通过xml文件向Spring容器注册组件

创建一个maven工程，导入依赖

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>4.1.3.RELEASE</version>
</dependency>

项目目录结构：

新建类Person和beans.xml文件

@Data
@NoArgsConstructor
@AllArgsConstructor
public class Person {
    private String name;
    private Integer age;
}

<?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="person" class="com.example.bean.Person">
        <property name="name" value="tom"/>
        <property name="age" value="20"/>
    </bean>

</beans>

运行测试

public static void main(String[] args) {

    ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("beans.xml");
    Object person = applicationContext.getBean("person");
    System.out.println(person);
}

控制台打印结果
