Bean装配--xml

1，bean

package com.songyan.zhangpei;

import java.util.ArrayList;

import com.sun.xml.internal.bind.v2.schemagen.xmlschema.List;

public class User {
    private String userName;
    private String password;
    private ArrayList<String> list;
    @Override
    public String toString() {
        String string="[usernname: "+userName+"  password: "+password+"  list: "+list+"]";
        return string;
    }
    public User(){}
    public User(String username,String password,ArrayList<String> list)
    {
        this.userName=username;
        this.password=password;
        this.list=list;
    }
    public String getUserName() {
        return userName;
    }
    public void setUserName(String userName) {
        this.userName = userName;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public ArrayList<String> getList() {
        return list;
    }
    public void setList(ArrayList<String> list) {
        this.list = list;
    }

}

2， xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd">

<bean id="user1" class="com.songyan.zhangpei.User">
<property name="userName" value="zhangsan"></property>
<property name="password" value="123"></property>
<property name="list">
<list>
    <value>list1</value>
    <value>list2</value>
    <value>list3</value>
</list>
</property>
</bean>

<bean id="user2" class="com.songyan.zhangpei.User">
<constructor-arg index="0" value="lisi"></constructor-arg>
<constructor-arg index="1" value="12345"></constructor-arg>
<constructor-arg index="2" >
<list>
    <value>list1</value>
    <value>list2</value>
    <value>list3</value>
</list></constructor-arg>
</bean>
</beans>

3， 测试

package com.songyan.zhangpei;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test {
public static void main(String[] args) {
    ApplicationContext applicationContext= new ClassPathXmlApplicationContext("com/songyan/zhangpei/beanszp.xml");
    User user1=(User)applicationContext.getBean("user1");
    User user2=(User)applicationContext.getBean("user2");
    System.out.println(user1.toString());
    System.out.println(user2.toString());
}
}

4， 运行结果

user1使用的是bean装配的设值注入

user2 使用的是bean的构造器注入
