QUESTION

How to toggle Quarkus file log handlers

Asked 2021-Jun-15 at 21:37

[Quarkus] How can we toggle the file log handlers

I am trying to use file handlers and want to configure if that file handler should be enabled or disabled

I am using this property

quarkus.log.handler.file."myHandler".enable=${myHandlerShouldBeEnabled}
quarkus.log.handler.file."myHandler".format=${someFormat}

quarkus.log.category."com.mypackage".handlers"=myHandler

But even on setting myHandlerShouldBeEnabled=false, logs are getting written to file.

Any suggestion will be helpful

This is indeed a bug that I reported here based on this question. It should be fixed by this Pull Request.

QUESTION

Quarkus JWT authentication doesn't work as a native app

Asked 2021-Jun-15 at 15:18

I created a new Quarkus app using the following command:

mvn io.quarkus:quarkus-maven-plugin:1.13.7.Final:create \
    -DprojectGroupId=com.okta.rest \
    -DprojectArtifactId=quarkus \
    -DclassName="com.okta.rest.quarkus.HelloResource" \
    -Dpath="/hello" \
    -Dextensions="smallrye-jwt"

Then, I modified the generated HelloResource to print out the user's name.

package com.okta.rest.quarkus;

import io.quarkus.security.Authenticated;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.SecurityContext;
import java.security.Principal;

@Path("/hello")
public class HelloResource {

    @GET
    @Path("/")
    @Authenticated
    @Produces(MediaType.TEXT_PLAIN)
    public String hello(@Context SecurityContext context) {
        Principal userPrincipal = context.getUserPrincipal();
        return "Hello, " + userPrincipal.getName() + "!";
    }

}

To make this work with Okta, I added a couple of properties to application.properties:

mp.jwt.verify.publickey.location=https://dev-1309757.okta.com/oauth2/default/v1/keys
mp.jwt.verify.issuer=https://dev-1309757.okta.com/oauth2/default

I fixed the HelloResourceTest so it expects a 401 now.

package com.okta.rest.quarkus;

import io.quarkus.test.junit.QuarkusTest;
import org.junit.jupiter.api.Test;

import static io.restassured.RestAssured.given;
import static org.hamcrest.CoreMatchers.is;

@QuarkusTest
public class HelloResourceTest {

    @Test
    public void testHelloEndpoint() {
        given()
          .when().get("/hello")
          .then()
             .statusCode(401);
    }

}

Then, I ran ./mvnw quarkus:dev. I'm able to generate a valid access token using OIDC Debugger and access this API using HTTPie.

Hello, matt.raible@okta.com!

However, if I build it as a native image using ./mvnw package -Pnative and try to run it, I'm unable to access the API.

I'm not sure if the Unable to get GraalVM version error is something to be worried about when building.

Please enable the quarkus-smallrye-jwt TRACE logging to see why the tokens are rejected. And indeed, as you have also found out, https protocol needs to be enabled in the native image, which can be done, as you have shown :-), by adding <quarkus.native.additional-build-args>--enable-url-protocols=https</quarkus.native.additional-build-args> to the native profile's properties in pom.xml.

This PR will ensure adding it manually won't be required.

thanks

QUESTION

How to retrieve a resource (object) with GET METHOD in REST API by using date as a @PathParam in Quarkus

Asked 2021-Jun-10 at 14:05

I am new to programming and I am trying to build a small dietary tracking app. I use quarkus RESTeasy JAX-RS and java to build my REST API. The user should be able to add foods he ate in days of the week.

The user must be able to retrieve the foods he ate based on the date. My issue is that I can't retrieve the food based on the date. When I use the Timestamp: "2021-06-10T08:44:45.9328079Z[UTC]" as the input date on my end point for GET Method, I get 400 BAD REQUEST in postman. When I retrieve foods based on userId it works fine.

Here is my code with the GET and POST methods:

@Path("/foods") public class Controller {

public static ArrayList<Object> foods = new ArrayList<>();

@GET
@Produces(MediaType.APPLICATION_JSON)
public Response getAllFood(){
    return Response.ok(foods).build();
}

@POST
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public Response addFood() throws ParseException {

    foods.add(new Food("Garlic", 30, Timestamp.from(Instant.now()), 1));
    foods.add(new Food("Onions", 20, Timestamp.from(Instant.now()), 2));
    return Response.ok(foods).build();

}

@Path("{userId}")
@GET
@Produces(MediaType.APPLICATION_JSON)
public static Response getFoodById(@PathParam("userId") int userId){
    for (Object food : foods){
        if (((Food)food).getUserId()==(userId)){
            return Response.ok(food).build();
        }
    }
    return null;
}

