Could anybody suggest me some example application of jBPM, that uses Spring and Hibernate?
I am new to jBPM and need to get some reference application about it.
Here is the sample application: A sample application, intended to provide a foundation for developers who need to build applications using jBPM 5, Spring, and Hibernate

I am new to spring. I am not able to figure out how to write a spring project for creating DB connection using maven , without using spring -boot or hibernate. it is supposed to be a simple spring maven project.
can you help me with few sample codes.
Install the Spring tools suite plugin for eclipse from the following link.
With spring tools suite, access the spring dashboard
Select the Import Reference App, this will provide several example applications from the Spring guides, choose the example and the example will be installed onto your eclipse workspace. These examples are well documented , with clear instructions on how to run the project. Hopefully this should help you get started with learning Spring framework.
I have a set of projects in Spring framework and I have to Find the ones which can be converted to Spring boot.
Is there anything that is related to Spring framework and cannot be converted to spring boot ? In my research, I Could not Find something like that.
But does anyone know something, like a dependency, which would force the project to stay in Spring framework ?
Spring Boot uses the Spring Framework as a foundation and improvises on it. It simplifies Spring dependencies and runs applications straight from a command line. Spring Boot provides several features to help manage enterprise applications easily. Spring Boot is not a replacement for the Spring, but it’s a tool for working faster and easier on Spring applications. It simplifies much of the architecture by adding a layer that helps automate configuration and deployment while making it easier to add new features.
Most of the changes for migrating Spring Framework application to Spring Boot are related to configurations.This migration will have minimal impact on the application code or other custom components.Spring Boot brings a number of advantages to the development.
It simplifies Spring dependencies by taking the opinionated view.
Spring Boot provides a preconfigured set of technologies/framework to reduces error-prone configuration so we as a developer focused on building our business logic and not thinking of project setup.
You really don’t need those big XML configurations for your project.
Embed Tomcat, Jetty or Undertow directly.
Provide opinionated Maven POM to simplify your configurations.
Application metrics and health check using actuator module.
Externalization of the configuration files.
Good to refer this for migrating from Spring to Spring Boot application: https://www.javadevjournal.com/spring-boot/migrating-from-spring-to-spring-boot/
The other day I was playing around with the Spring ToolSuite (STS), and noticed that project types like ("classic") Spring Framework application and Spring MVC are underneath the "Spring legacy project". Does it mean that it is to be phased out, or it is under a deprecation process?
#M.Deinum is absolutely correct (in the comments above). The Spring Legacy Project wizard helps you to create Spring projects that do not use Spring Boot, which is the recommended way to create new Spring projects. Even though using the Spring framework without Spring Boot is absolutely fine and is not deprecated by any means, we are going to remove wizards and additional extras around that in future versions of the Spring tools in order to lead newbies in the direction of Spring boot when using the Spring tools.
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.
Can anyone clarify what are the differences between Spring Framework, Spring ROO, and Spring MVC ? I am really puzzled by these similar terms and cannot mangage find an answer.
It's really easy:
Spring Roo is a DEVELOPMENT-TIME tool, similar to Eclipse, IntelliJ, etc.
Spring Framework is a RUN-TIME framework.
Applications generated with Spring Roo at development time use Spring Framework at run time.
Hope this helps.
I do not want to be rude, but also from SO tags we know:
spring
The Spring Framework is an open source framework for application development on the Java platform. At its core is rich support for component based architectures, and it currently has over a dozen highly integrated modules.

spring-mvc
Based on the Model-View-Controller (MVC) pattern, Spring MVC helps you build web-based applications that are flexible and decoupled from the underlying view technologies.

Spring Roo is a lightweight tool aimed at developer productivity. Via an intuitive command line interface it supports operations such as Java web project creation, persistence configuration and view scaffolding. Roo creates a Java web project that uses the Spring framework, and leverage some best ...

My own brief description would be: Spring framework is the framework providing some functionalities for example dependency injection. Spring MVC is for creating web projects as you mentioned already. Finally Spring Roo is a tool, that helps you increase productivity, I'd say that instead of manual configuration changes you are using this tool.
Hopefully, this was not too brief...
