地址簿功能代码

1. 地址簿功能

1.1 需求分析和设计

• 查询地址列表
• 新增地址
• 修改地址
• 删除地址
• 设置默认地址
• 查询默认地址

1.1.1 接口设计

根据上述原型图先粗粒度设计接口，共包含7个接口。

接口设计：

• 新增地址
• 查询登录用户所有地址
• 查询默认地址
• 根据id修改地址
• 根据id删除地址
• 根据id查询地址
• 设置默认地址

接下来细粒度分析每个接口，明确每个接口的请求方式、请求路径、传入参数和返回值。

1). 新增地址

2). 查询登录用户所有地址

3). 查询默认地址

4). 修改地址

5). 根据id删除地址

6). 根据id查询地址

7). 设置默认地址

1.1.2 表设计

用户的地址信息会存储在address_book表，即地址簿表中。具体表结构如下：

字段名	数据类型	说明	备注
id	bigint	主键	自增
user_id	bigint	用户id	逻辑外键
consignee	varchar(50)	收货人
sex	varchar(2)	性别
phone	varchar(11)	手机号
province_code	varchar(12)	省份编码
province_name	varchar(32)	省份名称
city_code	varchar(12)	城市编码
city_name	varchar(32)	城市名称
district_code	varchar(12)	区县编码
district_name	varchar(32)	区县名称
detail	varchar(200)	详细地址信息	具体到门牌号
label	varchar(100)	标签	公司、家、学校
is_default	tinyint(1)	是否默认地址	1是 0否

这里面有一个字段is_default，实际上我们在设置默认地址时，只需要更新这个字段就可以了。

Mapper层

创建AddressBookMapper.java

package com.sky.mapper;

import com.sky.entity.AddressBook;
import org.apache.ibatis.annotations.*;
import java.util.List;

@Mapper
public interface AddressBookMapper {

    /**
     * 条件查询
     * @param addressBook
     * @return
     */
    List<AddressBook> list(AddressBook addressBook);

    /**
     * 新增
     * @param addressBook
     */
    @Insert("insert into address_book" +
            "        (user_id, consignee, phone, sex, province_code, province_name, city_code, city_name, district_code," +
            "         district_name, detail, label, is_default)" +
            "        values (#{userId}, #{consignee}, #{phone}, #{sex}, #{provinceCode}, #{provinceName}, #{cityCode}, #{cityName}," +
            "                #{districtCode}, #{districtName}, #{detail}, #{label}, #{isDefault})")
    void insert(AddressBook addressBook);

    /**
     * 根据id查询
     * @param id
     * @return
     */
    @Select("select * from address_book where id = #{id}")
    AddressBook getById(Long id);

    /**
     * 根据id修改
     * @param addressBook
     */
    void update(AddressBook addressBook);

    /**
     * 根据 用户id修改 是否默认地址
     * @param addressBook
     */
    @Update("update address_book set is_default = #{isDefault} where user_id = #{userId}")
    void updateIsDefaultByUserId(AddressBook addressBook);

    /**
     * 根据id删除地址
     * @param id
     */
    @Delete("delete from address_book where id = #{id}")
    void deleteById(Long id);

}

创建AddressBookMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >

            <if test="label != null">
                label = #{label},
            </if>
            <if test="isDefault != null">
                is_default = #{isDefault},
            </if>
        </set>
        where id = #{id}
    </update>
