (NamingException ex)
        {
            Logger.getLogger(SQLiteDataSource.class.getName()).log(Level.SEVERE, null, ex);
        }

    }

但是当我运行它时，我收到此错误:

你知道我如何创建 JNDI 上下文以便 hibernate 可以使用它进行数据库查询吗？

更新。现在我收到此错误:

listUsersTest(com.net.server.UserProvisionTest)  Time elapsed: 0.001 sec  <<< ERROR!
java.lang.NoClassDefFoundError: Could not initialize class com.web.models.HibernateUtil

我使用这个 hibernate 工厂类:

public class HibernateUtil
{
    private static final SessionFactory sessionFactory;
    private static ServiceRegistry serviceRegistry;

    static
    {
        try
        {
            StandardServiceRegistry standardRegistry
                = new StandardServiceRegistryBuilder().configure("hibernate.cfg.xml").build();
            Metadata metaData
                = new MetadataSources(standardRegistry).getMetadataBuilder().build();
            sessionFactory = metaData.getSessionFactoryBuilder().build();
        }
        catch (Throwable th)
        {
            System.err.println("Enitial SessionFactory creation failed" + th);
            throw new ExceptionInInitializerError(th);
        }
    }

    public static SessionFactory getSessionFactory()
    {
        return sessionFactory;
    }
}

最佳答案

您尝试以错误的方式绑定(bind)。 而不是

ic.bind("jdbc/sqliteDB", ds);

这样做，

c.bind("java:/comp/env/jdbc/sqliteDB", ds);

您应该将其绑定(bind)(添加)到 java:/comp/env/jdbc，因为它是子上下文。

修复:第二个异常(exception) - 而不是:

<属性名称=“jndi.url”>jdbc/sqliteDB

添加此:

<属性名称=“hibernate.connection.datasource”>java:comp/env/jdbc/sqliteDB
