spring 自动装配Date为null
一次奇怪的事情,在为以下类实行自动装配时不成功:
public class Computer { private Date date; public Date getDate() { return date; } public void setDate(Date date) { this.date = date; } }
xml配置为:
<bean id="date" class="java.util.Date"> </bean> <bean id="computer" class="com.zlc.test.Computer" autowire="byName"> </bean>
运行以下代码:
public static void main(String[] args) { String conf = "applicationContext.xml"; //创建容器对象 AbstractApplicationContext ac = new ClassPathXmlApplicationContext(conf); Computer c = ac.getBean("computer",Computer.class); System.out.println(c.getDate()); }
输出:
改为autowire="byType",运行结果也是一样的
