Spring, Boot and Microservices – the latest
Spring is a very popular open source framework that’s used by tens of thousands of developers worldwide. It provides a comprehensive infrastructure and lots of useful out-of-the box modules, which greatly simplify the development of Java applications in the enterprise.
This drastically reduces development time and helps explain why Spring is so popular with microservice developers. They particularly like features such as dependency injection, Spring access-orientated programming (AOP), REST API creation and data access via Spring JDBC.
Take data access as an example of the benefits that Spring can bring. In the past, a lot of boilerplate code would have been needed to insert a record into a data source. These days, by using a template in the Spring JDBC module, that can be reduced to a few lines of code with just a few configurations – which obviously speeds things up.
Faster development with Spring Boot
Spring Boot, though, can get applications into production even more quickly. It’s an extension of the Spring framework that minimises the upfront configuration of Spring. By taking an opinionated view of starter dependencies, Spring Boot greatly simplifies the configuration and build process.
For example, Spring Boot – unlike Spring – only needs one dependency to get a web application up and running. All the other dependencies are added automatically during build time. Similarly, for MVC configuration, Spring Boot only requires a few properties once the Boot web starter has been added. All the Spring configuration is automatically included though the auto-configuration process.
Spring Boot, therefore, makes it easier to create a self-contained, production-grade microservice application that can be ‘just run’. Production-ready features include metrics, tracing and health checks. An embedded server also helps to reduce complexity when deploying the application across the enterprise.
The trend for microservices
Microservice architecture is a popular way to build and scale large applications, with 92% of respondents in a recent survey saying they had increased the number of their microservices in the last year. The same number expected to grow their use in the coming year. Speed of development, agility and scalability are key benefits of the approach – and these are important considerations now and in the future.
When it comes to the actual coding, Java is the most popular language in 2019, according to the TIOBE Index. The reasons for this include its stability and maturity – as well as the presence of established frameworks such as Spring and Spring Boot. They help to simplify coding, speed up development and allow easy movement between systems – which are very compelling reasons to use them.
