问题描述
我正在实现AbstractFactory模式,允许外部人员创建工厂。我正在从属性文件中读取工厂实现名称,加载工厂类并使用它来构造对象。问题是,当我尝试创建任务的对象时,在工厂实现中的某个地方出现以下错误:
I am implementing the AbstractFactory pattern allowing outsiders to create Factories. I am reading the factory implementation name from a properties file, loading the factory class and using it to construct objects. Problem is that somewhere in my factory implementation when I'm trying to create an object of a task I get the following error:
下面是GetUrl构造函数,没什么好看的!
Following is the GetUrl constructor, nothing fancy!
public GetUrl( String protocol, String port, String hostname, String path, String producerClassName ) {
super(producerClassName);
this.protocol = protocol;
this.hostname = hostname;
this.port = port;
this.path = path;
}
这里有什么反馈吗?交叉发布

推荐答案
我使用的类的版本不匹配。现在可以使用。
There was some mismatch in the version of classes i was using. It works now.
