java之Spring简单使用

1、下载需要的jar包

a、首先下载Spring Framework http://www.springsource.org/spring-framework
b、下载common-loggin http://commons.apache.org/proper/commons-logging/download_logging.cgi
2、Spring中IOC的基本使用，在Eclipse中创建一个java项目

a、导入Spring相关的包以及common-loggin包(在项目上右键属性，java构建路径->库->添加外部jar(x))

b、创建Person类型

package springproject.demo;

public class Person {
private String mName;

public String getName() {
return mName;
}

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

c、创建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、创建Beans配置文件。在配置文件中通过控制反转创建Person对像。

<?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>

运行Main文件，就会输出xx文字了。
