测试Spring的service层
Account实体类

package cn.zut.bigdata.domain;

import java.io.Serializable;

public class Account implements Serializable {

    private Integer id;
    private String name;
    private Double money;

    public Integer getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

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

    public Double getMoney() {
        return money;
    }

    public void setMoney(Double money) {
        this.money = money;
    }

    @Override
    public String toString() {
        return "Account{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", money=" + money +
                '}';
    }
}

AccountService 接口类

package cn.zut.bigdata.service;

import cn.zut.bigdata.domain.Account;

import java.util.List;

public interface AccountService {

    // 查询所有账户
    public List<Account> findAll();
    // 保存账户信息
    public void saveAccount(Account account);

}

接口实现类

package cn.zut.bigdata.service.impl;

import cn.zut.bigdata.domain.Account;
import cn.zut.bigdata.service.AccountService;
import org.springframework.stereotype.Service;

import java.util.List;

@Service("accountService")
public class AccountServiceImpl implements AccountService {


    @Override
    public List<Account> findAll() {
        System.out.println("业务层：查询所有账户信息");
        return null;
    }

    @Override
    public void saveAccount(Account account) {
        System.out.println("业务层：保存账户信息");

    }
}

测试代码

package cn.zut.bigdata.mytest;

import cn.zut.bigdata.dao.AccountDao;
import cn.zut.bigdata.domain.Account;
import cn.zut.bigdata.service.AccountService;

import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.core.io.Resource;

import java.io.IOException;
import java.io.InputStream;
import java.util.List;

public class TestSpring {

    @Test
    public void run1(){

        // 加载配置文件
        ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
        // 获取对象
        AccountService as = (AccountService) ac.getBean("accountService");
        // 调用方法
        as.findAll();
    }
}

AccountDao接口类

package cn.zut.bigdata.dao;

import cn.zut.bigdata.domain.Account;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;

import java.util.List;

    public List<Account> findAll();
    // 保存账户信息
    @Insert("insert into account(name,money) values(#{name},#{money})")
    public void saveAccount(Account account);
}

测试类
