## Spring：给软件行业带来春天........   理念：整合现有技术使现有技术更加实用，本身是大杂烩   优点：   1、轻量级框架   2、ioc面向切面编程   3、对事务的支持   4、对框架的支持 ##

**Spring环境搭建：**

1、进入官网[https://spring.io/projects][https_spring.io_projects]

2、选择一个版本下载通常是选择最新

3、导入java工程

4、新建一个bean.xml文件

5、写入代码

新建一个hello.java类

package com.bean;
    
    public class Hello {
    
    	private String name;
    	
    	public Hello(String name) {
    		super();
    		this.name = name;
    	}
    
    	public void setName(String name) {
    		this.name = name;
    	}
    	
    	public void show(){
    		System.out.println("hello"+name);
    	}
    
    }

新建一个test.java类

package com.test;
    
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    import com.bean.Hello;
    import com.bean.User;
    
    public class Test {
    
    	public static void main(String[] args) {
    		// TODO Auto-generated method stub
    	   //解析beans.xml 
    		ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
    	    
    		Hello hello = (Hello)context.getBean("hello"); 
    		
    	    hello.show();
    	    
    	    
    	   
    	}
    
    }

在bean.xml文件配置属性

<?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 name="hello" class="com.bean.Hello">
    		<property name="name" value="Spring"></property>
    	</bean>   
    	
    	
    </beans>
