How to set up custom role provider in keycloak 18.0.2?

I want that user roles uploaded from db in keycloak. I have wrote RoleSPI for this, but roles don't load. My role-provider is displayed on server info.
I
I created CustomRoleProvider:
public class CustomRoleProvider implements RoleProvider {
#Override
public RoleModel addRealmRole(RealmModel realmModel, String s, String s1) {
return null;
}
#Override
public Stream<RoleModel> getRealmRolesStream(RealmModel realmModel, Integer integer, Integer integer1) {
return null;
}
#Override
public Stream<RoleModel> getRolesStream(RealmModel realmModel, Stream<String> stream, String s, Integer integer, Integer integer1) {
return null;
}
#Override
public boolean removeRole(RoleModel roleModel) {
return false;
}
#Override
public void removeRoles(RealmModel realmModel) {
}
#Override
public RoleModel addClientRole(ClientModel clientModel, String s, String s1) {
return null;
}
#Override
public Stream<RoleModel> getClientRolesStream(ClientModel clientModel, Integer integer, Integer integer1) {
return null;
}
#Override
public void removeRoles(ClientModel clientModel) {
}
#Override
public void close() {
}
#Override
public RoleModel getRealmRole(RealmModel realmModel, String s) {
System.out.println("getRealmRole()");
return roleModel;
}
#Override
public RoleModel getRoleById(RealmModel realmModel, String s) {
System.out.println("getRoleById()");
return roleModel;
}
#Override
public Stream<RoleModel> searchForRolesStream(RealmModel realmModel, String s, Integer integer, Integer integer1) {
System.out.println("searchForRolesStream()");
return roleModelStream;
}
#Override
public RoleModel getClientRole(ClientModel clientModel, String s) {
System.out.println("getClientRole()");
return roleModel;
}
#Override
public Stream<RoleModel> searchForClientRolesStream(ClientModel clientModel, String s, Integer integer, Integer integer1) {
System.out.println("searchForClientRolesStream()");
return roleModelStream;
}
}
My CustomRoleProviderFactory:
public class CustomRoleProviderFactory implements RoleProviderFactory {
#Override
public RoleProvider create(KeycloakSession keycloakSession) {
System.out.println("create");
return new CustomRoleProvider();
}
#Override
public void init(Config.Scope scope) {
}
#Override
public void postInit(KeycloakSessionFactory keycloakSessionFactory) {
}
#Override
public void close() {
}
#Override
public String getId() {
return "role-provider";
}
}
I noticed that the create method was not called after the start of keycloak.
There is org.keycloak.models.RoleProviderFactory in resources\META-INF\services packages:
com.healthec.keycloak.provider.CustomRoleProviderFactory
Do you have any ideas why roles don't loaded?

On reload of page, mvp4g history mechanism fails

I have implemented a history mechanism for my mvp4g project. When I traverse through the pages, I can see the url also getting changed. But on reload of any page other than home page, always home page gets displayed instead of the desired page?
This is my implementation:
#History(type = HistoryConverterType.SIMPLE)
public class CustomHistoryConverter implements HistoryConverter<AppEventBus> {
private CustomEventBus eventBus;
#Override
public void convertFromToken(String historyName, String param, CustomEventBus eventBus) {
this.eventBus = eventBus;
eventBus.dispatch(historyName, param);
}
public String convertToToken(String eventName, String name) {
return name;
}
public String convertToToken(String eventName) {
return eventName;
}
public String convertToToken(String eventName, String name, String type) {
return name;
}
public boolean isCrawlable() {
return false;
}
}
and event bus related code :
#Events(startPresenter=PageOnePresenter.class,historyOnStart=true)
public interface CustomEventBus extends EventBusWithLookup {
#Start
#Event(handlers = PageOnePresenter.class)
void start();
#InitHistory
#Event(handlers = PageOnePresenter.class)
void init();
#Event(handlers = PageTwoPresenter.class, name = "page2", historyConverter = CustomHistoryConverter.class)
void getPageTwo();
#Event(handlers = PageThreePresenter.class, name = "page3", historyConverter=CustomHistoryConverter.class)
void getPageThree();
#Event(handlers=PageOnePresenter.class, name = "page1", historyConverter=CustomHistoryConverter.class)
void getPageOne();
#Event(handlers=PageOnePresenter.class)
void setPageTwo(HistoryPageTwoView view);
#Event(handlers=PageOnePresenter.class)
void setPageThree(HistoryPageThreeView view);
}

