[置顶] Setter Injection

在bean中通过提供属性的setter方法,在Spring配置文件中进行注入。实现了一定的松耦合。


步骤一:新建Java工程-SpringDemo。

步骤二:导入Spring JAR包和commons-logging JAR包。

步骤三:编写bean

 

public class Animal {

	private String category;
	private String name;
	private int age;

	public String getCategory() {
		return category;
	}

	public String getName() {
		return name;
	}

	public int getAge() {
		return age;
	}

	@Override
	public String toString() {
		return "Animal [category=" + category + ", name=" + name + ", age="
				+ age + "]";
	}

}


步骤四:编写Spring配置文件(位于src目录下)

 

 

<?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="panda" class="cn.zj.hz.Animal" >
	    <property name="category" value="Mammal" />
	    <property name="name"     value="panpan"  />
	    <property name="age"      value="3" />
	</bean>

</beans>


步骤五:编写测试类:

 

 

public class App {

	public static void main(String[] args) {
		ApplicationContext context = new ClassPathXmlApplicationContext("SpringConfig.xml");
		Animal panda = (Animal) context.getBean("panda");
		System.out.println(panda);
	}
}


步骤六:运行,查看结果:

 

 

Animal [category=Mammal, name=panpan, age=3]

 

项目结构:
