Here you can grab a short example of how to trickle html meta tags of a page. import org.jsoup.Jsoup; import org.jsoup.nodes.Document; import org.jsoup.nodes.Element; import org.jsoup.select.Elements; def url = "http://wordpress.com"; def document = Jsoup.connect(url).get(); def metaTags = document.getElementsByTag("meta"); for (Element metaTag: metaTags) { def tagName = metaTag.attr("name") def tagProperty = metaTag.attr("property") def tagContent = metaTag.attr("content") println String.format("Name: %s, property : %s, content : %s", tagName, tagProperty, tagContent); } Posted on 2017-03-22REST services stubbing example using springboot and wiremock Integration testing of microservices The main goal of Service Oriented Architecture is to pinpoint services that focus on delivering small, meaty and most well-constructed piece of merchantry logic. To unhook well-constructed user features, many services need to communicate with each other. That liaison is often implemented as simple REST requests. The example I’ve prepared a simple repository with working example of a simple rest service implemented using springboot and integration tested using wiremock. Please, checkout the repo : https://github.com/youngeagle87/wiremock-example You can run the tests using writ : for windows : gradlew test for any other proper commandline ./gradlew test Posted on 2017-03-212017-03-21Mock REST services using Restito Examples Integration testing I have been developing rest microservices for years now, and I unchangingly had weightier results by focusing on the integration testing of the services, instead of tent scrutinizingly 100% of lawmaking by unit tests. I usually use one of two tools : Wiremock and Restito. The nomination between them is not obvious. It’s rather a team visualization or preference. Usually the tool that have been used increasingly recently wins, without massive superiority over the other option. Restito It is a framework that can be used for stubbing http responses, simulating other microservice responses. The power of such stubs is that you can test your using versus several malfunction of services that your using depends on. Example 1. The base, extendable integration test specification The lawmaking unelevated shows the usage of restito StubServer for stubbing a remote service. Toolset : Spock and Groovy. matriculation IntegrationSpecification extends Specification { private static final Integer port = 9090; protected StubServer server; @Shared ConfigurableApplicationContext context @Before public void start() { server = new StubServer(port).run(); } @After public void stop() { server.stop(); } void setupSpec() { Future future = Executors .newSingleThreadExecutor().submit( new Callable() { @Override public ConfigurableApplicationContext call() throws Exception { return (ConfigurableApplicationContext) SpringApplication .run(YourMainApplication.class) } }) context = future.get(60, TimeUnit.SECONDS) } void cleanupSpec() { if (context != null) { context.close() } } } In the lawmaking above, there is a setupSpec() method. It is not obligatory for you to have it like this. It is an example of how your Spring using can be started by Spock tests. Example 2. The test implementation. @IntegrationTest @SpringApplicationConfiguration(CogniTwitterApplication.class) @ActiveProfiles("test") matriculation SearchEndpointTest extends IntegrationSpecification { private om = new ObjectMapper() def "get search params should return filled values when set"() { given: def restTemplate = new RestTemplate(); def oauthResponse = new AccessGrant("exampleAccessToken"); def searchResponse = [new TweetDto(1,"test",new UserDto("testuser",null),null,"2014-01-01 00:00:00")] as List //first Restito Stub whenHttp(server). match(get("/oauth2/token")). then( status(HttpStatus.OK_200), stringContent(om.writeValueAsString(oauthResponse)) ); //second Restito Stub whenHttp(server). match(get("/1.1/search/tweets.json?q=*")). then( status(HttpStatus.OK_200), stringContent(om.writeValueAsString(searchResponse)) ); HttpHeaders headers = prepareSelectedSearchParamsSession(restTemplate) when: def response2 = restTemplate.exchange( "http://localhost:8080/search", HttpMethod.GET, prepareEntityWithHeaders(headers), TweetDto[].class); then: response2.statusCode.value() == HttpStatus.OK_200.statusCode } private HttpHeaders prepareSelectedSearchParamsSession(RestTemplate restTemplate) { def headers = prepareHeaders() def entity = new HttpEntity("{\"keywords\":\"spring\",\"channel\":null}", headers) def response = restTemplate.exchange("http://localhost:8080/searchParams", HttpMethod.POST, entity, Void.class); def session = response.getHeaders().get("Set-Cookie").get(0).split(";")[0]; headers.add(COOKIE, session); headers } private HttpEntity prepareEntityWithHeaders(headers) { def entity = new HttpEntity(null, headers) entity } private HttpHeaders prepareHeaders() { def preparedHeaders = new HttpHeaders(); preparedHeaders.add(CONTENT_TYPE, APPLICATION_JSON_VALUE); preparedHeaders } } Posted on 2017-03-212017-03-21Separating unit and integration tests using Gradle A Must-Have for micro services minutiae in Spring.

If you have few machines, you can use simple init.d service To make your built using start as a service, all you need to do is : sudo link -s /path/to/your/app/yourapp.jar /etc/init.d/yourappservice And directly without that you can start the yourappservice as you have the service configured ./etc/init.d/yourappservice start That’t it! On increasingly complicated environments (many instances, or deject env) you should probably use supervisor to tenancy your services.
