Spring Boot for Microservices: New Microservices & Resilience
In this lesson, we'll be talking about microservice resilience and the creation of new microservices with Spring.
We'll cover the following
New microservices#
Creating a new microservice is very easy with Spring Boot. A build script and a main class are enough, as shown in the example simplest-spring-boot.
To further simplify the creation of a new microservice, a template can be created. The template only needs to be adapted for a new microservice.
Settings for the configuration of the microservices or for logging can be defined in the template.
Thus, a template simplifies the creation of new microservices and facilitates compliance with macro architecture rules.
A particularly easy way to create a new Spring Boot project is to use http://start.spring.io/.
The developer must select the build tool, the programming language, and a Spring Boot version.
In addition, they can select different starters. Based on this, the website then creates a project that can be the basis for the implementation of a microservice.
Resilience#
For resilience, a library like Hystrix can be useful.
Hystrix implements typical resilience patterns such as timeouts in Java. Spring Cloud offers an integration and further simplification for Hystrix.
