基于注解的mybatis整合spring开发流程？

废话不多说，卷起袖子直接干。
（1）先上一张项目结构图

（2）pom.xml【各个包的说明在注释】

（5）mybatis的配置文件mybatis-spring.xml

  <configuration>
    <settings>
        <setting name="mapUnderscoreToCamelCase" value="true"/>
    settings>
    <typeAliases>
        <package name="entity"/>
    typeAliases>
  configuration>

（6）Navicat软件中创建mysql表【id设置成主键，且自增】，如图

（7）mybatis的映射文件mapper.xml

<mapper namespace="dao.CityDao">
    <insert id="insertCity" parameterType="City">
        insert into china (id,name,province) values (
            #{id},
            #{name},
            #{province}
            )
    insert>
mapper>

（8）dao包下的接口CityDao

package dao;


import entity.City;

public interface CityDao {
    public void insertCity(City city);
}

（9）entity包下的实体City

package entity;

public class City {
    private int id;
    private String name;
    private String province;
    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 String getProvince() {
        return province;
    }
    public void setProvince(String province) {
        this.province = province;
    }
}

（10）测试类

package test;


import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import dao.CityDao;
import entity.City;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:config/applicationContext.xml"})//,"classpath:mapper/mapper.xml"
public class testDemo {
    @Autowired
    private CityDao cityDao;
    @Test
    public void insert(){
        try {
            City city = new City();
            city.setId(3);
            city.setName("嘉兴");
            city.setProvince("浙江");
            cityDao.insertCity(city);
            System.out.println("insert successfully");
        } catch (Exception e) {
            // TODO: handle exception
            e.printStackTrace();
        }
    }
}
