What is spring boot and why it is used?
Spring Boot is an open source Java-based framework used to create a micro Service.
It is developed by Pivotal Team and is used to build stand-alone and production ready spring applications.
This chapter will give you an introduction to Spring Boot and familiarizes you with its basic concepts..
What is JPA and Spring Data JPA?
Java Persistence API (JPA) is a specification provided by Java for APIs accessing various SQL databases. … Spring Data JPA is a sub-project of Spring Data and provides abstraction over the Data Access Layer using Java Persistence API and ORM implementations like Hibernate.
Is JPA an ORM?
By itself, JPA is not a tool or framework; rather, it defines a set of concepts that can be implemented by any tool or framework. While JPA’s object-relational mapping (ORM) model was originally based on Hibernate, it has since evolved.
Which is better JPA or JDBC?
JDBC is a low level standard for interaction with databases. JPA is higher level standard for the same purpose. JPA allows you to use an object model in your application which can make your life much easier. JDBC allows you to do more things with the Database directly, but it requires more attention.
What are JPA repositories?
The Java Persistence API (JPA) is the standard way of persisting Java objects into relational databases. The JPA consists of two parts: a mapping subsystem to map classes onto relational tables as well as an EntityManager API to access the objects, define and execute queries, and more.

Is spring a Java boot?
Spring Boot is an open source Java-based framework used to create a Micro Service. It is developed by Pivotal Team. … Spring Boot contains a comprehensive infrastructure support for developing a micro service and enables you to develop enterprise-ready applications that you can “just run”.
Why spring boot is good for Microservices?
Spring Boot enables building production-ready applications quickly and provides non-functional features: Embedded servers which are easy to deploy with the containers. It helps in monitoring the multiples components. It helps in configuring the components externally.
Is JPA faster than JDBC?
It shows that JPA queries are 15% faster than their equivalent JDBC queries. Also, JPA criteria queries are as fast as JPQL queries, and JPA native queries have the same efficiency as JPQL queries.
What is @repository in spring?
@Repository is a Spring annotation that indicates that the decorated class is a repository. A repository is a mechanism for encapsulating storage, retrieval, and search behavior which emulates a collection of objects.
What is the full form of JPA?
JPA is an abbreviation that stands for Java Persistence API. It’s a specification which is part of Java EE and defines an API for object-relational mappings and for managing persistent objects. You can use this API in Java SE and Java EE environments.
What is autoconfiguration in spring?
Simply put, the Spring Boot autoconfiguration represents a way to automatically configure a Spring application based on the dependencies that are present on the classpath. This can make development faster and easier by eliminating the need for defining certain beans that are included in the auto-configuration classes.
Which database is best for spring boot?
MongoDB is an open-source NoSQL document database that uses a JSON-like schema instead of traditional table-based relational data. Spring Boot offers several conveniences for working with MongoDB, including the spring-boot-starter-data-mongodb ‘Starter’.
Is Spring Data JPA an ORM?
Hibernate is a JPA implementation, while Spring Data JPA is a JPA Data Access Abstraction. Hibernate provides a reference implementation of the Java Persistence API that makes it a great choice as an ORM tool with benefits of loose coupling. …

What is JPA spring boot?
Spring Boot JPA is a Java specification for managing relational data in Java applications. It allows us to access and persist data between Java object/ class and relational database. JPA follows Object-Relation Mapping (ORM). … The Java Persistence API.
What is Spring JPA?
Spring Data JPA API provides JpaTemplate class to integrate spring application with JPA. JPA (Java Persistent API) is the sun specification for persisting objects in the enterprise application. It is currently used as the replacement for complex entity beans.
How does Spring Boot define DataSource?
Spring boot allows defining datasource configuration in both ways i.e. Java config and properties config. DataSourceAutoConfiguration checks for DataSource. class (or EmbeddedDatabaseType. class) on the classpath and few other things before configuring a DataSource bean for us.
