User.java
package cn.com.xf; public class User { private String name; private int age; private String remark; //省略setter/getter方法 @Override public String toString() { return "User [name=" + name + ", age=" + age + ", remark=" + remark + "]"; } }
UserUtil.java
package cn.com.xf; //注意引入此包 import org.springframework.beans.factory.annotation.Autowired; public class UserUtil { @Autowired //自动装配 private User user; public User getUser() { return user; } public void setUser(User user) { this.user = user; } public boolean isUser() { if (user != null) { return true; } else { return false; } } }
Spring.xml配置文件

以上已经实现了自动装配功能,本节已对注解有了初步认识,后面我们将对注解进行全面的学习。
本节的测试类与前几节一样,后面的内容,我们重新定义类,老是User,大家都烦了吧!!!
