[QUESTION] - CSE 3.X不支持multipart/form-data类型的RequestMapping了吗

###

非RestController的类，仅配置了RequestMapping，参数类型为@RequestPart @Parameter Part part，会走到PojoSwaggerGenerator

###

Start at org.apache.servicecomb.swagger.generator.ParameterGenerator.java:133 and trace how AbstractOperationGenerator.scanMethodParameters handles a non-RestController RequestMapping with @RequestPart Part. Reproduce the multipart/form-data case and determine whether the missing consumes value is expected; done means confirming the supported behavior or identifying the precise generator change needed.