The HistoryConverter needs to be improved.
In fact, that the event has no parameter, you should return an empty string. Update the HistoryConverter that it looks like that:
#History(type = HistoryConverterType.SIMPLE)
public class CustomHistoryConverter implements HistoryConverter<AppEventBus> {
private CustomEventBus eventBus;
#Override
public void convertFromToken(String historyName, String param, CustomEventBus eventBus) {
this.eventBus = eventBus;
// TODO handle the param in cases where you have more than one parameter
eventBus.dispatch(historyName, param);
}
public String convertToToken(String eventName, String name) {
return name;
}
public String convertToToken(String eventName) {
return "";
}
public String convertToToken(String eventName, String name, String type) {
return name - "-!-" type;
}
public boolean isCrawlable() {
return false;
}
}
Hope that helps.

how to work with WritableComparator Hadoop

Below are my code snippet for using WritableComparator, but it does not work
import org.apache.hadoop.io.WritableComparable;
import org.apache.hadoop.io.WritableComparator;
public class MovieComparator extends WritableComparator{
public MovieComparator(){
super(Movie.class);
}
#Override
public int compare(WritableComparable o,WritableComparable o2){
System.out.println("in compare");
Movie m = (Movie)o;
Movie m2 = (Movie)o2;
System.out.println(m.compareTo(m2));
return m.movieId.compareTo(m2.movieId);
}
}
public class Movie implements WritableComparable {
Text movieId;
Text movieTitle;
public Movie(Text movieId, Text movieTitle) {
this.movieId = movieId;
this.movieTitle = movieTitle;
}
public Movie(){
}
public String getMovieId() {
return movieId.toString();
}
public void setMovieId(String movieId) {
this.movieId = new Text(movieId);
}
public String getMovieTitle() {
return movieTitle.toString();
}
public void setMovieTitle(String movieTitle) {
this.movieTitle = new Text(movieTitle);
}
#Override
public void readFields(DataInput in) throws IOException {
//movieId = in.read;
movieId.readFields(in);
movieTitle.readFields(in);
}
#Override
public void write(DataOutput out) throws IOException {
//out.writeUTF(movieId);
//out.writeUTF(movieTitle);
movieId.write(out);
movieTitle.write(out);
}
#Override
public int compareTo(Movie o) {
// System.out.println("in compareTo");
int res=movieTitle.compareTo(o.movieTitle);
return res;
}
#Override
public int hashCode(){
return movieId.hashCode();
}
#Override
public boolean equals(Object o){
Movie m=(Movie)o;
return movieId.equals(m.movieId);
}
#Override
public String toString(){
return movieTitle.toString();
}
}
In driver class I am setting the comparator by below line
job.setSortComparatorClass(MovieComparator.class);
Can any body tell me where I am wrong in this at it gives exception below
14/09/08 14:17:03 WARN mapred.LocalJobRunner: job_local_0001
java.io.IOException: Spill failed

I found the issue that Instead of using super(Movie.class), I will have to use super(Movie.class,true). As by sending true, WritableComparator will instantiate the object other wise it will pass null in compare method

Robospice Cached Object is Always null

For some reason pulling a cached object back from the cache in Robospice is always null. Is there something I'm doing wrong?
getSpiceManager().execute(cardRequest, Card.class.getName(),
DurationInMillis.ONE_DAY, new CardRequestListener());
Is how it's executed. The spice manager is created as follows:
mSpiceManager = new SpiceManager(JacksonGoogleHttpClientSpiceService.class);
And the card class is as follows:
#JsonInclude(JsonInclude.Include.NON_NULL)
#JsonPropertyOrder({
"iosThumbHighRes",
"iosThumb",
"iosLargeHiRes",
"iosLargeHighRes",
"iosLarge"
})
public class Card {
#JsonProperty("iosThumbHighRes")
private String iosThumbHighRes;
#JsonProperty("iosThumb")
private String iosThumb;
#JsonProperty("iosLargeHiRes")
private String iosLargeHiRes;
#JsonProperty("iosLargeHighRes")
private String iosLargeHighRes;
#JsonProperty("iosLarge")
private String iosLarge;
private Map<String, Object> additionalProperties = new HashMap<String, Object>();
#JsonProperty("iosThumbHighRes")
public String getIosThumbHighRes() {
return iosThumbHighRes;
}
#JsonProperty("iosThumbHighRes")
public void setIosThumbHighRes(String iosThumbHighRes) {
this.iosThumbHighRes = iosThumbHighRes;
}
#JsonProperty("iosThumb")
public String getIosThumb() {
return iosThumb;
}
#JsonProperty("iosThumb")
public void setIosThumb(String iosThumb) {
this.iosThumb = iosThumb;
}
#JsonProperty("iosLargeHiRes")
public String getIosLargeHiRes() {
return iosLargeHiRes;
}
#JsonProperty("iosLargeHiRes")
public void setIosLargeHiRes(String iosLargeHiRes) {
this.iosLargeHiRes = iosLargeHiRes;
}
#JsonProperty("iosLargeHighRes")
public String getIosLargeHighRes() {
return iosLargeHighRes;
}
#JsonProperty("iosLargeHighRes")
public void setIosLargeHighRes(String iosLargeHighRes) {
this.iosLargeHighRes = iosLargeHighRes;
}
#JsonProperty("iosLarge")
public String getIosLarge() {
return iosLarge;
}
#JsonProperty("iosLarge")
public void setIosLarge(String iosLarge) {
this.iosLarge = iosLarge;
}
#Override
public String toString() {
return ToStringBuilder.reflectionToString(this);
}
#Override
public int hashCode() {
return HashCodeBuilder.reflectionHashCode(this);
}
#Override
public boolean equals(Object other) {
return EqualsBuilder.reflectionEquals(this, other);
}
#JsonAnyGetter
public Map<String, Object> getAdditionalProperties() {
return this.additionalProperties;
}
#JsonAnySetter
public void setAdditionalProperties(String name, Object value) {
this.additionalProperties.put(name, value);
}
}
Is there something else I need to set?
Thanks, Graeme

