Java, Spring Boot, Microservices, Cloud and DevOps Tutorials
Spring framework 6.1 introduced a new JdbcClient API, which is a wrapper on top of JdbcTemplate, for performing database operations using a fluent API.
Spring Boot 3.2 includes Spring framework 6.1, so let’s take a quick look at how we can use JdbcClient to implement various database operations in a simplified manner.
In this Spring Boot REST API Best Practices series, we have learned how to implement CRUD operations so far. In this Part-4, we will explore how to implement exception handling for our APIs.
In this Spring Boot REST API Best Practices - Part-3, we will see how to implement FindById and DeleteById API endpoints.
In this Spring Boot REST API Best Practices - Part-2, I will explain some of the best practices we should follow while implementing Create and Update API endpoints.
In this Spring Boot REST API Best Practices Series, I will explain some of the best practices we should follow while implementing REST APIs. Also, I will explain some of the common mistakes developers do and how to avoid them.
In the previous Spring Boot JdbcTemplate Tutorial we have seen how to initialize database using schema.sql and data.sql scripts. This may be useful for demos and quick prototypes, but for real world applications we should use a database migration tool.
Spring provides a high-level abstraction on top of JDBC with JdbcTemplate to make it easier to perform database operations. Spring also provides a high-level abstraction on top of JPA with Spring Data JPA to make it easy to implement CRUD operations, sorting, pagination, etc.
Spring’s JdbcTemplate provides high-level abstraction on top of DataSource to perform database operations. In addition to that Spring’s declarative Transaction Management capabilities helps to manage database transactions in a simplified way without having to write boilerplate code.
Typically, software applications run in different environments. During development, it will be local, and then we may deploy it on QA, Staging, Performance and finally in Production environments. You may have to configure your application with different configuration properties while running the application in different environments.
Logging is a common and important requirement for running applications in production. Spring Boot provides great support for application logging out of the box and offers various customization options. In this tutorial, you will learn how to implement logging in your Spring Boot application using Logback and Log4j2.
