Integrating with User service

c. Integration with User service - Integration with user service requires the following steps -

i) Create a new class under utils by the name of UserUtil and update the User POJO to have the following content -

@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
@Builder
public class User   {
        @JsonProperty("id")
        private Long id = null;

        @JsonProperty("uuid")
        private String uuid = null;

        @JsonProperty("userName")
        private String userName = null;

        @JsonProperty("password")
        private String password = null;

        @JsonProperty("salutation")
        private String salutation = null;

        private String gender = null;

        @JsonProperty("mobileNumber")
        private String mobileNumber = null;

        @JsonProperty("emailId")
        private String emailId = null;

        @JsonProperty("altContactNumber")
        private String altContactNumber = null;

        @JsonProperty("pan")
        private String pan = null;

        @JsonProperty("aadhaarNumber")
        private String aadhaarNumber = null;

        @JsonProperty("permanentAddress")
        private String permanentAddress = null;

        @JsonProperty("permanentCity")
        private String permanentCity = null;

        @JsonProperty("permanentPincode")
        private String permanentPincode = null;

        @JsonProperty("correspondenceCity")
        private String correspondenceCity = null;

        @JsonProperty("correspondencePincode")
        private String correspondencePincode = null;

        @JsonProperty("correspondenceAddress")
        private String correspondenceAddress = null;

        @JsonProperty("active")
        private Boolean active = null;

        @JsonProperty("locale")
        private String locale = null;

        @JsonProperty("type")
        private String type = null;

        @JsonProperty("signature")
        private String signature = null;

        @JsonProperty("accountLocked")
        private Boolean accountLocked = null;

        @JsonProperty("roles")
        @Valid
        private List<Role> roles = null;

        @JsonProperty("fatherOrHusbandName")

        private String photo = null;

        @JsonProperty("createdBy")
        private Long createdBy = null;

        public User addRolesItem(Role rolesItem) {
            if (this.roles == null) {
            this.roles = new ArrayList<>();
            }
        this.roles.add(rolesItem);
        return this;
        }

}

ii) Annotate the created UserUtil class with @Component and add the following code in the created class -

@Component
public class UserUtil {


    private ObjectMapper mapper;

    private ServiceRequestRepository serviceRequestRepository;

    private VTRConfiguration config;

    @Autowired
    public UserUtil(ObjectMapper mapper, ServiceRequestRepository serviceRequestRepository, VTRConfiguration config) {
        this.mapper = mapper;
        this.serviceRequestRepository = serviceRequestRepository;
        this.config = config;
    }

    /**
     * Returns UserDetailResponse by calling user service with given uri and object
     * @param userRequest Request object for user service
     * @param uri The address of the endpoint
     * @return Response from user service as parsed as userDetailResponse
     */

    public UserDetailResponse userCall(Object userRequest, StringBuilder uri) {
        String dobFormat = null;
        if(uri.toString().contains(config.getUserSearchEndpoint())  || uri.toString().contains(config.getUserUpdateEndpoint()))
            dobFormat="yyyy-MM-dd";
        else if(uri.toString().contains(config.getUserCreateEndpoint()))
            dobFormat = "dd/MM/yyyy";
        try{
            LinkedHashMap responseMap = (LinkedHashMap)serviceRequestRepository.fetchResult(uri, userRequest);
            parseResponse(responseMap,dobFormat);
            UserDetailResponse userDetailResponse = mapper.convertValue(responseMap,UserDetailResponse.class);
            return userDetailResponse;
        }
        catch(IllegalArgumentException  e)
        {
            throw new CustomException("IllegalArgumentException","ObjectMapper not able to convertValue in userCall");
        }
    }


