Using Security with JDBC

This guide demonstrates how your Quarkus application can use a database to store your user identities.

Requisitos previos

To complete this guide, you need:

  • Roughly 15 minutes

  • An IDE

  • JDK 17+ installed with JAVA_HOME configured appropriately

  • Apache Maven 3.9.6

  • Optionally the Quarkus CLI if you want to use it

  • Optionally Mandrel or GraalVM installed and configured appropriately if you want to build a native executable (or Docker if you use a native container build)

Arquitectura

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.

Solución

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 el repositorio Git: git clone https://github.com/quarkusio/quarkus-quickstarts.git o descargue un archivo.

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

Creación del proyecto Maven

En primer lugar, necesitamos un nuevo proyecto. Cree un nuevo proyecto con el siguiente comando:

CLI
quarkus create app org.acme:security-jdbc-quickstart \
    --extension='elytron-security-jdbc,jdbc-postgresql,rest' \
    --no-code
cd security-jdbc-quickstart

To create a Gradle project, add the --gradle or --gradle-kotlin-dsl option.

For more information about how to install and use the Quarkus CLI, see the Quarkus CLI guide.

Maven
mvn io.quarkus.platform:quarkus-maven-plugin:3.10.0:create \
    -DprojectGroupId=org.acme \
    -DprojectArtifactId=security-jdbc-quickstart \
    -Dextensions='elytron-security-jdbc,jdbc-postgresql,rest' \
    -DnoCode
cd security-jdbc-quickstart

To create a Gradle project, add the -DbuildTool=gradle or -DbuildTool=gradle-kotlin-dsl option.

For Windows users:

  • If using cmd, (don’t use backward slash \ and put everything on the same line)

  • If using Powershell, wrap -D parameters in double quotes e.g. "-DprojectArtifactId=security-jdbc-quickstart"

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

This command generates a new project, importing the elytron-security-jdbc extension which is an wildfly-elytron-realm-jdbc adapter for Quarkus applications.

If you already have your Quarkus project configured, you can add the elytron-security-jdbc extension to your project by running the following command in your project base directory:

CLI
quarkus extension add elytron-security-jdbc
Maven
./mvnw quarkus:add-extension -Dextensions='elytron-security-jdbc'
Gradle
./gradlew addExtension --extensions='elytron-security-jdbc'

Esto añadirá lo siguiente a su archivo de construcción:

pom.xml
<dependency>
    <groupId>io.quarkus</groupId>
    <artifactId>quarkus-elytron-security-jdbc</artifactId>
</dependency>
build.gradle
implementation("io.quarkus:quarkus-elytron-security-jdbc")

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 Jakarta REST resource:

package org.acme.security.jdbc;

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

@Path("/api/public")
public class PublicResource {

    @GET
    @PermitAll
    @Produces(MediaType.TEXT_PLAIN)
    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.jdbc;

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

@Path("/api/admin")
public class AdminResource {

    @GET
    @RolesAllowed("admin")
    @Produces(MediaType.TEXT_PLAIN)
    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.jdbc;

import jakarta.annotation.security.RolesAllowed;
import jakarta.inject.Inject;
import jakarta.ws.rs.GET;
import jakarta.ws.rs.Path;
import jakarta.ws.rs.core.Context;
import jakarta.ws.rs.core.SecurityContext;

@Path("/api/users")
public class UserResource {

    @GET
    @RolesAllowed("user")
    @Path("/me")
    public String me(@Context SecurityContext securityContext) {
        return securityContext.getUserPrincipal().getName();
    }
}

Configuring the Application

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

quarkus.datasource.db-kind=postgresql
quarkus.datasource.username=quarkus
quarkus.datasource.password=quarkus
quarkus.datasource.jdbc.url=jdbc:postgresql:elytron-security-jdbc

In our context, we are using PostgreSQL as identity store, and we initialize the database with users and roles. We will use the salted and hashed version of password as a password in this example. We can use the BcryptUtil class to generate passwords in the Modular Crypt Format (MCF).

CREATE TABLE test_user (
  id INT,
  username VARCHAR(255),
  password VARCHAR(255),
  role VARCHAR(255)
);

INSERT INTO test_user (id, username, password, role) VALUES (1, 'admin', '$2a$10$Uc.SZ0hvGJQlYdsAp7be1.lFjmOnc7aAr4L0YY3/VN3oK.F8zJHRG', 'admin');
INSERT INTO test_user (id, username, password, role) VALUES (2, 'user','$2a$10$Uc.SZ0hvGJQlYdsAp7be1.lFjmOnc7aAr4L0YY3/VN3oK.F8zJHRG', 'user');

When signing up new users, we can encrypt their password as follows:

package org.acme.security.jdbc;

import io.quarkus.elytron.security.common.BcryptUtil;

public class AccountService {

    public void signupUser(String username, String password) {
        String encryptedPassword = BcryptUtil.bcryptHash(password);

        // store user with the encrypted password in the database
    }
}

We can now configure the Elytron JDBC Realm.

quarkus.security.jdbc.enabled=true
quarkus.security.jdbc.principal-query.sql=SELECT u.password, u.role FROM test_user u WHERE u.username=? (1)
quarkus.security.jdbc.principal-query.bcrypt-password-mapper.enabled=true (2)
quarkus.security.jdbc.principal-query.bcrypt-password-mapper.password-index=1
quarkus.security.jdbc.principal-query.bcrypt-password-mapper.salt-index=-1
quarkus.security.jdbc.principal-query.bcrypt-password-mapper.iteration-count-index=-1
quarkus.security.jdbc.principal-query.attribute-mappings.0.index=2 (3)
quarkus.security.jdbc.principal-query.attribute-mappings.0.to=groups

The elytron-security-jdbc extension requires at least one principal query to authenticate the user and its identity.

1 We define a parameterized SQL statement (with exactly 1 parameter) which should return the user’s password plus any additional information you want to load.
2 We configure the password mapper with the position of the password field in the SELECT fields and other information like salt, hash encoding, etc. Setting the salt and iteration count indexes to -1 is required for MCF.
3 We use attribute-mappings to bind the SELECT projection fields (i.e. u.role here) to the target Principal representation attributes.

In the principal-query configuration all the index properties start at 1 (rather than 0).

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

public%

Now, let’s try 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:password http://localhost:8080/api/admin
HTTP/1.1 200 OK
Content-Length: 5
Content-Type: text/plain;charset=UTF-8

admin%

By providing the admin:password 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:password http://localhost:8080/api/users/me
HTTP/1.1 403 Forbidden
Content-Length: 34
Content-Type: text/html;charset=UTF-8

Forbidden%

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

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

user%
