From a Spring point of view, none of the <code>HttpMessageConverter</code> instances registered with the <code>RestTemplate</code> can convert <code>text/html</code> content to a <code>ProductList</code> object. The method of interest is <code>HttpMessageConverter#canRead(Class, MediaType)</code>. The implementation for all of the above returns <code>false</code>, including <code>Jaxb2RootElementHttpMessageConverter</code>. 

Since no <code>HttpMessageConverter</code> can read your HTTP response, processing fails with an exception.

If you can control the server response, modify it to set the <code>Content-type</code> to <code>application/xml</code>, <code>text/xml</code>, or something matching <code>application/*+xml</code>.

If you don't control the server response, you'll need to write and register your own <code>HttpMessageConverter</code> (which can extend the Spring classes, see <code>AbstractXmlHttpMessageConverter</code> and its sub classes) that can read and convert <code>text/html</code>.

You can make up a class, RestTemplateXML, which extends RestTemplate. Then override <code>doExecute(URI, HttpMethod, RequestCallback, ResponseExtractor&lt;T&gt;)</code>, and explicitly get <code>response-headers</code> and set <code>content-type</code> to <code>application/xml</code>. 

Now Spring reads the headers and knows that it is `application/xml'. It is kind of a hack but it works.

<pre><code>public class RestTemplateXML extends RestTemplate {

 @Override
 protected &lt;T&gt; T doExecute(URI url, HttpMethod method, RequestCallback requestCallback,
 ResponseExtractor&lt;T&gt; responseExtractor) throws RestClientException {

 logger.info( RestTemplateXML.class.getSuperclass().getSimpleName() + ".doExecute() is overridden");

 Assert.notNull(url, "'url' must not be null");
 Assert.notNull(method, "'method' must not be null");
 ClientHttpResponse response = null;
 try {
 ClientHttpRequest request = createRequest(url, method);
 if (requestCallback != null) {
 requestCallback.doWithRequest(request);
 }
 response = request.execute();

 // Set ContentType to XML
 response.getHeaders().setContentType(MediaType.APPLICATION_XML);

 if (!getErrorHandler().hasError(response)) {
 logResponseStatus(method, url, response);
 }
 else {
 handleResponseError(method, url, response);
 }
 if (responseExtractor != null) {
 return responseExtractor.extractData(response);
 }
 else {
 return null;
 }
 }
 catch (IOException ex) {
 throw new ResourceAccessException("I/O error on " + method.name() +
 " request for \"" + url + "\":" + ex.getMessage(), ex);
 }
 finally {
 if (response != null) {
 response.close();
 }
 }

 }

 private void logResponseStatus(HttpMethod method, URI url, ClientHttpResponse response) {
 if (logger.isDebugEnabled()) {
 try {
 logger.debug(method.name() + " request for \"" + url + "\" resulted in " +
 response.getRawStatusCode() + " (" + response.getStatusText() + ")");
 }
 catch (IOException e) {

 }
 }

This is not answering the problem but if anyone comes to this question when they stumble upon this exception of no suitable message converter found, here is my problem and solution.
In Spring 4.0.9, we were able to send this
<pre><code> JSONObject jsonCredential = new JSONObject();
 jsonCredential.put(APPLICATION_CREDENTIALS, data);

 HttpHeaders headers = new HttpHeaders();
 headers.setContentType(MediaType.APPLICATION_JSON);

ResponseEntity&lt;String&gt; res = restTemplate.exchange(myRestUrl), HttpMethod.POST,request, String.class);
</code></pre>
In Spring 4.3.5 release, we starting seeing errors with the message that converter was not found.
The way Convertors work is that if you have it in your classpath, they get registered.
Jackson-asl was still in classpath but was not being recognized by spring. We replaced Jackson-asl with faster-xml jackson core.
Once we added I could see the converter being registered.

blocks|key|4659350|text|除了所有的答案之外，如果您在期望其他内容(即application/json)时恰好收到响应text/html，则可能表明服务器端发生了错误(比如404)，返回的是错误页面而不是您的数据。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4659351|所以它发生在我的案例中。希望这能节省一些人的时间。|4659352|entityMap^0|M|G|1A|9|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]|$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|O|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|P|8|@]|D|@]|E|$]]]|I|$]]

In addition to all the answers, if you happen to receive in response <code>text/html</code> while you've expected something else (i.e. <code>application/json</code>), it may suggest that an error occurred on the server side (say 404) and the error page was returned instead of your data.

So it happened in my case. Hope it will save somebody's time.

blocks|key|4659382|text|Vadim+Zin4uk's+answer的一个改进是只使用现有的GsonHttpMessageConverter类，但调用setSupportedMediaTypes()+setter。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|4659383|对于spring+boot应用程序，这会导致向您的配置类添加以下内容：|4659384|@Bean

A refinement of <a href="https://stackoverflow.com/a/28041170/1484823">Vadim Zin4uk's answer</a> is just to use the existing GsonHttpMessageConverter class but invoke the setSupportedMediaTypes() setter.

For spring boot apps, this results into adding to following to your configuration classes:

<pre><code>@Bean
public GsonHttpMessageConverter gsonHttpMessageConverter(Gson gson) {
 GsonHttpMessageConverter converter = new GsonHttpMessageConverter();
 converter.setGson(gson);
 List&lt;MediaType&gt; supportedMediaTypes = converter.getSupportedMediaTypes();
 if (! supportedMediaTypes.contains(TEXT_PLAIN)) {
 supportedMediaTypes = new ArrayList&lt;&gt;(supportedMediaTypes);
 supportedMediaTypes.add(TEXT_PLAIN);
 converter.setSupportedMediaTypes(supportedMediaTypes);
 }
 return converter;
}
</code></pre>
