java.lang.ClassNotFoundException：org.springframework.core.annotation.MergedAnnotations

Question

我提供方法名称时使用ControllerLinkBuilder时遇到问题，如果我不运行它并显示结果，它将抛出错误。

错误似乎是jar问题，但我尝试使用的其他版本也仍然相同'spring-boot-starter-hateoas'，它无法识别RepresentationModel＆ControllerLinkBuilderlinkTo的包

@GetMapping("/{businessclass}/lists/_generic")
public  ResponseEntity<POLineResponse>  businessClass(@PathVariable final String businessclass,
        @RequestParam String _fields, @RequestParam("company") String company) {
     logger.info("Entering into businessClass {} params{} ",businessclass, _fields);

     Page<PurchaseOrderLineDTO> page= mockFsmService.generateMockPurchaseOrderLines();

     POLineResponse polR = new POLineResponse (page.getContent(),page.getTotalElements());
     //polR.add(linkTo(LoadTestController.class).businessClass(businessclass,_fields,company)).withSelfRel();
    //polR.add(ControllerLinkBuilderlinkTo(LoadTestController.class).withSelfRel());

      Link selfLink = ControllerLinkBuilder.linkTo(methodOn(LoadTestController.class).businessClass(businessclass, _fields, company))
      .withSelfRel();

    polR.add(selfLink);
     return new ResponseEntity<>(polR, HttpStatus.OK);
}
