同事们，我有HibernateUtil.class，它返回sessionFactory：

public class HibernateUtil {
    private static final Logger LOG = Logger.getLogger(HibernateUtil.class.getName());
    private static final SessionFactory sessionFactory;

    static {
        try {
            // Create the SessionFactory from app.properties

            java.util.Properties properties = new Properties();
            properties.load(new FileInputStream("src//main//resources//app.properties"));
            Configuration configuration = new Configuration();

            configuration.configure("hibernate.cfg.xml").addProperties(properties);;

            ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder()
                    .applySettings(configuration.getProperties()).build();

            sessionFactory = new Configuration().configure().buildSessionFactory(serviceRegistry);


        } catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            LOG.info("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

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

app.properties中有属性：

hibernate.connection.url=jdbc:oracle:thin:@srv.te.loc:1521:DB
hibernate.connection.driver_class=oracle.jdbc.driver.OracleDriver
hibernate.connection.username=user
hibernate.connection.password=pass
hibernate.dialect=org.hibernate.dialect.Oracle10gDialect
hibernate.current_session_context_class=thread

当我打电话给测试IDE节目时：

如果我在标准hibernate.cfg.xml中使用相同的属性（url，pass，dialect）并从serviceRegistry中的new Configuration().configure().buildSessionFactory(serviceRegistry)中删除HibernateUtil.class，则相同的测试工作正常。

我的属性文件或HibernateUtil类有什么问题？

hibernate.cfg.xml也是如此：

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



    <property name="connection.pool_size">10</property>
    <property name="hibernate.default_schema">defschema</property>
    <property name="show_sql">false</property>
    <property name="hibernate.connection.autocommit">false</property>

    <mapping class="com.comp.db.entity.Applications"/>
    <mapping resource="hbconfig/Applications.hbm.xml"></mapping>


  </session-factory>
</hibernate-configuration>

2 个答案:

答案 0 :(得分：2)

我认为问题在于：

<key>LSMinimumSystemVersion</key>
<string>10.7.0</string>

为什么要实例化一个新的配置，而不是重用上面几行初始化的旧配置？

更改为

sessionFactory = new Configuration()...

修改

只需将属性添加到配置中，而不是使用ServiceRegistry，如下所示：

sessionFactory = configuration.configure().buildSessionFactory(serviceRegistry);

这对我有用。只需进行调试即可确保在加载后正确填充属性。

答案 1 :(得分：0)

首先，你的配置方式Hibernate 5是不正确的。有关详细信息，请参阅https://stackoverflow.com/a/32711654/3405171。

使用属性文件的绝对路径进行非标准属性的配置，可以执行此操作

File propertiesPath = new File("some_path");
ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().
    configure().loadProperties(propertiesPath).build();
SessionFactory sf = new Configuration().buildSessionFactory(serviceRegistry);

请参阅属性作为资源。

ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().
    configure().loadProperties("app.properties").build();
SessionFactory sf = new Configuration().buildSessionFactory(serviceRegistry);

您需要在类路径中使用app.properties。
