查询数据库时报错Invalid bound statement (not found)错误

问题遇到的现象和发生背景

dao层和mapper.xml绑定不上namespace没错，id也能对上，target里面也有对应的xml文件

问题相关代码，请勿粘贴截图

这是dao层的代码

@Mapper
public interface paymentDao {

    //    查询
    payment select(Long id);

    //    插入
    Integer insert(payment payment);

    //    查询所有
    List<payment> getpayment();
}

```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">
<mapper namespace="cloud.Dao.paymentDao" >
    <resultMap id="paymentMap" type="entities.payment">
        <result property="id" column="id"/>
        <result property="serial" column="serial"/>
    </resultMap>
    <insert id="insert" parameterType="entities.payment" keyProperty="id" >
        insert into payment(serial) values(#{serial})
    </insert>
    <select id="select" resultMap="paymentMap" parameterType="long">
        select id,serial from payment where
        id=#{id}
    </select>
    <select id="getpayment" resultMap="paymentMap"  resultType="entities.payment">
        select * from  payment
    </select>
</mapper>
运行结果及报错内容

    问题已经解决，原因是application.yml的错误

    spring:
  application:
    name: cloud-dev

    看上面的项目结构可知，这个项目名cloud-dev是错的，删除后就没问题了
