Spring-01

1）下载spring 和common.logging日志包

2）新建javaproject项目,新建lib目录

3)将spring lib下的spring-beans-4.1.3.BUILD-SNAPSHOT.jar

spring-context-4.1.3.BUILD-SNAPSHOT.jar

spring-core-4.1.3.BUILD-SNAPSHOT.jar

spring-expression-4.1.3.BUILD-SNAPSHOT.jar

和commons-logging-1.2.jar

引入，进行buildpath，加入引用库

4）创建helloWorld文件，

public class HelloWorld {

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

}

5）在src下创建applicationContext.xml，设置beans

<?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="helloworld" class="com.yc.spring.beans.HelloWorld">

    <property name="name" value="Spring"></property>

  </bean>

</beans>

6）在测试类下

  1.构造ioc容器

ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext.xml");

  2.获取bean对象

ctx.getBean("helloworld");

3.调用方法
