How do you configure spring security in Grails 7

A message from kapa.ai

To configure Spring Security in Grails 7, follow these steps: 1. Add the Spring Security Plugin Dependency In your

build.gradle

, add the following dependency:

groovy    dependencies {        implementation 'org.apache.grails:grails-spring-security:7.0.0-RC2'    }

Save the file and update your dependencies with:

./gradlew clean build

[Getting Started](https://apache.github.io/grails-spring-security/latest/core-plugin/guide/index.html#gettingStarted) 2. Run the Quickstart Script Generate the required domain classes (

User

,

Role

) and initial configuration by running:

./gradlew runCommand -Pargs="s2-quickstart com.yourapp User Role"

This will create the necessary domain classes and update your configuration files [Quick Start Guide](https://apache.github.io/grails-spring-security/latest/core-plugin/guide/index.html#gettingStarted). 3. Configure Security Settings The main configuration is done in

grails-app/conf/application.groovy

(or

application.yml

). For example, to use annotation-based security (the default):

groovy    grails.plugin.springsecurity.securityConfigType = "Annotation"

You can also use other configuration types like

InterceptUrlMap

or

Requestmap

if needed [Request Mappings](https://apache.github.io/grails-spring-security/latest/core-plugin/guide/index.html#requestMappings). 4. Secure Controllers or Actions Use the

@Secured

annotation to restrict access. For example:

groovy    import grails.plugin.springsecurity.annotation.Secured     @Secured('ROLE_ADMIN')    class SecureController {        def index() {            render 'Secure access only'        }    }

You can annotate the whole controller or individual actions [Apply the annotation](https://apache.github.io/grails-spring-security/latest/core-plugin/guide/index.html#8-apply-the-annotation). 5. (Optional) Configure Filter Chains If you are using REST APIs or need to separate stateless and stateful authentication, configure filter chains:

groovy    grails.plugin.springsecurity.filterChain.chainMap = [        [pattern: '/api/**', filters: 'JOINED_FILTERS,-anonymousAuthenticationFilter,-exceptionTranslationFilter,-authenticationProcessingFilter,-securityContextPersistenceFilter,-rememberMeAuthenticationFilter'],        [pattern: '/**', filters: 'JOINED_FILTERS,-restTokenValidationFilter,-restExceptionTranslationFilter']    ]

[REST Plugin Configuration](https://apache.github.io/grails-spring-security/latest/rest-plugin/guide/index.html#configuration) 6. Customize as Needed You can further customize authentication providers, static rules, and other settings in your configuration files as required. Summary: Install the plugin, run the quickstart, configure your security settings, and use annotations or mappings to secure your application. For more advanced setups (like REST), configure filter chains accordingly. All configuration is done in

application.groovy

or

application.yml

using the

grails.plugin.springsecurity

prefix. If you need more details or run into issues, refer to the [official documentation](https://apache.github.io/grails-spring-security/latest/core-plugin/guide/index.html#gettingStarted).
