removeall重写equal
list<A> a list如果要调用remove（bo）,或者removeAll(a) 需要重写A 的equals方法,因为remove，removeAll方法时两个从左边移除与右边相等的对象，
那么在未重写equals方法的情况下，用默认的，默认的equals方法时比较两个对象的存储位置是否一致，以确定相等，这显然不符合业务需要，我们需要重写，让其
根据id等少数几个字段判断（有些方法会自动调用equals,然后根据equals返回的结果再执行相应的操作，比如list的removeAll，为了符合业务需要需要重写）
A Bean:类中
public class OpmUser implements Serializable {
public boolean equals(Object destination)
{
boolean retVal = false;
if ((destination != null) && (destination.getClass().equals(getClass())))
{
OpmUser bean = (OpmUser)destination;
if ((bean.getId() == null) && (getId() == null)) {
retVal = true;
} else if ((bean.getId() != null) && (bean.getId().equals(getId()))) {
retVal = true;
}
}
return retVal;
}
}
