新建UserDao 类：

package org.xxx.Dao;

import org.springframework.stereotype.Repository;

@Repository
public class UserDao {

    public void test(){
        System.out.println("UserDao Test ...");
    }
}

新建UserService类

package org.xxx.Service;

import org.springframework.stereotype.Service;
import org.xxx.Dao.UserDao;

import javax.annotation.Resource;

@Service
public class UserService {

    @Resource
    private UserDao userDao;

    public void test(){
        System.out.println("UserDao输出测试...");
        this.userDao.test();
        System.out.println("UserService输出测试...");
        System.out.println("UserService Test...");
    }
}

新建配置类IocConfig:

package org.xxx.Config;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration
@ComponentScan("org.xxx")
public class IocConfig {
}

新建测试类，测试：

package org.xxx;

import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.xxx.Config.IocConfig;
import org.xxx.Service.UserService;

public class Starter {
    public static void main(String[] args) {

        AnnotationConfigApplicationContext applicationContext = new AnnotationConfigApplicationContext(
                IocConfig.class
        );
        UserService userService = applicationContext.getBean(UserService.class);
        userService.test();
    }
}

测试输出结果：
