Swashbuckle.AspNetCore.SwaggerGen.SwaggerGeneratorException: Conflicting method/path combination "POST api/app/XXX" for actions - 
SJ.ABP.XXXCenter.XXXA.XXXAppService.CreateAsync 
(SJ.ABP.XXXeCenter.Application),SJ.ABP.XXXCenter.XXXs.XXXAppService.CreateAsync (SJ.ABP.XXXCenter.Application). Actions 
require a unique method/path combination for Swagger/OpenAPI 3.0. Use ConflictingActionsResolver as a workaround