The Google Http Client uses the #Key annotation. You are using Jackson annotation which is not supported by Googe Http Java Client, as it provides an abstraction layer over all serialisation solutions (gson/jackson).

java- error when i am trying to convert xml response into pojo using xstream

I am getting an error for the following code in a java web app--
XStream xstream = new XStream();
apiresponse myClassObject;
myClassObject= xstream.fromXML(resp);
The error is shown for the line of code just above this line--
error="Type mismatch- cannot convert from Object to apiresponse"
Given below is the XML that I have to parse---
<apiresponse version="1" xmlns="http://ahrefs.com/schemas/api/links/1">
<resultset_links count="2">
<result>
<source_url>http://ahrefs.com/robot/</source_url>

</apiresponse>
I have created the following java classes to obtain data from above xml---
package com.arvindikchari.linkdatasmith.domain;
final public class apiresponse {
protected resultset_links rlinks;
public apiresponse() {
}
public resultset_links getRlinks()
{

What am I doing wrong here?

You have many errors, but the one corresponding to your message is you have to cast the result of xstream.fromXML to an apiresponse' object :
apiresponse result = (apiresponse)xstream.fromXML(resp);
Moreover, the code you provided (the Java classes) do not compile, there are many errors.
Here are some improvements :
Result.java :
#XStreamAlias("result")
public class Result {
protected String source_url;
protected String destination_url;
protected String source_ip;
protected String source_title;
protected String visited;
protected String anchor;
protected String rating;
protected String link_type;
protected Boolean is_nofollow;
public Result() {
}
public String getSource_url()
{
return source_url;
}
public void setSource_url(String source_url)
{
this.source_url=source_url;
}
public String getDestination_url()
{
return destination_url;
}
public void setDestination_url(String destination_url)
{
this.destination_url=destination_url;
}
public String getSource_ip()
{
return source_ip;
}
public void setSource_ip(String source_ip)
{
this.source_ip=source_ip;
}
public String getSource_title()
{
return source_title;
}
public void setSource_title(String source_title)
{
this.source_title=source_title;
}
public String getVisited()
{
return visited;
}
public void setVisited(String visited)
{
this.visited=visited;
}
public String getAnchor()
{
return anchor;
}
public void setAnchor(String anchor)
{
this.anchor=anchor;
}
public String getRating()
{
return rating;
}
public void setRating(String rating)
{
this.rating=rating;
}
public String getLink_type()
{
return link_type;
}
public void setLink_type(String link_type)
{
this.link_type=link_type;
}
public Boolean getIs_nofollow() {
return is_nofollow;
}
public void setIs_nofollow(Boolean is_nofollow) {
this.is_nofollow = is_nofollow;
}
ResultsetLinks.java :
#XStreamAlias("resultset_links")
public class ResultsetLinks {
#XStreamImplicit(itemFieldName="result")
protected List<Result> indivResult = new ArrayList<Result>();
public ResultsetLinks() {
}
public List<Result> getResult()
{
return indivResult;
}
public void setResult(List<Result> indiv_result)
{
this.indivResult =indiv_result;
}
}
ApiResponse.java :
#XStreamAlias("apiresponse")
public class ApiResponse {
#XStreamAlias("resultset_links")
protected ResultsetLinks rlinks;
public ApiResponse() {
}
public ResultsetLinks getRlinks()
{
return rlinks;
}
public void setRlinks(ResultsetLinks rlinks)
{
this.rlinks=rlinks;
}
}
And finally your code to unmarshall the XML :
XStream xstream = new XStream();
xstream.processAnnotations(ApiResponse.class);
xstream.processAnnotations(ResultsetLinks.class);
xstream.processAnnotations(Result.class);
ApiResponse result = (ApiResponse)xstream.fromXML(resp);
All this code is working fine with Xstream 1.4.2
Try to follow Sun's coding convention for your classes name, attributes names, etc...
Use XstreamAliases to adapt the Java class name to the XML name.
