Spring Boot + Java 11 + Mybatis：@Many 在 Annotations 方法中被忽略

我是 Mybatis 的新手，我在使用 @Many 获取数据时遇到了问题。

我有两个类，第二个类的对象是第一类对象 Set<> 的值；

类是：

public class InformationObjectMergedWithCopyrights {

    private Long id;
    private String titleLt;
    private String accountingNumber;
    private String inventoryNumber;
    private Long referenceYear;
    private Long duration;
    private String propertyRights;

    private Set<BavicCredit> creditsList = new HashSet<>();
    
    getters/setters, constructor, toString...
}

public class BavicCredit {

    private Long id;
    private Long informationObjectId;
    private String bavicLabel;
    private String bavicRole;
    
        getters/setters, constructor, toString...
}

我有 sql 提供程序，它生成查询字符串：

public class InformationObjectSqlProvider {
    public String selectByInventoryNumberConditionAccountingNumber(InventoryNumberReportParamsDao reportParamsDao) {
        
        StringBuilder sql = new StringBuilder("SELECT " +
            "io.ID AS id, " +
            "io.TITLE_LT AS titleLt, " +
            "io.ACCOUNTING_NUMBER AS accountingNumber, " +
            "io.INVENTORY_NUMBER AS inventoryNumber, " +
            "io.REFERENCE_YEAR AS referenceYear, " +
            "io.DURATION AS duration, " +
            "cvt.NAME AS propertyRights  " +
            "FROM SCHEMA_ONE.INFORMATION_OBJECT io " +
            "INNER JOIN SCHEMA_ONE.COPYRIGHTS c ON c.INFORMATION_OBJECT_ID = io.ID " +
            "INNER JOIN SCHEMA_TWO.CLASSIFIER_VALUES cv2 ON c.PROPERTY_RIGHTS = cv2.CODE " +
            "INNER JOIN SCHEMA_TWO.CLASSIFIER_VALUE_TRANSLATIONS cvt ON cv2.ID = cvt.CLASSIFIER_VALUE_ID AND cvt.LANGUAGE_ID = 1 " +
            "WHERE io.INVENTORY_NUMBER = #{reportParamsDao.inventoryNumberCode} ORDER BY accountingNumber ASC");

        return sql.toString();
    }
}

最后，我创建了一个映射器：

@Mapper
public interface InformationObjectMapper {

    InformationObjectSqlProvider provider = new InformationObjectSqlProvider();


    @SelectProvider(type = InformationObjectSqlProvider.class, method = "selectByInventoryNumberConditionAccountingNumber")
    @Results(value = {
        @Result(property = "creditsList",
            column = "SCHEMA_ONE.INF_OBJ_CLASIFFIER.INFORMATION_OBJECT_ID",
            javaType = Set.class, many = @Many(select = "selectCredits"))
    })
    List<InformationObjectMergedWithCopyrights> selectByInventoryNumberConditionAccountingNumber(@Param("reportParamsDao") InventoryNumberReportParamsDao reportParamsDao);

    @Select("SELECT * FROM SCHEMA_ONE.INF_OBJ_CLASSIFIER ioc WHERE ioc.INFORMATION_OBJECT_ID = #{informationObjetId} AND ioc.\"TYPE\" = 'CREDIT' ")
    @Results(value = {
        @Result(property = "bavicLabel", column = "BAVIC_LABEL"),
        @Result(property = "bavicRole", column = "ROLE")
    })
    Set<BavicCredit> selectCredits(@Param("informationObjetId") Long informationObjetId);
}

我的问题是此代码不返回 BavicCredit 类集。Set 总是空的，就像在第一个类中定义的一样。似乎根本没有调用 selectCredits 方法。外键存在于数据库中。我相信，我缺少一些小代码或属性映射。

Java 11、Spring Boot 2.5.0、Mybatis mybatis-spring-boot-starter 2.2.0、数据库Oracle com.oracle.database.jdbc ojdbc8

提前致谢。

PS 我已经在 MyBatis 中尝试了一对多的关系，但仍然缺少一些东西
