导入地址薄

通过userId将所有的地址修改为非默认地址

public void setDefault(AddressBook addressBook) {
    //1、将当前用户的所有地址修改为非默认地址 update address_book set is_default = ? where user_id = ?
    addressBook.setIsDefault(0);
    addressBook.setUserId(BaseContext.getCurrentId());
    addressBookMapper.updateIsDefaultByUserId(addressBook);

    //2、将当前地址改为默认地址 update address_book set is_default = ? where id = ?
    addressBook.setIsDefault(1);
    addressBookMapper.update(addressBook);
}

@Update("update address_book set is_default = #{isDefault} where user_id = #{userId}")
void updateIsDefaultByUserId(AddressBook addressBook);
