org.springframework.web.client.RestTemplate
public class RestTemplate
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:
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. For performance purposes, no converters are registered when using the default
constructor. When you create a new RestTemplate instance, you can then select and customize which converters to
register. This is accomplished via the messageConverters
bean property. You can also
write your own converter and register it the same way.
Alternate constructors allow you to specify whether to include a default set of converters for the main mime types. These 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 | Included on Android 2.2 (Froyo) or newer,
where Source is available. |
XmlAwareFormHttpMessageConverter | |
FormHttpMessageConverter | Included on Android 2.1 (Eclair) and older. |
SimpleXmlHttpMessageConverter | Included if the Simple XML serializer is present. |
MappingJacksonHttpMessageConverter | Included if the Jackson JSON processor is present. |
SyndFeedHttpMessageConverter | Included if the Android ROME Feed Reader is present. |
This template uses a HttpComponentsClientHttpRequestFactory
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.
