spring 初学程序

spring 的配置文件如下

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd">


<beans > 	
    

   <bean id="helloBean" class="com.czg.bean.HelloBean" autowire="byType">
   	<property name="hello">
   		<value>hello!tom</value>
   	</property>
   </bean>
	<bean id="date" class="java.util.Date"></bean>
</beans>



HelloBean.java 的代码
[code=java"]

import java.util.Date;

public class HelloBean {
	private String Hello;
	private Date date;
	public String getHello() {
		return Hello;
	}
	public void setHello(String hello) {
		Hello = hello;
	}
	public Date getDate() {
		return date;
	}
	public void setDate(Date date) {
		this.date = date;
	}
	
	

}

测试代码

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

public class SpringDemo {
	public static void main(String[] args) {
		ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
		HelloBean helloBean = (HelloBean)context.getBean("helloBean");
		System.out.println(helloBean.getDate());
	}

}
