一.构造器实例化
One.class类：
public class One {
public void say(){
System.out.println("我是构造器实例化");
}
}
applicationContext.xml:
<?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-4.3.xsd"> <bean id="one" class="cn.chauncey.ioc.One"/> </beans>
Test.class测试类：
public class OneTest { public static void main(String[] args) { ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml"); One one = (One) applicationContext.getBean("one"); one.say(); } }
运行结果：
