CourseQuery Tools的入参类

@Data
public class CourseQuery {@ToolParam(required = false, description = "课程类型：编程、设计、自媒体、其它")private String type;@ToolParam(required = false, description = "学历要求：0-无、1-初中、2-高中、3-大专、4-本科及本科以上")private Integer edu;@ToolParam(required = false, description = "排序方式")private List<Sort> sorts;@Datapublic static class Sort {@ToolParam(required = false, description = "排序字段: price或duration")private String field;@ToolParam(required = false, description = "是否是升序: true/false")private Boolean asc;}
}

 CourseTools 大模型工具调用类

@RequiredArgsConstructor // 构造函数自动注入
@Component
public class CourseTools {private final ICourseService courseService;private final ISchoolService schoolService;private final ICourseReservationService reservationService;@Tool(description = "根据条件查询课程")public List<Course> queryCourse(@ToolParam(description = "查询的条件", required = false) CourseQuery query) {if (query == null) {return courseService.list(); // 查询所有课程}QueryChainWrapper<Course> wrapper = courseService.query().eq(query.getType() != null, "type", query.getType()) // type = '编程'.le(query.getEdu() != null, "edu", query.getEdu());// edu <= 2if (query.getSorts() != null && !query.getSorts().isEmpty()) {for (CourseQuery.Sort sort : query.getSorts()) {wrapper.orderBy(true, sort.getAsc(), sort.getField());}}return wrapper.list();}@Tool(description = "查询所有校区")public List<School> querySchool() {return schoolService.list();}@Tool(description = "生成预约单，返回预约单号")public Integer createCourseReservation(@ToolParam(description = "预约课程") String course,@ToolParam(description = "预约校区") String school,@ToolParam(description = "学生姓名") String studentName,@ToolParam(description = "联系电话") String contactInfo,@ToolParam(description = "备注", required = false) String remark) {CourseReservation reservation = new CourseReservation();reservation.setCourse(course);reservation.setSchool(school);reservation.setStudentName(studentName);reservation.setContactInfo(contactInfo);reservation.setRemark(remark);reservationService.save(reservation);return reservation.getId();}
}

特别注意：截止SpringAI的1.0.0-M6版本为止，SpringAI的OpenAiModel和阿里云百炼的部分接口存在兼容性问题，包括但不限于以下两个问题：

  • FunctionCalling的stream模式，阿里云百炼返回的tool-arguments是不完整的，需要拼接，而OpenAI则是完整的，无需拼接。

  • 音频识别中的数据格式，阿里云百炼的qwen-omni模型要求的参数格式为data:;base64,${media-data}，而OpenAI是直接{media-data}

由于SpringAI的OpenAI模块是遵循OpenAI规范的，所以即便版本升级也不会去兼容阿里云，除非SpringAI单独为阿里云开发starter，所以目前解决方案有两个：

  • 等待阿里云官方推出的spring-alibaba-ai升级到最新版本

  • 自己重写OpenAiModel的实现逻辑。

接下来，我们就用重写OpenAiModel的方式，来解决上述两个问题。
