Integration with IdGen Service

b. Integration with IdGen - Integration with Idgen requires the following steps -

i) Add the Id Format that needs to be generated in this file - Id Format Mdms File

ii) For this tutorial, the following Id format has been added as part of this PR - Tutorial Id Format

iii) Now, restart IDGen service and Mdms service and port-forward IDGen service to port 8285 using -

kubectl port-forward <IDGEN_SERVICE_POD_NAME> 8285:8080

iv) Hit the following curl to verify that the format is added properly -

curl --location --request POST 'http://localhost:8285/egov-idgen/id/_generate' \
--header 'Content-Type: application/json' \
--data-raw '{
    "RequestInfo": {
        "apiId": "string",
        "ver": "string",
        "ts": null,
        "action": "string",
        "did": "string",
        "key": "string",
        "msgId": "string",
        "authToken": "6456b2cf-49ca-47c7-b7b6-c179f19614c7",
        "correlationId": "e721639b-c095-40b3-86e2-acecb2cb6efb",
        "userInfo": {
            "id": 23299,
            "uuid": "e721639b-c095-40b3-86e2-acecb2cb6efb",
            "userName": "9337682030",
            "name": "Abhilash Seth",
            "type": "EMPLOYEE",
            "mobileNumber": "9337682030",
            "emailId": "abhilash.seth@gmail.com",
            "roles": [
                {
                    "id": 281,
                    "name": "Employee"
                }
            ]
        }
    },
    "idRequests": [
        {
            "tenantId": "pb.amritsar",
            "idName": "vtr.registrationid"
        }
    ]
}'

v) Once verified, we can call idgen service from within our application and generate registrationId. For this, create a java class by the name of IdgenUtil under utils folder. Annotate this class with @Component and put the following content in the class -

@Component
public class IdgenUtil {
    
    @Value("${egov.idgen.host}")
    private String idGenHost;

    @Value("${egov.idgen.path}")
    private String idGenPath;

    @Autowired
    private ObjectMapper mapper;

    @Autowired
    private ServiceRequestRepository restRepo;

    public List<String> getIdList(RequestInfo requestInfo, String tenantId, String idName, String idformat, Integer count) {
        List<IdRequest> reqList = new ArrayList<>();
        for (int i = 0; i < count; i++) {
            reqList.add(IdRequest.builder().idName(idName).format(idformat).tenantId(tenantId).build());
        }

        IdGenerationRequest request = IdGenerationRequest.builder().idRequests(reqList).requestInfo(requestInfo).build();
        StringBuilder uri = new StringBuilder(idGenHost).append(idGenPath);
        IdGenerationResponse response = mapper.convertValue(restRepo.fetchResult(uri, request), IdGenerationResponse.class);

        List<IdResponse> idResponses = response.getIdResponses();

        if (CollectionUtils.isEmpty(idResponses))
            throw new CustomException("IDGEN ERROR", "No ids returned from idgen Service");

        return idResponses.stream().map(IdResponse::getId).collect(Collectors.toList());
    }
}

Add the following model POJOs under models folder -

vi) Add the following properties in application.properties file -
