I'm looking to learn Spring Security with Grails but I can't find any intensive course that is built with Grails. My question is, since Grails 3 is built on top of Spring Boot, can I use Spring Boot Spring Security configuration for my Grails 3 app?
Yes.
There are several security related Guides at http://guides.grails.org.
Some documentation you might find helpful:

I am in the process of building a set of shared libraries using custom Spring Boot starter auto configuration per guidance from https://docs.spring.io/spring-boot/docs/2.6.7/reference/htmlsingle/#features.developing-auto-configuration. Great feature offered by Spring Boot by the way! My question is that how does Spring Native support these types of custom Spring Boot Starter libraries? Are extra reflection configurations or native hints required? I have been evaluating Spring Native and I am very excited about the performance boost it brings to Spring Boot apps! I am eagerly awaiting Spring Boot 3 GA to be released! Any advice on how Spring Boot 3 and/or Spring Native handles custom Spring Boot starter libraries and if any extra configurations are required will be greatly appreciated!
I reached out to Sébastien Deleuze, one of the members on Spring Native team, and his response to my question is as follows. Thanks Sébastien!
"Spring Native and the upcoming Spring Boot 3 should support this kind of autoconfiguration if they follow certain guidelines, like using #Configuration(proxyBeanMethods=false).
See https://docs.spring.io/spring-native/docs/current/reference/htmlsingle/#how-to-contribute-design for more details.
Spring Boot 3 will likely define more clearly the guidelines."
We have started new project on spring stack and using latest versions. But we have workflow requirement and I used activiti in past. But as I see there is no spring boot 2 support for activiti and camunda. Can anybody suggest which BPM is best that can be integrated with spring boot 2.
You will find a bunch of Spring Boot 2 starters in the Flowable github repo.
The documentation explains step-by-step how to create a BPM enabled Spring Boot application. There is also the blog post The road to Spring Boot 2.0 that the improved support for Flowable within Spring Boot as part of the Flowable 6.3.0 release.
You ask for suggestions on which BPM is best. Well, I cannot be objective since I am part of the Flowable Team, but I can say that our Spring Boot implementation is pretty neat:
All engines are supported (BPMN, CMMN, DMN), both embedded and exposing their respective REST APIs.
There is an automatic configuration of Spring Security to use the Flowable IDM engine (in case no other custom security is configured).
There is no "EE" version of the starter. Flowable provides Spring Boot 2 support 100% Open Source.
The Spring Actuator integration is quite powerful.
Did I mention Open Source? ;-)
In order to get the all engines you would need to use the flowable-spring-boot-starter(-rest) dependency. The (-rest) needs to be used if you want the Flowable REST APIs to be automatically configured.
There is also the option to run the BPMN, CMMN or DMN engines in standalone mode. For that you would need one of the following dependencies:
flowable-spring-boot-starter-process(-rest)
flowable-spring-boot-starter-cmmn(-rest)
flowable-spring-boot-starter-dmn(-rest)
So, compare for yourself, but for me, it's pretty clear and of course I am open to discussion.
The Activiti is working on Activiti Cloud fully based on Spring Boot 2 and Spring Cloud Finchley (targeting kubernetes deployments, but it can be used outside kubernetes if that is not your thing) if you are looking for a BPMN runtime for Cloud Native applications. We are working hard on releasing the first Beta1 release at the moment, and we will very welcome feedback about it. Hope this helps.
If you use the camunda-bpm-spring-boot-starter you can write self contained services running camunda process engine with spring boot 2.
I'm building a new Spring mvc project and I'm quite bit impressed to see the performance benchmark of Cache2K. Hoever, I couldn't find any article on how to configure it with the current Spring MVC 4.2.4 and Java 1.8
It'll be a great help if somebody would help me with this.
P.P. - I'm using JavaConfig with complete annotation support
cache2k is integrated well with Spring and Spring Boot. See the documentation section in cache2k User Guide - Spring Framework
I have a requirement that I have to use Spring Boot with JSF as user interface, as of now I am using JSF with spring other modules. So, I want know the similarities, differences and advantages of Spring boot over Spring other modules.
Long story short, Spring Boot is highly opinionated wrapper for Spring Framework with a lot of production and cloud ready features. It can significantly reduce amount of your configuration if you follow conventions.
Start reading here.
You can not compare spring boot and spring framework. Spring Boot is a new project aims to help spring development by auto configuration of things required to run the spring application.
So, if you have spring application, you can use spring boot to run your Spring application without worrying about writing the XML configuration.
We're using Grails but with an existing model layer and DAO layer. We have an app written already in Spring MVC, using Spring for IoC and also Security. I'm trying to port the control and view over to Grails as a proof of concept. I have Grails working fine with IoC but am having some trouble getting Grails to work with Spring Security. I'm using 0.5.1 of the Spring security plugin for grails. I have an xml file with all of the spring security settings that work fine with the Spring MVC app, but I'm having trouble getting it to work in Grails. If anyone has any experience using Grails with Spring Security but not using the domain part of the Spring security plugin, then please let me know. Any advice, websites etc would be helpful.
You don't even need the Grails Spring Security Plugin,
You can integrate Spring Security 3 right into Grails as
it all Spring under the hood any way.
You only have to place the Security jars in the lib folder, add two entries into the web.xml and copy over your security applictionContext
This way you can use your existing Spring Security in your grails project
This worked for me.