@Path("/second/{time}")
@GET
@Produces(MediaType.APPLICATION_JSON)
public Response getFoodByDate(@PathParam("time") Timestamp time){
    for (Object food : foods){
        if (((Food)food).getTime().toString().equals(time.toString())){
            return Response.ok(food).build();
        }
    }
    return null;
}

}

And here is the Food Class:

package org.acme;

import java.sql.Timestamp;

public class Food {

private String foodType;
private int portion;
private Timestamp time;
private int userId;

public Food(){}

public Food(String foodType, int portion, Timestamp time, int userId){
    this.foodType = foodType;
    this.portion = portion;
    this.time = time;
    this.userId = userId;

}

public String getFoodType() {
    return foodType;
}

public void setFoodType(String foodType) {
    this.foodType = foodType;
}

public int getPortion() {
    return portion;
}

public void setPortion(int portion) {
    this.portion = portion;
}

public Timestamp getTime() {
    return time;
}

public void setTime(Timestamp time) {
    this.time = time;
}

public int getUserId() {
    return userId;
}

public void setUserId(int userId) {
    this.userId = userId;
}

@Override
public String toString(){
    return foodType + ", " + portion + ", " + time + ", " + userId;
}

}

Ok - the reason why the error thrown from Postman is 400 bad request is due to your input parameter is incorrect.

Sample code with a change from the @PathParam to @RequestParam

@Path("/get/second/")
@GET
@Produces(MediaType.APPLICATION_JSON)
public Response getFoodByDate(@RequestParam("time") String dateString) throws ParseException{
   ArrayList<Food> foods = new ArrayList<>();
   DateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");

   Date requestedDate = sdf.parse(dateString);
   for (Object food : foods){
       if (((Food)food).getTime().equals(requestedDate)){
           return Response.ok(food).build();
       }
   }

   return null;
}

In this example, I changed your timestamp parameter as java.sql.Timestamp is thin wrapper around java.util.Date that allows the JDBC API to identify this as an SQL TIMESTAMP value, hence in this example it is not suggested to use timestamp.

Sample refactored Food class.

public class Food {
    private String foodType;
    private int portion;
    private Date time;
    private int userId;

    public Food(){}

    public Food(String foodType, int portion, Date time, int userId){
        this.foodType = foodType;
        this.portion = portion;
        this.time = time;
        this.userId = userId;

    } ... //getter and setter

Sample code to add food to your array list.

    DateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
    Food food1 = new Food("Garlic", 10, sdf.parse("2020-05-01"), 1);
    Food food2 = new Food("Onion", 20, sdf.parse("2020-05-02"), 1);
    Food food3 = new Food("Potato", 30, sdf.parse("2020-05-03"), 1);
    Food food4 = new Food("Tomato", 40, sdf.parse("2020-05-04"), 1);

    ArrayList<Food> foods = new ArrayList<>();
    foods.add(food1);
    foods.add(food2);
    foods.add(food3);
    foods.add(food4);

Full source code I tested against:

package org.example;

import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Date;

public class Main {

    public static void main(String[] args) throws ParseException {

        DateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
        String dateString = "2020-05-01"; //mocking request date from the @RequestParam
        Date requestedDate = sdf.parse(dateString);

        
        Food food1 = new Food("Garlic", 10, sdf.parse("2020-05-01"), 1);
        Food food2 = new Food("Onion", 20, sdf.parse("2020-05-02"), 1);
        Food food3 = new Food("Potato", 30, sdf.parse("2020-05-03"), 1);
        Food food4 = new Food("Tomato", 40, sdf.parse("2020-05-04"), 1);

        ArrayList<Food> foods = new ArrayList<>();
        foods.add(food1);
        foods.add(food2);
        foods.add(food3);
        foods.add(food4);
        
        for (Object food : foods){
            if (((Food)food).getTime().equals(requestedDate)){
                System.out.print(food);
            }
        }

    }
}

QUESTION

Debug Quarkus app packaged with quarkus-container-image-jib

Asked 2021-Jun-09 at 13:27

I would like to run the same image in our dev, staging and production environments. For our dev environment I would like to be able to connect a debugger.

I build the image for our Quarkus app like this (mvn package):

<dependencies>
    <dependency>
        <groupId>io.quarkus</groupId>
        <artifactId>quarkus-container-image-jib</artifactId>
    </dependency>
    ...
</dependencies

<properties>
    <quarkus.container-image.build>true</quarkus.container-image.build>
    <quarkus.jib.ports>8080,5005</quarkus.jib.ports>
    <quarkus.container-image.image>...</quarkus.container-image.image>
    ...
</properties>

<build>
    <plugins>
        <plugin>
            <groupId>io.quarkus</groupId>
            <artifactId>quarkus-maven-plugin</artifactId>
            <version>1.12.1.Final</version>
            <executions>
                <execution>
                    <goals>
                        <goal>build</goal>
                    </goals>
                    <phase>package</phase>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

Is it possible to start the application in debug mode while otherwise running with prod profile? Passing JAVA_OPTIONS=-Ddebug=true via an environment variable to the container causes a Exception in thread "main" java.nio.file.NoSuchFileException: /work/lib/deployment/deployment-class-path.dat.

