构造方法数据类型的测试

9.1 新建一个Demo1的实体类

package com.eduask.entity2;

//新建一个Demo1的实体类;

public class Demo1 {

private int id;

private String name;

private String pwd;

public Demo1() {

}

public int getId() {

return id;

}

public void setId(int id) {

this.id = id;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getPwd() {

return pwd;

}

public void setPwd(String pwd) {

this.pwd = pwd;

}

@Override

public String toString() {

return "Demo1 [id=" + id + ", name=" + name + ", pwd=" + pwd + "]";

}

public Demo1(int id, String name, String pwd) {

super();

this.id = id;

this.name = name;

this.pwd = pwd;

}

}

9.2 新建一个TestDemo1的测试类

package com.eduask.entity2;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestDemo1 {

public static void main(String[] args) {

ClassPathXmlApplicationContext cx=new ClassPathXmlApplicationContext("entity2Xml/demo1.xml");

Demo1 demo1=(Demo1) cx.getBean("Demo1");

System.out.println("构造方法类型的测试");

System.out.println(demo1);

}

}

9.3新建一个Demo1.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"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans.xsd"

>

<bean id="Demo1" class="com.eduask.entity2.Demo1">

<constructor-arg name="id" value="001" index="0" type="int"/>

<constructor-arg name="name" value="tom" index="1" type="String"/>

<constructor-arg name="pwd" value="123456" index="2" type="String"/>

</bean>

</beans>

9.4程序运行如下:

构造方法类型的测试
Demo1 [id=1, name=tom, pwd=123456]
