I am bit new to spring boot and I am trying to design a search on user history which will provide 3 attributes to search user history {userId, searchKey, SearchValue}.

The search value datatype may differ based on search.

E.g

1. Userid=100, SearchKey=userAddress, searchValue='10 Downing Street'
2. Userid=100, SearchKey=external, searchValue=true
3. Userid=100, SearchKey=companyId, searchValue=25

I am trying to design a rest endpoint as below. This endpoint will integrate with react front end.

@GetMapping(value = "/searchUserHistoryByKeyValue")
public ResponseEntity<Object> searchUserHistoryByKeyValue(
      @RequestParam(value = "userId") int userId,
      @RequestParam(value = "searchKey") String searchKey,
      @RequestBody Object searchValue) {

          List<org.json.simple.JSONObject> entities =
              userHistoryService.searchUserHisotryByKeyValue(userId, searchKey, searchValue);
          return new ResponseEntity<>(entities, HttpStatus.OK);
}

I have implemented a dynamodb search on userhistory object which takes input as generic searchValue object as search filter as below. Dynamo DB Querying -

Also it shows below error as -

'TypeError: Failed to execute 'fetch' on 'Window': Request with GET/HEAD method cannot have body. '

I am not able to make this work? Appreciate your insights on this.

CodePudding user response：

It's HTTP protocol. You cannot pass any body object with the Get method. You have to use Post or Put method for using a body in HTTP request.

CodePudding user response：

@RequestBody not for single value it is intended for your custom object that is used with POST or PUT but in you case you can @RequestParam also if @RequestParam take attribute required with boolean vlue which tell your endpoint caller which params is optional if you set it False and which is required if you set it True
