Hi there,

I need a little help. I create a new REST Grails 3 app with this plugins:

compile 'org.grails.plugins:spring-security-core:3.2.1'
compile("org.grails.plugins:spring-security-rest:2.0.0.M2") {
  exclude group: 'org.grails.plugins', module: 'spring-security-core'
}
compile "org.grails.plugins:grails-spring-websocket:2.4.1"
compile "org.springframework.security:spring-security-config:5.0.3.RELEASE"
compile "org.springframework.security:spring-security-messaging:5.0.3.RELEASE"
compile "org.springframework.security:spring-security-web:5.0.3.RELEASE"

without the three last plugin I can start the app, but I need to secure the communication therefore the last 3 plugins.

try aligning the spring-security-config/spring-security-messaging versions with the spring-security-core version pulled in by the grails spring-security plugin (or rather defined by the spring-boot bom), i.e. 4.2.x.

compile "org.springframework.security:spring-security-config"
compile "org.springframework.security:spring-security-messaging"

(leaving out spring-security-web as that is already a dependency of the spring-security-core plugin).

depending on your setup, if you get any startup error related to boot autoconfiguration, you might have to exclude some auto-configuration classes, e.g. by putting this onto your Application class:

@EnableAutoConfiguration(exclude = [SecurityFilterAutoConfiguration, SpringBootWebSecurityConfiguration])

after that, you should be able to use a @Configuration bean extending AbstractSecurityWebSocketMessageBrokerConfigurer.

Thank you very much, it works. Would you mind updating the doc?

the docs are correct. the issue you were facing is just that you are using the spring-security-core grails plugin. the example in the docs is not. but sure, if you feel that is misleading, feel free to pull-request a hint reg. the grails spring-security-core plugin to the "misc" section at the bottom of the readme.

glad you got it working!
