Spring之注解注入bean

1.引入jar包。配置log4j.properties文件

2.创建Person类

  1 package com.hy.spring.pojo;
  2 
  3 import org.springframework.stereotype.Component;
  4 
  5 //使用component的注解方式注入
  6 //@Component("person"),等同于使用依赖注入方式，配置的<bean name="person"  class="com.hy.spring.pojo.Person"></bean>
  7 @Component("person")
  8 public class Person {
  9 
 10 	@Override
 11 	public String toString() {
 12 		return "Person [name=" + name + ", age=" + age + ", mycar=" + mycar + "]";
 13 	}
 14 
 15 	private String name;
 16 	private Integer age;
 17 	private Car mycar;
 18 
 19 	public  Person() {
 20 		super();
 21 		System.out.println("构造方法被调用");
 22 	}
 23 
 24 	public String getName() {
 25 		return name;
 26 	}
 27 
 28 	public void setName(String name) {
 29 		this.name = name;
 30 	}
 31 
 32 	public Integer getAge() {
 33 		return age;
 34 	}
 35 
 36 	public void setAge(Integer age) {
 37 		this.age = age;
 38 	}
 39 
 40 	public Car getMycar() {
 41 		return mycar;
 42 	}
 43 
 44 	public void setMycar(Car mycar) {
 45 		this.mycar = mycar;
 46 	}
 47 }
