![]() ![]() It provides declarative support for caching, validation, transactions and formatting. It provides powerful abstraction to JavaEE specifications such as JMS, JDBC, JPA and JTA. The Dependency Injection feature of Spring Framework and it support to various frameworks makes the easy development of JavaEE application. Secure Spring Boot 3 Application With Keycloak. See the Basic types chapter for more info. The Spring Framework doesn't force the programmer to inherit any class or implement any interface. The Basic annotation is used to map a basic attribute type to a database column. Spring framework is lightweight because of its POJO implementation. The EJB or Struts application require server to run the application but Spring framework doesn't require server. The Dependency Injection makes easier to test the application. The Spring applications are loosely coupled because of dependency injection. You need to write the code of executing query only. ![]() Let's take the example of JdbcTemplate, you don't need to write the code for exception handling, creating connection, creating statement, committing transaction, closing connection etc. ![]() It hides the basic steps of these technologies. So there is no need to write too much code. Spring framework provides templates for JDBC, Hibernate, JPA etc. They are as follows: 1) Predefined Templates There are many advantages of Spring Framework. makes the code loosely coupled so easy to maintain.We provide metadata to the IOC container either by XML file or annotation. In Spring framework, IOC container is responsible to inject the dependency. In such case, there is no need to modify the code if our logic is moved to new environment. Thus, IOC makes the code loosely coupled. Let's understand this with the following code: One of the core benefits of Spring is that it takes care of most of the low-level aspects of building the application to allow us to actually focus on features and business logic. They make the code easier to test and maintain. The Spring Framework is a mature, powerful and highly flexible framework focused on building web applications in Java. These are the design patterns that are used to remove dependency from the programming code. Inversion Of Control (IOC) and Dependency Injection Let's understand the IOC and Dependency Injection first. We will learn these modules in next page. The Spring framework comprises several modules such as IOC, AOP, DAO, Context, ORM, WEB MVC etc. The framework, in broader sense, can be defined as a structure where we find solution of the various technical problems. It can be thought of as a framework of frameworks because it provides support to various frameworks such as Struts, Hibernate, Tapestry, EJB, JSF, etc. It is helpful for beginners and experienced persons. Spring framework makes the easy development of JavaEE application. The following spring-boot-starter-parent inherits automatically when we configure the project.This spring tutorial provides in-depth concepts of Spring Framework with simplified examples. Dependencies, inherited from the spring-boot-dependencies POM.It ignores the tag for that dependencies. It manages the version of common dependencies. It inherits a Dependency Section from the spring-boot-dependency-pom.The Maven project inherits the following features from spring-boot-starter-parent: Note: Spring Boot also allows overriding of dependencies version, if required. We only need to write a library name with specifying the version.It avoids mismatch of different versions of Spring Boot libraries.It helps when we switch from one version to another. It provides the centralization of dependency information by specifying the Spring Boot version in one place.Spring Boot upgrades all dependencies automatically in a consistent way when we update the Spring Boot version. So, we need not to specify the version of the dependencies in our configuration. The list of dependencies is available as a part of the Bills of Materials (spring-boot-dependencies) that can be used with Maven. Each release of Spring Boot provides a list of dependencies that it supports. Spring Boot manages dependencies and configuration automatically. Next → ← prev Spring Boot Dependency Management ![]()
