I want to start with new scratch application using spring 2.5, I want to integrate hibernate also in same project, can anyone suggest ideas?
If you want to go down the Spring Boot road, there is plenty of documentation available:
First of all, check out this part of the documentation.
Next you can check out this sample application, as well as this sample application. Note that the aforementioned samples use Hibernate implicitly though the use of JPA.
You can also take a look at this blog post.

I have been trying to set up a Spring Web application to use Azure Active Directory.
All the samples that I have found online are based on Spring Boot, is there a simple example that shows setting up spring framework web app only without using Spring Boot?
I am having no luck finding stuff, I am also trying to figure out how to convert all the spring boot autoconfig. Surely there is a sample somewhere that makes it easy to use for a Spring Framework only web-app?
I was able to figure this out somewhat. I'm very new to OAuth so still trying to learn as I go.
Basically I followed the Spring Reference and got things working using the override auto-configuration sections at https://docs.spring.io/spring-security/reference/servlet/oauth2/index.html
It also helped that I updated the Spring Framework versions to the latest and made sure I used the correct dependencies according to that reference site
Is there a way to create a simple CRUD App using Spring Boot and an Existing Database?
You could look at Spring Roo. Its entire purpose is to allow rapid application generation. There is also support for reverse engineering an app from an existing database.
Version 2 will apparently also support Spring Boot, but I don't know if database reverse engineering already made it into v2. You could always try generating your application and adding Spring Boot later on.
I haven't much used it myself so unfortunately I can't offer you much guidance on its actual use - but you should be able to find some tutorials on Google, and StackOverflow contains several questions and answers on Spring Roo as well.
Is it possible to integrate activiti explorer maven plugin with activiti Spring boot app?, so that we can make use of activit-explorer to view deployed process in activit-spring boot engine.
I know we can use rest-api over spring boot to query process engine, but I want to know if it is possible to run the explorer over spring boot by adding it as a maven plugin during deployment?Or can we tweak the activit-explorer.war somehow to point to spring-boot activiti engine?
activiti-explorer.war is standalone webapp by itself. I've write some guideline on how to manually to embed activiti-explorer to you own app. http://blog.canang.com.my/2016/05/12/embedding-activiti-explorer-to-your-application/
Most probably step 5 in my blog is your solution.
btw, there's reason why the name is 'default'. I can't recall it atm
I thought of answering my own question so that it will be useful for other developers with similar requirement. If you want to make an eco-system where activiti-rest, explorer and your custom end points co-exist, please refer this thread from activit forum. I have tried this and is working fine. link to thread
I would like to give my observation here. In order to avoid getting into pulling source and trying to build myself, I achieved partial success, by installing the activit-explorer as part of the usual standalone installation.Started the standalone activiti-explorer using Apache-Tomcat but I configured the database for Activiti as same as (MYSQL in my case) I used in my spring-boot application to hit the common ground.
But apparently the activiti version in my spring boot app was 5.19.0.0 and that for activiti-explorer was 5.22.0.0, which created some misalignment for spring boot application startup to fail. I am hopeful that with matching versions it might succeed. When I get some more time on me I will try and update. Since then may be someone can use this route.
I am a newbie in web development. I'm using servlets and JSP for web development.However, I've learnt lately that Spring Framework is apt for that which incorporate servlets, jsp etc. So, my question is that can I now run my program using Spring framework ? Like, I have 2 jsp codes, and 1 servlet class. So, how can I migrate the code in Spring Framework ? what additional things or codes do I need to maintain ?
Migrating an existing J2EE project is easy.
You will get rid of a lot of "boilerplate" code in the process. The easiest way to do it in my opinion will be to use SpringToolSuite.
Import your project in STS and then add "Maven" nature to it. In the pom configuration you can edit all the jars that you need and mention the spring framework. Once all this is setup it will be just a matter of minutes to change the code if it is small.
You can follow these video tutorials about maven and spring to learn about it.

There are more tutorials by "New Circle training" on youtube for the same.
I would also recommend you to read Spring in action 3rd edition-Manning
This book is a must and the best way to learn spring framework. Hope this helps
I have a really simple question, that I just can't find the answer.
If I want to use only Spring Security, do I need Spring core or any other dependency?
In this link, in the bottom I see only spring security jars as dependencies, but still I couldn't get it to work. I only got it to work when I used a lot more of spring jars (core, context, and more).
So, what are the minimal dependencies I need for using Spring Security? All I need is an authorization and authentication framework, and I want as little dependencies as possible.
Thank you!
For every spring extension you need to use Srping core, because every extension is build on top of spring core
