我在 query.list（） 行中收到以下异常：

org.hibernate.MappingException: No Dialect mapping for JDBC type: -4

以下是我的配置文件：

<property name="hibernate.connection.driver_resource">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.password">mysql</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/mydatabase</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.default_schema">mydatabase</property>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>

当我尝试在Eclipse IDE中运行应用程序时，不会出现此异常，但是当我创建应用程序jar并运行时，只有我得到了它。提前致谢…
