Java clone org.apache.commons.lang3.exception.CloneFailedException: Cloneable type com.itwenti.OrderOption has no clone method

问题：

OrderOption op2=ObjectUtils.clone(orderOption);//not work

1	OrderOption op2=ObjectUtils.clone(orderOption);//not work

org.apache.commons.lang3.exception.CloneFailedException: Cloneable type me.yek.shop.model.OrderOption has no clone method

解决：

实现interface Cloneable; 重载 Object.clone() 为 public Object clone()

class OrderOption implements Cloneable{
....

    @Override
    public OrderOption clone() throws CloneNotSupportedException {
        OrderOption ret=(OrderOption) super.clone(); 
...//ret.field1=field1;
        return ret;
    }
...
}

class OrderOption implements Cloneable{

....

@Override

public OrderOption clone() throws CloneNotSupportedException {

OrderOption ret=(OrderOption) super.clone();

...//ret.field1=field1;

return ret;

}

...

}
