[03] Spring "Hello World"

<dependencies>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>4.3.16.RELEASE</version>
    </dependency>
</dependencies>

 

2、建立一个简单的Java类 

public class Coder {
    private String name;
    private int age;
    public void print(){
        System.out.println("Hello World");
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
}

        Resource resource = rpt.getResource("/applicationContext.xml");
        BeanFactory bf = new XmlBeanFactory(resource);
        Coder coder = (Coder) bf.getBean("coder");
        coder.print();
    }
}

public class Test {
    public static void main(String[] args) {
        //ApplicationContext
        ApplicationContext ac = new ClassPathXmlApplicationContext("/applicationContext.xml");
        Coder coder = (Coder) ac.getBean("coder");
        coder.print();
    }
}
