Ⅷ.spring的点点滴滴--抽象对象和子对象

承接上文

抽象对象和子对象

.net篇（环境为vs2012+Spring.Core.dll v1.31）

    public class parent    {
        public string Name { get; set; }
        public int Age { get;set; }
    }
    public class chlid    {
        public string Name { get; set; }
        public int Age { get; set; }
    }
  <object id="p" type="SpringBase.parent,SpringBase">
    <property name="Name" value="cnljli-p0" />  
    <property name="Age" value="1" />
  </object>
  <object id="c" parent="p"  type="SpringBase.chlid,SpringBase">
    <property name="Age" value="2" />
  </object>
  <object id="p1">
    <property name="Name" value="cnljli-p1" />
    <property name="Age" value="2" />
  </object>
  <object id="c1" parent="p1"  type="SpringBase.chlid,SpringBase">
     <property name="Age" value="3" />
  </object>
  <object id="p2"  type="SpringBase.chlid,SpringBase" abstract="true">
    <property name="Name" value="cnljli-p2" />
    <property name="Age" value="3" />
  </object>
  <object id="c2" parent="p2"  type="SpringBase.chlid,SpringBase">
     <property name="Age" value="4" />
  </object>
  1. 可以在不声明一个类的情况下直接写一个Object来做模板

java篇（环境为Maven+Jdk1.7+IntelliJ IDEA 12.1.4）

package springdemo;
public class Parent {
    private String name;
    private Integer age;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Integer getAge() {
        return age;
    }
    public void setAge(Integer age) {
        this.age = age;
    }
}
class  Chlid{
    private String name;
    private Integer age;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Integer getAge() {
        return age;
    }
    public void setAge(Integer age) {
        this.age = age;
    }
}
    <bean id="p" class="springdemo.Parent">
        <property name="name" value="cnljli-p0" />
        <property name="age" value="1" />
    </bean>
    <bean id="c" parent="p"  class="springdemo.Chlid">
        <property name="age" value="2" />
    </bean>
    <bean id="p1"  class="springdemo.Parent" abstract="true">
        <property name="name" value="cnljli-p2" />
        <property name="age" value="3" />
    </bean>
    <bean id="c1" parent="p1"  class="springdemo.Chlid">
        <property name="age" value="4" />
    </bean>

java和Csharp的共同点

  1. 用其他类做父类,子类不一定继承父类,但是必须要包含父类的属性
  2. 可以用自己本身做为模板,当设置参数abstract为true的时候这个对象通过id调用的 时候返回会报错
  3. 子类会覆盖父类中某些属性的方法,不过不会覆盖属性为 depends-on(依赖)、dependency-check(依赖检查)、autowire(自动装配模式)、 singleton(单例)和lazy-init(延迟加载)
