Integrate IDGen Service

Describes how to integrate with DIGIT's ID Gen service

Overview

This page provides the steps to integrate with the IDGen Service. Each application needs to have a unique ID. The IDGen service generates these unique IDs. ID format can be customised via configuration in MDMS.

Steps

Add the ID format that needs to be generated in this file - Id Format Mdms File. The following config has been added for this module:

{
"format": "PB-BTR-[cy:yyyy-MM-dd]-[SEQ_EG_BTR_ID]",
"idname": "btr.registrationid"
}

Restart the IDGen service and MDMS service and port-forward IDGen service to port 8285:

kubectl port-forward <IDGEN_SERVICE_POD_NAME> 8285:8080

Note that you can set the ID format in the application.properties file of IDGen service and run the service locally if you don't have access to a DIGIT environment.

Hit the below curl to verify that the format is added properly. The "ID" name needs to match exactly with what was added in MDMS.

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": "btr.registrationid"
        }
    ]
}'

Once verified, we can call the ID generation service from within our application and generate the registrationId.
Add the following model POJOs under models folder:
IdGenerationRequest.java

package digit.web.models;

import com.fasterxml.jackson.annotation.JsonProperty;
import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.egov.common.contract.request.RequestInfo;

import java.util.List;

@Data
@AllArgsConstructor
@NoArgsConstructor
@Builder
public class IdGenerationRequest {

    @JsonProperty("RequestInfo")
    private RequestInfo requestInfo;

    private List<IdRequest> idRequests;

}

IdGenerationResponse.java

package digit.web.models;

import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.egov.common.contract.response.ResponseInfo;

import java.util.List;


@Data

public class IdGenerationResponse {

    private ResponseInfo responseInfo;

    private List<IdResponse> idResponses;

}

IdRequest.java

package digit.web.models;

import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;

import javax.validation.constraints.NotNull;


@Data
@AllArgsConstructor
@NoArgsConstructor
@Builder
public class IdRequest {

    @JsonProperty("idName")
    @NotNull
    private String idName;

    @NotNull
    @JsonProperty("tenantId")
    private String tenantId;

    @JsonProperty("format")
    private String format;

}

IdResponse.java

package digit.web.models;

import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;


@Data
@AllArgsConstructor
@NoArgsConstructor
@Builder
public class IdResponse {

    private String id;

}

In the BirthApplicationEnrichment class, update the enrichBirthApplication method as shown below:

public void enrichBirthApplication(BirthRegistrationRequest birthRegistrationRequest) {
        //Retrieve list of IDs from IDGen service
        List<String> birthRegistrationIdList = idgenUtil.getIdList(birthRegistrationRequest.getRequestInfo(), birthRegistrationRequest.getBirthRegistrationApplications().get(0).getTenantId(), "btr.registrationid", "", birthRegistrationRequest.getBirthRegistrationApplications().size());
        Integer index = 0;
        for(BirthRegistrationApplication application : birthRegistrationRequest.getBirthRegistrationApplications()) {
            // Enrich audit details
            AuditDetails auditDetails = AuditDetails.builder().createdBy(birthRegistrationRequest.getRequestInfo().getUserInfo().getUuid()).createdTime(System.currentTimeMillis()).lastModifiedBy(birthRegistrationRequest.getRequestInfo().getUserInfo().getUuid()).lastModifiedTime(System.currentTimeMillis()).build();
            application.setAuditDetails(auditDetails);

            // Enrich UUID
            application.setId(UUID.randomUUID().toString());

            // Set application number from IdGen
            application.setApplicationNumber(birthRegistrationIdList.get(index++));
            
            // Enrich registration Id
            application.getAddress().setRegistrationId(application.getId());

            // Enrich address UUID
            application.getAddress().setId(UUID.randomUUID().toString());
        }
    }

Make sure below ID generation host configuration is present in the application.properties file. Make sure to fill in the correct values for the host.

#Idgen Config
egov.idgen.host=http://localhost:8285/ #REPLACE
egov.idgen.path=egov-idgen/id/_generate
