I am working on the web service project by Spring Boot, services exist in a jar,
My question is how to consume these services?
Any help is very appreciated.
(according to your tags, you've developed REST services.)
Postman is a great tool (great GUI with many functionalities) to test your REST services.
It's available as Chrome Extension or as stand alone app.

We are going to developing a web application using the Spring boot framework. Now, we are an architect for how to build a system. Our team members asked questions like when we load our libraries into the spring boot framework then the application is getting overloaded?
Please help me. Is the application is overloaded or not?
I am looking for sample RESTFull application, that can be deployed in Webpshere Application Server 9.x. Posting here with great hope after exhaustive search. Any help much appreciated
There are many samples, here you have two, they are for WebSphere Liberty, but the main concepts and code is the same:
OpenLiberty /sample-restful-webservice
Creating a RESTful web service
There is no need to use Jersey, just use JAX-RS api provided by container.
Bit confused with Spring framework and what capabilities application server provides.
I was reading this answer on same site
There he says,
Additionally App Server have components and features to support
Application level services such as Connection Pooling, Object Pooling,
Transaction Support, Messaging services etc.
That means we can optionally use apis of application server to manage transaction in our web application (inject web application :()and I think spring also provides transaction apis. So whats the difference?
Please, help me to make it clear. Thanks you.
When you use app server resources (transactions, connection pools etc.) directly in your application code, you can only run it when it is deployed on an application server or even worse only on that syme type of application server.
Spring allows you to use those resources and configure your application for different environments. The application can be run on any application server or on a simple Tomcat, or on different servers in the cloud.
Spring also allows you to run your code in tests (unit tests) without the need to start up an application server. This is absolutely needed to write automated tests.
Everything that can be done with an application server, can be done with spring as well.
There is a whole world of spring libraries and framework that provide features that are not available directly on application servers.
I can really recomand to give spring a try.....
Everything I found on the internet about Spring Cloud Netflix is about running microservices from Boot applications using #EnableEurekaClients and so on.
Now I'm trying to connect my logging microservice within a traditional war application (springmvc, jaxws etc) - piece of legacy which can not be converted to Boot or modified in any way (by technical task).
I've created a new maven module "log-server-client" that knows nothing about upper web layer and intended to be used as a simple dependency in any maven project.
How should I configure access to Spring Cloud Netflix for this simple dependency? At least, how to configure Eureka and Ribbon?
I just extracted some lines of code from RestTemplate and created my custom JmsTemplate (microservice works with jms remoting with apache camel and activemq), exactly how it is done in RestTemplate, but this code stil lacks connection to infrastructure
afaik, we can create a global singleton bean, run a separate thread from this bean, and run Boot app from this thread, but don't you think that it is very ugly and can lead to problems? How it really should be used?
Great question!
One approach is to use a "sidecar". This seems to be a companion Spring Boot application that registers with the Eureka Server on behalf of your traditional web app.
See e.g.:
http://www.java-allandsundry.com/2015/09/spring-cloud-sidecar.html
http://cloud.spring.io/spring-cloud-netflix/spring-cloud-netflix.html#_polyglot_support_with_sidecar
Another approach is to use the following library:
"A small lib to allow registration of legacy applications in Eureka service discovery."
https://github.com/sawano/eureka-legacy-registrar
This library can be used outside of Spring Boot.
I want to integrate my spring (3.0) application with Mule ESB (Mule3) and make available those service for different clients (.Net, GWT etc). For accomplish this, whether I should deploy my Spring application as separate component and define Endpoint on Mule or I can deploy my spring application inside the Mule and provide those services to outside clients. If anyone know some ideas or any sample reference projects related to this problem, can please update me. Thanks.
I would recommend integrating Mule into your Spring application. That is, adding the Mule jar files to your app and using it as a library. Doing it this way Mule adds a child context to your main Spring application context and has access to your beans so they can be used as services.
The Using Mule with Spring and Spring Application Contexts pages are the places to start learning about how to do this.
