          spring-aspects-4.1.6.RELEASE.jar
          spring-beans-4.1.6.RELEASE.jar

             编写spring配置文件(名称可以自定义)

    (废话少说-----:)

    Hello.java

    package com.yikuan.cn;

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

    beans.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就是java对象,由spring容器来创建和管理 -->
    <bean name="hello" class="com.yikuan.cn.Hello">
    <property name="name" value="张三"/>
    </bean>
    </beans>

    Test1.java

    package com.yikuan.cn.test;

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

    import com.yikuan.cn.Hello;

    public class Test1 {
    public static void main(String[] args) {
    //解析beans.xml文件,生成管理相应的bean对象
    ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
    Hello hello = (Hello) context.getBean("hello");
    hello.show();
    }
    }
