为了识别po对象中，通常都会用po对象继承一个BaseObject基类，小弟也是如此做法，基类是从网上找到的一个比较好的范例。
public
?
class
?BaseObject?
implements
?Serializable?
{
????
private
?
static
?
final
?
long
?serialVersionUID?
=
?
-
1540986753080346874L
;
????
public
?String?toString()?
????{
????????
return
?ToStringBuilder.reflectionToString(
this
,?ToStringStyle.MULTI_LINE_STYLE);
????}
????
????
public
?
boolean
?equals(Object?o)?
????{
????????
return
?EqualsBuilder.reflectionEquals(
this
,?o);
????}
????
????
public
?
int
?hashCode()?
????{
????????
return
?HashCodeBuilder.reflectionHashCode(
this
);
????}
}cs
