Spring Boot Tutorial

Recently, we have introduced light-spring-boot repository with two light-4j modules to inject light-4j middleware handlers into the Spring Boot application with embedded Undertow Servlet or embedded Undertow core. The injection is happening at the http core level so these handlers will have much better performance

In most cases, you have already built the Spring Boot application and you want to leverage the Light ecosystem and numeric middleware handlers. If you are starting a brand new project, it is highly recommended using light-rest-4j directly.

Spring Boot Servlet

In this tutorial, we are going to generate a typical Spring Boot application from https://start.spring.io/ and modify it to inject light-4j middleware handlers. The final application can be found at https://github.com/networknt/light-example-4j/tree/master/springboot/servlet Light-4j encourages a design driven approach and it loads the specification during the runtime to validate the request and verify the JWT token scopes based on the specification. For this example application, the specification can be found at https://github.com/networknt/model-config/blob/master/rest/springboot/servlet/openapi.yaml Read More »
