Calling a Spring controller from itself based on the response - rest

Question

We have a requirement where...when we get a request to our controller we make a call to another api and based on the other api response we have to retrigger the request to controller with different parameter
#RequestMapping(value = "/search", method = RequestMethod.GET, produces = "application/json")
public Map<String, Account> searchEndpoint(#RequestParam(name = "query", required = true) String query) {
RequestPayload req = new RequestPayload(query);
SearchResponse searchResponse = http.executeSecurePost(this.searchUrl, req, SearchResponse.class);
if(("particularModel").equalsIgnoreCase(searchResponse.getModel()))
{
String differentQueryParameter = searchResponse.getName();
searchEndpoint(differentQueryParameter);
}
else {
//do something else
}
return json response;
}
when i do like this ...it's working fine where it's making the second call and getting the new response and returns ...but again a third query where this time is the original query get's fired. Not sure why the third query is fired. Any help will be appreciated.

Answer 1

calling your handler again and again it may result in a recursive function. you could avoid this kind of programming .you put the logic for calling the api in service method and do it .
#RequestMapping(value = "/search", method = RequestMethod.GET, produces = "application/json")public Map<String, Account> searchEndpoint(#RequestParam(name = "query", required = true) String query) {
//put this logic in service
RequestPayload req = new RequestPayload(query);
SearchResponse searchResponse = http.executeSecurePost(this.searchUrl, req, SearchResponse.class);
if(("particularModel").equalsIgnoreCase(searchResponse.getModel()))
{
String differentQueryParameter = searchResponse.getName();
//put this logic in service and just call it
RequestPayload req = new RequestPayload(query);
SearchResponse searchResponse = http.executeSecurePost(this.searchUrl, req, SearchResponse.class)
}
else {
//do something else
}
return json response;
}
