Java 将ResultMap.xml映射到@Mapper类时，结果映射集合不包含值错误

我试图将查询结果（在@Mapper类内并使用@Select注释进行查询）绑定到Mapper.xml，因为我有一个非常复杂的POJO要映射到

这是我的密码：

mapper.class:

@Mapper
public interface MapMapper {

    @Select("select seat_id,row_pos,column_pos,is_assigned,team_id,map_id from t002_seat_mst where map_id=#{mapId}")
    @ResultMap("SeatsResultMap")
    MapDTO fetchMapSeatsByIdWhenNoTeam(int mapId);

}

由于我是从

application.properties

文件中提供jdbc属性的，所以我只在

mybatis config.xml

中使用了

。错了吗

这是我的application.properties文件：

<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE configuration
        PUBLIC '-//mybatis.org//DTD Config 3.0//EN'
        'http://mybatis.org/dtd/mybatis-3-config.dtd'>
<!--<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Confi 3.0//EN"
        "config//mybatis-3-config.dtd">-->
<configuration>

    <mappers>
        <mapper resource='config/SeatsMapper.xml'/>
    </mappers>
</configuration>

server.port=7777

spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.testWhileIdle=true
spring.datasource.validationQuery=SELECT 1

mybatis.config=classpath:config//mybatis-config.xml  

谁能帮我找出哪里出了问题？

谢谢。

尝试更改应用程序中的最后一行。属性：

mybatis.config=classpath:config//mybatis-config.xml

->

mybatis.config location=classpath:/config/mybatis-config.xml

非常感谢@ave。它成功了。更改很小，但非常有效。请尝试更改应用程序中的最后一行。属性：
