Spring Boot is built on the top of the spring and contains all the features of spring. And is becoming a favorite of developers these days because of its rapid production-ready environment which enables the developers to directly focus on the logic instead of struggling with the configuration and setup. Spring Boot is a microservice-based framework and making a production-ready application in it takes very little time.
However...Both hibernate and spring are hot and you will find them in all job requirements posted for enterprise applications- so you are on the right track as far as your selection choices is concerned.

If I was the hiring manager and were using hibnernate and SpringI would rather take someone who was stronger on Hibernate rather than someone who was stronger on SpringAs far as spring is concerned- you as a contributing programmer- will have little to worry aboutMost likely the application will already have a framework in place- and you will have to plug in your contributions in.
the same here, I learned hibernate first and than Spring, i think it is the right order,do some small examples from youtube, see how you configure hibernate, create a session and do some tricks with your database, at least basic stuff.then go and see how to configure spring with hibernate.
Notice that this is the only place where we are using Hibernate related classes. This pattern makes our implementation flexible and easy to migrate from one technology to another. For example, if we want to use iBatis ORM framework, all we need is to provide a DAO implementation for iBatis and then change the spring bean configuration file. In above example, I am using Hibernate session transaction management. But we can also use Spring declarative transaction management using Transactional annotation, read more at Spring Transaction Management.
Change the spring bean configuration file, till now you must have figured out that Spring bean configuration file is the key for integration of spring and hibernate framework. Below spring bean configuration file will work for Spring 4 and Hibernate 4 versions.
For hibernate 4, we need to use org.springframework.orm.hibernate4.LocalSessionFactoryBean for SessionFactory bean, Spring ORM has merged both the classes for Hibernate 3 and there is a single class now, this is good to avoid confusion. All the other configurations are same as before.
Spring Kotlin support is documented in the Spring Framework and Spring Boot reference documentation. If you need help, search or ask questions with the spring and kotlin tags on StackOverflow or come discuss in the #spring channel of Kotlin Slack.
In addition to the obvious Kotlin Gradle plugin, the default configuration declares the kotlin-spring plugin which automatically opens classes and methods (unlike in Java, the default qualifier is final in Kotlin) annotated or meta-annotated with Spring annotations. This is useful to be able to create Configuration or Transactional beans without having to add the open qualifier required by CGLIB proxies for example.
Although Java does not allow one to express null-safety in its type-system, Spring Framework provides null-safety of the whole Spring Framework API via tooling-friendly annotations declared in the org.springframework.lang package. By default, types from Java APIs used in Kotlin are recognized as platform types for which null-checks are relaxed. Kotlin support for JSR 305 annotations + Spring nullability annotations provide null-safety for the whole Spring Framework API to Kotlin developers, with the advantage of dealing with null related issues at compile time.
In addition to the obvious Kotlin Maven plugin, the default configuration declares the kotlin-spring plugin which automatically opens classes and methods (unlike in Java, the default qualifier is final in Kotlin) annotated or meta-annotated with Spring annotations. This is useful to be able to create Configuration or Transactional beans without having to add the open qualifier required by CGLIB proxies for example.
Notice that we are using here a Kotlin extension that allows to add Kotlin functions or operators to existing Spring types. Here we import the org.springframework.ui.set extension function in order to be able to write model["title"] = "Blog" instead of model.addAttribute("title", "Blog"). The Spring Framework KDoc API lists all the Kotlin extensions provided to enrich the Java API.
Learn the Spring basics.Spring Boot builds on many other Spring projects.Check the spring.io web-site for a wealth of reference documentation.If you are starting out with Spring, try one of the guides.
You can use Spring Boot in the same way as any standard Java library.To do so, include the appropriate spring-boot-*.jar files on your classpath.Spring Boot does not require any special tools integration, so you can use any IDE or text editor.Also, there is nothing special about a Spring Boot application, so you can run and debug a Spring Boot application as you would any other Java program.
Once downloaded, follow the INSTALL.txt instructions from the unpacked archive.In summary, there is a spring script (spring.bat for Windows) in a bin/ directory in the .zip file.Alternatively, you can use java -jar with the .jar file (the script helps you to be sure that the classpath is set correctly).
The Spring Boot CLI includes scripts that provide command completion for the BASH and zsh shells.You can source the script (also named spring) in any shell or put it in your personal or system-wide bash completion initialization.On a Debian system, the system-wide scripts are in /shell-completion/bash and all scripts in that directory are executed when a new shell starts.For example, to run the script manually if you have installed by using SDKMAN!, use the following commands:
You can shortcut the steps below by going to start.spring.io and choosing the "Web" starter from the dependencies searcher.Doing so generates a new project structure so that you can start coding right away.Check the start.spring.io user guide for more details.
The mvn dependency:tree command prints a tree representation of your project dependencies.You can see that spring-boot-starter-parent provides no dependencies by itself.To add the necessary dependencies, edit your pom.xml and add the spring-boot-starter-web dependency immediately below the parent section:
The gradle dependencies command prints a tree representation of your project dependencies.Right now, the project has no dependencies.To add the necessary dependencies, edit your build.gradle and add the spring-boot-starter-web dependency in the dependencies section:
At this point, your application should work.Since you used the spring-boot-starter-parent POM, you have a useful run goal that you can use to start the application.Type mvn spring-boot:run from the root project directory to start the application.You should see output similar to the following:
At this point, your application should work.Since you used the org.springframework.boot Gradle plugin, you have a useful bootRun goal that you can use to start the application.Type gradle bootRun from the root project directory to start the application.You should see output similar to the following:
The curated list contains all the Spring modules that you can use with Spring Boot as well as a refined list of third party libraries.The list is available as a standard Bills of Materials (spring-boot-dependencies) that can be used with both Maven and Gradle.
Starters are a set of convenient dependency descriptors that you can include in your application.You get a one-stop shop for all the Spring and related technologies that you need without having to hunt through sample code and copy-paste loads of dependency descriptors.For example, if you want to get started using Spring and JPA for database access, include the spring-boot-starter-data-jpa dependency in your project.
If the class is not on the classpath, you can use the excludeName attribute of the annotation and specify the fully qualified name instead.If you prefer to use EnableAutoConfiguration rather than SpringBootApplication, exclude and excludeName are also available.Finally, you can also control the list of auto-configuration classes to exclude by using the spring.autoconfigure.exclude property.
The Spring Boot Gradle plugin also includes a bootRun task that can be used to run your application in an exploded form.The bootRun task is added whenever you apply the org.springframework.boot and java plugins and is shown in the following example:
Spring Boot includes an additional set of tools that can make the application development experience a little more pleasant.The spring-boot-devtools module can be included in any project to provide additional development-time features.To include devtools support, add the module dependency to your build, as shown in the following listings for Maven and Gradle:
While caching is very beneficial in production, it can be counter-productive during development, preventing you from seeing the changes you just made in your application.For this reason, spring-boot-devtools disables the caching options by default.
Cache options are usually configured by settings in your application.properties file.For example, Thymeleaf offers the spring.thymeleaf.cache property.Rather than needing to set these properties manually, the spring-boot-devtools module automatically applies sensible development-time configuration.
