How to configure Spring's RestTemplate to return null when HTTP status of 404 is returned


java spring rest jaxb 

Foo foo = null;try {    foo = restTemplate.getForObject(url, Foo.class, vars);} catch (HttpClientErrorException ex)   {    if (ex.getStatusCode() != HttpStatus.NOT_FOUND) {        throw ex;    }}

java spring rest jaxb

To capture 404 NOT FOUND errors specifically you can use HttpClientErrorException.NotFound

Foo foo;    try {    foo = restTemplate.getForObject(url, Foo.class, vars);} catch (HttpClientErrorException.NotFound ex)   {    foo = null;}

java spring rest jaxb

to capture server related error, this will handle internal server error,

}catch (HttpServerErrorException e) {        log.error("server error: "+e.getResponseBodyAsString());        ObjectMapper mapper = new ObjectMapper();        EventAPIResponse eh = mapper.readValue(e.getResponseBodyAsString(), EventAPIResponse.class);        log.info("EventAPIResponse toString "+eh.toString());
