java~springboot~ibatis Invalid bound statement (not found)缘由

事实原由

最近在ORM上使用了ibatis,感受挺繁琐的，没有jpa来的直接，但项目非要用也没有办法，最近在进行开发过程当中出现了一个问题Invalid bound statement (not found)意思是说，你的xml映射和你的mapper方法不一致，这种不一致大叔总结几点，若是你出现了这种问题能够按着下面几后进行排查。

可能出现的缘由

1. xml输入参数类型不匹配，你能够改为parameterType="map"试试
2. xml返回参数类型问题，resultType="你的类型"，不要写成resultMap="你的类型"
3. 返回的DTO与返回结果集名称不匹配，这时你要对照类型的属性，去为sql设置别名
4. yml文件里对ibatis配置有问题
   以下面代码:

@Getter
@Setter
public class BusinessCustomerDTO {
private Long id;
private String customerName;
private String contactPerson;
private Integer freeDays;
private String city;
private String province;
private String source;
private LocalDateTime enterDays;
private String leadingPerson;
}

对应的mapper代码：

<select id="getBusinessCustomers" parameterType="java.util.Map" resultType="cn.pilipa.customer.management.dto.BusinessCustomerDTO">
        select a.id,
        a.customer_name as customerName,
        a.city_code as city,
        a.province_code as province,
        a.customer_source as source,
        b.enter_storage_time as enterDays,
        b.current_salesperson as leadingPerson,
        c.contact_person as contactPerson from customer_base_info a
        inner join customer_business_info b on a.id=b.customer_id
        left join customer_contact_person  c on c.customer_id=a.id
        where c.is_main_contact=1
    </select>
