Oracle 数据库:
Hibernate annotation :
@Column(name="NUMBERS",columnDefinition="NUMBER(20,3) default 0 ")
public BigDecimal getNumbers() {
return numbers;
}
异常:
Caused by: org.hibernate.HibernateException: Wrong column type: NUMBERS, expected: NUMBER(20,3) default 0
at org.hibernate.mapping.Table.validateColumns(Table.java:261)

解决方法:
@Column(name="NUMBERS",columnDefinition="number(20,3) default 0 ")
public BigDecimal getNumbers() {
return numbers;
}
原因:hibernate 在列定义选项中,数据库中的所有类型应为小写number. hibernate在此直接面对数据库,所以区分大小写.
