In Java and other object oriented languages, a class is ablueprintor a template from which objects are created. Classes are defined by users as a template for definingdataandbehaviorof the objects that are created from that class. Classes are the basic building blocks of Object Oriented Program...
Classes that are derived from abstract classes use a concept called inheritance, which shares a set of attributes and methods. When done many times, this results in a hierarchy of classes where the abstract class is considered a root or base class. Abstract classes can be created in the follo...

parentBean 是 abstract 的,表示它不会被实例化,只作为模板使用。childBean 的 parent 属性指向 parentBean,表示它继承了 parentBean 的配置。 parentBean 有一个属性 commonProperty,值为 commonValue。childBean 有一个属性 specificProperty,值为 specificValue。在Spring解析这个配置文件,生成BeanDefinition的时候,...
An abstract class, in the context of Java, is a superclass that cannot be instantiated and is used to state or define general characteristics. An object cannot be formed from a Java abstract class; trying to instantiate an abstract class only produces a compiler error. The abstract class is...
