java之Spring簡單使用

1、下載需要的jar包

      a、首先下載Spring Framework http://www.springsource.org/spring-framework

      b、下載common-loggin http://commons.apache.org/proper/commons-logging/download_logging.cgi

2、Spring中IOC的基本使用，在Eclipse中創建一個java項目

a、導入Spring相關的包以及common-loggin包(在項目上右鍵屬性，java構建路徑->庫->添加外部jar(x))

b、創建Person類型

package springproject.demo;

public class Person {
	private String mName;

	public String getName() {
		return mName;
	}

	public void setName(String name) {
		mName = name;
	}
}

c、創建Main文件

package springproject.demo;

import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.FileSystemResource;
import org.springframework.core.io.Resource;

public class Main {
	public static void main(String[] args) {
		Resource resource = new FileSystemResource("bean.xml");
		BeanFactory factory = new XmlBeanFactory(resource);
		Person mybean = (Person) factory.getBean("person1");
		System.out.print(mybean.getName());
	}
}

 

d、創建Beans配置文件。在配置文件中通過控制反轉創建Person對像。

<?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="person1" class="springproject.demo.Person">
    <property name="name" value="xx"></property>
</bean>

</beans>

運行Main文件，就會輸出xx文字了。
