    • In this project we will consume a REST API and a SOAP web service in our User service repository.

    REST API

    Step 1

    Familiarize yourself with the git api found here https://developer.github.com/v3/ learn which endpoint to get your repo, commits maybe branches etc. Try it out or postman or curl on the terminal

    Step 2

    Now we are going to consume the api in our spring boot application using restTemplates as per topic work. I would like to se

    1. I would like you to specifically return the v3 version of the api (Hint: Read more on how to set headers in RestTemplate)
    2. A list of all your repos - output on the console
    3. A list of commits in 1 repo of your choice - output on teh console

    SOAP WEB SERVICE

    Step 1

    Clone the repo found here https://github.com/spring-guides/gs-producing-web-service and open the complete folder not the entire repo. Review it on a high level this will be the wsdl project we are going to use to learn how to consume a wsdl application. DO NOT ADD THIS PROJECT AS PART OF YOUR SUBMISSION(this is so that you can generate the files)

    Change the application to sun on port 9090 by adding this to the properties file

    server.port=9090

    Run the application you should be able to do to the below url,

    http://localhost:9090/ws/countries.wsdl

    and see this

    <wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:sch="http://spring.io/guides/gs-producing-web-service" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://spring.io/guides/gs-producing-web-service" targetNamespace="http://spring.io/guides/gs-producing-web-service">
    <wsdl:types>
        <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" targetNamespace="http://spring.io/guides/gs-producing-web-service">
        <xs:element name="getCountryRequest">
            <xs:complexType>
            <xs:sequence>

// ....

    keep this project running in the background

    Step 2 In your terminal navigate to YourUserServiceRepo/src/main/java and run this command

    wsimport -keep -p com.nameOfYourPackage.wsdl http://localhost:9090/ws/countries.wsdl

    Step 3

    Now we start to do the real work

    1. Get the currency for United Kingdom: Output
    Currency: GBP
    1. Get the capital of United Kingdom: Output
    Capital: London
    1. Get the population of United Kingdom: Output
    Population: 63705000

    Happy Hacking!!!
