我在query.list()行收到以下异常:
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,只有我得到它。提前致谢...
