What is the difference between these Spring Boot jars.
spring-boot-starter-data-mongodb jar
spring-data-mongodb jar
mongodb-driver jar
mongodb-driver-core jar
What I understand in those all is that mongodb-driver is the java driver for mongoDB. And spring-boot-starter-data-mongodb is starter like spring boot has for many (spring-boot-starter-web, spring-boot-starter-test).
Can someone please explain their role in Spring boot.
mongodb-driver-core: The Java operations layer for the MongoDB Java Driver. Third parties can ' + 'wrap this layer to provide custom higher-level APIs.
mongodb-driver: The driver which allows you to connect to MongoDB databases from java applications.
spring-data-mongodb: The library you need to use Spring Data with MongoDB in your project, which might not be Spring Boot based.
spring-boot-starter-data-mongodb: The starter for using Spring Data Mongo DB in Spring Boot, with everything you need for that.
Note that each of these libraries makes use of the other ones above, so it increases abstraction.

I tried to migrate the springboot application to the Dropwizard. However, I now have a problem that there is no framework in the Dropwizard that supports working with Cassandra databases, such as CRUD operations. Do any of you have any good suggestions?

Difference between Spring MVC and Spring Boot [closed]

Closed 4 years ago.
I want to ask about Spring Boot and Spring MVC.
What is the difference between these components and when should I use them?
How can I use Spring MVC to generate entities from a database?
You can use spring boot to embed a web server into your JAR. So basically you can run a single command (e.g. java -jar yourSpringBoot.jar) and it will start up the embedded web server and listen on whatever port you configured in the application properties file. Spring MVC is a framework, it allows you to build web applications.
For the database question, I would recommend reading about Hibernate and its spring boot integration.
Spring Boot is a framework for running enterprise applications using a simple, all-in-one tool that can configure, build, and run an application.
Spring MVC is a framework for building said application. It is used to create Web application API endpoints, visualizations, database entities, and other stuff. You can configure and run it with Spring Boot or just use the standard Spring configuration system.
If you want to map entities to a database, you can use Spring MVC and Spring Boot. There are plenty of tutorials online, but the basics is like this:
Create a Plain Old Java class with getters and setters (methods like getXXX and setXXX).
Annotate the class with #Entity
Ensure that Spring recognizes that package as containing entities. This can be done with Spring Boot by default when you annotate your Application class with #EnableAutoConfiguration

I have a Spring Boot application that uses Spring Batch. I want now to implement an admin panel to see all job statuses. For this, Spring has "spring-batch-admin" But I see that is deprecated long time ago:
The functionality of Spring Batch Admin has been mostly duplicated
and
expanded upon via Spring Cloud Data Flow and we encourage all users to
migrate to that going forward.
But then Spring Cloud Data Flow says:
Pipelines consist of Spring Boot apps, built using the Spring Cloud
Stream or Spring Cloud Task microservice frameworks
So in order to use this functionality do I really need to convert my spring boot app to a microservice? Isn't this an overkill just to see some batch statuses? Also I can not install docker on my production server(for various reasons) Can I still use Spring Cloud Data Flow without docker?
Yes, spring boot batch should be wrapped as spring cloud task, which should not be too complicated.
If Docker does not suit your needs - https://docs.spring.io/spring-cloud-dataflow/docs/current/reference/htmlsingle/#getting-started-local-deploying-spring-cloud-dataflow
Update
Sorry for not being clear in my question, I am developing a Spring project with the next dependencies
Spring Boot
Spring Data
Mysql
wsdl
In the project I exposed soap Web services with Spring Data for persistence, I have to use RMI for support of application desktop.
I tried the following :
Integrate in the same project Spring and RMI (using RMI Register ) successfully but when I tried use Spring annotations obviously not working.
I'm searching when I found that Spring have support for RMI using XML configuration but I need the configuration in annotations.
My question How to would implement RMI in my project?
I'm using latest version in all dependencies
I've created a "framework/toolkit" for a specific type of database search. This was done with Spring-Data JPA using hibernate. This framework is usable by standalone desktop app or as a web application.
This framework ships with entity classes, Spring-Data Repositories and a transactional Service layer with optional method level security (spring-security annotations).
now I would like to create a web application using this framework. Since grails is from spring to and also uses hibernate I thought this might work but I'm open to other suggestions.
The entities in the web application will extend such provided by my framework and should use spring-data repositories extending repositories provided by the framework and services extending provided services for data access.
Or said otherwise I'm mainly interested in the scaffolding part (controller and CRUD web pages) and not the data access part. I'm open to any other tools that can achieve this.
Is this possible with grails? Other suggestions? Spring Roo?
