Using Security with JDBC

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

Prerequisites

要完成这个指南,你需要:

  • 大概15分钟

  • 编辑器

  • 安装JDK 11以上版本并正确配置了 JAVA_HOME

  • Apache Maven 3.8.1+

  • 如果你愿意的话,还可以选择使用Quarkus CLI

  • 如果你想构建原生可执行程序,可以选择安装Mandrel或者GraalVM,并正确配置(或者使用Docker在容器中进行构建)

Architecture

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.

Solution

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-jdbc-quickstart directory.

Creating the Maven Project

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

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

创建Grade项目,请添加 --gradle 或者 --gradle-kotlin-dsl 参数。

关于如何安装并使用Quarkus CLI的更多信息,请参考Quarkus CLI指南

Maven
mvn io.quarkus.platform:quarkus-maven-plugin:2.11.2.Final:create \
    -DprojectGroupId=org.acme \
    -DprojectArtifactId=security-jdbc-quickstart \
    -Dextensions="elytron-security-jdbc,jdbc-postgresql,resteasy-reactive" \
    -DnoCode
cd security-jdbc-quickstart

创建Grade项目,请添加 -DbuildTool=gradle 或者 -DbuildTool=gradle-kotlin-dsl 参数。

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"

This will add the following to your build file:

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 JAX-RS resource:

package org.acme.security.jdbc;

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;

@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 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;

@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 javax.annotation.security.RolesAllowed;
import javax.inject.Inject;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Context;
import javax.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.

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', 'admin', 'admin');
INSERT INTO test_user (id, username, password, role) VALUES (2, 'user','user', 'user');

It is probably useless, but we kindly remind you that you must not store clear-text passwords in production environment ;-). The elytron-security-jdbc offers a built-in bcrypt password mapper.

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.clear-password-mapper.enabled=true (2)
quarkus.security.jdbc.principal-query.clear-password-mapper.password-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.
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:admin 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: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

Forbidden%

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

user%

Advanced Configuration

This guide only covered an easy use case, the extension offers multiple datasources, multiple principal queries configuration as well as a bcrypt password mapper.

quarkus.datasource.db-kind=postgresql quarkus.datasource.username=quarkus quarkus.datasource.password=quarkus quarkus.datasource.jdbc.url=jdbc:postgresql:multiple-data-sources-users

quarkus.datasource.permissions.db-kind=postgresql quarkus.datasource.permissions.username=quarkus quarkus.datasource.permissions.password=quarkus quarkus.datasource.permissions.jdbc.url=jdbc:postgresql:multiple-data-sources-permissions

quarkus.security.jdbc.enabled=true quarkus.security.jdbc.principal-query.sql=SELECT u.password FROM test_user u WHERE u.username=? quarkus.security.jdbc.principal-query.clear-password-mapper.enabled=true quarkus.security.jdbc.principal-query.clear-password-mapper.password-index=1

quarkus.security.jdbc.principal-query.roles.sql=SELECT r.role_name FROM test_role r, test_user_role ur WHERE ur.username=? AND ur.role_id = r.id quarkus.security.jdbc.principal-query.roles.datasource=permissions quarkus.security.jdbc.principal-query.roles.attribute-mappings.0.index=1 quarkus.security.jdbc.principal-query.roles.attribute-mappings.0.to=groups
