Exception when Using TestRestTemplate
You need the Apache HTTP client to be able to handle errors yourself with TestRestTemplate. This worked for me with your project
<dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <scope>test</scope> </dependency>(I also removed the duplicated junit, mockito and spring-test dependencies.)
I don't think Jackson will know how to convert JSON to Object. Try Map or something?
This solved my issue.

restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory()); restTemplate.setErrorHandler(new DefaultResponseErrorHandler() { public boolean hasError(ClientHttpResponse response) throws IOException{ HttpStatus statusCode = response.getStatusCode(); return statusCode.series() == HttpStatus.Series.SERVER_ERROR; } });
