import lombok.Data;

@Data
public class P {
    private String name;
    private String operationId;

    @Data
    public static class Operation {
        private Timestamp ts;
        private String id;
    }

}

我想用一个使用join的查询来填充这两个类的字段

<select id="getAllP" resultType="com.mappers.P">
        SELECT t."name" as name, t."operationId" as operationId,  o."ts" as ts, o."id" as id
        FROM  FROM "P"  t JOIN "Operation" o ON t."operationId" = o."id"  
    </select>

如果离开 resultType = "com.mappers.P" 在这个表单中，只有外部类的字段被填充，如果 resultType = "com.mappers.P & Operation" 那么只有内部一个，如何保证两个类的字段都被填充？提前谢谢