If not, what would be the appropriate way to accomplish such a setup?

ANSWER

Answered 2021-Jun-09 at 13:27

There are a few ways to do that, but they all rely on the fact that in Quarkus you can control Jib to use whatever launch script you want for the container image. By default the container-image is created with a minimal java -jar ... style ENTRYPOINT, but that can be changed using the quarkus.jib.jvm-entrypoint.

If you use the default base image which already contains a run-java.sh script that provides a host of options (see https://hub.docker.com/r/fabric8/java-alpine-openjdk11-jre#startup-script-run-javash) then what you are trying to accomplish could be done by setting the following in application.properties:

quarkus.jib.jvm-entrypoint=/deployments/run-java.sh
quarkus.jib.environment-variables."JAVA_APP_DIR"=/work # this is needed so the script knows where the Quarkus jar is

Then launch the application using:

docker run --rm -p 8080:8080 -p 5005:5005 -e JAVA_DEBUG=true gandrian/getting-started:1.0.0-SNAPSHOT

Now the application will have the debug port open (but won't suspend) and you can connect to it with a debugger

QUESTION

How to initialize correctly the ConstraintVerifier for testing Optaplanner ConstraintStreams in Kotlin

Asked 2021-Jun-07 at 13:18

How can I initialize a ConstraintVerifier in Kotlin without using Drools and Quarkus? I already added the optaplanner-test JAR and the Maven Dependency for Optaplanner 8.6.0.Final and tried it the following way:

var constraintVerifier : ConstraintVerifier<GroupAssignmentConstraintProvider, GroupAssignmentSolution> =
    ConstraintVerifier.build(GroupAssignmentConstraintProvider(),
        GroupAssignmentSolution::class.java,
        GroupAssignment::class.java)

(ConstraintProvider: GroupAssignmentConstraintProvider, Solution: GroupAssignmentSolution, PlanningEntity: GroupAssignment) The Solution class gets a mutableSetOf Students, Lecturers and some configurations (min./max. number of participants/students for a group, optimal groupsize and weighted keywords) for solving.

The result for my test

    @Test
    fun lessThanMinGroupSize() {
    val students = Student().generateStudents(2)
    val configuration = Configuration(3, 9, 5, specialKeywords)

    val lecturer = mutableSetOf(
    Lecturer("4664807", mutableListOf(KeyWord("kotlin"), KeyWord("logistics"), KeyWord("java"), KeyWord("bigdata"), KeyWord("c")), mutableListOf("BIN", "BWI", "BEC"),
        mutableListOf(LocalDate.parse("2021-08-05"), LocalDate.parse("2021-08-08")),
        false, true))

    constraintVerifier.verifyThat(GroupAssignmentConstraintProvider::minGroupSize)
        .given(students, lecturer, configuration)
        .penalizes()
}

using the minGroupSize-Constraint:

    fun minGroupSize(constraintFactory: ConstraintFactory): Constraint {
    return constraintFactory
        .from(GroupAssignment::class.java)
        .groupBy(GroupAssignment::group, count())
        .filter { group, number ->
            number < group!!.minsize
        }
        .penalize("group min Conflict", ofHard(medium))
}

tells me: (GroupAssignmentTest.kt:65 refers to the .penalizes() in the Test)

java.lang.AssertionError: Broken expectation.

Constraint: groupAssignment.solver/group min Conflict

Apart from that, the constraints work.

I guess, I'm not initializing or using the ConstraintVerifier the right way. Is there anyone who can help me to solve the problem? Thank you!

ANSWER

Answered 2021-Jun-07 at 13:18

There are several issues with your test. First of all:

        .given(students, lecturer, configuration)

the given() call expects individual instances. You are giving it collections of instances, specifically a mutable set of students. Your constraint does not do from(Set.class) or anything of the like, and therefore it will not see these instances. You'll have to either enumerate your students, or don't give them at all, since your constraint does neither from() nor join() on a student class.

Furthermore, your constraint does from(GroupAssignment.class), yet I see no GroupAssignments among your given() arguments. Once again, the constraint stream has nothing to start from, and therefore the assertion message is correct - there was nothing to penalize.