    /**
     * Parses date formats to long for all users in responseMap
     * @param responeMap LinkedHashMap got from user api response
     */

    public void parseResponse(LinkedHashMap responeMap, String dobFormat){
        List<LinkedHashMap> users = (List<LinkedHashMap>)responeMap.get("user");
        String format1 = "dd-MM-yyyy HH:mm:ss";
        if(users!=null){
            users.forEach( map -> {
                        map.put("createdDate",dateTolong((String)map.get("createdDate"),format1));
                        if((String)map.get("lastModifiedDate")!=null)
                            map.put("lastModifiedDate",dateTolong((String)map.get("lastModifiedDate"),format1));
                        if((String)map.get("dob")!=null)
                            map.put("dob",dateTolong((String)map.get("dob"),dobFormat));
                        if((String)map.get("pwdExpiryDate")!=null)
                            map.put("pwdExpiryDate",dateTolong((String)map.get("pwdExpiryDate"),format1));
                    }
            );
        }
    }

    /**
     * Converts date to long
     * @param date date to be parsed
     * @param format Format of the date
     * @return Long value of date
     */
    private Long dateTolong(String date,String format){
        SimpleDateFormat f = new SimpleDateFormat(format);
        Date d = null;
        try {
            d = f.parse(date);
        } catch (ParseException e) {
            throw new CustomException("INVALID_DATE_FORMAT","Failed to parse date format in user");
        }
        return  d.getTime();
    }

    /**
     * enriches the userInfo with statelevel tenantId and other fields
     * @param mobileNumber
     * @param tenantId
     * @param userInfo
     */
    public void addUserDefaultFields(String mobileNumber,String tenantId, User userInfo){
        Role role = getCitizenRole(tenantId);
        userInfo.setRoles(Collections.singletonList(role));
        userInfo.setType("CITIZEN");
        userInfo.setUserName(mobileNumber);
        userInfo.setTenantId(getStateLevelTenant(tenantId));
        userInfo.setActive(true);
    }

    /**
     * Returns role object for citizen
     * @param tenantId
     * @return
     */
    private Role getCitizenRole(String tenantId){
        Role role = new Role();
        role.setCode("CITIZEN");
        role.setName("Citizen");
        role.setTenantId(getStateLevelTenant(tenantId));
        return role;
    }

    public String getStateLevelTenant(String tenantId){
        return tenantId.split("\\.")[0];
    }

}

iii) Create the following POJOs -

@AllArgsConstructor
@Getter
@NoArgsConstructor
public class CreateUserRequest {

    @JsonProperty("requestInfo")
    private RequestInfo requestInfo;

    @JsonProperty("user")
    private User user;

}
@Getter
@Setter
public class UserSearchRequest {

    @JsonProperty("RequestInfo")
    private RequestInfo requestInfo;

    @JsonProperty("uuid")
    private List<String> uuid;

    @JsonProperty("id")
    private List<String> id;

    @JsonProperty("userName")
    private String userName;

    @JsonProperty("name")
    private String name;

    @JsonProperty("mobileNumber")
    private String mobileNumber;

    @JsonProperty("aadhaarNumber")
    private String aadhaarNumber;

    @JsonProperty("pan")
    private String pan;

    @JsonProperty("emailId")
    private String emailId;

    @JsonProperty("fuzzyLogic")
    private boolean fuzzyLogic;

    @JsonProperty("active")
    @Setter
    private Boolean active;

    @JsonProperty("tenantId")
    private String tenantId;

    @JsonProperty("pageSize")
    private int pageSize;

    @JsonProperty("pageNumber")
    private int pageNumber = 0;

    @JsonProperty("sort")
    private List<String> sort = Collections.singletonList("name");

    @JsonProperty("userType")
    private String userType;

    @JsonProperty("roleCodes")
    private List<String> roleCodes;

}
@AllArgsConstructor
@NoArgsConstructor
@Getter
public class UserDetailResponse {
    @JsonProperty("responseInfo")
    ResponseInfo responseInfo;

    @JsonProperty("user")
    List<User> user;
}

v) Create a class by the name of UserService under service folder and add the following content to it -

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