Quarkus - Using Security with JPA

This guide demonstrates how your Quarkus application can use a database to store your user identities with Hibernate ORM or Hibernate ORM with Panache.


To complete this guide, you need:

  • less than 15 minutes

  • an IDE

  • JDK 1.8+ installed with JAVA_HOME configured appropriately

  • Apache Maven 3.6.2+


In this example, we build a very simple microservice which offers three endpoints:

  • /api/public

  • /api/users/me

  • /api/admin

The /api/public endpoint can be accessed anonymously. The /api/admin endpoint is protected with RBAC (Role-Based Access Control) where only users granted with the admin role can access. At this endpoint, we use the @RolesAllowed annotation to declaratively enforce the access constraint. The /api/users/me endpoint is also protected with RBAC (Role-Based Access Control) where only users granted with the user role can access. As a response, it returns a JSON document with details about the user.


We recommend that you follow the instructions in the next sections and create the application step by step. However, you can go right to the completed example.

Clone the Git repository: git clone https://github.com/quarkusio/quarkus-quickstarts.git, or download an archive.

The solution is located in the security-jpa-quickstart directory.

Creating the Maven Project

First, we need a new project. Create a new project with the following command:

mvn io.quarkus:quarkus-maven-plugin:1.3.1.Final:create \
    -DprojectGroupId=org.acme \
    -DprojectArtifactId=security-jpa-quickstart \
    -Dextensions="security-jpa, jdbc-postgresql, resteasy, hibernate-orm-panache"
cd security-jpa-quickstart

Don’t forget to add the database connector library of choice. Here we are using PostgreSQL as identity store.

This command generates a Maven project, importing the security-jpa extension which allows you to map your security source to JPA entities.

Writing the application

Let’s start by implementing the /api/public endpoint. As you can see from the source code below, it is just a regular JAX-RS resource:

package org.acme.security.jpa;

import javax.annotation.security.PermitAll;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

public class PublicResource {

    public String publicResource() {
        return "public";

The source code for the /api/admin endpoint is also very simple. The main difference here is that we are using a @RolesAllowed annotation to make sure that only users granted with the admin role can access the endpoint:

package org.acme.security.jpa;

import javax.annotation.security.RolesAllowed;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

public class AdminResource {

    public String adminResource() {
         return "admin";

Finally, let’s consider the /api/users/me endpoint. As you can see from the source code below, we are trusting only users with the user role. We are using SecurityContext to get access to the current authenticated Principal and we return the user’s name. This information is loaded from the database.

package org.acme.security.jpa;

import javax.annotation.security.RolesAllowed;
import javax.inject.Inject;
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;

public class UserResource {

    public String me(@Context SecurityContext securityContext) {
        return securityContext.getUserPrincipal().getName();

Defining our user entity

We can now describe how our security information is stored in our model by adding a few annotations to our User entity:

package org.acme.security.jpa;

import javax.persistence.Entity;
import javax.persistence.Table;

import io.quarkus.hibernate.orm.panache.PanacheEntity;
import io.quarkus.security.common.BcryptUtil;
import io.quarkus.security.jpa.Password;
import io.quarkus.security.jpa.Roles;
import io.quarkus.security.jpa.UserDefinition;
import io.quarkus.security.jpa.Username;

@Table(name = "test_user")
@UserDefinition (1)
public class User extends PanacheEntity {
    @Username (2)
    public String username;
    @Password (3)
    public String password;
    @Roles (4)
    public String role;

     * Adds a new user in the database
     * @param username the user name
     * @param password the unencrypted password (it will be encrypted with bcrypt)
     * @param role the comma-separated roles
    public static void add(String username, String password, String role) { (5)
        User user = new User();
        user.username = username;
        user.password = BcryptUtil.bcryptHash(password);
        user.role = role;

The security-jpa extension is only initialized if there is a single entity annotated with @UserDefinition.

