原来

@RequestMapping(value = "/test", method = RequestMethod.POST, produces = "application/json;charset=UTF-8")

    @ApiImplicitParams({
        @ApiImplicitParam(name = "file", value = "文件", required = true),
        @ApiImplicitParam(name = "model", value = "型号", required = true),
        @ApiImplicitParam(name = "brandId", value = "品牌id", required = true),
        @ApiImplicitParam(name = "brand", value = "品牌名称", required = true),
        @ApiImplicitParam(name = "name", value = "产品名称", required = true),
    })
    public ResponseBody test(@RequestBody @RequestParam(value = "file") MultipartFile file,@RequestParam(value = "model") String model,@RequestParam(value = "brandId") Long brandId,@RequestParam(value = "brand") String brand,@RequestParam(value = "name") String name) throws Exception {
    

 

改成

 

@RequestMapping(value = "/test", method = RequestMethod.POST, produces = "application/json;charset=UTF-8")

        @ApiImplicitParam(name = "model", value = "型号", required = true,dataTypeClass =String.class),
        @ApiImplicitParam(name = "brandId", value = "品牌id", required = true,dataTypeClass =Long.class),
        @ApiImplicitParam(name = "brand", value = "品牌名称", required = true,dataTypeClass =String.class),
        @ApiImplicitParam(name = "name", value = "产品名称", required = true,dataTypeClass =String.class),

    })
    public ResponseBody test(@RequestBody @RequestParam(value = "file") MultipartFile file,@RequestParam(value = "model") String model,@RequestParam(value = "brandId") Long brandId,@RequestParam(value = "brand") String brand,@RequestParam(value = "name") String name) throws Exception {
