Step-1
First we need to add these dependencies in pom.xml
<!-- GSON -->
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.3.1</version>
</dependency>
<!-- http client -->
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.1.1</version>
</dependency>
class ProgramService {
@Override
public void addProgram(ProgramVO programVo) {
DefaultHttpClient client = new DefaultHttpClient();
//This code converting Java Object into JSON String
String json = new GsonBuilder().create().toJson(programVo, ProgramVO.class);
HttpResponse response =null;
try{
//Define a postRequest request
//Set the API media type in http content-type header
//Here we are setting content-type & Accept as JSON
postRequest.setHeader("content-type", "application/json");
postRequest.setHeader("Accept", "application/json");
//Set the request post body
postRequest.setEntity(new StringEntity(json));
//Send the request; It will immediately return the response in HttpResponse object if any
response = client.execute(postRequest);
System.out.println(response.toString());
//verify the valid error code first
int statusCode = response.getStatusLine().getStatusCode();
System.out.println(statusCode);
System.out.println(statusCode);
/*if (statusCode != 201)
{
throw new RuntimeException("Failed with HTTP error code : " + statusCode);
}*/
}
catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
finally
{
//Important: Close the connect
client.getConnectionManager().shutdown();
}
}
}
Rest Provider code :-
@Controller
@Scope("request")
@RequestMapping(value = "/v1/program")
public class ProgramController {
@Autowired
@Qualifier("ProgramService")
private IProgramService iProgramService;
public ProgramController() {
}
@RequestMapping(value =ProgramURIConstant.GET_PROGRAM, method = RequestMethod.GET, produces = { MediaType.APPLICATION_JSON_VALUE })
public @ResponseBody
ProgramVO findProgramById(@PathVariable("pid") String programid) {
ProgramVO result = iProgramService.findProgramByQId(programid);
return result;
}
@RequestMapping(value = ProgramURIConstant.ADD_PROGRAM, method = RequestMethod.POST, produces = { MediaType.APPLICATION_JSON_VALUE })
public @ResponseBody
String addProgram(@RequestBody ProgramVO programVO) {
programVO.setTimestamp(DateUtils.getCurrentTimeIntoTimestamp());
String result = iProgramService.addProgram(programVO);
return result;
}
@RequestMapping(value = "padd", method = RequestMethod.POST)
@ResponseStatus(value=HttpStatus.OK)
public @ResponseBody
String addProgramText(@RequestBody ProgramVO programVO) {
programVO.setTimestamp(DateUtils.getCurrentTimeIntoTimestamp());
String result = iProgramService.addProgram(programVO);
return result;
}
}
