从浏览器访问/page先进入

public class TransmitUserInfoFilter implements Filter {

然后进入controller servie

 public PageModel<XXXX> page(Integer number, Integer size, String sortField, List<QueryCriteriaVo> criteriaVos) {

在service中进入feign

List<SysTenantDto> data = sysTenantFeignService.listByIds(tenantIds).getData();

@Configuration
public class FeignConfiguration implements RequestInterceptor {
    public FeignConfiguration() {
