事實起因

最近在ORM上使用了ibatis,感覺挺繁瑣的，沒有jpa來的直接，但專案非要用也沒有辦法，最近在進行開發過程中出現了一個問題Invalid bound statement (not found)意思是說，你的xml對映和你的mapper方法不一致，這種不一致大叔總結幾點，如果你出現了這種問題可以按著下面幾後進行排查。

可能出現的原因

1. xml輸入引數型別不匹配，你可以改成parameterType="map"試試
2. xml返回引數型別問題，resultType="你的型別"，不要寫成resultMap="你的型別"
3. 返回的DTO與返回結果集名稱不匹配，這時你要對照型別的屬性，去為sql設定別名
4. yml檔案裡對ibatis配置有問題
   如下面程式碼:

@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;
}
 

對應的mapper程式碼：

  <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>
