I'm developing a REST service using JAX-RS and Java 8 and Tomcat 8.I already configuration using {springconfig}.xml. I want to know how to use Spring in Jax-rs web service for controller.I'm looking for answer.

I would like to add a RESTful API using Spring Boot to an existing webapp running on Tomcat. I have tried to use the SpringBootServletInitializer in order simplify the integration. However, when doing so Spring Boot seems to interfere with the existing webapp (e.g., / doesn't work as it used to any more).
Is it possible somehow to configure the Spring Boot integration so that it only handles endpoints that starts with /api and ignores everything else?
Also, is it possible to use the SpringBootServletInitializer for this?
The existing servlets are registered with servlet-mappings using the web.xml file.
I want to a deploy Spring Cloud Gateway but it is built on Spring Framework 5, Project Reactor.
Can I create a WAR file and deploy it on a traditional application server such as Jboss or Tomcat.
The Spring documentation in this page says it is possible.
Spring WebFlux is supported on Tomcat, Jetty, Servlet 3.1+ containers
Note:
this is Spring Cloud Gateway project link
https://spring.io/projects/spring-cloud-gateway
I don't think this is possible, as Spring Cloud Gateway is itself a Spring Boot WebFlux application and this use case is only supported with embedded servers, as mentioned in the Spring Boot reference documentation.
I was looking to implement RestFul Web Services using Spring so in all Spring Projects list I saw Spring Web Services.
But Strangely it's just for SOAP and no Restful web services!
Where is project for RestFul web Services? Is there any JAX-RS implementation of Restful Web Services?
( Actually, It should be part of Spring Web Services project as its a popular web Services architecture as SOAP itself)
For Creating ReSTful web using spring, two ways are there :
1.One very easy way to use Spring MVC project. Spring provides annotations specificto ReSTful web services if you are using Spring MVC project like #RestController etc.
2.One can also create ReSTful web services by following JAX-RS methodology. Using spring-boot-starter-jersey project. Using this one can get other core functionalities of spring framework like DI, AOP etc.
I have a Spring web application - which doesn't use Spring-based GUI, but Wicket - and I would like to build contract-first REST services.
I already have a contract defined in Swagger and I generate model and API artifacts. Swagger codegen generates either Spring Boot artifacts, or Spring MVC ones.
My intention is to use ideally just a model, and maybe API (controllers) from this generated code. But up to my knowledge/research, there is no simple way to have just simple REST service without MVC/Boot boilerplate.
Therefore my questions are:
Is it possible to build lightweight Spring-based REST service, without having "heavy" dependency of full Spring MVC/Spring Boot?
If not, which approach is more lightweight? Spring Boot, or Spring MVC?
You are misinterpreting the Spring ecosystem.
Spring MVC is THE rest web and web service library within Spring portfolio.
The same way as Spring-WS is THE soap web service library.
They are very similar in architecture and style of use.
The fact that Spring MVC is bundled with Spring Framework does not change the situation.
Spring Boot does not bring any new REST offering. It is just a bootstrap mechanism to start Java web server with web app already deployed from a plain main() method. Therefore if you see "Building REST web services with Spring Boot", it just means that it is Spring MVC bootstrapped by Spring Boot.
Therefore, the question to what is more lightweight is straightforward: Spring MVC.
To answer the question #2:
The usage of Spring MVC is more lighweight, then usage of Spring Boot:
Size of the WAR archive:
6,1 MB for Spring MVC
9,2 MB for Spring Boot
Number of libraries in WAR archive:
12 for Spring MVC
28 for Spring Boot
I am a c++ and C# developer. I would like to try use jersey + jetty to create restful web services. I am wondering what does jersey gives in additional to just using JAX-RS library from java? Does the XML declarative web service count?
