第一步： 編寫實體類

Dog.java

package com.xuzhiwen.spring7;

public class Dog {
    private String name;
    private String hobby;
    
    public void setName(String name) {
        this.name = name;
    }
    
    public void setHobby(String hobby) {
        this.hobby = hobby;
    }

    @Override
    public
 
 String toString() {
        return "Dog [name=" + name + ", hobby=" + hobby + "]";
    }
}

第二步：編寫配置文件

applicationContext6.xml

<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-3.0.xsd"
 
>
    
    <bean id="dog" class="com.xuzhiwen.spring7.Dog">
        <property name="name" value="dahuang" />
        <property name="hobby" value="eat food" />
    </bean>
</beans>

第三步：編寫測試類

package com.xuzhiwen.spring7;

import org.springframework.context.ApplicationContext;
 
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test {
    public static void main(String[] args) {
        ApplicationContext app = new ClassPathXmlApplicationContext("applicationContext6.xml");
        Dog dog = (Dog) app.getBean("dog");
        System.out.println(dog);
    }
}

第四步：運行結果如下

spring setter註入
