Hibernate Dialect.数据库方言问题

1.改造默认方言设置，继承特定数据库的方言基类

package selleck.util;import java.sql.Types;import org.hibernate.Hibernate;   import org.hibernate.dialect.MySQL5Dialect;public class MySQL5Dialects extends MySQL5Dialect{public MySQL5Dialects() {super();registerHibernateType(Types.DECIMAL, Hibernate.BIG_DECIMAL.getName());                   registerHibernateType(-1, Hibernate.STRING.getName());}}

2.修改Hibernate方言默认配置文件

hibernate.dialect= selleck.util.MySQL5Dialects