1 This annotation must be present on a single entity. It can be a regular Hibernate ORM entity or a Hibernate ORM with Panache entity as in this example.
2 This indicates the field used for the user name.
3 This indicates the field used for the password. This defaults to using bcrypt hashed passwords, but you can also configure it for clear text passwords.
4 This indicates the comma-separated list of roles added to the target Principal representation attributes.
5 This method allows us to add users while hashing the password with the proper bcrypt hash.

Configuring the Application

The security-jpa extension requires at least one datasource to access to your database.



In our context, we are using PostgreSQL as identity store. The database schema is created by Hibernate ORM automatically on startup (change this in production) and we initialise the database with users and roles in the Startup class:

package org.acme.security.jpa;

import javax.enterprise.event.Observes;
import javax.inject.Singleton;
import javax.transaction.Transactional;

import io.quarkus.runtime.StartupEvent;

public class Startup {
    public void loadUsers(@Observes StartupEvent evt) {
        // reset and load all test users
        User.add("admin", "admin", "admin");
        User.add("user", "user", "user");

It is probably useless but we kindly remind you that you must not store clear-text passwords in production environments ;-). As a result, the security-jpa defaults to using bcrypt-hashed passwords.

Testing the Application

The application is now protected and the identities are provided by our database. The very first thing to check is to ensure the anonymous access works.

$ curl -i -X GET http://localhost:8080/api/public
HTTP/1.1 200 OK
Content-Length: 6
Content-Type: text/plain;charset=UTF-8


Now, let’s try a to hit a protected resource anonymously.

$ curl -i -X GET http://localhost:8080/api/admin
HTTP/1.1 401 Unauthorized
Content-Length: 14
Content-Type: text/html;charset=UTF-8

Not authorized%

So far so good, now let’s try with an allowed user.

$ curl -i -X GET -u admin:admin http://localhost:8080/api/admin
HTTP/1.1 200 OK
Content-Length: 5
Content-Type: text/plain;charset=UTF-8


By providing the admin:admin credentials, the extension authenticated the user and loaded their roles. The admin user is authorized to access to the protected resources.

The user admin should be forbidden to access a resource protected with @RolesAllowed("user") because it doesn’t have this role.

$ curl -i -X GET -u admin:admin http://localhost:8080/api/users/me
HTTP/1.1 403 Forbidden
Content-Length: 34
Content-Type: text/html;charset=UTF-8


Finally, using the user user works and the security context contains the principal details (username for instance).

curl -i -X GET -u user:user http://localhost:8080/api/users/me
HTTP/1.1 200 OK
Content-Length: 4
Content-Type: text/plain;charset=UTF-8


Supported model types

  • The @UserDefinition class must be a JPA entity (with Panache or not).

  • The @Username and @Password field types must be of type String.

  • The @Roles field must either be of type String or Collection<String> or alternately a Collection<X> where X is an entity class with one String field annotated with the @RolesValue annotation.

  • Each String role element type will be parsed as a comma-separated list of roles.

Storing roles in another entity

You can also store roles in another entity:

@Table(name = "test_user")
public class User extends PanacheEntity {
    public String name;

    public String pass;

    public List<Role> roles = new ArrayList<>();

public class Role extends PanacheEntity {

    @ManyToMany(mappedBy = "roles")
    public List<ExternalRolesUserEntity> users;

    public String role;

Password storage and hashing

By default, we consider passwords to be stored hashed with bcrypt under the Modular Crypt Format (MCF).

When you need to create such a hashed password we provide the convenient String BcryptUtil.bcryptHash(String password) function, which defaults to creating a random salt and hashing in 10 iterations (though you can specify the iterations and salt too).

with MCF you don’t need dedicated columns to store the hashing algo, the iterations count or the salt because they’re all stored in the hashed value.

WARN: you can also store passwords in clear text with @Password(PasswordType.CLEAR) but we strongly recommend against it in production.
