1、在eclipse中安装spring的开发工具

2、新建一个maven项目

3、添加五个最基本的依赖

<!-- spring 容器包 -->																															
	<dependency>																														
      <groupId>org.springframework</groupId>																															
      <artifactId>spring-context</artifactId>																															
      <version>4.3.14.RELEASE</version>																															
    </dependency>																															
    <dependency>																															
      <groupId>org.springframework</groupId>																															
      <artifactId>spring-context-support</artifactId>																															
      <version>4.3.14.RELEASE</version>																															
    </dependency>																															
    <!-- spring 核心包 -->																															
    <dependency>																															
      <groupId>org.springframework</groupId>																															
      <artifactId>spring-core</artifactId>																															
      <version>4.3.14.RELEASE</version>																															
    </dependency>																															
	<!-- spring bean -->																														
    <dependency>																															
      <groupId>org.springframework</groupId>																															
      <artifactId>spring-beans</artifactId>																															
      <version>4.3.14.RELEASE</version>																															
    </dependency>																															
    <!-- spring 一些表示式 -->																															
    <dependency>																															
      <groupId>org.springframework</groupId>																															
      <artifactId>spring-expression</artifactId>																															
      <version>4.3.14.RELEASE</version>																															
    </dependency>

4、新建一个实体类user

User.java

public class User {
	private String name;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}
	
}

5、新建一个spring的配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">

	<bean id="user" class="com.test.testspring.User"></bean>
	

</beans>

6、编写测试类

public class Test {

	public static void main(String[] args) {
		ClassPathXmlApplicationContext context 
		= new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
		User user = (User) context.getBean("user");
		System.out.println(user);
	}

}
