外来类的注入

11.1新建一外来类User的实体类;

packagecom.eduask.entity2;

publicclassUser3 {

privateintid;

privateString name;

privateString pwd;

publicintgetId() {

returnid;

}

publicvoidsetId(intid) {

this.id = id;

}

publicString getName() {

returnname;

}

publicvoidsetName(String name) {

this.name = name;

}

publicString getPwd() {

returnpwd;

}

publicvoidsetPwd(String pwd) {

this.pwd = pwd;

}

@Override

publicString toString() {

return"User3 [id=" + id + ", name=" + name + ", pwd=" + pwd + "]";

}

publicUser3(intid, String name, String pwd) {

super();

this.id = id;

this.name = name;

this.pwd = pwd;

}

publicUser3() {

super();

//TODOAuto-generated constructor stub

}

}

11.2新建一个Demo3的实体类;

packagecom.eduask.entity2;

publicclassDemo3 {

privateintid;

privateString name;

privateString pwd;

privateUser3 user3;

publicintgetId() {

returnid;

}

publicvoidsetId(intid) {

this.id = id;

}

publicString getName() {

returnname;

}

publicvoidsetName(String name) {

this.name = name;

}

publicString getPwd() {

returnpwd;

}

publicvoidsetPwd(String pwd) {

this.pwd = pwd;

}

publicUser3 getUser3() {

returnuser3;

}

publicvoidsetUser3(User3 user3) {

this.user3 = user3;

}

@Override

publicString toString() {

return"Demo3 [id=" + id + ", name=" + name + ", pwd=" + pwd + "]\n"+ user3 + "";

}

publicDemo3(intid, String name, String pwd, User3 user3) {

super();

this.id = id;

this.name = name;

this.pwd = pwd;

this.user3 = user3;

}

publicDemo3() {

super();

//TODOAuto-generated constructor stub

}

}

11.3新建一个TestDemo3的测试类;

packagecom.eduask.entity2;

importorg.springframework.context.support.ClassPathXmlApplicationContext;

publicclassTestDemo3 {

publicstaticvoidmain(String[] args) {

ClassPathXmlApplicationContext cx=newClassPathXmlApplicationContext("entity2Xml/demo3.xml");

Demo3 demo3=(Demo3) cx.getBean("demo3");

System.out.println(demo3);

}

}

11.4 新建一个demo3.xml的配置文件;

<?xml version="1.0"encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

">

<bean id="user3"class="com.eduask.entity2.User3"p:id="002"p:name="tom"p:pwd="123456"></bean>

<bean id="demo3"class="com.eduask.entity2.Demo3"p:id="001"p:name="link"p:pwd="123456"autowire=" byType"depends-on="user3"/>

</beans>

11.5 程序运行如下:

Demo3 [id=1, name=link, pwd=123456]
User3 [id=2, name=tom, pwd=123456]
