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>
- 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
- 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
- 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- 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)
