![]() Minimum spare threads will help make sure the number of the minimum threads available when the connector is started and during the idle time.Īs always the code is available in github with a Bonus benchmark results. For example, we can change the max threads and the max minimum spare threads in used by Tomcat ClientHttpRequestFactory createRequestFactory() throws InterruptedException There are a couple of other things to keep in mind. One is using a HttpClient directly another way using the ApacheHttpClientFactory. Let's take a look at the Apache Http Client first.Īpache HttpClient can be created using two ways. The request factory can be created using the ClientHttpRequestFactory in which we can use the HTTP Client of our choice Apache or OkHttp. In order to configure the RestTemplate, we need to set up user-provided request factory instead of the default. Both are solid Http Client implementations used by many projects/libraries with a great community. We can do this either directly or by using Spring Cloud Commons .httpclient which provides ApacheHttpClientFactory and OkHttpClientFactory. We can configure the RestTemplate to use the HttpClient of our choice. In Spring, the default HTTP client can be changed to Apache's HttpClient or Square's OkHttpClient. It is still unclear whether this will be used in Spring clients. We can use this to make a client connection as well without needing third-party libraries. There is a new module added in Java 9 in incubation status and standardized in Java 11 called. It is developed on top of the HttpURLConnection. The default HttpClient used in the RestTemplate is provided by the JDK. It is important to know how we can customize the RestTemplate changing different Http clients. ![]() Majority of the applications in production uses RestTemplates and will be practically a long way before it is completely replaced with Reactive WebFlux. If you read the official documentation carefully, you might read that RestTemplate will be deprecated in the future and we must use WebClient which offers Synchronous, Asynchronous and Streaming scenarios such as Server-Sent Events, WebSockets, etc. If you're a Spring boot user, you might have definitely used RestTemplate. The Spring WebClient API must be used on top of an existing asynchronous HTTP client library. It also contains an HTTP client and the web-related parts of Spring remote support.Ĭentral Alfresco OpenMind Sonatype Spring Releases Spring Web provides integration features such as multipart file upload functionality and the initialization of the IoC container using Servlet listeners ![]()
