java - How do I read HTTP status code from RestTemplate? -

i call rest api using resttemplate. response don't has issues.i need http status code this.

request ok- 200

unauthorized - 400

according many post met bellow answer.

resttemplate template = new resttemplate(); httpentity<string> response = template.exchange(url, httpmethod.post, request, string.class);  string resultstring = response.getbody(); httpheaders headers = response.getheaders(); 

in here used exchange method response.(template.exchange....) used

postforobject method

this code

public balancecheckresponse accounttotal(string counteralias, string counterauth, string subscribertype,         string subscribervalue, string accessmode, string token) {      balancecheckresponse objresponse = new balancecheckresponse();      try {          balancecheckrequest objrequest = new balancecheckrequest();         objrequest.setcounteralias(counteralias);         objrequest.setcounterauth(counterauth);         objrequest.setsubscribertype(subscribertype);         objrequest.setsubscribervalue(subscribervalue);         objrequest.setaccessmode(accessmode);          resttemplate rsttemp = new resttemplate();         final string url = "https://ideabiz.lk/apicall/startpoint/v1/balancecheck";         list<httpmessageconverter<?>> messageconverters = new arraylist<httpmessageconverter<?>>();         mappingjackson2httpmessageconverter map =new mappingjackson2httpmessageconverter();         messageconverters.add(map);         //messageconverters.add(new stringhttpmessageconverter());         rsttemp.setmessageconverters(messageconverters);          httpheaders headers = new httpheaders();         headers.setcontenttype(mediatype.application_json);         headers.add("authorization", "bearer "+token);          httpentity<balancecheckrequest> entity = new httpentity<balancecheckrequest>(objrequest,headers);         objresponse = rsttemp.postforobject(url,entity, balancecheckresponse.class  );       } catch (exception e) {         e.printstacktrace();     }     system.out.println(objresponse.getcurrentbalance());     return objresponse;  } 

in code

objresponse.getheaders();

show error. can in here. have idea?

by default, resttemplate uses defaultresponseerrorhandler, throws exception if not receive 1 of responses considered successful. means in event of error, e.printstacktrace(); statement print stack trace. (which go unnoticed.)

if that's not enough you, there number of ways circumvent behavior, 1 of them supplying own error handler using seterrorhandler( responseerrorhandler errorhandler ).
