Spring通过注解装配Bean

 

 

 

通过注解实现ServiceImpl业务

一、使用@Component装配Bean

1、 定义类：User

在类上面加@Component注解，在属性上面加@Value值

package com.wbg.springxmlbean.entity;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component(value = "user")
public class User {
    @Value("2")
    private int id;
    @Value("韦邦杠")
    private String name;
    @Value("18")
    private int age;
    private Role role;

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", role=" + role +
                ", name='" + name + '\'' +
                ", age=" + age +
                '}';
    }

    public Role getRole() {
        return role;
    }

    public void setRole(Role role) {
        this.role = role;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

}
