I'm in the process of migrating away from the spring-security-saml module that has been deprecated to the new SAML support built into Spring Security 5+. I'd really like to not have to migrate this entire project from Spring Framework to String Boot at this time, so does anyone know if there is documentation on how to get Spring Security with SAML working on vanilla Spring Framework, everything I've seen has been only Spring Boot. Any help would be majestic!

I have a Spring 5 MVC application without Spring Boot that I need to migrate it's current Spring Security LDAP implementatino to a new Spring Security OAuth2 Resource Server implementation. I tried for several days without any luck to convert this application to Spring Boot and I am hoping I can do this migration without Spring Boot, the problem is that all the resources I found so far (examples,guides,etc.) only work with Spring Boot.
Any help is greatly appreciate it.
I am developing a client application for client_credentials grant type flow in OAUTH2.
I am not able to decide on which dependency to use in my project for this purpose among the following.
spring-boot-starter-oauth2-client
spring-cloud-starter-oauth2
spring-security-oauth2
I referred this documentation from spring-projects in which under client-support section it had a table describing the available options. But I am not able to understand which column is referring to which of the above dependencies.
I want to configure a WebClient or RestTemplate which retrieves the OAUTH2 token from the auth-server automatically before accessing a resource-server.
Please guide me in choosing the right artifact for my project.
If you are using Spring Boot you should choose org.springframework.boot:spring-boot-starter-oauth2-client.
This includes Spring Security's OAuth 2.0 Client support and provides Spring Boot auto-configuration to set up OAuth2/Open ID Connect clients.
You can read about how to configure client in the Spring Boot reference documentation.
You can also find additional details in the Spring Security reference documentation.
If you are not using Spring Boot then you should choose org.springframework.security:spring-security-oauth2-client. This also provides Spring Security's latest OAuth 2.0 Client support, but does not include the Spring Boot auto-configuration.
The corresponding documentation is also the Spring Security reference documentation.
The third dependency you mentioned org.springframework.security.oauth:spring-security-oauth2 should not be used because it is part of the legacy Spring Security OAuth project, which is now deprecated.
The functionality that this library provided has now been moved into Spring Security.
That is what the Migration Guide describes, the migration from the legacy project to the latest Spring Security support.
You should not use the org.springframework.cloud:spring-cloud-starter-oauth2 at this time, because it relies on the legacy OAuth support.
This is likely to change in the future, as the Spring Cloud team updates to the latest Spring Security support.
I am new to spring framework. I have a confusion regarding spring boot and spring cloud.
I used https://start.spring.io/ to initialize a spring boot application. I think I am using the spring boot framework. However, I would like to use some spring cloud dependencies such as spring-cloud-stream-binder-kafka.
Question 1: If I added this dependency above to my spring boot application, I am wondering if I still can go with the spring boot framework, or I have to change to spring cloud framework.
Question 2: I am wondering if there is any difference when deploying the spring boot or spring cloud application. Or, they just have the different frameworks, and we could deploy them in the same way.
Thank you so much!
You can use together Spring Boot and Spring Cloud packages.
Spring Boot is just a preconfigured Spring Framework with some extra functionalities. It also uses library versions compatibile with each other. Spring Cloud is also the part of the Spring ecosystem, contains libraries that mostly used in cloud applications.
In the background, these packages will pull all necessary Spring (and other) libraries into your project, as transitive dependencies.
So you can use the generated pom/gradle, and add other dependencies. In this case Spring boot will be your core and cloud add extras.
I just started learning spring cloud security and I have a basic question. How it is different from spring security? Do we need our application to be built on spring boot for using spring cloud security?
Thanks in advance.
Spring Security is a stand alone framework within Spring Framework. Spring Cloud Security is a Cloud Container and MicroServices focused Security Framework that provides Tokenised Security for Spring Boot applications.
how to implement the oauth2 server using jwt to get clients from database in spring boot 2.0 M7 ? there is any example, I just found an example with spring boot 2.0. M4 but seems it is not compatible with M7 , could someone please provide me a example ?
Support for the spring-security-oauth2 dependency was removed from Spring Boot 2.0 in favor of Spring Security 5’s first class OAuth support. Functionality from the Spring Security OAuth project is still being migrated to core Spring Security. For Authorization server and Resource server support which has not been migrated yet, you will need to add a dependency on an additional jar. See this documentation for more details.
