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]
