Spring Boot integrated keyload

Keywords: Programming Spring Docker Maven SSL

Preface

Reference in this article A Quick Guide to Using Keycloak with Spring Boot , sort out the problems encountered in the actual combat.

Docker installation keyload

Download mirroring

quay Download Image

docker pull quay.io/keycloak/keycloak

If you fail, try again.

Start keyclock

docker run -p 6060:8080 -e KEYCLOAK_USER=admin -e KEYCLOAK_PASSWORD=admin quay.io/keycloak/keycloak:latest

The port is mapped according to the actual situation.

The official is: docker run - P 8080:8080 - e keycloak? User = admin - e keycloak? Password = admin quay. IO / keycloak / keycloak: 9.0.2

At present, the latest version is 9.0.2. It is recommended to directly replace it with: latest, automatically pull the latest image.

Start successful:

This example starts in the local environment. If it starts in the production environment, SSL needs to be enabled.

Browsers and applications that interact with the realm must honor the SSL/HTTPS requirements defined by the SSL Mode or they will not be allowed to interact with the server.

Land

http://localhost:6060/auth

Click Administration Console

User name: admin Password: admin

Keyload configuration

Reference resources A Quick Guide to Using Keycloak with Spring Boot , the same configuration.

Spring Boot application launch

Download source code

Change configuration

keycloak.auth-server-url=http://localhost:6060/auth

keycloak.realm=SpringBootKeycloak
keycloak.resource=login-app
keycloak.public-client=true
keycloak.security-constraints[0].authRoles[0]=user
keycloak.security-constraints[0].securityCollections[0].patterns[0]=/customers/*

Change dependency

Part of the source code is dependent on and cannot be pulled.

Remove parent

    <parent>
        <groupId>com.baeldung</groupId>
        <artifactId>parent-boot-1</artifactId>
        <version>0.0.1-SNAPSHOT</version>
        <relativePath>../../parent-boot-1</relativePath>
    </parent>

Increase dependency management

    <properties>
        <spring-boot.version>1.5.22.RELEASE</spring-boot.version>
    </properties>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>${spring-boot.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

Increase dependency

        <dependency>
            <groupId>javax.xml.bind</groupId>
            <artifactId>jaxb-api</artifactId>
            <version>2.3.0</version>
        </dependency>
        <dependency>
            <groupId>org.keycloak</groupId>
            <artifactId>keycloak-spring-boot-starter</artifactId>
            <version>3.3.0.Final</version>
        </dependency>

Add Maven compiler plugin

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>10</source>
                    <target>10</target>
                </configuration>
            </plugin>
        </plugins>
    </build>
