org.springframework.web.client RestTemplate. Javadoc. Synchronous client to perform HTTP requests, exposing a simple, template method API over underlying HTTP client libraries such as the JDK HttpURLConnection, Apache HttpComponents, and others.
2019年5月29日 1.环境搭建. 为了演示RestTemplate的使用，我们创建两个SpringBoot项目，一个 provider作为server端，一个consumer作为服务调用方法
For example, The method GetForObject
is the central class within the Spring framework for executing synchronous HTTP requests on the client side. Like Spring JdbcTemplate, RestTemplate. RestTemplate. is also a high-level API, which in turn is based on an HTTP client. By default, the class. java.net.HttpURLConnection. RestTemplate provides higher level methods that correspond to each of the six main HTTP methods that make invoking many RESTful services a one-liner and enforce REST best practices.
RestTemplate public RestTemplate(boolean includeDefaultConverters) Create a new instance of RestTemplate. For performance purposes, no message body converters are registered when using the default constructor. However, this constructor allows you to specify whether to include a default set of converters, which are listed in the RestTemplate javadoc.
The RestTemplate class in Spring Framework is a synchronous HTTP client for making HTTP requests to consume RESTful web services. It exposes a simple and easy-to-use template method API for sending an HTTP request and also handling the HTTP response.
RestTemplate is superior to the HTTP client and takes care of the transformation from JSON or XML to Java objects. The HTTP client, on the other hand, takes care of all low-level details of communication via HTTP. In addition to Apache HttpComponents, other HTTP clients such as OkHttp or Netty can also be used in the RestTemplate substructure.
