org.springframework.web.client.RestTemplate
public class RestTemplate
Spring's 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:
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 variants 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.
The default set of converters are listed in the following table, and are registered based on the corresponding rule.
| Message Body Converter | Rule |
|---|---|
ByteArrayHttpMessageConverter | Always included |
StringHttpMessageConverter | |
ResourceHttpMessageConverter | |
SourceHttpMessageConverter | |
AllEncompassingFormHttpMessageConverter | |
SimpleXmlHttpMessageConverter | Included if the Simple XML serializer is present. |
MappingJackson2HttpMessageConverter | Included if the Jackson 2.x JSON processor is present. |
GsonHttpMessageConverter | Included if Gson is present, and only included if Jackson is not available. |
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 properties.
