問：假如id為非必需引數，可以為空，應該怎麼處理
@RequestMapping(value = "/get/{id}/{userId}", method = RequestMethod.GET)
public Result getMemberShip(@PathVariable("id") int id,@PathVariable("userId") int userId) {答
可以指定多個匹配路徑
@RequestMapping(value = {"/get/{userId}", "/get/{id}/{userId}"}, method = RequestMethod.GET)然後設定引數非必須
@PathVariable 示例
@ApiOperation("獲取訂單介面") @ApiImplicitParams({ @ApiImplicitParam(name = "pin", paramType = "path", dataType = "String", value = "賬號", required = true), @ApiImplicitParam(name = "phone", paramType = "path", dataType = "String", value = "電話號碼", required = false) }) @ApiResponses({@ApiResponse(code = 501, message = "自定義異常xxx"), @ApiResponse(code = 500, message = "500", response = Errors.class)}) @GetMapping(value = {"/list/{pin}/{phone}", "/list/{pin}"}) public List<OrderBaseVO> getOrderList(@PathVariable String pin, @PathVariable(required = false) String phone) { }
