spring--Autowired setter 方法

复制提示
在Spring中，可以使用 @Autowired 注解通过setter方法，构造函数或字段自动装配Bean。此外，它可以在一个特定的bean属性自动装配。
注 @Autowired注解是通过匹配数据类型自动装配Bean。
package Autowired;/**

public class person1 {
public String getName() {
return name;
} public void setName(String name) {
this.name = name;
} public String getAdress() {
return adress;
} public void setAdress(String adress) {
this.adress = adress;
} public int getAge() {
return age;
} public void setAge(int age) {
this.age = age;
} private String name;
private String adress;
private int age;}

通过构造方法注入：
package Autowired;import org.springframework.beans.factory.annotation.Autowired;/**
* Created by luozhitao on 2017/8/9.
*/
public class Customer2 {
public int getType() {
return type;
} public void setType(int type) {
this.type = type;
} public String getAction() {
return action;
} public void setAction(String action) {
this.action = action;
} public person1 getPerson() {
return person;
} public void setPerson(person1 person) {
this.person = person;
} private int type;
private String action;
private person1 person; @Autowired
public Customer2(person1 person){ this.person=person;
}}
通过字段进行注入：
package Autowired;import org.springframework.beans.factory.annotation.Autowired;/**
* Created by luozhitao on 2017/8/9.
*/
public class Customer3 { public int getType() {
return type;
} public void setType(int type) {
this.type = type;
} public String getAction() {
return action;
} public void setAction(String action) {
this.action = action;
} public person1 getPerson() {
return person;
} private int type;
private String action;
@Autowired
private person1 person;}
