hibernate @table

@javax.persistence.Table(catalog=”xx”,name=”xx”,schema=”xx”,uniqueConstraints={ @UniqueConstraint(columnNames={“xx”,”xx”})})
name:指定表的名称
catalog:指定数据库名称
schema:指定数据库的用户名
uniqueConstraints:指定唯一性字段约束,如为personid 和name 字段指定唯一性约束
uniqueConstraints={ @UniqueConstraint(name=”xxx” columnNames={“personid”, “name”})}
@UniqueConstraint 中的name=”xxx”为唯一约束名，代码如下:
