spring注入成员对象
就是将对象注入到另外一个对象中。这个例子就是有一个学校类,学校类中有一个校长类,最后使用测试文件输出学校类中的信息。
代码结构
学校类
package com.test.SpringGetSet; public class School { private Present present; public Present getPresent() { return present; } public void setPresent(Present present) { this.present = present; } public String getShoolName() { return shoolName; } public void setShoolName(String shoolName) { this.shoolName = shoolName; } String shoolName; public void say() { System.out.println("校名:"+shoolName); System.out.println("校长姓名:"+present.getName()); } }
校长类
package com.test.SpringGetSet; public class Present { private String name; 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; } private int age; }
beans.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans> <bean id="present" class="com.test.SpringGetSet.Present"> <property name="name" value="杨发癫" /> <property name="age" value="40" /> </bean> <bean id="school" class="com.test.SpringGetSet.School"> <property name="shoolName" value="上饶县中" /> <property name="present"> <ref bean="present"/> </property> </bean> </beans>
package com.test.SpringGetSet; import org.springframework.beans.factory.BeanFactory; import org.springframework.beans.factory.xml.XmlBeanFactory; import org.springframework.core.io.ClassPathResource; import SpringByHand.Hello; public class SetDemo001 { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub BeanFactory factory=new XmlBeanFactory(new ClassPathResource("com/test/SpringGetSet/beans.xml")); School s=(School) factory.getBean("school"); s.say(); } }
输出结果
