What are the most important features of spring boot framework and how spring boot is different from Spring framework?

Spring Boot is a popular Java-based framework that helps developers create standalone, production-grade Spring-based applications quickly and easily. It is built on top of the popular Spring framework and provides several features that make it an ideal choice for modern web development. In this article, we will discuss the most important features of Spring Boot and how it differs from the Spring framework.

Easy Configuration: One of the most significant features of Spring Boot is its ability to provide easy configuration of Spring-based applications. It uses a convention-over-configuration approach to minimize the need for XML configuration files. Instead, Spring Boot uses Java-based configuration files to manage application settings, making it easier to set up and manage complex Spring-based applications.

Embedded Server: Spring Boot comes with an embedded server that allows developers to build and deploy standalone applications without the need for a separate web server. This feature reduces the complexity of deploying Spring-based applications and helps developers get started with their projects quickly.

Auto-configuration: Another essential feature of Spring Boot is auto-configuration. It automatically configures the Spring-based application based on the classpath and provides sensible defaults for common configuration settings. This feature makes it easy to get started with Spring-based applications, and developers can focus on writing business logic instead of spending time configuring the application.

Dependency Management: Spring Boot provides an excellent dependency management system that helps developers manage their project's dependencies easily. It uses a Maven-based approach to manage dependencies and automatically downloads and configures the required libraries, making it easy to keep track of dependencies and avoid conflicts.

Production Ready: Spring Boot is designed to create production-ready applications. It comes with several features that help developers build and deploy applications that are ready for production use. Some of these features include metrics, health checks, and externalized configuration, making it easy to manage and monitor applications in production environments.

Now, let's discuss how Spring Boot differs from the Spring framework.

Configuration: Spring Boot uses a convention-over-configuration approach to minimize the need for XML configuration files, while the Spring framework relies heavily on XML configuration files to manage application settings.

Dependency Management: Spring Boot provides an excellent dependency management system that helps developers manage their project's dependencies easily, while the Spring framework relies on developers to manage dependencies manually.

Auto-configuration: Spring Boot provides auto-configuration, which automatically configures the Spring-based application based on the classpath and provides sensible defaults for common configuration settings, while the Spring framework requires developers to configure their application manually.

Embedded Server: Spring Boot comes with an embedded server that allows developers to build and deploy standalone applications without the need for a separate web server, while the Spring framework requires a separate web server to deploy applications.

Let's conclude it, Spring Boot provides several features that make it an ideal choice for modern web development. Its easy configuration, embedded server, auto-configuration, dependency management, and production-ready features make it a popular choice for developers. While Spring Boot is built on top of the Spring framework, it differs in several ways, including its approach to configuration, dependency management, auto-configuration, and embedded server.

What is version checking in Hibernate ?

Version checking used in hibernate when more then one thread trying to access same data. For example : User A edit the row of the TABLE for update ( In the User Interface changing data This is user thinking time) and in the same time User B edit the same record for update and click the update. Then User A click the Update and update done. Change made by user B is gone. In hibernate you can prevent slate object updation using version checking. Check the version of the row when you are updating the row. Get the version of the row when you are fetching the row of the TABLE for update. On the time of updation just fetch the version number and match with your version number (on the time of fetching).

What are JEE Containers? What are their different types?

Containers are the interface between a component and the low-level, platform-specific functionality that supports the component. Before it can be executed, a web, enterprise bean, or application client component must be assembled into a Java EE module and deployed into its container. The assembly process involves specifying container settings for each component in the Java EE application and for the Java EE application itself. Container settings customize the underlying support provided by the Java EE server, including such services as security, transaction management, Java Naming and Directory Interface (JNDI) API lookups, and remote connectivity. Here are some of the highlights. The Java EE security model lets you configure a web component or enterprise bean so that system resources are accessed only by authorized users. The Java EE transaction model lets you specify relationships among methods that make up a single transaction so that all methods in one transaction are treated as a ...
