SpringAop

springAop原理代理模式 1：Target

註解的種類： @resource(爲成員變量注入值）

@compant @service @respority @controller 四個特性是同樣的

<context:component-scan base-package="com.shuiming"></context:component-scan> 做用1:掃描全部的bean 等價於<bean id="xxxx" class="xxxxxx"> 2:爲全部的Bean的成員變量注入值. @Component(value="clinic") public class Clinic { private String name; private int age; public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; }

}
