extends InterceptingHttpAccessor implements RestOperations
The central class for client-side HTTP access. It simplifies communication with HTTP servers, and enforces RESTful principles. It handles HTTP connections, leaving application code to provide URLs (with possible template variables) and extract results.

The main entry points of this template are the methods named after the six main HTTP methods: HTTP methodRestTemplate methods DELETE delete(java.lang.String, java.lang.Object...) GET getForObject(java.lang.String, java.lang.Class<T>, java.lang.Object...) getForEntity(java.lang.String, java.lang.Class<T>, java.lang.Object...) HEAD headForHeaders(java.lang.String, java.lang.Object...) OPTIONS optionsForAllow(java.lang.String, java.lang.Object...) POST postForLocation(java.lang.String, java.lang.Object, java.lang.Object...) postForObject(java.lang.String, java.lang.Object, java.lang.Class<T>, java.lang.Object...) PUT put(java.lang.String, java.lang.Object, java.lang.Object...) any exchange(java.lang.String, org.springframework.http.HttpMethod, org.springframework.http.HttpEntity<?>, java.lang.Class<T>, java.lang.Object...) execute(java.lang.String, org.springframework.http.HttpMethod, org.springframework.web.client.RequestCallback, org.springframework.web.client.ResponseExtractor<T>, java.lang.Object...)

The exchange and execute methods are generalized versions of the more specific methods listed above them. They support additional, less frequently used combinations including support for requests using the HTTP PATCH method. However, note that the underlying HTTP library must also support the desired combination.

For each of these HTTP methods, there are three corresponding Java methods in the RestTemplate . Two variant take a String URI as first argument (eg. getForObject(String, Class, Object[]) , getForObject(String, Class, Map) ), and are capable of substituting any URI templates in that URL using either a String variable arguments array, or a Map<String, String> . The string varargs variant expands the given template variables in order, so that String result = restTemplate.getForObject("http://example.com/hotels/{hotel}/bookings/{booking}", String.class,"42", "21"); will perform a GET on http://example.com/hotels/42/bookings/21 . The map variant expands the template based on variable name, and is therefore more useful when using many variables, or when a single variable is used multiple times. For example: Map<String, String> vars = Collections.singletonMap("hotel", "42"); String result = restTemplate.getForObject("http://example.com/hotels/{hotel}/rooms/{hotel}", String.class, vars); will perform a GET on http://example.com/hotels/42/rooms/42 . Alternatively, there are URI variant methods ( getForObject(URI, Class) ), which do not allow for URI templates, but allow you to reuse a single, expanded URI multiple times.

Furthermore, the String -argument methods assume that the URL String is unencoded. This means that restTemplate.getForObject("http://example.com/hotel list"); will perform a GET on http://example.com/hotel%20list . As a result, any URL passed that is already encoded will be encoded twice (i.e. http://example.com/hotel%20list will become http://example.com/hotel%2520list ). If this behavior is undesirable, use the URI -argument methods, which will not perform any URL encoding.

Objects passed to and returned from these methods are converted to and from HTTP messages by HttpMessageConverter instances. Converters for the main mime types are registered by default, but you can also write your own converter and register it via the messageConverters bean property.

This template uses a SimpleClientHttpRequestFactory and a DefaultResponseErrorHandler as default strategies for creating HTTP connections or handling HTTP errors, respectively. These defaults can be overridden through the requestFactory and errorHandler bean properties.
