vue3使用el-autocomplete请求远程数据

服务器端

@RestController
@RequestMapping("/teacher")
public class TeacherController {@Resourceprivate TeacherService teacherService;@GetMapping({"/v1/getTop10TeacherByName/","/v1/getTop10TeacherByName/{name}"})public ResultBean<List<EntryBean>> getTop10TeacherByName(@PathVariable(value = "name",required = false) String name) {List<EntryBean> list = teacherService.getTop10TeacherByName(name);return ResultBeanUtil.success(list);}}

返回数据示例，比如请求：/teacher/v1/getgetTop10TeacherByName/大，返回数据：

[{"code": 200,"msg": "成功","data": [{"id": 2,"name": "史宇大"},{"id": 1,"name": "蔡大伟"},{"id": 3,"name": "秦大"}]}
]

vue页面
