Calling Azure Migrate Rest Api Using Azure SDK for Java

Question

I am trying to Make PUT request to craete project in azure migrate with spring boot .Previously i was doing with Rest Template. Like @Autowire RestTemplate template;

HttpHeaders headers = new HttpHeaders(); headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

    MultiValueMap<String, String> map = new LinkedMultiValueMap<>();
    map.add("grant_type", assessment.getGrant_type());
    map.add("client_id", assessment.getClient_id());
    map.add("client_secret", assessment.getClient_secret());
    map.add("code", authToken);

    HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<MultiValueMap<String, String>>(map, headers);
    ResponseEntity<String> response = restTemplate.exchange(baseUrl, HttpMethod.POST, request, String.class);

authToken i am getting making separate GET call to Authentication URL previous to POST call and setting in POST header.

I am posting partial code so that you can get an idea what i am doing.

Now i have been asked to use Azure-sdk for java to write the same code. I need not to use Rest Template.Can anybody tell me how can i make POST call using Azure-sdk for java classes.I search on google and you tube but nothing concrete found.

If you want to use Azure java sdk to call Azure rest API, please refer to the following code

a. create a service principal (I use Azure CLI to do that)

az login
az account set --subscription "<your subscription id>"
# the sp will have Azure Contributor role
az ad sp create-for-rbac -n "readMetric"

Install sdk

<!-- https://mvnrepository.com/artifact/com.microsoft.azure/azure -->
<dependency>
    <groupId>com.microsoft.azure</groupId>
    <artifactId>azure</artifactId>
    <version>1.33.0</version>
</dependency>

Code

 private static String tenantId="hanxia.onmicrosoft.com"; // sp tenant
    private static String clientId = "42e0d080-b1f3-40cf-8db6-c4c522d988c4"; // sp appid

    private static String clientKey = "Gbx*************JDfQpIjoae:";// sp password
    private static String subscriptionId="e5b0fcfa-e859-43f3-8d84-5e5fe29f4c68"; //sp subscription id

ApplicationTokenCredentials creds = new
                ApplicationTokenCredentials(clientId,tenantId,clientKey, AzureEnvironment.AZURE);

        RestClient restClient =new RestClient.Builder()
                .withBaseUrl(AzureEnvironment.AZURE, AzureEnvironment.Endpoint.RESOURCE_MANAGER)
                .withSerializerAdapter(new AzureJacksonAdapter())
                .withReadTimeout(150, TimeUnit.SECONDS)
                .withLogLevel(LogLevel.BODY)
                .withResponseBuilderFactory(new AzureResponseBuilder.Factory())
                .withCredentials(creds)
                .build();
        OkHttpClient httpClient = restClient.httpClient().newBuilder().build();
        String url="https://management.azure.com/subscriptions/"+subscriptionId+"/providers/Microsoft.Migrate/projects?api-version=2018-02-02";
        Request request = new Request.Builder()
                              .url(url)
                              .method("get",null)
                              .build();
        Response response1 = httpClient.newCall(request).execute();
        if(response1.isSuccessful()){

            System.out.println(response1.headers().toString());

        }
